I need to use some animated GIF in my HB game written with OSLib, but I don't know how to do.
My question is: exist a library that allows me to implement animated GIF in my project?

tnx, and sorry for my bad english

you can simply display the frames of the gif one after the other with a time gap between ofcourse. use any libraryable to display pictures

There's no reason to use gif library.

There are 2 ways to create animations:

a)Create a large texture with all frames.
All textures must have the same width & height.

b)Just use simple image files(jpeg/png/tga/tga rle/anything), code a custom animation structure that will hold each texture.

Animating:

Increase frame time counter while its less than max frame time

Go to next texture if time counter reached max frame time

Render active texture

Calculating frame time :

time - last time + frame time counter.
