EDDGPEPixelFormat 

This data type identifies a specific memory layout associated with a surface.

Syntax

typedef enum EDDGPEPixelFormat{
  ddgpePixelFormat_1bpp = 0,
  ddgpePixelFormat_2bpp, 
  ddgpePixelFormat_4bpp, 
  ddgpePixelFormat_8bpp, 
  ddgpePixelFormat_565, 
  ddgpePixelFormat_5551, 
  ddgpePixelFormat_4444, 
  ddgpePixelFormat_5550, 
  ddgpePixelFormat_8880, 
  ddgpePixelFormat_8888, 
  ddgpePixelFormat_YUYV422, 
  ddgpePixelFormat_UYVY422,
  ddgpePixelFormat_YV12,
  // some generic types
  // Use dwPixelFormatData in conjunction with this info
  ddgpePixelFormat_15bppGeneric, 
  ddgpePixelFormat_16bppGeneric, 
  ddgpePixelFormat_24bppGeneric, 
  ddgpePixelFormat_32bppGeneric, 
  ddgpePixelFormat_UnknownFormat,
  // you can assign custom formats starting with this value
  ddgpePixelFormat_CustomFormat = 0x1000
};

Remarks

If a surface type required by your driver is missing from the list of supported types, use one of the generic types to indicate the bit-depth of your surface. A custom pixel-

format data field is offered in data structures that rely on the EDDGPEPixelFormat data type. Use this field to store additional information for your driver.
