There are 11 different image formats; these are built directly into GX, so they remain the same across all GameCube and Wii games. Rather than storing pixels in a linear left-to-right order, GX textures encode pixels in large blocks. The size of the block varies depending on the image format. | There are 11 different image formats; these are built directly into GX, so they remain the same across all GameCube and Wii games.

For example, suppose you have a format that stores 4x4 blocks. Pixels 1-4 of the image will make up the first row of the first block; pixels 5-8 will make up the second row; 9-12 will make up the third row; 13-16 will make up the fourth row, completing the block; and | For example, suppose you have a format that stores 4x4 blocks.
