BGR/BGRA alernative layouts & grayscale

BGR might be useful for some Windows or OpenGL APIs.

Structs

  • ABGR
    A+BGR
  • ARGB
    A+RGB
  • BGR
    RGB in reverse byte order
  • BGRA
    BGR+A
  • Gray
    Grayscale. Use .0 or * (deref) to access the value.
  • GrayAlpha
    Grayscale with alpha. Use .0/.1 to access.

Type Definitions

  • ABGR8
    8-bit ABGR, alpha is first. 0 = transparent, 255 = opaque.

    16-bit ABGR in machine’s native endian. 0 = transparent, 65535 = opaque.
  • ARGB8
    8-bit ARGB, alpha is first. 0 = transparent, 255 = opaque.
  • ARGB16
    16-bit ARGB in machine’s native endian. 0 = transparent, 65535 = opaque.
