Wondering if someone could give me a little help. I used an stl i modeled to create a grayscale heightmap for CNC carving but the outer edges are too steep (see red circle).
I figured I could fix this by applying a gradient around the boundary selection of the image in gIMP to soften the edge between my greyscale image and the black background.
After some google searching I saw there was a tutorial for gradient border select, and the image looks to be similar to the affect I'm trying to achieve, but it was on gimplearn, which seems to no longer exist.
I've included pictures of the greyscale image, what the result is in my carving software, and a picture of the effect i'm trying to achieve.
Any and all help appreciated!
Edit: seems most image hosting service are blocked on my work's network with the exception of tiny pic, which doesn't seem to load into the post correctly, I have included the links below.
