* Duplicate the layer. * Desaturate the duplicate using the "Average" method. * Add layermask to the duplicate using the "Initialize to: Grayscale Copy of Layer" option. * Bucket fill the duplicate layer with white. * Run "Colors->Threshold" on the layermask, setting the value appropriately. * Bucket fill your original layer with black. _______________________________________________ Gimp-user mailing list [email protected] https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
