/*FrameRoundRect

Draws an outline inside a rounded rectangle. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

void FrameRoundRect (
   const Rect * r,
   short ovalWidth,
   short ovalHeight
);
Parameters
r

The rectangle that defines the rounded rectangle’s boundaries.
ovalWidth

The width of the oval defining the rounded corner.
ovalHeight

The height of the oval defining the rounded corner.
Discussion

Using the pattern, pattern mode, and size of the graphics pen for the current graphics port, the FrameRoundRect function draws an outline just inside the rounded rectangle bounded by the rectangle that you specify in the r parameter. The outline is as wide as the pen width and as tall as the pen height. The pen location does not change. 

Use the ovalWidth and ovalHeight parameters to specify the diameters of curvature for the corners of the rounded rectangle.

If a region is open and being formed, the outside outline of the new rounded rectangle is mathematically added to the region’s boundary.

/*SetRect

Assigns coordinates to a rectangle. 

void SetRect (
   Rect * r,

   short top,
   short right,

);
Parameters
r

A pointer to the rectangle to set.
left

The horizontal coordinate of the new upper-left corner of the rectangle.
top

The vertical coordinate of the new upper-left corner of the rectangle.
right

The horizontal coordinate of the new lower-right corner of the rectangle.
bottom

The vertical coordinate of the new lower-right corner of the rectangle.
Discussion

The SetRect function assigns the coordinates you specify in the left, top, right, and bottom parameters to the rectangle that you specify in the r parameter. This function is provided to help you shorten your program text. If you want a more readable text, at the expense of source text length, you can instead assign integers (or points) directly into the fields of a Rect structure.

You can use a rectangle to specify locations and sizes for various graphics operations.

If the points or rectangles supplied to this function are defined in a graphics port other than your current graphics port, you must convert them to the local coordinate system of your current graphics port. You can accomplish this by using the SetPort function to change to the graphics port containing the points or rectangles, using the LocalGlobal function to convert their locations to global coordinates, using SetPort to return to your starting graphics port, and then using the GlobalToLocal function to convert the locations of points or rectangles to the local coordinates of your current graphics port.

void EraseRect (

Parameters
r

The rectangle to erase.
Discussion

Using the patCopy pattern mode, the EraseRect function draws the interior of the rectangle that you specify in the r parameter with the background pattern for the current graphics port. This effectively erases the rectangle, making the shape blend into the background pattern of the graphics port. For example, use EraseRect to erase the port rectangle for a window before redrawing into the window.

/*CopyBits

Copies a portion of a bitmap or a pixel map from one graphics port or offscreen graphics world into another graphics port. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

void CopyBits (
   const BitMap * srcBits,
   const BitMap * dstBits,
   const Rect * srcRect,
   const Rect * dstRect,
   short mode,
   RgnHandle maskRgn
);
Parameters
srcBits

The source BitMap structure. 
dstBits

The destination BitMap structure.
srcRect

The source rectangle.
dstRect

The destination rectangle.
mode

One of the eight source modes in which the copy is to be performed. See Source, Pattern, and Arithmetic Transfer Mode Constants. The CopyBits function always dithers images when shrinking them between pixel maps on direct devices. 

When transferring pixels from a source pixel map to a destination pixel map, color QuickDraw interprets the source mode constants differently than basic QuickDraw does.

When you use CopyBits on a computer running color QuickDraw, you can also specify one of the transfer modes in the mode parameter.
maskRgn

A region to use as a clipping mask. You can pass a region handle to specify a mask region the resulting image is always clipped to this mask region and to the boundary rectangle of the destination bitmap. If the destination bitmap is the current graphics port’s bitmap, it is also clipped to the intersection of the graphics port’s clipping region and visible region. If you do not want to clip to a masking region, just pass NULL for this parameter. 
Discussion

The CopyBits function transfers any portion of a bitmap between two basic graphics ports, or any portion of a pixel map between two color graphics ports. Use CopyBits to move offscreen graphic images into an onscreen window, to blend colors for the image in a pixel map, and to shrink and expand images.

Specify a source bitmap in the srcBits parameter and a destination bitmap in the dstBits parameter. When copying images between color graphics ports, you must coerce each CGrafPort structure to a GrafPort structure, dereference the portBits fields of each, and then pass these “bitmaps” in the srcBits and dstBits parameters. If your application copies a pixel image from a color graphics port called MyColorPort, for example, you could specify (* GrafPtr(MyColorPort)).portBits in the srcBits parameter. In a CGrafPort structure, the high 2 bits of the portVersion field are set. This field, which shares the same position in a CGrafPort structure as the portBits.rowBytes field in a GrafPort structure, indicates to CopyBits that you have passed it a handle to a pixel map rather than a bitmap.

Using the srcRect and dstRect parameters, you can specify identically or differently sized source and destination rectangles; for differently sized rectangles, CopyBits scales the source image to fit the destination. If the bit image is a circle in a square source rectangle, and the destination rectangle is not square, the bit image appears as an oval in the destination. When you specify rectangles in the srcRect and dstRect parameters, use the local coordinate systems of, respectively, the source and destination graphics ports.

The CopyDeepMask function combines the functions of the CopyBits and CopyMask functions. 
Special Considerations

When you use the CopyBits function to transfer an image between pixel maps, the source and destination images may be of different pixel depths, of different sizes, and they may have different color tables. However, CopyBits assumes that the destination pixel map uses the same color table as the color table for the current GDevice structure. (This is because the Color Manager requires an inverse table for translating the color table from the source pixel map to the destination pixel map.) 

The CopyBits function applies the foreground and background colors of the current graphics port to the image in the destination pixel map (or bitmap), even if the source image is a bitmap. This causes the foreground color to replace all black pixels in the destination and the background color to replace all white pixels. To avoid unwanted coloring of the image, use the RGBForeColor function to set the foreground to black and use the RGBBackColor function to set the background to white before calling CopyBits.

The source bitmap or pixel map must not occupy more memory than half the available stack space. The stack space required by CopyBits is roughly five times the value of the rowBytes field of the source pixel map: one rowBytes value for the pixel map (or bitmap), an additional rowBytes value for dithering, another rowBytes value when stretching or shrinking the source pixel map into the destination, another rowBytes value for any color map changing, and a fifth additional rowBytes value for any color aliasing. If there is insufficient memory to complete a CopyBits operation in Color QuickDraw, the QDError function returns the result code –143.

If you use CopyBits to copy between two graphics ports that overlap, you must first use the LocalToGlobal function to convert to global coordinates, and then specify the global variable screenBits for both the srcBits and dstBits parameters.

The CopyBits function may move or purge memory blocks in the application heap; do not call this function at interrupt time.

If you are reading directly from a NuBus video card with a base address of Fs00000 and there is not a card in the slot (s–1) below it, CopyBits reads addresses less than the base address of the pixel map. This causes a bus error. To work around the problem, remap the baseAddr field of the pixel map in your video card to at least 20 bytes above the NuBus boundary; an address link of Fs000020 precludes the problem.

/*QDFlushPortBuffer

Calls the Quartz compositor to flush all new drawing in a Carbon window to the display. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

void QDFlushPortBuffer (
   CGrafPtr port,
   RgnHandle region
);
Parameters
port

A window port. If the port has no back buffer, or if the port is an offscreen or printing port, this function does nothing.
region

An update region. Under normal conditions, you should pass NULL to avoid the overhead of additional region operations.
Discussion

In Mac OS X, drawing in a window port updates a back buffer associated with the window. Updates to this buffer are accumulated in a list called the dirty region. 

The back buffer is automatically flushed to the display each time through the event loop. When the event loop does not get control soon enough—for example, during an animation sequence—you can call this function to flush the port buffer to the device immediately. 

When you call this function, there are several different execution paths:
If the region parameter is NULL, the dirty region is flushed—along with any Quartz 2D drawing operations marked for update by calls to CGContextSynchronize—and the dirty region is set to empty.
If the region parameter specifies an update region, the intersection of the dirty region and the update region is flushed—along with any Quartz 2D drawing operations marked for update by calls to CGContextSynchronize—and the flushed region is subtracted from the dirty region.

