I'm looking for a software that would do that (actually, I'm doing that manually...):
- convert a file that has some sprites of an animation in sequence (vertically or horizontally concatenated) to a gif file
- can be configured according to the width and height of each sprite
- can be configured to recognize the sprites on vertical or horizontal concatenation
- can be configured to take sprites in other orders than the concatenation order

E.g.: I would like to animate these files ("googled" examples):
