Macro Definition Documentation

#define VDP_COLOR_TABLE_FORMAT_B8G8R8X8

8-bit per component packed into 32-bits

This format is an array of packed 32-bit RGB color values. Bits [31:24] are unused, bits [23:16] contain R, bits [15:8] contain G, and bits [7:0] contain B. Note: The format is physically an array of uint32_t values, and should be accessed as such by the application in order to avoid endianness issues.