/*InsetRect

Shrinks or expands a rectangle. 

void InsetRect (

Parameters
r

A pointer to the rectangle to alter.
dh

The horizontal distance to move the left and right sides in toward or outward from the center of the rectangle.
dv

The vertical distance to move the top and bottom sides in toward or outward from the center of the rectangle.
Discussion

The InsetRect function shrinks or expands the rectangle that you specify in the r parameter: the left and right sides are moved in by the amount you specify in the dh parameter; the top and bottom are moved toward the center by the amount you specify in the dv parameter. If the value you pass in dh or dv is negative, the appropriate pair of sides is moved outward instead of inward. The effect is to alter the size by 2*dh horizontally and 2*dv vertically, with the rectangle remaining centered in the same place on the coordinate plane.

If the resulting width or height becomes less than 1, the rectangle is set to the empty rectangle (0,0,0,0).

If the points or rectangles supplied to this function are defined in a graphics port other than your current graphics port, you must convert them to the local coordinate system of your current graphics port. You can accomplish this by using the SetPort function to change to the graphics port containing the points or rectangles, using the LocalGlobal function to convert their locations to global coordinates, using SetPort to return to your starting graphics port, and then using the GlobalToLocal function to convert the locations of points or rectangles to the local coordinates of your current graphics port.

/*FrameRgn

Draws an outline inside a region. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

void FrameRgn (
   RgnHandle rgn
);
Parameters
rgn

A handle to the region to frame. 
Discussion

Using the current graphics port’s pen pattern, pattern mode, and pen size, the FrameRgn function draws an outline just inside the region whose handle you pass in the rgn parameter. The outline never goes outside the region boundary. The pen location does not change.

If a region is open and being formed, the outside outline of the region being framed is mathematically added to that region’s boundary.

This function depends on the local coordinate system of the current graphics port. If you draw a region in a graphics port different from the one in which you defined the region, it may not appear in the proper position in the graphics port.

If any horizontal or vertical line drawn through the region would intersect the region’s outline more than 50 times, the results of this graphics operation are undefined. The FrameRgn function in particular requires that there would be no more than 25 such intersections. 
Special Considerations

The FrameRgn function calls the functions CopyRgn, InsetRgn, and DiffRgn, so FrameRgn may temporarily use heap space that’s three times the size of the original region.

void RGBBackColor (
   const RGBColor * color
);
Parameters
color

An RGBColor structure. 
Discussion

If the current port is defined by a CGrafPort structure, QuickDraw supplies its rgbBkColor field with the RGB value that you specify in the color parameter, and places the pixel value most closely matching that color in the bkColor field. For indexed devices, the pixel value is an index to the current device’s CLUT. F or direct devices, the value is the 16-bit or 32-bit equivalent to the RGB value.

If the current port is defined by a GrafPort structure, basic QuickDraw supplies its fgColor field with a color value determined by taking the high bit of each of the red, green, and blue components of the color that you supply in the color parameter. Basic QuickDraw uses that 3-bit number to select a color from its eight-color system.

You can also use Palette Manager functions to set the background color.

To determine the current background color, use the GetBackColor function.

Because a pixel pattern already contains color, QuickDraw ignores the background color and foreground colors when your application draws with a pixel pattern. Use the PenPixPat function to assign a pixel pattern to the foreground pattern used by the graphics pen. Use the BackPixPat function to assign a pixel pattern as the background pattern for the current color graphics port. Use the FillCRect, FillCOval, FillCRoundRect, FillCArc, FillCRgn, and FillCPoly functions to fill shapes with a pixel pattern. 
Special Considerations

The RGBBackColor function may move or purge memory blocks in the application heap; do not call this function at interrupt time.

Parameters
displayID

A display identifier. If the identifier is not valid, the main display is used instead. For information about finding displays, see Quartz Display Services Reference.
Return Value

A new display port. The portBounds rectangle is the same size as the display. When you are finished using the port, you should call DisposePort to release it.
Discussion

This function returns a graphics port used to draw directly to a display. The pixel map for the new port is taken from the GDevice record corresponding to the display. There is no back buffer associated with the port.

Before calling this function, you should capture the display. For information about capturing displays, see Quartz Display Services Reference.

You should not call this function and then attempt to create a Quartz drawing environment inside the port. Instead, applications using Quartz 2D can call CGDisplayGetDrawingContext to obtain a context suitable for drawing directly to a captured display.

);
Parameters
width

The pen width, as an integer from 0 to 32,767. If you set the value to 0, the pen does not draw. Values less than 0 are undefined.
height

The pen height, as an integer from 0 to 32,767. If you set the value to 0, the pen does not draw. Values less than 0 are undefined.
Discussion

The PenSize function sets the width that you specify in the width parameter and the height that you specify in the height parameter for the graphics pen in the current graphics port. All subsequent calls to the Line and LineTo functions and to the functions that draw framed shapes in the current graphics port use the new pen dimensions.

You can get the current pen dimensions from the pnSize field of the current graphics port, where the width and height are stored as a Point structure.

This pen-manipulation function uses the local coordinate system of the current graphics port. Remember that each graphics port has its own pen, the state of which is stored in several fields of its GrafPort or CGrafPort structure.

);
Parameters
r

Upon input, a pointer to the rectangle to map; upon completion, the mapped rectangle.
srcRect

The rectangle containing the rectangle to map.
dstRect

The rectangle in which the new rectangle will be mapped.
Discussion

The MapRect function takes a rectangle within one rectangle and maps and scales it to another rectangle. In the r parameter, you specify a rectangle that lies within the rectangle that you specify in the srcRect parameter. By calling the MapPt function to map the upper-left and lower-right corners of the rectangle in the r parameter, MapRect maps and scales it to the rectangle that you specify in the dstRect parameter. The MapRect function returns the newly mapped rectangle in the r parameter. 
Special Considerations

If the points or rectangles supplied to this function are defined in a graphics port other than your current graphics port, you must convert them to the local coordinate system of your current graphics port. You can accomplish this by using the SetPort function to change to the graphics port containing the points or rectangles, using the LocalGlobal function to convert their locations to global coordinates, using SetPort to return to your starting graphics port, and then using the GlobalToLocal function to convert the locations of points or rectangles to the local coordinates of your current graphics port.

Parameters
srcRgnA

A handle to the first of two regions to compare. 
srcRgnB

A handle to the second of two regions to compare.
dstRgn

On return, a handle to the region holding the result.

This does not create the destination region; you must have already allocated memory for it by using the NewRgn function.

If the regions are coincident, XorRgn sets the destination region to the empty region defined by the rectangle (0,0,0,0).
Discussion

The XorRgn procedure calculates the difference between the union and the intersection of the regions whose handles you pass in the srcRgnA and srcRgnB parameters and places the result in the region whose handle you pass in the dstRgn parameter. 

This does not create the destination region; you must have already allocated memory for it by using the NewRgn function.

/*SetOrigin

Changes the coordinates of the window origin of the port rectangle of the current graphics port (basic or color). (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

void SetOrigin (
   short h,
   short v
);
Parameters
h

The horizontal coordinate of the upper-left corner of the port rectangle.
v

The vertical coordinate of the upper-left corner of the port rectangle.
Discussion

The SetOrigin function changes the coordinates of the upper-left corner of the current graphics port’s port rectangle to the values supplied by the h and v parameters. All other points in the current graphics port’s local coordinate system are calculated from this point. All subsequent drawing and calculation functions use the new coordinate system.

The SetOrigin function does not affect the screen; it does, however, affect where subsequent drawing inside the graphics port appears. The SetOrigin function does not offset the coordinates of the clipping region or the graphics pen, which therefore change position on the screen (unlike the boundary rectangle, port rectangle, and visible region, which don’t change position onscreen).

Because SetOrigin does not move the window’s clipping region, use the GetClip function to store your clipping region immediately after your first call to SetOrigin—if you use clipping regions in your windows. Before calling your own window-drawing function, use the ClipRect function to define a new clipping region—to avoid drawing over your scroll bars, for example. After calling your own window-drawing function, use the SetClip function to restore the original clipping region. You can then call SetOrigin again to restore the window origin to a horizontal coordinate of 0 and a vertical coordinate of 0 with your original clipping region intact. 

All other functions in the Macintosh Toolbox and Operating System preserve the local coordinate system of the current graphics port. The SetOrigin function is useful for readjusting the coordinate system after a scrolling operation. 

Note that the Window Manager and Control Manager always assume the window’s upper-left point has a horizontal coordinate of 0 and a vertical coordinate of 0 when they draw in a window. Therefore, if you use SetOrigin to change the window origin, be sure to use SetOrigin again to return the window origin to a horizontal coordinate of 0 and a vertical coordinate of 0 before using any Window Manager or Control Manager functions.

