@Swift: I also just checked again, this still works (try calling _convert_colour on an existing PIL image to only test that part of the code). Or maybe your incolour is of the wrong shape? It should have length 4 (with the last value being the alpha value).

| Aug 23, 2018 at 9:32 | comment | added | Swift | It's just that I get an error about mis-shaped or something like that. Let me reproduce it, perhaps you can explain the error I get. I really want to convert the colour conversion to np as it seems everyone is shouting about how much faster it can process this data for me. | |

@Swift: It does work with color images for me (you can even call image.convert("RGBA") on it without anything changing). Not sure if this would work with grayscale images, though.
