Transparent should be opaque, opaque should be transparent, almost transparent should be almost opaque, etc. Quickest way is to right click on the layer and choose Add Layer Mask. From there choose Transfer layer's alpha channel. Then select the newly created mask and do Invert from the Colors menu. You can then apply the mask if you want. -- Ville Pätsi ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list

Re: [Gimp-user] Invert alpha channel
Layer - Transparency - Alpha to Selection. Save as channel. Apply as layer mask. Invert. Does that help?

Choose Colors - Components - Decompose from the menu and set Color model to RGBA. 2. A new image is opened with all color channels (including alpha channel) decomposed as single layers. 3. Select the layer alpha and choose Colors - Invert from the menu. 4. Choose Colors - Components - Compose from the menu, set Color model to RGBA and make sure the layers are correctly mapped to the channels (should be given if you did not reorder the layers) Regards Eduard ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list
