Description

This function sets the source parameters for the embedded frame buffer (EFB) to copy to the texture image. This feature is useful when creating textures using the graphics processor (GP).

The GP will copy textures into the tiled texture format specified in the GXCopyTex function. The GP always copies tiles (32B), so image widths and heights that are not a multiple of the tile width will be padded with undefined data in the copied image. Also, the allocated image size in main memory must be a multiple of 32B. For more information, see the GXGetTexBufferSize function.