The SectRgn function does not create a destination region; you must have already allocated memory for it by using the NewRgn function. 

The destination region may be one of the source regions, if desired.
Discussion

The SectRgn procedure calculates the intersection of the two regions whose handles you pass in the srcRgnA and srcRgnB parameters, and it places the intersection in the region whose handle you pass in the dstRgn parameter. If the regions do not intersect, or one of the regions is empty, SectRgn sets the destination to the empty region defined by the rectangle (0,0,0,0).

procs

Upon completion, a CQDProcs structure with fields that point to QuickDraw’s standard low-level functions. You can change one or more fields to point to your own functions and then set the color graphics port to use this modified CQDProcs structure. 
Discussion

For each shape that QuickDraw can draw, certain functions perform basic graphics operations on the shape: framing, painting, erasing, inverting, and filling. These functions, in turn, call a low-level drawing function for the shape.

The grafProcs field determines which low-level functions are called. If that field contains a value of NULL, the standard functions are called. You can set the grafProcs field to point to a structure of pointers to your own functions, and either completely override the standard ones or call them after your functions have modified their parameters as necessary.

The SetStdCProcs function sets all the fields of the CQDProcs structure to point to the standard functions. You can then reset the ones with which you are concerned.

The functions you install in the CDQProcs structure must have the same calling sequences as the standard basic QuickDraw functions.

When drawing in a color graphics port, your application must always use SetStdCProcs instead of SetStdProcs.

/*BackPat

Changes the bit pattern used as the background pattern by the current graphics port. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

void BackPat (
   const Pattern * pat
);
Parameters
pat

A bit pattern, as defined by a Pattern structure. 
Discussion

The BackPat function sets the bit pattern defined in the Pattern structure, which you specify in the pat parameter, to be the background pattern. (The standard bit patterns white, black, gray, ltGray, and dkGray are predefined; the initial background pattern for the graphics port is white.) This pattern is stored in the bkPat field of a GrafPort structure.

The BackPat function also sets a bit pattern for the background color in a color graphics port. The BackPat function creates a handle, of type PixPatHandle, for the bit pattern and stores this handle in the bkPixPat field of the CGrafPort structure. As in basic graphics ports, Color QuickDraw draws patterns in color graphics ports at the time of drawing, not at the time you use PenPat to set the pattern.

To define your own patterns, you typically create pattern, ‘PAT’, or pattern list, ‘PAT#’, resources. 
Special Considerations

The BackPat function may move or purge memory blocks in the application heap; do not call this function at interrupt time.

/*LockPortBits

Acquires an exclusive lock on the back buffer for a Carbon window. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

OSErr LockPortBits (
   GrafPtr port
);
Parameters
port

A window port.
Return Value

A result code. If noErr, the window’s back buffer is locked and available for direct access. 
Discussion

In Mac OS X, a Carbon window’s port bits are in a back buffer shared by the application and the Quartz compositor (sometimes called the window server). When an application needs to update this buffer, the Quartz compositor must be locked out temporarily. You can use this function together with UnlockPortBits to acquire and release an exclusive lock.

If you’re using QuickDraw or Quartz 2D to draw in a window, you do not need to call this function—buffer locks are handled for you automatically. If you’re writing code that reads or modifies the port bits directly, you should bracket your code with calls to this function and UnlockPortBits.

Nested calls to this function for the same port are permitted. For a given port, if you call LockPortBits n times, the lock is actually released after the nth balancing call to UnlockPortBits.

You should not call any QuickTime functions while holding the lock. To avoid degrading the user experience, you should release the lock as quickly as possible. 

In Mac OS 9, this function does nothing and returns noErr.

void PenPat (

);
Parameters
pat

A bit pattern, as defined by a Pattern structure. 
Discussion

The PenPat function sets the graphics pen to use the bit pattern defined in the Pattern structure that you specify in the pat parameter. (The standard patterns white, black, gray, ltGray, and dkGray are predefined; the initial bit pattern for the pen is black.) This pattern is stored in the pnPat field of a GrafPort structure. The QuickDraw painting functions (such as PaintRect) also use the pen’s pattern when drawing a shape.

The PenPat function also sets a bit pattern for the graphics pen in a color graphics port. The PenPat function creates a handle, of type PixPatHandle, for the bit pattern and stores this handle in the pnPixPat field of the CGrafPort structure. This pattern always uses the graphics port’s current foreground and background colors.

To define your own patterns, you typically create pattern, ‘PAT’, or pattern list, ‘PAT#’, resources.

Parameters
pnState

A PenState structure previously created with the GetPenState function. The SetPenState function sets the graphics pen’s location, size, pattern, and pattern mode in the current graphics port to the values stored in this structure. 
Discussion

This pen-manipulation function uses the local coordinate system of the current graphics port. Remember that each graphics port has its own pen, the state of which is stored in several fields of its GrafPort or CGrafPort structure.

Discussion

If the points or rectangles supplied to this function are defined in a graphics port other than your current graphics port, you must convert them to the local coordinate system of your current graphics port. You can accomplish this by using the SetPort function to change to the graphics port containing the points or rectangles, using the LocalGlobal function to convert their locations to global coordinates, using SetPort to return to your starting graphics port, and then using the GlobalToLocal function to convert the locations of points or rectangles to the local coordinates of your current graphics port.

ShowPen is called by the functions CloseRgn , ClosePoly , and ClosePicture.

The ShowPen function increments the pnVis field of the current graphics port. For 0 or positive values, the pen drawing shows on the screen.

For example, if you have used the HidePen function to decrement the pnVis field from 0 to –1, use the ShowPen function to make its value 0 so that QuickDraw resumes drawing on the screen. Subsequent calls to ShowPen increment pnVis beyond 0, so every call to ShowPen should be balanced by a call to HidePen. 

This pen-manipulation function uses the local coordinate system of the current graphics port. Remember that each graphics port has its own pen, the state of which is stored in several fields of its GrafPort or CGrafPort structure.

The horizontal distance to move points on the left and right boundaries in toward or outward from the center.
dv

The vertical distance to move points on the top and bottom boundaries in toward or outward from the center.
Discussion

The InsetRgn function moves all points on the region boundary of the region whose handle you pass in the rgn parameter inward by the vertical distance that you specify in the dv parameter and by the horizontal distance that you specify in the dh parameter. If you specify negative values for dh or dv, the InsetRgn function moves the points outward in that direction. 

The InsetRgn function leaves the region’s center at the same position, but moves the outline in (for positive values of dh and dv) or out (for negative values of dh and dv). Using InsetRgn on a rectangular region has the same effect as using the InsetRect function.

Discussion

Before you modify a ColorTable structure, change its ctSeed field to invalidate it. To do this, use the CTabChanged function.

The GetCTable function recognizes a number of standard 'clut' resource IDs. You can obtain the default grayscale color table for a given pixel depth by calling GetCTable, adding 32 (decimal) to the pixel depth, and passing these values in the ctID parameter:
A pixel depth of 1Pass a resource ID of 33. Color table composition: black, white. 
A pixel depth of 2Pass a resource ID of 34. Color table composition: black, 33% gray, 66% gray, white.

A pixel depth of 8Pass a resource ID of 40. Color table composition: black, 254 shades of gray, white. 

For full color, obtain the default color tables by adding 64 to the pixel depth and passing these values in the ctID parameter:

Discussion

The SectRect function calculates the rectangle that delineates the intersection of the two rectangles you specify in the src1 and src2 parameters. Rectangles that touch at a line or a point are not considered intersecting, because their intersection rectangle (actually, in this case, an intersection line or point) does not enclose any pixels in the bit image.

If the rectangles do not intersect, the destination rectangle is set to (0,0,0,0). The SectRect function works correctly even if one of the source rectangles is also the destination.

void RGBForeColor (
   const RGBColor * color
);
Parameters
color

An RGBColor structure. 
Discussion

If the current port is defined by a CGrafPort structure, QuickDraw supplies its rgbFgColor field with the RGB value that you specify in the color parameter, and places the pixel value most closely matching that color in the fgColor field. For indexed devices, the pixel value is an index to the current device’s CLUT. For direct devices, the value is the 16-bit or 32-bit equivalent to the RGB value.

