Created attachment 40757 [details] [review] Create cairo image surface in case of a8 Qt does not support rendering into A8 format, so cairo-qt in that case just fail ............. QPainter::begin: Cannot paint on an image with the QImage::Format_Indexed8 format Segmentation fault QImage does not support painting on A8 surface, and not possible create qpainter. ............. https://bugzilla.mozilla.org/show_bug.cgi?id=602171 http://doc.qt.nokia.com/4.7/qimage.html#Format-enum Note: Drawing into a QImage with QImage::Format_Indexed8 is not supported.
Anyone happen to know if this is still an issue with Qt? It's been 5 years since this issue was filed so perhaps this is no longer necessary?
