CentOS - Dec 2009 - Image conversion with ImageMagick doesn't work on CentOS, but it works fine on Debian Lenny.

I recently came across the need to convert jpg images with IM, did a
standard install of "yum -y install ImageMagick" and found that
images converted with CentOS's base port of IM would actually corrupt the
images, yet using the same (albiet different version, different distro)
software
didn't corrupt the images at all.

By corrupted, I mean, the bottom portion of the image under *some*
webservers looked completely wrong, and had strange checkering of the image
in stripes across the bottom.

At the time I had this problem, I took the issue to IM's forum, to no
avail.  I ended up just using it on a Debian machine instead.

I use convert and mogrify on a reasonably regular basis for various
tasks and haven't noticed any problems here.

Is there anything "special" about your images?  You are converting
them
from jpg to.. what format?

Which version of CentOS?  I use convert all of the time with CentOS 4.8,
using ImageMagick 6.0.7.1-20.el4 without any problems:

sauron.deepsoft.com% rpm -q ImageMagick
ImageMagick-6.0.7.1-20.el4

*Exactly* which version of CentOS, ImageMagick?  i386 or x86_64?
