image Decode to sRGB

Many image formats store image data in a color space other than sRGB. It would be nice to be able to be able to request sRGB and have the stored image data converted to sRGB as needed.

I'm interested in implementing this using qcms to do the conversion and was hoping for some pointers on how to expose and plug in this kind of functionality.

An ImageBuffer derefs into a slice. I think you should just be able to pass that to qcms::Transform::apply(...).

Would the Pixel trait then have some way of obtaining the color space of the source data?

Unfortunately, no. Some of the individual decoding crates provide a bit more information, but we don't have any common abstraction for that (yet) at the level of this crate. You'd probably have to get that information out of band
