characters:</p>
<pre class="text">
%b file size of image read in
%c comment meta-data property
%d directory component of path
%e filename extension or suffix
%f filename (including suffix)
%g layer canvas page geometry ( = %Wx%H%X%Y )
%h current image height in pixels
%i image filename (note: becomes output filename for "info:")
%k CALCULATED: number of unique colors
%l label meta-data property
%m image file format (file magic)
%n number of images in current image sequence
%o output filename (used for delegates)
%p index of image in current image list
%q quantum depth (compile-time constant)
%r image class and colorspace
%s scene number (from input unless re-assigned)
%t filename without directory or extension (suffix)
%u unique temporary filename (used for delegates)
%w current width in pixels
%x x resolution (density)
%y y resolution (density)
%z image depth (as read in unless modified, image save depth)
%A image transparency channel enabled (true/false)
%C image compression type
%D image GIF dispose method
%G image size ( = %wx%h )
%H page (canvas) height
%M Magick filename (original file exactly as given, including read mods)
%O page (canvas) offset ( = %X%Y )
%P page (canvas) size ( = %Wx%H )
%Q image compression quality ( 0 = default )
%S ?? scenes ??
%T image time delay (in centi-seconds)
%W page (canvas) width
%X page (canvas) x offset (including sign)
%Y page (canvas) y offset (including sign)

%% a percent sign
\n newline
\r carriage return
&lt; less-than character.
&gt; greater-than character.
&amp; ampersand character.
