Detailed Description

Encapsulated a 4-byte pixel in BGRA format for use with Direct2D.

Definition at line 38 of file pixel.h.

Constructor & Destructor Documentation

scope::BGRA8Pixel::BGRA8Pixel ( )
inline

Initialize to opaque black.

Definition at line 52 of file pixel.h.

scope::BGRA8Pixel::BGRA8Pixel ( const uint8_t &  val)
inline

Sets all colors to val (=> gray) and alpha to opaque.

Definition at line 60 of file pixel.h.

scope::BGRA8Pixel::BGRA8Pixel ( const uint8_t &  vB,
const uint8_t &  vG,
