Why are you using the ADD operator ? <div class="gmail_quote">On Wed, Jan 6, 2010 at 5:14 PM, Tim Corio <<a href="mailto:tcorio@rochester.rr.com">tcorio@rochester.rr.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Joonas, I built this very same program on a different machine and the original symptom went away. I don't think the library versions have changed because I'm still including from the same directory names. Now, it no longer crashes, but the resulting image is garbled. It may be a very skewed copy of the original. If each line was skewed by one pixel the image would be recognizable, but at a 45 degree tilt. In this case the image is unrecognizable, but the mix of pixel colors look about right. Any help on this new symptom is appreciated. Thanks, Tim <div><div></div><div class="h5"> On Sun, 2010-01-03 at 15:37 +0200, M Joonas Pihlaja wrote: > Hi Tim, > > I ran your program on my 64 bit Debian Linux Etch machine using > gtk+-2.0 version 2.12.12, whatever aged X.org server comes with Debian > stable, and various combinations of cairo 1.6.4, 1.8.x, and the > current cairo master, but couldn't trigger the assertion you saw.
