The important features are: +<ul> +<li> certain "structured comments" are required; important ones are + the identification of the file type, and information about the + "bounding box" of the figure (i.e., the minimum rectangle + enclosing it); +<li> some commands are forbidden - for example, a <code>showpage</code> + command will cause the image to disappear, in most TeX-output + environments; and +<li> "preview information" is permitted, for the benefit of things + such as word processors that don't have the ability to draw + PostScript in their own right - this preview information may be in + any one of a number of system-specific formats, and any viewing + program may choose to ignore it. +</ul> +A PostScript figure that conforms to these rules is said to be in +"Encapsulated PostScript" format. Most (La)TeX packages for +including PostScript are structured to use Encapsulated PostScript; +which of course leads to much hilarity as exasperated (La)TeX users +struggle to cope with the output of drawing software whose authors +don't know the rules. +<p><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=eps">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=eps</a> +</body> |
