Dear Experts, I am a developer of GrADS, a visualization tool for meteorological data. GrADS uses X11 for its interactive display window, but it also has a batch mode, so you can create graphics without the use of X. We have developed an interface for Cairo to do the rendering, not only to the X window, but also to create png, ps, eps, pdf, and svg output. The problem I am having is with the X rendering when using XQuartz. Everything looks right when I use the old (deprecated) X11 application on my Mac, but if I use XQuartz, I get an incomplete rendering, illustrated by two screen shots (links are given below.) The graphical elements are very basic, these plots contain nothing but line segments and filled rectangles. http://iges.org/jma/x11.png http://iges.org/jma/xquartz.png The batch-mode renderings by Cairo are correct, and the non-Cairo version of GrADS does not exhibit the problem with the X window display, so I am pretty sure that Cairo and XQuartz are not playing well together. I am running Mac OS X 10.7.5. When running the old X11 application, the version information in the "About X11" window says: XQuartz 2.6.5 (xorg-server 1.10.6). When running XQuartz, the version numbers are more recent: XQuartz 2.7.4 (xorg-server 1.13.0). The Cairo version is 1.12.8. I searched through my 2-yr archive of forum emails and found nothing related to rendering problems with XQuartz. Any suggestions or ideas about what might be going wrong would be most welcome. --Jennifer -- Jennifer M.
