A search seems to indicate that all other backends just look for whether it is FAST/NEAREST or not. So they do not care about bilinear verses good. I suspect some backends, in particular the drm ones, are not doing the filtering, and need a similar fallback. I am not clear however. Lots of other backends I think are doing "good" filtering even if bilinear is selected, this is probably ok. >> - A CAIRO_RENDER option maybe should be added in case pixman ever >> supports GOOD/BEST. It is probably best to add the config option or flag now. I think pixman will support this some day, though there certainly was resistance to my first attempt to send a patch for it. > Should the above notes be taken care of before this is merged? I will try to add the flags indicating if the filters work and send another patch. -- cairo mailing list [email protected] http://lists.cairographics.org/mailman/listinfo/cairo