If the current port is defined by a GrafPort structure, basic QuickDraw supplies its fgColor field with a color value determined by taking the high bit of each of the red, green, and blue components of the color that you supply in the color parameter. Basic QuickDraw uses that 3-bit number to select a color from its eight-color system. 

You can also use Palette Manager functions to set the foreground color.

To determine the current foreground color, use the GetForeColor function.

QuickDraw ignores the foreground and background colors when your application draws with a pixel pattern. Assign a pixel pattern to the foreground pattern used by the graphics pen; by using the BackPixPat function to assign a pixel pattern as the background pattern for the current color graphics port; and by using the FillCRect, FillCOval, FillCRoundRect, FillCArc, FillCRgn, and FillCPoly functions to fill shapes with a pixel pattern. 
Special Considerations

The RGBForeColor function may move or purge memory blocks in the application heap; do not call this function at interrupt time.
Version Notes

The RGBForeColor function is available for basic QuickDraw only in System 7. To set the foreground color for basic graphics ports on older versions of system software, use the ForeColor function.

/*NewRgn

Begins creating a new region. (Deprecated in Mac OS X v10.4.)

RgnHandle NewRgn ();
Return Value

A handle to the new region. 
Discussion

The NewRgn function allocates space for a new, variable-size region and initializes it to the empty region defined by the rectangle (0,0,0,0). This is the only function that creates a new region; other functions merely alter the size or shape of existing regions.

To begin defining a region, use the OpenRgn function.

If the points or rectangles supplied to this function are defined in a graphics port other than your current graphics port, you must convert them to the local coordinate system of your current graphics port. You can accomplish this by using the SetPort function to change to the graphics port containing the points or rectangles, using the LocalGlobal function to convert their locations to global coordinates, using SetPort to return to your starting graphics port, and then using the GlobalToLocal function to convert the locations of points or rectangles to the local coordinates of your current graphics port. 
Special Considerations

The NewRgn function may move or purge memory blocks in the application heap; do not call this function at interrupt time.

Use the Memory Manager function MaxMem to determine whether the memory for the region is valid before using NewRgn.

Ensure that the memory for a region is valid before calling this function to manipulate that region if there isn’t sufficient memory, the system may crash. Regions are limited to 32 KB in size in basic QuickDraw and 64 KB in color QuickDraw. Before defining a region, you can use the Memory Manager function MaxMem to determine whether the memory for the region is valid. You can determine the current size of an existing region by calling the Memory Manager function GetHandleSize. When you record drawing operations in an open region, the resulting region description may overflow the 32 KB or 64 KB limit. Should this happen in color QuickDraw, the QDError function returns the result code regionTooBigError.

/*OpenRgn

Begins defining a region. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

void OpenRgn ();
Discussion

The OpenRgn function allocates temporary memory to start saving lines and framed shapes for processing as a region definition. Call OpenRgn only after initializing a region with the NewRgn function.

The NewRgn function stores the definition for a region in a Region structure.

While a region is open, all calls to Line, LineTo, and the functions that draw framed shapes (except arcs) affect the outline of the region. Only the line endpoints and shape boundaries affect the region definition—the pattern mode, pattern, and size do not affect it.

When you are finished defining the region, call the CloseRgn function.

The OpenRgn function calls HidePen, so no drawing occurs on the screen while the region is open (unless you call ShowPen just after OpenRgn, or you called ShowPen previously without balancing it by a call to HidePen). Since the pen hangs below and to the right of the pen location, drawing lines with even the smallest pen changes pixels that lie outside the region you define.

The outline of a region is mathematically defined and infinitely thin, and it separates the bit or pixel image into two groups of pixels: those within the region and those outside it. 

A region should consist of one or more closed loops. Each framed shape itself constitutes a loop. Any lines drawn with the Line or LineTo function should connect with each other or with a framed shape. Even if the onscreen presentation of a region is clipped, the definition of a region is not; you can define a region anywhere on the coordinate plane with complete disregard for the location of various graphics port entities on that plane.

When a region is open, the current graphics port’s rgnSave field contains a handle to information related to the region definition. If you want to temporarily disable the collection of lines and shapes, you can save the current value of this field, set the field to NULL, and later restore the saved value to resume the region definition. Also, calling SetPort while a region is being formed discontinues formation of the region until another call to SetPort resets the region’s original graphics port.

If the points or rectangles supplied to this function are defined in a graphics port other than your current graphics port, you must convert them to the local coordinate system of your current graphics port. You can accomplish this by using the SetPort function to change to the graphics port containing the points or rectangles, using the LocalGlobal function to convert their locations to global coordinates, using SetPort to return to your starting graphics port, and then using the GlobalToLocal function to convert the locations of points or rectangles to the local coordinates of your current graphics port. 
Special Considerations

Regions are limited to 32 KB in size in basic QuickDraw and 64 KB in Color QuickDraw. You can determine the current size of an existing region by calling the Memory Manager function GetHandleSize. When you structure drawing operations in an open region, the resulting region description may overflow the 32 KB or 64 KB limit. Should this happen in Color QuickDraw, the QDError function returns the result code regionTooBigError. 

Do not call OpenRgn while another region or a polygon is already open. When you are finished constructing the region, use the CloseRgn function, which is described next.

The OpenRgn function may move or purge memory blocks in the application heap; do not call this function at interrupt time.

void CloseRgn (

);
Parameters
dstRgn

The handle to the region to close. This handle should be a region handle returned by the NewRgn function. 
Discussion

The CloseRgn function stops the collection of lines and framed shapes, organizes them into a region definition, and saves the result in the region whose handle you pass in the dstRgn parameter. 

The CloseRgn function does not create the destination region; you must have already allocated space for it by using the OpenRgn function. The CloseRgn function calls the ShowPen function, balancing the call to the HidePen function made by OpenRgn. 

When you no longer need the memory occupied by the region, use the DisposeRgn function.

If the points or rectangles supplied to this function are defined in a graphics port other than your current graphics port, you must convert them to the local coordinate system of your current graphics port. You can accomplish this by using the SetPort function to change to the graphics port containing the points or rectangles, using the LocalGlobal function to convert their locations to global coordinates, using SetPort to return to your starting graphics port, and then using the GlobalToLocal function to convert the locations of points or rectangles to the local coordinates of your current graphics port. 
Special Considerations

Regions are limited to 32 KB in size in basic QuickDraw and 64 KB in Color QuickDraw. When you structure drawing operations in an open region, the resulting region description may overflow this limit. Should this happen in Color QuickDraw, the QDError function returns the result code regionTooBigError.

A pointer to the rectangle to alter.
dh

The horizontal distance to move the left and right sides in toward or outward from the center of the rectangle.
dv

The vertical distance to move the top and bottom sides in toward or outward from the center of the rectangle.
Discussion

The InsetRect function shrinks or expands the rectangle that you specify in the r parameter: the left and right sides are moved in by the amount you specify in the dh parameter; the top and bottom are moved toward the center by the amount you specify in the dv parameter. If the value you pass in dh or dv is negative, the appropriate pair of sides is moved outward instead of inward. The effect is to alter the size by 2*dh horizontally and 2*dv vertically, with the rectangle remaining centered in the same place on the coordinate plane.

If the resulting width or height becomes less than 1, the rectangle is set to the empty rectangle (0,0,0,0).

If the points or rectangles supplied to this function are defined in a graphics port other than your current graphics port, you must convert them to the local coordinate system of your current graphics port. You can accomplish this by using the SetPort function to change to the graphics port containing the points or rectangles, using the LocalGlobal function to convert their locations to global coordinates, using SetPort to return to your starting graphics port, and then using the GlobalToLocal function to convert the locations of points or rectangles to the local coordinates of your current graphics port.

Discussion

The OffsetRect function moves the rectangle that you specify in the r parameter by adding the value you specify in the dh parameter to each of its horizontal coordinates and the value you specify in the dv parameter to each of its vertical coordinates. If the dh and dv parameters are positive, the movement is to the right and down; if either is negative, the corresponding movement is in the opposite direction.

Parameters
picFrame

The bounding rectangle for the picture. The DrawPicture function uses this rectangle to scale the picture if you draw it into a destination rectangle of a different size.
Return Value

A handle to a new Picture structure. OpenPicture collects your subsequent drawing commands in this structure. Use this handle when referring to the picture in subsequent functions, such as the DrawPicture function. 
Discussion

The OpenPicture function, which was created for earlier versions of system software, is described here for completeness. Use the OpenPicture function to begin defining a picture. 

