Hi Robert- Yeah no worries, I just ended up mucking with the bits directly, I was just wanting to use built-in functions if they were available.
For anyone searching with a similar issue (this was in Windows btw), I ended up just setting all of the alpha elements to 0xFF within my GL_BGRA image. I was going to take it to GL_BGR, but the CF_DIB clipboard format wants a 4-byte aligned width, so instead of padding or cropping the original captured image, I just kept it in a 4-byte per-element format. If you were to keep it in BGR and you don't have it properly aligned the image will be sheared and look very wrong.
