[Qt-interest] Qt painting can work with 32bit A-RGB (8bit per channel). How can i realize 32bits per channel?

No. Qt doesn't support channels more than 8 bits. You will have to 
down-sample your data.

[Rant]
Qt doesn't even support reversed channel order, making it hard to 
interface with platform data in different endians.

And no direct grayscale support is even more puzzling.
