Hi,
This is my first post, please be kind
I have a couple of animated gifs that I downloaded and I'd like to make a specific color (black) transparent in each of the layers of the gifs. Is there a simply way to do it via the command line?
Best wishes
Paul

Code: Select all
convert image.gif -coalesce -transparent black -layers optimize result.gif
If the color is not perfectly black, then you can add -fuzz XX% to consider near-black as if it were black.
Code: Select all
convert image.gif -coalesce -fuzz 5% -transparent black -layers optimize result.gif

Please, always provide your IM version and platform when asking questions, since syntax may differ. Also provide your exact command line and if possible your images.
