I'm a big fan of ImageMagick, so thanks for sharing this cool work.
I used montage to stitch 3 images together. The input images all had a
depth of 8, but the resulting image from montage had a depth of 16. I
have some questions.
1. Should montage output an image with the same depth as the input images?
2. Is this is effect of the quantum size?
3. Can I determine the quantum size from a command line utility?
montage -geometry 640x480 -tile 2x2 -frame 1 \
case1/t.ppm case3/t.ppm case7/t.ppm m.ppm
% head -3 case1/t.ppm case3/t.ppm case7/t.ppm m.ppm
==> case1/t.ppm <==
P6
700 509
255
==> case3/t.ppm <==
P6
700 509
255
==> case7/t.ppm <==
P6
700 509
255
==> m.ppm <==
P6
1284 964

% montage --version

This was on Suse 9.3.
==================================================================
It was extremely confusing to me to have montage output a 16 bit image
when I fed it only 8 bit ones.
Once I determined that this was the case I was able to add "-depth 8" to
the command line and get 8 bit images again.
Thanks,
James
