Infinite loop

[double]

Hello,

Identifing a MIFF file results in an infinite loop. The steps to
reproduce this issue:

Code: Select all

wget http://doppelbauer.name/infinite.gif
convert infinite.gif -coalesce -format MIFF infinite.miff
identify infinite.miff

ImageMagick 6.6.5-10 2010-11-22

Thanks a lot

We have a patch for the problem you reported. Look for it in ImageMagick 6.6.9-5 Beta by sometime tomorrow. Thanks.

Code: Select all

wget http://doppelbauer.name/infinite.gif
convert infinite.gif -coalesce -format MIFF infinite.miff
identify infinite.miff

Aside from the bug and the patch! the -format MIFF in the above does nothing!

It makes sense for "mogrify" (as a image file format changer), but not for "convert" which uses -format for a different purpose. (and yes that can be a little confusing).
