Pixel Formats

The graphics system supports a variety of pixel formats to represent pixel buffer data in RGB, YUV and luminosity formats.

There is an API to specify and retrieve system-defined and user-defined pixel formats. The pixel formats are defined by the type TUidPixelFormat, which represents the underlying layout of the pixels. New pixel formats can be defined by using a unique UID value.

• RGB Pixel Formats
  This topic provides detailed information about the supported RGB pixel formats.
• YUV Pixel Formats Overview
  The YUV model defines a color space in terms of one luma (Y) and two chrominance (UV) components. The YUV color model is used for analog encoding of color information in television transmissions (PAL). Y stands for the luminance component (the brightness) and U (Cb) and V (Cr) are the chrominance (color) components.
• Luminosity Pixel Formats
  This topic provides detailed information about the supported luminosity pixel formats. These formats are used to represent grayscale images.
• Color Conversion
  This topic describes the color conversion between RGB and YUV. The details depend on which YUV color space is used.
