For what it's worth, the table of equivalences should be something like # ORA comp-op name => new (blend-mode, alpha-compositing) svg:src-over => (normal, source-over) svg:plus => (normal, lighter) svg:multiply => (multiply, source-over) svg:screen => (screen, source-over) svg:overlay => (overlay, source-over) svg:darken => (darken, source-over) svg:lighten => (lighten, source-over) svg:color-dodge => (color-dodge, source-over) svg:color-burn => (color-burn, source-over) svg:hard-light => (hard-light, source-over) svg:soft-light => (soft-light, source-over) svg:difference => (difference, source-over) svg:color => (color, source-over) svg:luminosity => (luminosity, source-over) svg:hue => (hue, source-over) svg:saturation => (saturation, source-over) I think that's right. -- Andrew Chadwick _______________________________________________ CREATE mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/create
