I'm trying to Print an images "Palette size" by embedding special format characters. The IM special characters page (http://www.imagemagick.org/script/escape.php) doesn't list a special character for palette size. I tried several similar special characters, like %q and %z, and could not find the right one for palette size. Is there a special format character that can print the palette size? Thanks

Take a look here:
http://www.imagemagick.org/Usage/basics/#ping

trying using -identify -ping on the image to find the pallate size.

this works:

convert rose: -type palette rose_palette.gif

colormap=`identify -verbose rose_palette.gif | sed -n 's/^.*Colormap:[ ]*\(.*\)$/\1/p'`
echo $colormap
