How do you make images gradient-fade on GIMP? I need an image to merge into another one and I've spent hours trying to find the tool to do it. The closest I got to doing it was using the Gradient tool in Color Erase mode, but it never completely gradient-faded the image. It would be 100% opaque on one end but not 0% on the other.
I think you know what I'm talking about when I say this: I just need to know how to make an image go from 100% alpha on one side to 0% alpha on the other. I think that should achieve the image-merging affect I desire.
