[magick]

You can resize an animated GIF like this, for example:

• convert movie.gif -resize 50% small_movie.gif

GIF is a horrible image format for general images, as because of this resizing can produce a lot of problems with regard to transparency, and color handleing between frames. It can especially cause major optimization problems.

IM Examples has unfortunatally not looks at this probelm fully,

but is getting there, especially now that the new destions on color quantization and dithering is basically complete.

I suggest you look at it and of course submit your commits and additions to me.
