I have a GIF file that has a transparent section. I want to replace that with just plain white (or some other colour), so that there is no transparent parts. Can I do this on the command line with ImaageMagick? I'm OK if the image has to change from a .gif to something else. I tried to convert it to a jpg and the tramsparent parts were black. Is there a way to customize that?
I'm using ImageMagick on Ubuntu 9.10 Karmic Koala
