This is all starting to make a great deal more sense to me. Thanks for the all of the helpful explanations everyone. Perhaps one more question: given a cairo surface created via cairo_surface_create_similar, is it possible to go though the X process of rasterization without displaying? So that the process of cairo_paint() simply hands off the already rasterized pixmap to X? Perhaps this is the purpose of cairo_flush_surface()? -- cairo mailing list [email protected] https://lists.cairographics.org/mailman/listinfo/cairo
