Hello,
I'm trying to use convert to remove the background of my images. I have a folder of images. However, I have not been able to get this to work. How do I change the background color to black and set it to transparent. The colors of the background are very similar, but not identical. I'm running version 7.0.8-45, on a windows 7 machine, from the command line. The images are 180x180 png images. The edge all around the image is the background color, and the non-background part does not share the gray color of the background.

It is very hard to know what to tell you without seeing your images. Post them to some free hosting service and put the URL here.

Typical command is
if the background is near black, where XX% is the percent tolerance near black. Replace black with whatever your background color is.
