Using GIMP, I wish to fade an image inward from the edges, blending it with the neutral (white) background.
I have tried numerous things including feather edges, blur and Gaussian blur, but none of them produces a good result. Specifically, they all appear to blend the image outward or in both directions. I wish to fade the image inward from the edges, and without loss.
A tedious manual technique that I believe might work would be to:
- select the background
- grow the selection by 1 pixel
- adjust the brightness, then
- repeat 2. and 3. as many times as necessary
However, it strikes me that there is probably a tool that performs the same function.
