Is it possible to convert from pixels with different primitive types?

[ema2159]

Hello. I have been implementing a 3D renderer for fun, and one often has to manipulate images and pixels in f32, and convert them to u32 at the very end when rendering. However, I find myself constantly making awkward casts everywhere, and I was wondering if it was possible to convert from let's say Rgba<f32> to Rgba<u8> somehow? I think it is possible between images using the DynamicImage type and its conversion functions, but I didn't find a straightforward way of doing the same between pixels. Is there any way to do this? If not, why not?

Thanks beforehand,

Emmanuel
