I have now surveyed example 28 results for all the other non-Hershey devices that are accessible to me. (The only non-Hershey one I have not been able to check is aqt so I hope someone with access to Mac OS X will look carefully at that one and compare it with the good results from either the xwin, qt, or cairo devices.) Of those devices I surveyed, most are fine i.e, they give the same results as the xwin and cairo (and qt) devices. The svn trunk cairo device driver uses pls->alt_unicode = 1; which means it uses an alternative "new" software chain for handling text. I also locally tried pls->alt_unicode = 0; and that gave good example 28 results as well. There are a few exceptions to these good results. * ps and psttf both have text offset issues for pages 2, 3 and 4 (bug 2909788 which I have assigned to Andrew). * The svg and wxwidgets (wxGC) devices both have the same issue with page 1 (the rotation texts form a circle rather than the ellipse you expect due to 3D perspective and which you get with xwin and the other devices). I will take responsibility for dealing with this 3D text bug for the software chain used for the svg device. Once I find the fix for that, it should also solve the wxwidgets (wxGC) issue if the bug is in common code used by both. Alan __________________________ Alan W.
