Well, since you asked for it ;) here's some comments: /* Initialize the pixmap with a full empty transparent rectangle */ cairo_set_source_rgba (cr, 0.0, 0.0, 0.0, 0.0); cairo_set_operator (cr, CAIRO_OPERATOR_SOURCE); There's CAIRO_OPERATOR_CLEAR, is there particular reason for not using it? Conceptually it could even be faster than source op since it simply ignores the source but I guess it depends on what it actually is reduced to (for example memset vs memcpy). Also, you could use cairo_create_similar() to create cairo surfaces to hold the image data instead of creating a GdkPixmaps, it's designed to do what you want with less code what there is now. -- Kalle Vahlman, [EMAIL PROTECTED] Powered by http://movial.fi Interesting stuff at http://syslog.movial.fi _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
