| [SDL_GPUCopyPass](SDL_GPUCopyPass) *                     | **copy_pass**   | a copy pass handle.                                                                                         |

| const [SDL_GPUTextureLocation](SDL_GPUTextureLocation) * | **destination** | a destination texture region.                                                                               |
| [Uint32](Uint32)                                         | **w**           | the width of the region to copy.                                                                            |

## Remarks

This copy occurs on the GPU timeline. You may assume the copy has finished
in subsequent commands.

This function does not support copying between depth and color textures.
For those, copy the texture to a buffer and then to the destination
texture.

## Version

This function is available since SDL 3.2.0.
