Re: Animated images in mails
Today I got animated spam. The first frame only with dots an lines, the
second frame with spam text, the third frame again with dots and lines. The
duration of the text frame is very long, the others are very short.
Is there a command line utility which can extract animated GIFs?

first frame...
FuzzyOcr is using two different tests... for few frames, it simples
glues them to one frame using imagemagick,
for many frames, it picks the best and tests that..

Sure. giftopnm will do it. The FuzzyOCR plugin is using some other tool
that will also do it, I don't recall what just at the moment.

Surely... but I don't use Spamassassin, I am using my own program :)

That is what FuzzyOcr does automatically for you :) (If you set the
gif frame option in the cf file to a low value... with 1 it will
always be used..)

Thanks, gifasm works very well. Seems that I only have to choose the biggest
one of the output files, it contains the text.

Various... imagemagick can either extract them or put them into one
image, gifasm can split them into multiple files, etc.
FuzzyOcr utilizies both as needed to scan animated gifs.
