I don't think that appendBezierPathWithGlyphs: will help you on your specific problem. (Although the method itself should work) That way you would get a path with all the outlines of the string, again you could only transform the whole of it, but as I understand you, you would like to transform each single glyph. In the cairo mailing list this is a subject that comes up from time to time. The last time was November last year and the subject was " render text along path" it should be easy to google for that. Here are some of the hints that came up at that discussion. Pycairo comes with the example examples/warpedtext.py which draws text along a path. http://svn.gnome.org/viewvc/pango/trunk/examples/cairotwisted.c?view=markup http://www.flickr.com/photos/behdad/3058628981/sizes/o/ Hope this helps Fred _______________________________________________ Discuss-gnustep mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnustep
