Well it'd be more of the number of times to divide the image.
Say, in this example. You have 4 16x16(a 32x32 block) tiles that animate(maybe water tiles), and the water has 3 frames of animation. You'd tile each frame of the animation horizontally, save it, and do:
addtiledef3(watertiles.png,world_,0,80,3);
And it would animate the tiles through Graal, and not by just displaying a gif. Much like it does with the flower tiles, though a bit different as each frame won't have to be stored in the tileset image. The size of the image would look akin to the one attached.
