creating gif animations

Question

I read some where it was possible to create a gif by adding frames to it in a browser. Does that mean on the server you can add frames to it by using cat?

Are there other file types that are so simple to work with? What would be something good to do to better understand file headers that is very simple and would help explore sending data over an arduino ( which is of course a seperate issue! ).

Answer 1

To create an animated GIF using command line, I would use the excellent command line tools from the package Imagemagick:

convert -delay 10 *.gif animation.gif
