[magick-users] Serious Magick++ slow-down in underlying Reduce()

Fri May 16 01:04:44 PDT 2008

When I use different file format, like MIFF, MNG, it's a lot faster, but
when it comes to GIF, it's slow like hell.

I'd like to know what should I do prior to the writeImages() so that it
will get saved faster. Everything I save is animation.
