Struct qt_gui::QRgba64

#[repr(C)]pub struct QRgba64 { /* fields omitted */ }

The QRgba64 struct contains a 64-bit RGB color.

C++ class: QRgba64.

C++ documentation:

The QRgba64 struct contains a 64-bit RGB color.

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

QRgba64 can be used 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.
