Description Alex Cherepanov 2010-07-18 15:37:11 UTC 
Many files display the following warning:
**** Unknown color space method in JPX stream.
**** Warning: image has no /ColorSpace key; assuming /DeviceRGB.
Some images in the files, presumably affected by the warning,
are rendered incorrectly.

Update to reflect customer status and ID.
Comment 2 Alex Cherepanov 2010-07-23 20:15:14 UTC 
"Unknown color space method" is an unrestricted ICC-based color space but
setting it now will cause PS errors (instead of wrong images) because
it's not clear yet what to do with alpha channels.
Comment 3 Henry Stiles 2010-07-27 17:12:21 UTC 
Eventually we want to move to openjpeg but assigning to Michael since he has a workaround in Jasper that might address this issue.

patch

Don't include opacity channels in the number-of-components count.
Recognize general ICC profile (type 3) and construct a corresponding
ICC-based color space.

Other problems are caused by mis-interpretation of the opacity
layer and tracked by the bug 691489.
