Hi All,
I am trying to achieve a certain look on a greyscale/height map image for a cnc project I am working on.
Im new to gimp so Ill try to be explicit as Im not sure of exact terms.
I started with an image that only has two colors to my knowledge (or at least doesnt have a lot of colors so that if you looked at a height map of the image it would be mostly 0s and 1s. I switched to greyscale mode and played with contrast and brightness to get the greyscale sharper.
This is where I am.
I am trying to figure out how to basically apply a filter (or modify the values of the pixels in some way ) over that grey scale image I created so that it becomes a height map where the highest point is in the center and as we move towards the edges of the image it gradually falls off in height. so that you get a domed look but still retain details of the image. Is this even a thing that makes sense? Is gimp the right program for this sort of thing?
Appreciate it!
