I am creating MMaps for my server.

When flattening the image I've had a range of RGB spots (different grays) that make the mmap image look awful.

I have slowly been batch editing RGB(X,X,X) to RGB(1,1,1) but in GIMP you can only do 1 target at a time.

Anyone have any ideas how to mass colour change pixels on images?

If you just need to color swap then it's quicker in Photoshop imo using Actions.

Only problem is Photoshop cannot flatten to a BLACK background, only white.. :(

I can do patch work anyway, but my main issue is there is like 30-40 maps I need to do it for

I might just bite the bullet and do it to be honest, as after that it's only needed for every new map set.
