2000-03-26 Michael Natterer <mitch@gimp.org> * app/gimage_mask.[ch] (gimage_mask_extract): add an "add_alpha" parameter to allow selected regions to be extracted without having an alpha channel added. * app/global_edit.c: pass add_alpha = TRUE. * app/transform_core.[ch]: made the transform core work on non-layer drawables even if no selection is present. Fixes #7485 and #7555. - transform_core_cut(): extract the mask without alpha if operating on a non-layer without having a selection. - transform_core_paste(): return a boolean indicating success instead of a layer and handle channels correctly. - transform_core_do(): if the "floating_tiles" passed to the function are from an un-floated non-layer, treat the whole non-layer as alpha channel and never enter the loop which transforms the (not present) color channels. Also clip the result to ensure that the channel never grows larger then the image. * app/tools_cmds.c * tools/pdbgen/pdb/tools.pdb: transform_core_paste() returns a gboolean now.
