![]() ![]() MyPaintĪs you might have guessed, MyPaint is the source of the MyPaint brushes in GIMP that I mentioned earlier. There are other drawing apps that can work better than drawing in GIMP. The Fill Path options don’t let you apply paint tools, so it might be better to fill any shapes by hand if you want to use MyPaint brushes for drawing. Once you’re satisfied with the shape of your path, simply click the Stroke Path button and GIMP will allow you to choose from the same set of options: to apply a solid color, a pattern, or a paint tool along with the shape of the path. The Tool Options panel shows the Paths tool You could also use selections created by the Fuzzy Select tool (Magic Wand) or any of the other selection tools, but only if you’re drawing on an image that has something in the background for them to work on. Selections are best used for drawing the simple shapes that you can make using the Rectangle Select and Elliptical Select tools. Selections are quick and easy, but using paths allows you to create more flowing, freeform shapes with relative ease. To get started, create your shape template using one of the selection tools or the Paths tool. The stroke system allows you to create a selection or a path and then have GIMP trace the outline with a solid color, a pattern, or even one of the many brush-based tools such as the MyPaint brush. If freehand drawing isn’t your style (or within your ability, like yours truly), you can use a different method to draw in GIMP: strokes. If you want a more detailed explanation of the MyPaint system, check out my article on how to paint in GIMP. There are a huge number of brushes that recreate all kinds of drawing media, from pencils to charcoal to pastels, and even blending tools. The MyPaint brush uses the open-source MyPaint library created by the app of the same name, but it’s not just for painting. You can use the Paintbrush tool, the Pencil tool, and the Ink tool, but the really impressive visuals come from using the MyPaint brush, which is stacked in the same section as the other three. Once that’s out of the way, the only secret is to learn to use the various brushes. Your tablet might not work instantly with GIMP, so I’ve prepared a different guide on how to use pressure sensitivity in GIMP. You don’t need to spend a huge amount of money on a fancy one since even a small cheap drawing tablet will give you better results than trying to do serious brushwork with a mouse. If you’re serious about digital sketching, drawing, or painting, I strongly recommend that you buy yourself a graphics tablet.Ī drawing tablet transforms the whole process of interacting with GIMP, and they usually come with a pressure-sensitive stylus and handy shortcut buttons. If you want to add the very same outline to all shapes, once the background has been removed you can use the procedure above one the initial image to add the outline to all the shapes in one go.This is certainly the simplest method for drawing in GIMP, although it can be hard to do with a mouse. Edit>Stroke path and give a width double of what you want.If you want the outline completely inside the shape:.If you want the outline to straddle the edge of the shape, use Edit>Stroke path in "line" mode.Select>To path (makes a path from the selection).Layer>Transparency>Alpha to selection (this create a selection from the shape).To add an outline, in each shape image obtained: ![]() Then do a rectangular selection around the shapes and copy/paste each to new files (typically, Edit>Copy and File>Create from clipboard or Edit>Paste as new image). You should end up with your shapes cleanly cut out. Color>Color to Alpha and remove the white.Increase the threshold just to include background irregularities such as JPEG artefacts. Select the background with the fuzzy selector and a low threshold.Layer>Transparency>Add alpha channel (if there is not one already).Various Edge-Detect filters seem to make out the shapes, but then they mangle the colors on them. How can I do that?Ī simple answer - use a paintbrush and trace the line again - isn't satisfying because my hand won't repeat exact same shapes, so the border will be jaggy.Ī border tool isn't adequate because it creates a simple-minded rectangular border, while I want a free-form shape one. I'd like to create a border around each shape that is exact shape of my freeform selection. These output shapes will be placed on another picture, quite colorful, and if these files are created like this, they are visible very poorly due to colors meshing. So far the solution is easy: use Free Select Tool on each shape, Copy, create a new file, in Advanced Options select "Fill with Transparency", Paste, Image -> Autocrop Image. I want to create several other files, each containing one shape from the original image, placed on the transparent background. I've got an image of several irregular shapes on white background. ![]()
