#590 Pixel cache dimensions incompatible with image dimensions

[Matthias Kiefer]

GraphicsMagick 1.3.31 fails to convert the attached pict-file with the error message:

$ gm convert MARBLES.PCT MARBLES.JPG
gm convert: Pixel cache dimensions incompatible with image dimensions (MARBLES.JPG).

I can reproduce the problem on a Mac (Sierra, 10.12.6) with graphicsmagick installed via homebrew:

@bfriesen: Can you reproduce this problem? Do you need more information?

[Bob Friesenhahn]

I will work on this issue as available time permits.

[Bob Friesenhahn]

I have encountered this sample file before. As far as I am aware, GraphicsMagick has never displayed this image correctly. Instead I get an all black image. Modern ImageMagick seems to display it properly.

[Bob Friesenhahn]

This problem is fixed now. The fix is provided by Mercurial changeset 16208:873fe3a5a171. Thanks for the report!
