![]() ![]() I know that Michael Davies touched on them briefly in a YouTube video, but I could not replicate his results. If someone out there knows how these work, please let me know. I did work it out for Color Erase and Erase, but these have me stumped. These are obviously opposites in some sense, but there is no documentation of them right now, and I have not succeeded in working out what is going on with them. But with Layer Mode set to Erase, painting with the White color actually makes the top layer transparent where you paint, and reveals the layer below it. In normal Layer Mask situations, painting the Layer mask with White would make the layer opaque, thus hiding anything underneath it. Then make your Foreground color White, and select the Paintbrush tool. Make sure that you select White (Full Opacity), and do not leave a check mark in the Invert Mask box. ![]() To see how this works, select the Top layer, and add a Layer Mask using button on the bottom of the Layers window. Recall that Layer Masks work by creating transparency, and so does this Layer Mode, and it is like a double-negative. This is an interesting effect, though you might not need to use it often.Īnother interesting feature is that this can reverse a Layer Mask effect. GIMP image with Symbols erased and gradient on the bottom I then moved the borders of the text box to just touch the symbols, and centered the box using the Alignment tools (Tools –>Transform Tools–>Align, or click on the Move tool and select Alignment). I then created a New Layer filled with transparency, selected my text tool, drew a text box, and typed some letters (A,B,C,D,E) which showed up as symbols. This made my new font a selection, so I clicked on it to select it. I right-clicked on a font at random, then selected Rescan Font List. It has some interesting symbols, so I downloaded the zip file containing the font, moved it to my ~/.fonts directory (making it available to any application on my Kubuntu box), and then clicked the Fonts tab on the Upper Right (where you see your tabs for Brushes, Patterns, Gradients, and so on). The font I chose was in the Dingbats section and is called FivefoldOrnamentsEtc. I can use them anywhere without worrying about royalty issues. This license is considered free by the Free Software Foundation, which is a pretty good credential, so when I go looking for fonts I look for OFL-licensed fonts by preference. I went to Font Library, which has lots of Open Font Licensed fonts, as we discussed previously in Free, Public Domain and Creative Commons Assets. To illustrate this process I decided to try adding a new font since we haven’t done that recently. This could create something interesting, though anything I have been able to think of could be done in other ways, and probably more simply. Then using the Erase mode would invert that on the Bottom layer, where the opaque shape would become transparent. To be of any use (I would think) you would need to have the Top layer contain some kind of shape on a transparent background. If the two layers are the same size, using Erase mode on the Top layer would simply make the bottom layer completely transparent by erasing all of the pixels. ![]() EraseĮrase will erase from the bottom layer any pixel for which there is a pixel in the top layer. There are three more Normal Layer Modes to consider, Erase, Merge, and Split. Done using GIMP 2.10.20 on Kubuntu Linux 18.04 LTS
