composite -stereo no longer makes anaglyph

Post by tksharpless » 2017-05-24T18:51:57-07:00

In IM 6 the (Windows) command line
composite -stereo 0 %~2 %~1 %out%
made a red/cyan color anaglyph, and
composite -stereo 0 %~2 -colorspace gray %~1 -colorspace gray %out%
made a grayscale one.

But in IM 7 the same lines (prefixed with magick) make all-red images.
Did I miss a documentation update, or is something broken?

Glad you are still distributing IM 6, as I have a bunch of production scripts that depend on it.

Please post your commands with actual filenames and provide the files so we can test properly your example. It is possible that there is a bug in IM 7. Also please identify your IM version. There was a relatively recent update that fixed other problems that showed only red.

It works for me with ImageMagick 7.0.5-5 Q16 x64.