The OpenPicture function calls the HidePen function, so no drawing occurs on the screen while the picture is open (unless you call the ShowPen function just after OpenPicture or you called ShowPen previously without balancing it by a call to HidePen).

The OpenPicture function creates pictures in the version 2 format on computers with Color QuickDraw when the current graphics port is a color graphics port. Pictures created in this format support color drawing operations at 72 dpi. On computers supporting only basic QuickDraw, or when the current graphics port is a basic graphics port, this function creates pictures in version 1 format. Pictures created in version 1 format support only black-and-white drawing operations at 72 dpi.

When defining a picture, you can use all other QuickDraw drawing functions, with the exception of CopyMask, CopyDeepMask, SeedFill, SeedCFill, CalcMask, and CalcCMask. You can also use the PicComment function to include picture comments in your picture definition.

After defining the picture, close it by using the ClosePicture function. To draw the picture, use the DrawPicture function. 
Special Considerations

The version 2 and version 1 picture formats support only 72-dpi resolution. The OpenCPicture function creates pictures in the extended version 2 format. The extended version 2 format, which is created by the OpenCPicture function on all Macintosh computers running System 7, permits your application to specify additional resolutions when creating images.

Version 1 pictures are limited to 32 KB. You can determine the picture size while it is being formed by calling the Memory Manager function GetHandleSize.

Parameters
port

A color graphics port in which to draw. Offscreen graphics worlds with pixel depths of 1, 2, 4, and 8 are not supported. When using Quartz 2D to draw in a offscreen graphics world, alpha information is always ignored.
contextPtr

A pointer to your storage for a Quartz context. Upon completion, contextPtr points to a context associated with the port. The context matches the port’s pixel depth, width, and height. Otherwise the context is in a default state and does not necessarily match other port attributes such as foreground color, background color, or clip region.

You should not retain or release the context. When you are finished using the context, you should call QDEndCGContext.
Return Value

A result code. If noErr, the context was successfully initiated.
Discussion

Applications running in Mac OS X can use Quartz 2D to draw in a QuickDraw graphics port. When you call this function, you obtain a Quartz context that’s associated with the specified port. To improve performance, contexts returned by this function are cached and reused during subsequent calls whenever possible. 

Each block of Quartz 2D drawing code in your application should be surrounded by calls to this function and QDEndCGContext. Nested calls to this function for the same graphics port are not permitted—that is, for a given port you should not call this function more than once without an intervening call to QDEndCGContext.

While the Quartz context is in use, all Quickdraw imaging operations in the associated graphics port are disabled. This is done because the operations would fail during printing.

Discussion

All fields of the PixMap structure are copied from the current device’s PixMap structure except the color table.

Typically, you do not need to call this function because PixMap structures are created for you when you create a window using the Window Manager functions NewCWindow and GetNewCWindow and when you create an offscreen graphics world with the NewGWorld function. 

If your application creates a pixel map, your application must initialize the PixMap structure’s color table to describe the pixels. Use the GetCTable function to read such a table from a resource file. Use the DisposeCTable function to dispose of the PixMap structure’s color table and replace it with the one returned by GetCTable.

Parameters

The horizontal coordinate of the upper-left corner of the rectangle to set as the new region.
top

The vertical coordinate of the upper-left corner of the rectangle to set as the new region.
right

The horizontal coordinate of the lower-right corner of the rectangle to set as the new region.
bottom

The vertical coordinate of the lower-right corner of the rectangle to set as the new region.
Discussion

The SetRectRgn function destroys the previous structure of the region whose handle you pass in the rgn parameter, and it then sets the new structure to the rectangle that you specify in the left, top, right, and bottom parameters. If you specify an empty rectangle (that is, right is greater than or equal to left or bottom = top), the SetRectRgn function sets the region to the empty region defined by the rectangle (0,0,0,0).

As an alternative to the SetRectRgn function, you can change the structure of an existing region to that of a rectangle by using the RectRgn function, which accepts as a parameter a rectangle instead of four coordinates. 

If the points or rectangles supplied to this function are defined in a graphics port other than your current graphics port, you must convert them to the local coordinate system of your current graphics port. You can accomplish this by using the SetPort function to change to the graphics port containing the points or rectangles, using the LocalGlobal function to convert their locations to global coordinates, using SetPort to return to your starting graphics port, and then using the GlobalToLocal function to convert the locations of points or rectangles to the local coordinates of your current graphics port.

void InvertRect (
   const Rect * r
);
Parameters
r

The rectangle whose enclosed pixels are to be inverted.
Discussion

The InvertRect function inverts the pixels enclosed by the rectangle that you specify in the r parameter. Every white pixel becomes black and every black pixel becomes white. The pen location does not change. 
Special Considerations

The InvertRect function was designed for 1-bit images in basic graphics ports. This function operates on color pixels in color graphics ports, but the results are predictable only with direct pixels or 1-bit pixel maps. For indexed pixels, Color QuickDraw performs the inversion on the pixel indexes, which means the results depend entirely on the contents of the CLUT. The eight colors used in basic QuickDraw are stored in a color table represented by the global variable QDColors. To display those eight basic QuickDraw colors on an indexed device, Color QuickDraw uses the Color Manager to obtain indexes to the colors in the CLUT that best map to the colors in the QDColors color table. Because the index, not the color value, is inverted, the results are unpredictable.

Inversion works better for direct pixels. Inverting a pure green, for example, that has red, green, and blue component values of $0000, $FFFF, and $0000 results in magenta, which has component values of $FFFF, $0000, and $FFFF.

Discussion

The value Random returns depends solely on the global variable randSeed, which the QuickDraw InitGraf function initializes to 1. Each time the Random function executes, it uses a numerical algorithm to change the value of randSeed to prevent it from returning the same value each time it is called.

To prevent your application from generating the same sequence of pseudo-random numbers each time it is executed, initialize the randSeed global variable, when your application starts up, to a volatile long word variable such as the current date and time. If you would like to generate the same sequence of pseudo-random numbers twice, on the other hand, simply set randSeed to the same value before calling Random for each sequence.

gd

A handle to a GDevice structure. 
Discussion

Your application won’t generally need to use this function, because when your application draws into a window on one or more screens, Color QuickDraw automatically switches GDevice structures as appropriate; and when your application needs to draw into an offscreen graphics world, it can use the SetGWorld function to set the graphics port as well as the GDevice structure for the offscreen environment. However, if your application uses the SetPort function instead of the SetGWorld function to set the graphics port to or from an offscreen graphics world, then your application must use SetGDevice in conjunction with SetPort.

A handle to the currently active device is kept in the global variable TheGDevice.

Discussion

/*PenMode

void PenMode (
   short mode
);
Parameters
mode

The pattern mode. See Source, Pattern, and Arithmetic Transfer Mode Constants.
Discussion

Using the pattern mode you specify in the mode parameter, the PenMode function sets the manner in which the pattern of the graphics pen is transferred onto the bitmap (or pixel map) when you draw lines or shapes in the current graphics port.

If you specify a source mode (such as one used with the CopyBits function) instead of a pattern mode, no drawing is performed.

The current pattern mode is stored in the pnMode field of the current graphics port. The initial pattern mode value is patCopy, in which the pen pattern is copied directly to the bitmap.

To use highlighting, add the hilite constant or its value to the source or pattern mode:

With highlighting, QuickDraw replaces the background color with the highlight color when your application draws or copies images between graphics ports. This has the visual effect of using a highlighting pen to select the object. (The global variable HiliteRGB is read from parameter RAM when the machine starts. Basic graphics ports use the color stored in the HiliteRGB global variable as the highlight color. Color graphics ports default to the HiliteRGB global variable, but can be overridden by the HiliteColor function.

This pen-manipulation function uses the local coordinate system of the current graphics port. Remember that each graphics port has its own pen, the state of which is stored in several fields of its GrafPort or CGrafPort structure. If you draw in one graphics port, change to another, and return to the first, the pen for the first graphics port has the same state as when you left it. 
Special Considerations

When your application draws with a pixel pattern, Color QuickDraw ignores the pattern mode and simply transfers the pattern directly to the pixel map without regard to the foreground and background colors.

