Paint in black for full transparency, and white for full opacity. However, if the layer mask is not much wrong, you can also edit it directly by clicking on the layer mask thumbnail in the layers panel, and edit the mask using the Paint Brush tool to paint on the mask. It would be great if GIMP had live vector masks you could edit (like Photoshop), but it doesn't have this feature yet. In the case of Photoshop, deselect can be toggled by pressing Crtl + D on Windows and CMD + D on Mac. Left click to start a path and then add more lines by moving and. Some of the most commonly used selection tools in GIMP include the Rectangle Selection Tool, Ellipse Select Tool, Free Selection Tool (Lasso Tool), Fuzzy Selection Tool (Magic Wand Tool), Select by Color Tool, and Scissors Selection Tool. These tools allow you to select specific parts of an image. The moral to this story is to make sure your path is right before you turn it into a selection and apply the layer mask. Select the Paths Tool from the tool icon area or you can find it at Tools Paths. GIMP offers a variety of selection tools to choose from. Then after you have edited the path, turn it into a selection again, and add another layer mask. When you want to deselect everything that was previously selected, the shortcut Ctrl + D won’t work in GIMP. Delete the layer mask by right clicking it in the layers panel and choose Delete Layer Mask. Deselect the selection by pressing Shift+CTRL+A (Select None). They’re more or less the same when it comes to the settings available in the Tools Options panel, except the Pencil tool draws with sharp jagged edges no matter what brush hardness setting you use because it specifically doesn’t allow antialiasing (presumably in a misguided attempt to look more like a pencil).You'll not only need to select the path in the paths dialog, and click on it to make it visible, and edit with the Paths Tool, as per instructions, but you will also need to make a new mask from the path after you've edited it. When working with brushes, selections, and in several other places throughout GIMP, you’ll often see a checkbox marked “Antialiasing”, which will ensure that any actions you take already create smooth edges and lines.Īntialiasing is a very complex technical process, but for our purposes, it’s enough to know that it’s a technique used to create the appearance of smooth edges while drawing angles using a display made entirely out of square pixels.įor a perfect demonstration, look at the difference between the Pencil tool and the Paintbrush tool. You can now save the results in PNG format. Step 5: Go to the 'File' option and click on the 'Save As' button. Step 4: Once the Alpha Channel is added, you can now delete the white background from your image. The best method for getting smooth edges and lines in GIMP is to make sure that they start out that way from the beginning. Go to the 'Layer' option, click on the 'Transparency' option, and choose the 'Add Alpha Channel' option. The Best Option: Antialiased Lines And Edges Since you used the fuzzy select initially a couple of possibilities. Never any really quick way to remove a background other than if it is very plain and well defined. Blurring rough edges can’t add new detail, although it can still be useful in some situations. I use fuzzy select to lighten part of the background in this booking photo. If you want to paint somewhere, then you have to make sure that: This is the layers dialog (also part of the default UI layout): If in doubt, you can create a new layer of the same. Layers have a finite size in GIMP, and this size doesnt change automatically. It must be said that you won’t be able to produce perfect results with all of these techniques, but you might be able to create a result that you’re happy with, depending on the specific image that you’re working on. It is very likely that these 'boxes' are layers, text layers in this case. However, there are some basic fundamentals of how digital images work that should make you stop and think about whether what you want to achieve is really possible. GIMP stands for GNU Image Manipulation Program, and simple adjustments like this are a great example of the kind of difficult-to-describe image editing task that GIMP is usually great at.
