Description Matthias Welwarsky 2009-03-12 23:26:27 UTC 
Version:            (using KDE 4.2.1)
OS:                Linux
Installed from:    Ubuntu Packages

libraw 0.6.16 imported into kdegraphics with svn revision 936988 breaks RW2 file development, the decoded image has false colors in highlight regions that look like results of integer overflow.

Comment 2 Alex Tutubalin 2009-03-13 06:52:41 UTC 
At least, there is no LibRaw 0.6.16 :)

Lates version in 0.6 branch is 0.6.14. I think, Gilles has mistyped in announce.
Comment 3 Alex Tutubalin 2009-03-13 06:54:16 UTC 
Also, I need sample RW2 file to play with.
Comment 4 Matthias Welwarsky 2009-03-13 08:31:13 UTC 
Whoops, sorry, my bad.
I misread the svn log, I thought it was 0.6.16
But the svn revision is correct. If I revert it, all is fine again.

Alex, where can I upload a sample? Can bugzilla handle such big attachements?
Comment 5 Alex Tutubalin 2009-03-13 09:04:57 UTC 
Unfortunately, I've no ftp server with open upload.

You can use some of 'file sharing' services, such as rapidshare or megaupload.com
Just send me link to personal mail (or post it here)
Comment 6 Alex Tutubalin 2009-03-13 16:58:55 UTC 
I was able to reproduce the problem on my samples. You don't need to send me yours :)

Working on fix now.
Comment 7 Alex Tutubalin 2009-03-13 19:55:08 UTC 
This bug fixed in LibRaw 0.6.15.
