Hi all, reading through some discussion which steps on "default alpha for layers?" and "erase to alpha or to white?" questions, there's one solution i haven't seen yet:
assign a background color to GIMP images. Not a layer, just a single color. This way, the eraser can always work on alpha, and all layers consistently can have an alpha channel. This also sanitizes Export a bit, the canonical example being PNG export: "flatten image or merge visible layers?" really asks wether to fill transparency with a background color. Now this color is a property of the image, so the question has been answered already. Import is also hassle-free: if the file format supports transparency, the bg color is transparent, otherwise GIMP's default bg color. So a cycle of export and re-import doesn't change the image. I tried to attach a trivial mockup of the layer dialog, reserving half a layer height for the background color, but i'm shure it won't hurt if this got lost in transmission ;) greetings, peter *) http://bugzilla.gnome.org/show_bug.cgi?id=569330 http://bugzilla.gnome.org/show_bug.cgi?id=486902
