[SOLVED] gray50 pattern is turquoise or red

[NicolasRobidoux]

Code: Select all

magick -size 10x10 pattern:gray50 checks_10.gif

produces a turquoise on white checkerboard, instead of a black on white checkerboard.

P.S. There was a typo above: I originally had black50 instead of gray50.

(I'll try to install the latest and compile with "plain" flags soon.)

Still turquoise with

Version: ImageMagick 7.0.0-0 2012-04-03 Q16 http://www.imagemagick.org

based on the current 7.0.0 alpha, with my funky configure flags.

Now, I'll configure "plain".

Give us a fews days and we will have a patch. Thanks.

FYI:
This morning's svn:
magick -size 10x10 pattern:black50 checks_10.gif
magick: unrecognized image format `black50' @ error/pattern.c/ReadPATTERNImage/980.
(I understand IM is going through huge changes. NNTR)

[magick]

Try gray50 instead of black50.

[NicolasRobidoux]

I suck.

This appears to be broken again:

Code: Select all

magick -size 10x10 pattern:gray50 checks10.png
magick -size 10x10 pattern:gray50 checks10.gif

produce black on red checkerboards.
Today's svn.

We can reproduce the problem you posted and have a patch. Look for it in the Subversion trunk and ImageMagick-7.0.0-0 Alpha by sometime tomorrow. Thanks.
