I want to make a simple gradient in GIMP. The left edge and right edge should be white, the middle 100% transparent. The rate of change shouldn't be linear, I want the transparent part to be much wider than the left and right parts, giving the impression of the edges of the picture fading away when placed on a white background.

I went into the Gradient editor, but couldn't figure out how to use it. I could only add new segments by replicating existing ones, and then changing the endpoint colors at one of them also changed the colors of all other replicas.

I also tried opening copies of existing multi-color gradients for editing, such as Abstract 2, but I couldn't figure out how they are made. Whichever segment I selected, the context menu insisted that the end points are red and magenta, even when I was in the middle of a segment transitioning from sandy yellow to green.

I tried looking into the documentation, but if the solution is in there, I didn't find it.

Any ideas how I'm supposed to use the editor to get my gradient?

Custom Gradients in Gimp

Designing our custom gradients in Gimp (2.8) can be done from the gradients menu (CtrlG).

Here are steps to create a gradient with center transparent, white left, white right sides:


Create a new gradient
Choose actions from the right click context menu:


Select Left Endpoint's Color white and Right Endpoint's Color transparent:


Select Replicate Segment... - choose 2:


Mark the right segment as active with a mouse click on the bottom bar:


Select Flip Segment for Symmetry:


Define Blending Function for Segment:


left Spherical (increasing)
right Spherical (decreasing)


or any other setting to meet your needs.
Adjust segment handles (bottom triangles) with mouse until distribution as desired:


Give the gradient a sensible name (default Unitled), save, and done.


Of course other actions on the context menu list will help us to create those gradients we need.
