The pyglet.graphics module is a low-level abstraction of OpenGL vertex arrays and buffer objects. It is intended for use by developers who are already very familiar with OpenGL and are after the best performance possible. pyglet uses this module internally to implement its new sprite module and the new text rendering module. The Graphics chapter describes this module in detail.
The pyglet.sprite module provide a fast, easy way to display 2D graphics on screen. Sprites can be moved, rotated, scaled and made translucent. Using the batch features of the new graphics API, multiple sprites can be drawn in one go very quickly. See Sprites for details.
The pyglet.image.load_animation function can load animated GIF images. These are returned as an Animation, which exposes the individual image frames and timings. Animations can also be played directly on a sprite in place of an image. The Animations chapter describes how to use them.
The pyglet.image.atlas module packs multiple images into larger textures for efficient rendering. The pyglet.resource module uses this module for small images automatically, but you can use it directly even if you're not making use of pyglet.resource. See Texture bins and atlases for details.
Images now have anchor_x and anchor_y attributes, which specify a point from which the image should be drawn. The sprite module also uses the anchor point as the center of rotation.
Textures have a get_transform method for retrieving a TextureRegion that refers to the same texture data in video memory, but with optional horizontal or vertical flipping, or 90-degree rotation.