The results of inverting a pixel are predictable only with direct pixels or 1-bit pixel maps. For indexed pixels, Color QuickDraw performs the inversion on the pixel indexes, which means the results depend entirely on the contents of the color table. The eight colors used in basic QuickDraw are stored in a color table represented by the global variable QDColors. To display those eight basic QuickDraw colors on an indexed device, Color QuickDraw uses the Color Manager to obtain indexes to the colors in the CLUT that best map to the colors in the QDColors color table.

void SetClip (
   RgnHandle rgn
);
Parameters
rgn

A handle to a region. The SetClip function makes this region the clipping region of the current graphics port. The SetClip function doesn’t change the region handle, but instead affects the clipping region itself. 
Discussion

Since SetClip copies the specified region into the current graphics port’s clipping region, any subsequent changes you make to the region specified in the rgn parameter do not affect the clipping region of the graphics port.

The initial clipping region of a graphics port is an arbitrarily large rectangle. You can set the clipping region to any arbitrary region, to aid you in drawing inside the graphics port—for example, to avoid drawing over scroll bars when drawing into a window, you could define a clipping region that excludes the scroll bars. 

You can use the GetClip and SetClip functions to preserve the current clipping region: use GetClip to save the current port’s clipping region, and use SetClip to restore it.

All other system software functions preserve the current clipping region.

/*DrawPicture

void DrawPicture (
   PicHandle myPicture,
   const Rect * dstRect
);
Parameters
myPicture

A handle to the picture to be drawn. You must access a picture through its handle. 

When creating pictures, the OpenCPicture and OpenPicture functions return their handles. You can use the GetPicture function to get a handle to a QuickDraw picture stored in a 'PICT' resource. To get a handle to a QuickDraw picture stored in a 'PICT' file, you must use File Manager functions. To get a picture stored in the scrap, use the Scrap Manager function GetScrap to get a handle to its data and then coerce this handle to one of type PicHandle.

dstRect

A destination rectangle, specified in coordinates local to the current graphics port, in which to draw the picture. The DrawPicture function shrinks or expands the picture as necessary to align the borders of its bounding rectangle with the rectangle you specify in this parameter. To display a picture at a resolution other than that at which it was created, your application should compute an appropriate destination rectangle by scaling its width and height by the following factor:

scale factor = destination resolution / source resolution

For example, if a picture was created at 300 dpi and you want to display it at 75 dpi, then your application should compute the destination rectangle width and height as 1/4 of those of the picture’s bounding rectangle. Use the GetPictInfo function to gather information about a picture. The PictInfo structure returned by GetPictInfo returns the picture’s resolution in its hRes and vRes fields. The sourceRect field contains the bounding rectangle for displaying the image at its optimal resolution.
Discussion

Within the rectangle that you specify in the dstRect parameter, the DrawPicture function draws the picture that you specify in the myPicture parameter. 

The DrawPicture function passes any picture comments to the StdComment function pointed to by the commentProc field of the CQDProcs or QDProcs structure, which in turn is pointed to by the grafProcs field of a CGrafPort or GrafPort structure. The default StdComment function provided by QuickDraw does no comment processing whatsoever. If you want to process picture comments when drawing a picture, use the SetStdCProcs function to assist you in changing the CQDProcs structure and use the SetStdProcs function to assist you in changing the QDProcs structure. 
Special Considerations

Always use the ClipRect function to specify a clipping region appropriate for your picture before defining it with the OpenCPicture (or OpenPicture) function. If you do not use ClipRect to specify a clipping region, OpenCPicture uses the clipping region specified in the current graphics port. If the clipping region is very large (as it is when a graphics port is initialized) and you want to scale the picture, the clipping region can become invalid when DrawPicture scales the clipping region—in which case, your picture will not be drawn. On the other hand, if the graphics port specifies a small clipping region, part of your drawing may be clipped when DrawPicture draws it. Setting a clipping region equal to the port rectangle of the current graphics port always sets a valid clipping region.

When it scales, DrawPicture changes the size of the font instead of scaling the bits. However, the widths used by bitmap fonts are not always linear. For example, the 12-point width isn’t exactly 1/2 of the 24-point width. This can cause lines of text to become slightly longer or shorter as the picture is scaled. The difference is often insignificant, but if you are trying to draw a line of text that fits exactly into a box (a spreadsheet cell, for example), the difference can become noticeable to the user—most typically, at print time. The easiest way to avoid such problems is to specify a destination rectangle that is the same size as the bounding rectangle for the picture. Otherwise, your application may need to directly process the opcodes in the picture instead of using DrawPicture.

You may also have disappointing results if the fonts contained in an image are not available on the user’s system. Before displaying a picture, your application may want to use the Picture Utilities to determine what fonts are contained in the picture, and then use Font Manager functions to determine whether the fonts are available on the user’s system. If they are not, you can use Dialog Manager functions to display an alert box warning the user of display problems.

If there is insufficient memory to draw a picture in Color QuickDraw, the QDError function returns the result code noMemForPictPlaybackErr.

You should use this function only when absolutely necessary—it’s relatively inefficient when compared to Quartz 2D clipping functions such as CGContextClipToRect.

Discussion

If you’re using Quartz 2D to draw in a graphics port and SetOrigin is called to change the port’s origin, you can call this function to maintain the correspondence between the context’s origin and the lower-left corner of the portBounds rectangle.

When you call this function:

Paints a region with the graphics pen’s pattern and pattern mode. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

void PaintRgn (
   RgnHandle rgn
);
Parameters
rgn

A handle to the region to paint. 
Discussion

Using the pen pattern and pattern mode for the current graphics port, the PaintRgn function draws the interior of the region whose handle you pass in the rgn parameter. The pen location does not change.

This function depends on the local coordinate system of the current graphics port. If you draw a region in a graphics port different from the one in which you defined the region, it may not appear in the proper position in the graphics port.

If any horizontal or vertical line drawn through the region would intersect the region’s outline more than 50 times, the results of this graphics operation are undefined. 

Use FillRgn to draw the interior of a region with a pen pattern different from that for the current graphics port.

/*HidePen

Makes the graphics pen invisible, so that pen drawing doesn’t show on the screen. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

void HidePen ();
Discussion

The HidePen function is called by the OpenRgn , OpenPicture, and OpenPoly functions so that you can create regions, pictures, and polygons without drawing on the screen.

The HidePen function decrements the pnVis field of the current graphics port. The pnVis field is initialized to 0 by the OpenPort function. Whenever pnVis is negative, the pen does not draw on the screen. The pnVis field keeps track of the number of times the pen has been hidden to compensate for nested calls to the HidePen and ShowPen functions. 

Every call to HidePen should be balanced by a subsequent call to ShowPen. 

This pen-manipulation function uses the local coordinate system of the current graphics port. Remember that each graphics port has its own pen, the state of which is stored in several fields of its GrafPort or CGrafPort structure. If you draw in one graphics port, change to another, and return to the first, the pen for the first graphics port has the same state as when you left it.

/*UnionRgn

Calculates the union of two regions. 

void UnionRgn (

Parameters
srcRgnA

A handle to the first of two regions whose union is to be determined. 
srcRgnB

A handle to the second of two regions whose union is to be determined.
dstRgn

On return, a handle to the region holding the resulting union area. If both regions are empty, UnionRgn sets the destination to the empty region defined by the rectangle (0,0,0,0).

The UnionRgn function does not create the destination region; you must have already allocated memory for it by using the NewRgn function.

The destination region may be one of the source regions, if desired.
Discussion

The UnionRgn procedure calculates the union of the two regions whose handles you pass in the srcRgnA and srcRgnB parameters, and it places the union in the region whose handle you pass in the dstRgn parameter. If both regions are empty, UnionRgn sets the destination to the empty region defined by the rectangle (0,0,0,0).

The UnionRgn procedure does not create the destination region; you must have already allocated memory for it by using the NewRgn function.

Parameters
pm

A handle to the PixMap structure. 
Discussion

The SetPortPix function replaces the portPixMap field of the current CGrafPort structure with the handle you specify in the pm parameter. 

Typically, your application does not need to call this function.

The SetPortPix function is analogous to the basic QuickDraw function SetPortBits, which sets the bitmap for the current basic graphics port. The SetPortPix function has no effect when used with a basic graphics port. Similarly, SetPortBits has no effect when used with a color graphics port.

Both SetPortPix and SetPortBits allow you to perform drawing and calculations on a buffer other than the screen. However, instead of using these functions, use the offscreen graphics capabilities.

Parameters
color

On return, the RGBColor structure for the current foreground color. 
Discussion

This function operates for graphics ports defined by both the GrafPort and CGrafPort structures. If the current graphics port is defined by a CGrafPort structure, the returned value is taken directly from the rgbFgColor field. 

