Most likely they could do the completion/inpainting operations more efficiently. However my interest is more in the matting operators, and subsequently application of them. I was mostly interested in inpainting as a target application of matting. However, it's excellent note that it is less attractive to target this action given resynthesizer and GMIC. - Danny _______________________________________________ Gegl-developer mailing list Gegl-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gegl-developer
