Hi,
I wonder if there's a way so that I can remove certain colors from some number of pictures at once, like white and absolute blue using a command line scripting operation.
Thanks,
Color Removal

Re: Color Removal
what do you mean by remove? make transparent?
If all the pictures are in one directory, you can use mogrify. If you only have a few images, you can use convert and list all the images and apply the same commands to remove those colors.
If you want to make transparent an exact color, use
-transparent somecolor
if you want to make transparent some color and those colors very near, then use
-fuzz XX% -transparent somecolor
where XX% is the percent difference in color that you want to include and make transparent
