It is possible to make Image Background Transparent in GIMP. What do I mean by making it transparent? Simply, you can make the Image Background Transparent in GIMP by using another layer with a black background as an overlay. So, what happens when we use the black layer?
Well, we can just create a red circle and a red border around it. And, we will use a hard-edged rounded rectangle shape to go around it. However, what happens when we use a blue shape? Nothing, the color is removed!
The problem of Image Background Transparent in GIMP has always been the visibility of the outline of the blue rectangle around the shape. Even though we get rid of that outline, there’s still an outline. I am going to show you a simple way to fix that problem. Please note that you should not remove the edge of the gray mask before applying it to the actual shape.
How to Image Background Transparent in GIMP
If you look at the image below, the first three layers are opaque white. The last one is transparent. The first layer will always be opaque black. This is why the border round the blue rectangle is invisible. Simply make it transparent by adding some solid color. The border around the white shape is now transparent.
Now, if you apply the same technique to the outer shape, you will see that it becomes transparent. This can be seen in the screenshot below.
If you look at the shape, you will notice that the last transparent layer is now transparent as well. You may now add a mask to this layer and add a stroke around the outer edge.
So, the inner shape is now transparent. Let’s apply the same technique for the other shape to make it also transparent.
Let’s add the transparent black outline to the top layer. When we apply this, you can see that it can blend nicely with the top layer. Please note that I did not remove the layer blending from the gray layer before applying it to the outer edge of the shapes.
This technique is similar to the one used in GIMP in creating Image Background Transparent in GIMP. If you are having trouble with the transparency of your shapes, this can help you. This technique may not be right for all cases, but it can still be very useful.
Sometimes, we need to learn some soft skills. As I said before, I have learned these soft skills when I used this technique in GIMP.
Although I do not do GIMP anymore, I still use this technique often. I often find myself repeating the same technique when I make Image Background Transparent in GIMP. This is a very simple technique to do, which can save you a lot of time when you are working on a certain image.
