Could you describe a use case?

I have to work with something like RGBQUAD which's layout is BGRX:

QQ, the rgbReserved represents the alignment?

At least it requires 4 bytes by that structure. Also note that Quartz 2D also has padded RGB: http://tinyurl.com/kdawwkl So I think GIL being a generic library is reasonable to fill such a requirement.

Now I have my pixel defined as:

template class pixel;

So RGBX becomes pixel.

So, pixel in memory looks like ( a letter representing a byte ): rgbxrgbxrgbx... pixel would be rgbxxrgbxxrgbxx... Is that correct? Do you already have some code which could be added to GIL? I would be willing to incorporate it and write tests and update documentation. I have added your proposal to my gil todo list but I'm afraid I don't have time right now. Christian
