I don't know if it can solve your issue, but if you alter surface data by accessing directly the memory buffer, you have to use cairo_surface_mark_dirty. If you forget this call, cairo may discard what you have done. Emmanuel. -- cairo mailing list [email protected] http://lists.cairographics.org/mailman/listinfo/cairo
