In this example, we convert a horizontal sprite sheet of a sequence of static frames into an animated GIF of a bursting heart-shaped soap bubble. The sprite sheet consists of eight frames that have a size of 135 by 165 pixels. The first frame starts in the top left corner with coordinates (0, 0). Kenney.nl is based in the Netherlands and is producing some fantastic art for game. SpriteStack is a voxel editor suited for 2D artists featuring hand crafted retro renderer with animation support. It exports spritesheets, slices and vox models.
