Could this be considered a breaking change? Although it's fixing unusual and perhaps undocumented behaviour. Might be worth adding a brief note in the release notes? We could also wait for the Pillow 13.0.0 release in October, but that's probably unnecessary? |

#9395 changed the C setimage() so extents needed to be passed in. However, I've realised that both before and after that, the C setimage() never accepted None. For background, #1938 added the Python setimage(), which accepted None for the extents, and tested for it accordingly. #8285 added None as a possible value to the extents type hint in a tile. I think we should aim for the same behaviour with the C and Python setimage(). It is fair enough to say that removing None as a possible extents value for Python setimage() is a breaking change, so I'm now going in the opposite direction with this PR - allowing None as an extents value in the C setimage(). |
Sorry, something went wrong.
