Detailed Description▲

QRgba64 is a 64-bit data-structure containing four 16-bit color channels: Red, green, blue and alpha.

QRgba64 can be used as a replacement for QRgb when higher precision is needed. In particular a premultiplied QRgba64 can operate on unpremultiplied QRgb without loss of precision except for alpha 0.
