Detailed Description

A structure representing RGB color information.

The RGBA information is available either as separate r, g, b, or as a packed std::uint32_t rgba value. To pack it, use:

int rgb = ((int)r) << 16 | ((int)g) << 8 | ((int)b);

To unpack it use:

int rgb = ...;
std::uint8_t r = (rgb >> 16) & 0x0000ff;
std::uint8_t g = (rgb >> 8) & 0x0000ff;
std::uint8_t b = (rgb) & 0x0000ff;
