Hi Daniel
Actually my description of the bug I think it was not too accurate.
The problem is gm display begins to hang. If I open more images in gm
and 'Next' the image, it works. As soon I let show a Histogram of an
image however, gm hangs, and going to a next image is not possible.
Does this makes any sense? Is there more information you need?
It makes sense to me. I am not sure which GraphicsMagick version this
bug is reported against but the fix is likely to add an '&' character
to the end of certain delegates.mgk file entries so that the shell
command runs in the background. Current releases have this. For
example:
<delegate encode="show" stealth="True" command='"@GMDelegate@" display
-immutable -delay 0 -window_group %g -title "%l of %f" "tmp:%o" &' />
Without the ampersand, the foreground program (display) blocks waiting
for the subordinate program to exit.
