These two (http://bugs.debian.org/389604 and http://bugs.debian.org/349200) bugs on Debian are related about memory usage with ImageMagick.
The first one is about display using too much memory to display images.
Using this image, for example: http://naoliv.googlepages.com/image.png, with 1.7 MB of size.
Doing a simple "display image.png" I see it using 248 MB of RAM here, while when using feh, it uses only 53 MB.
The second problem (bug 349200) is also related. The user is using montage with some JPEG images (summing 140 MB on his first test and 188 MB on his last one).
Memory usage explodes when he does this:
Code: Select all
montage -label %f -background '#fff' -geometry +4+4 -resize 10% *-*.jpg index.jpg
