Making color transparent on animated gifs

Post by PaulLee »

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.
