Segmentation fault with display

Post by naoliv »

Hi!

Trying to reproduce the bug report from https://bugs.edge.launchpad.net/ubuntu/ ... +bug/43323 I am getting a segmentation fault with ImageMagick 6.4.3-4, when running display 'vid:*.jpg' inside a dir with jpeg files:

Code: Select all

Starting program: /usr/bin/display 'vid:*.jpg'

The program is running.  Exit anyway? (y or n)
(BTW, is it right to call display 'vid:*.jpg' like the user is doing?)

Thank you!

Thanks for the problem report. We have patch for the problem you reported in the Subversion trunk (available sometime tomorrow) and it will be available in the next point release.

To fix the problem in your source distribution, edit coders/vid.c and change 'SetImageProgress(image,' to 'SetImageProgress(images,'.

I have an IM Example doing just that, but you have to quote the '*' so IM expands it.
http://www.imagemagick.org/Usage/montage/#vid
It is a special 'montage' input method.