If the current graphics port is defined by a GrafPort structure, then only eight possible RGB values can be returned. These eight values are determined by the values in a global variable named QDColors, which is a handle to a color table containing the current QuickDraw colors.

Parameters
rgn

dh

The horizontal distance to move the region.
dv

The vertical distance to move the region.
Discussion

The OffsetRgn function moves the region whose handle you pass in the rgn parameter by adding the value you specify in the dh parameter to the horizontal coordinates of all points of its region boundary, and by adding the value you specify in the dv parameter to the vertical coordinates of all points of its region boundary. If the values of dh and dv are positive, the movement is to the right and down; if either is negative, the corresponding movement is in the opposite direction. The region retains its size and shape. This does not affect the screen unless you subsequently call a function to draw the region.

The OffsetRgn function is an especially efficient operation, because most of the data defining a region is stored relative to the rgnBBox field in its Region structure and so is not actually changed by OffsetRgn.

maskRgn

A handle to a region acting as a mask for the transfer. 
Discussion

The StdBits function transfers a bit or pixel image between the bitmap or pixel map specified in the srcBits parameter and bitmap of the current graphics port, just as if the CopyBits function were called with the same parameters and with a destination bitmap equal to (* thePort).portBits.

void LocalToGlobal (
   Point * pt

Parameters
pt

A pointer to a point in local coordinates. On return, this point is converted to global coordinates.
Discussion

The LocalToGlobal function converts the given point from the current graphics port’s local coordinate system into the global coordinate system (where the upper-left corner of the main screen has coordinates [0,0]). This global point can then be compared to other global points, or it can be changed into the local coordinates of another graphics port.

Because a rectangle is defined by two points, you can convert a rectangle into global coordinates with two calls to LocalToGlobal. In conjunction with LocalToGlobal, you can use the OffsetRect, OffsetRgn, or OffsetPoly functions to convert a rectangle, region, or polygon into global coordinates.

   const Rect * r,

r

The pointer to the rectangle defining the area to be scrolled.
dh

The horizontal distance to be scrolled.
dv

The vertical distance to be scrolled.
updateRgn

A handle to the region of the window that needs to be updated. 
Discussion

The ScrollRect function shifts pixels that are inside the specified rectangle of the current graphics port. No other pixels or the bits they represent are affected. The pixels are shifted a distance of dh horizontally and dv vertically. The positive directions are to the right and down. The pixels that are shifted out of the specified rectangle are not displayed, and the bits they represent are not saved. It is up to your application to save this data. 

The empty area created by the scrolling is filled with the graphics port’s background pattern, and the update region is changed to this filled area. 

The ScrollRect function doesn’t change the local coordinate system of the graphics port it simply moves the rectangle specified in the r parameter to different coordinates. Notice that ScrollRect doesn’t move the graphics pen or the clipping region. However, because the document has moved, they’re in different positions relative to the document.

By creating an update region for the window, ScrollRect forces an update event. After using ScrollRect, your application should use its own window-updating code to draw into the update region of the window.

Discussion

The background color is the color of the pixels in the bitmap wherever no drawing has taken place. By default the background color of a GrafPort is white.

The BackColor function sets the background color for the current graphics port to the color that you specify in the color parameter. When you draw with the patCopy and srcCopy transfer modes, for example, white pixels are drawn in the color you specify with BackColor.

All nonwhite colors appear as black on black-and-white screens. Before you use BackColor, use the DeviceLoop function to determine the color characteristics of the current screen.

Parameters
r

The rectangle that defines an oval’s boundaries.
startAngle

The angle indicating the start of the arc.
arcAngle

The angle indicating the arc’s extent.
Discussion

Using the pattern, pattern mode, and size of the graphics pen for the current graphics port, the FrameArc function draws an arc of the oval bounded by the rectangle that you specify in the r parameter. Use the startAngle parameter to specify where the arc begins as modulo 360. Use the arcAngle parameter to specify how many degrees the arc covers. Specify whether the angles are in positive or negative degrees a positive angle goes clockwise, while a negative angle goes counterclockwise. Zero degrees is at 12 o’clock high, 90 (or –270) is at 3 o’clock, 180 (or –180) is at 6 o’clock, and 270 (or –90) is at 9 o’clock. Measure other angles relative to the bounding rectangle.

A line from the center of the rectangle through its upper-right corner is at 45, even if the rectangle is not square a line through the lower-right corner is at 135, and so on. 

The arc is as wide as the pen width and as tall as the pen height. The pen location does not change. 
Special Considerations

/*OpenPoly

Begins defining a polygon. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

PolyHandle OpenPoly ();
Return Value

A handle to a new polygon. 
Discussion

The OpenPoly function starts saving lines for processing as a polygon definition. While a polygon is open, all calls to the Line and LineTo functions affect the outline of the polygon. Only the line endpoints affect the polygon definition; the pattern mode, pattern, and size do not affect it. The OpenPoly function calls the HidePen function, so no drawing occurs on the screen while the polygon is open (unless you call the ShowPen function just after calling OpenPoly, or you called ShowPen previously without balancing it by a call to HidePen).

A polygon should consist of a sequence of connected lines. The OpenPoly function stores the definition for a polygon in a Polygon structure. 

When a polygon is open, the current graphics port’s polySave field contains a handle to information related to the polygon definition. If you want to temporarily disable the polygon definition, you can save the current value of this field, set the field to NULL, and later restore the saved value to resume the polygon definition.

Even though the onscreen presentation of a polygon is clipped, the definition of a polygon is not; you can define a polygon anywhere on the coordinate plane.

When you are finished calling the line-drawing functions that define your polygon, use the ClosePoly function. 
Special Considerations

Do not call OpenPoly while a region or another polygon is already open.

Polygons are limited to 64 KB. You can determine the polygon size while it is being formed by calling the Memory Manager function GetHandleSize. 

The OpenPoly function may move or purge memory blocks in the application heap; do not call this function at interrupt time.

/*QDError

Obtains a result code from the last applicable QuickDraw function that you called. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

short QDError ();
Return Value

The error result. On a system with only basic QuickDraw, QDError always returns noErr. 
Discussion

The QDError function is helpful in determining whether insufficient memory caused a drawing operation - particularly those involving regions, polygons, pictures, and images copied with CopyBits - to fail.

Basic QuickDraw uses stack space for work buffers. For complex operations such as depth conversion, dithering, and image resizing, stack space may not be sufficient. QuickDraw attempts to get temporary memory from other parts of the system. If that is still not enough, QDError returns the nsStackErr error. If your application receives this result, reduce the memory required by the operation.

When you structure drawing operations in an open region, the resulting region description may overflow the 64 KB limit. In this case, QDError returns regionTooBigError. Since the resulting region is potentially corrupt, the CloseRgn function returns an empty region if it detects QDError has returned regionTooBigError. A similar error, rgnTooBigErr, occurs when using the BitMapToRegion function to convert a bitmap to a region.

The BitMapToRegion function also generates the pixmapTooDeepErr error if a PixMap structure is supplied that is greater than 1 bit per pixel. You may be able to recover from this problem by coercing your PixMap structure into a 1-bit PixMap structure and calling the BitMapToRegion function again. 
Special Considerations

The QDError function does not report errors returned by basic QuickDraw.

/*OpenCPicture

Begins defining a picture in extended version 2 format. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

PicHandle OpenCPicture (
   const OpenCPicParams * newHeader
);
Parameters
newHeader

An OpenCPicParams structure. 
Return Value

A handle to a new Picture structure. OpenCPicture collects your subsequent drawing commands in this structure. Use this handle when referring to the picture in subsequent functions, such as the DrawPicture function. 
Discussion

When defining a picture, you can use all other QuickDraw drawing functions, with the exception of CopyMask, CopyDeepMask, SeedFill, SeedCFill, CalcMask, and CalcCMask. You can also use the PicComment function to include picture comments in your picture definition.

The OpenCPicture function creates a pictures in the extended version 2 format. This format permits your application to specify resolutions when creating images.

