Re: composite -stereo no longer makes anaglyph

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

composite -stereo no longer makes anaglyph

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,...

Re: can't read ACR 7.1 HDR dng

I think it has to do with the latest version of ACR (7.1) -- exporting from LR with the option of compatibility with an earlier version gives a file that dcraw can read.

Re: Gray anaglyph

Ideally, the -stereo operator should automatically convert a single channel image to 3 channel.

Re: Gray anaglyph

The images are rgb to begin with. But gray anaglyph is usually better for checking stereo alignment.

Re: Gray anaglyph

Thanks much. Yes,
composite -stereo 0 rgt.jpg -colorspace gray lft.jpg -colorspace gray anagg.jpg

Gray anaglyph

QImageReader can't read IM jpegs

Converted a bunch of tiffs to jpeg with mogrify -format jpg (current IM version). When I try to read them with a Qt QImageReader it reports "unable to read image data". Several other apps including Photoshop read those files OK, so this is not really an IM bug, but a Qt one. I just thought you might...
