Appendix F: RealPix Tag Summary

This appendix serves as a quick reference for RealPix markup. For complete information on RealPix, see Chapter 7. The section "Conventions Used in this Guide" explains the typographical conventions used in this appendix. In the following tables, an asterisk (*) indicates a required attribute.

<imfl>...</imfl>

The RealPix markup starts with <imfl> and ends with </imfl>. All RealPix markup must occur between these tags. For more information, see "Structure of a RealPix File".

<head/>

The <head/> tag comes just after the opening <imfl> tag, defining overall presentation settings, such as the streaming bit rate and the duration. Unlike the <head> tags in RealText and SMIL, the RealPix <head/> tag closes with a slash, and does not use a corresponding end tag. See "Setting Slideshow Characteristics" for more on the <head/> tag.