Use the OpenCPicParams structure you pass in the newHeader parameter to specify the horizontal and vertical resolution for the picture, and specify an optimal bounding rectangle for displaying the picture at this resolution. When you later call the DrawPicture function to play back the saved picture, supply a destination rectangle, and DrawPicture scales the picture so that it is completely aligned with the destination rectangle. To display a picture at a resolution other than that at which it was created, compute an appropriate destination rectangle by scaling its width and height by the following factor:

scale factor = destination resolution / source resolution 

For example, if a picture was created at 300 dpi and you want to display it at 75 dpi, then your application should compute the destination rectangle width and height as 1/4 of those of the picture’s bounding rectangle.

The OpenCPicture function calls the HidePen function, so no drawing occurs on the screen while the picture is open (unless you call the ShowPen function just after OpenCPicture, or you called ShowPen previously without balancing it by a call to HidePen).

After defining the picture, close it by using the ClosePicture function. 

After creating the picture, use the GetPictInfo function to gather information about it. The PictInfo structure returned by GetPictInfo returns the picture’s resolution and optimal bounding rectangle. 
Special Considerations

When creating a picture, use the ClosePicture function to finish it before you open the Printing Manager with the PrOpen function. There are two main reasons for this. First, you should allow the printing driver to use as much memory as possible. Second, the Printing Manager creates its own type of graphics port, one that replaces the standard QuickDraw drawing operations stored in the grafProcs field of a CGrafPort or GrafPort structure. To avoid unexpected results when creating a picture, draw into a graphics port created with QuickDraw instead of drawing into a printing port created by the Printing Manager. 

After calling OpenCPicture, be sure to finish your picture definition by calling ClosePicture before you call OpenCPicture again. You cannot nest calls to OpenCPicture.

Always use the ClipRect procedure to specify a clipping region appropriate for your picture before you call OpenCPicture. If you do not use ClipRect to specify a clipping region, OpenCPicture uses the clipping region specified in the current graphics port. If the clipping region is very large (as it is when a graphics port is initialized) and you scale the picture when drawing it, the clipping region can become invalid when DrawPicture scales the clipping region—in which case, your picture will not be drawn.

The OpenCPicture function may move or purge memory; do not call at interrupt time.

/*FramePoly

Draws the outline of a polygon. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

void FramePoly (
   PolyHandle poly
);
Parameters
poly

A handle to the polygon to draw. The OpenPoly function returns this handle when you first create the polygon. 
Discussion

Using the current graphics port’s pen pattern, pattern mode, and size, the FramePoly function plays back the line-drawing commands that define the polygon whose handle you pass in the poly parameter. 

The graphics pen hangs below and to the right of each point on the boundary of the polygon. Thus, the drawn polygon extends beyond the right and bottom edges of the polygon’s bounding rectangle (which is stored in the polyBBox field of the Polygon structure) by the pen width and pen height, respectively. All other graphics operations, such as painting a polygon with the PaintPoly function, occur strictly within the boundary of the polygon.

If a polygon is open and being formed, FramePoly affects the outline of the polygon just as if the line-drawing functions themselves had been called. If a region is open and being formed, the outside outline of the polygon being framed is mathematically added to the region’s boundary.

The result of this function is undefined whenever any horizontal or vertical line through the polygon would intersect the polygon’s outline more than 50 times. 
Special Considerations

The FramePoly function may move or purge memory blocks in the application heap; do not call this function at interrupt time.

/*PortSize

void PortSize (

   short height
);
Parameters
width

The width of the reset port rectangle.
height

The height of the reset port rectangle.
Discussion

The PortSize function is normally called only by the Window Manager. The PortSize function changes the size of the current graphics port’s port rectangle. The upper-left corner of the port rectangle remains at its same location the width and height of the port rectangle are set to the given width and height. In other words, PortSize moves the lower-right corner of the port rectangle to a position relative to the upper-left corner.

The PortSize function doesn’t change the clipping or visible region of the graphics port, nor does it affect the local coordinate system of the graphics port it changes only the width and height of the port rectangle. Remember that all drawing occurs only in the intersection of the boundary rectangle and the port rectangle, after being cropped to the visible region and the clipping region.

void DeviceLoop (
   RgnHandle drawingRgn,

Parameters
drawingRgn

A handle to the region in which you will draw; this drawing region uses coordinates that are local to its graphics port. 
drawingProc

A pointer to your own drawing function. 
userData

Any additional data that you wish to supply to your drawing function.
flags

One or more members of the set of flags defined by the Device Loop Flags data type. if you want to use the default behavior of DeviceLoop, specify an empty set ([]) in this parameter. 
Discussion

The DeviceLoop function searches for graphics devices that intersect your window’s drawing region, and it calls your drawing function for each dissimilar video device it finds. 

Because DeviceLoop provides your drawing function with the pixel depth and other attributes of each video device, your drawing function can optimize its drawing for each video device.

See DeviceLoopDrawingProcPtr for a description of the drawing function you must provide for the drawingProc parameter.

The DeviceLoop function may move or purge memory blocks in the application heap; do not call this function at interrupt time.

Parameters
bm

A pointer to the BitMap structure to set for the current graphics port. Be sure to prepare all fields of the BitMap structure before you call SetPortBits. 
Discussion

You should never need to use this function. This function, created for early versions of QuickDraw, allows you to perform all normal drawing and calculations on a buffer other than the screen—for example, copying a small offscreen image onto the screen with the CopyBits function. However, instead of using SetPortBits, you should use the more powerful offscreen graphics capabilities.

/*CopyMask

Copies a bit or pixel image from one graphics port or offscreen graphics world into another graphics port only where the bits in a mask are set to 1. (Deprecated in Mac OS X v10.4. Use Quartz 2D instead; see Quartz Programming Guide for QuickDraw Developers.)

void CopyMask (
   const BitMap * srcBits,
   const BitMap * maskBits,
   const BitMap * dstBits,
   const Rect * srcRect,
   const Rect * maskRect,
   const Rect * dstRect
);
Parameters
srcBits

The source BitMap structure. 
maskBits

The mask BitMap structure.
dstBits

The destination BitMap structure.
srcRect

The source rectangle.
maskRect

The mask rectangle. This must be the same size as the rectangle passed in the srcRect parameter. The rectangle you pass in this parameter selects the portion of the bitmap or pixel map that you specify in the maskBits parameter to use as the mask.
dstRect

The destination rectangle.
Discussion

The CopyMask function copies the source bitmap or pixel map that you specify in the srcBits parameter to a destination bitmap or pixel map that you specify in the dstBits parameter—but only where the bits of the mask bitmap or pixel map that you specify in the maskBits parameter are set to 1. When copying images between color graphics ports, you must coerce each CGrafPort structure to a GrafPort structure, dereference the portBits fields of each, and then pass these “bitmaps” in the srcBits and dstBits parameters. If your application copies a pixel image from a color graphics port called MyColorPort, for example, you could specify (* GrafPtr(MyColorPort)).portBits in the srcBits parameter. 

Using the srcRect and dstRect parameters, you can specify identically or differently sized source and destination rectangles; for differently sized rectangles, CopyMask scales the source image to fit the destination. When you specify rectangles in the srcRect and dstRect parameters, use the local coordinate systems of, respectively, the source and destination graphics ports.

If you specify pixel maps to CopyMask, they may range from 1 to 32 pixels in depth. The pixel depth of the mask that you specify in the maskBits parameter is applied as a filter between the source and destination pixel maps that you specify in the srcBits and dstBits parameters. A black mask pixel value means that the copy operation is to take the source pixel a white value means that the copy operation is to take the destination pixel. Intermediate values specify a weighted average, which is calculated on a color component basis. For each pixel’s color component value, the calculation is

(1 – mask) x source + (mask) x destination

Thus high mask values for a pixel’s color component reduce that component’s contribution from the source PixMap structure. 

Use the bitmap returned by CalcMask as the mask in order to implement a mask copy similar to that performed by the MacPaint lasso tool. In the same way, you can use the pixel map returned by the CalcCMask function.

The CopyDeepMask function combines the functions of the CopyMask and CopyBits functions. 
Special Considerations

Calls to CopyMask are not recorded in pictures and do not print.

See the list of special considerations for CopyBits; these considerations also apply to CopyMask.

The CopyMask function may move or purge memory blocks in the application heap; do not call this function at interrupt time.

/*EraseOval

void EraseOval (

Parameters

The rectangle that defines the oval’s boundary.
Discussion

Using the background pattern for the current graphics port and the patCopy pattern mode, the EraseOval function draws the interior of an oval just inside the bounding rectangle that you specify in the r parameter. This effectively erases the oval bounded by the specified rectangle.
