Data:

SCREEN_FORMAT_BYTE

SCREEN_FORMAT_RGBA4444: 16 bits per pixel (4 bits per channel) RGB with alpha channel

SCREEN_FORMAT_RGBX4444: 16 bits per pixel (4 bits per channel) RGB with alpha channel disregarded

SCREEN_FORMAT_RGBA5551: 16 bits per pixel, 2 bytes containing R, G, and B values (5 bits per channel with single-bit alpha channel)

SCREEN_FORMAT_RGBX5551: 16 bits per pixel, 2 bytes containing R, G, and B values (5 bits per channel with single-bit alpha channel disregarded)

SCREEN_FORMAT_RGB565: 16 bits per pixel; uses five bits for red, six bits for green and five bits for blue.; This pixel format represents each pixel in the following order (high byte to low byte): RRRR RGGG GGGB BBBB

SCREEN_FORMAT_RGB888: 24 bits per pixel (8 bits per channel) RGB

SCREEN_FORMAT_RGBA8888: 32 bits per pixel (8 bits per channel) RGB with alpha channel

SCREEN_FORMAT_RGBX8888: 32 bits per pixel (8 bits per channel) RGB with alpha channel disregarded

SCREEN_FORMAT_YVU9: 9 bits per pixel planar YUV format.; 8-bit Y plane and 8-bit 4x4 subsampled U and V planes. Registered by Intel.

SCREEN_FORMAT_YUV420: Standard NTSC TV transmission format.

SCREEN_FORMAT_NV12: 12 bits per pixel planar YUV format.; 8-bit Y plane and 2x2 subsampled, interleaved U and V planes.

SCREEN_FORMAT_YV12: 12 bits per pixel planar YUV format.; 8-bit Y plane and 8-bit 2x2 subsampled U and V planes.

SCREEN_FORMAT_UYVY: 16 bits per pixel packed YUV format.; YUV 4:2:2 - Y sampled at every pixel, U and V sampled at every second pixel horizontally on each line. A macropixel contains 2 pixels in 1 uint32.

SCREEN_FORMAT_YUY2: 16 bits per pixel packed YUV format.; YUV 4:2:2 - as in UYVY, but with different component ordering within the uint32 macropixel.

SCREEN_FORMAT_YVYU: 16 bits per pixel packed YUV format.; YUV 4:2:2 - as in UYVY, but with different component ordering within the uint32 macropixel.

SCREEN_FORMAT_V422: Packed YUV format.; Inverted version of UYVY.

SCREEN_FORMAT_AYUV: Packed YUV format.; Combined YUV and alpha

SCREEN_FORMAT_NFORMATS

Library:

libscreen (For the qcc command, use the -l screen option to link against this library)

Description:

Formats with an alpha channel will have source alpha enabled automatically. Applications that want the Screen library to disregard the alpha channel can choose a pixel format with an X.

This enumeration is used when setting the SCREEN_PROPERTY_FORMAT property.
