<p>InterpretImageProperties() replaces any embedded formatting characters with the appropriate image property and returns the interpreted text.</p>

<p>This searches for and replaces \n \r \          replaced by newline, return, and percent resp. &amp;lt; &amp;gt; &amp;amp;   replaced by '&lt;', '&gt;', '&amp;' resp. replaced by percent</p>

[name]       where 'name' is a specifically known attribute, calculated value, or a per-image property string name, or a per-image 'artifact' (as generated from a global option). It may contain ':' as long as the prefix is not special.</p>

<p>Single letter  substitutions will only happen if the character before the percent is NOT a number. But braced substitutions will always be performed. This prevents the typical usage of percent in a interpreted geometry argument from being substituted when the percent is a geometry flag.</p>

<p>If 'glob-expresions' ('*' or '?' characters) is used for 'name' it may be used as a search pattern to print multiple lines of "name=value\n" pairs of the associacted set of properities.</p>
