Hi Guys,
Thanks for quick replies. This is what I was asking for, but it did not fully solve my problem. My RGB image is very dark for some reason, and even on the white background it appears mostly blackish. I can see some red, green and blueish hues, but the image is fully opaque, even though I used the -fim flag for 3dThreetoRGB. Is there a way to rescale the RGB to have better brightness or contrast, without changing the colors, to create a clearer and more visible image? I can upload an example if you would like to see what I'm working with.
