DXRAWSURFACEINFO structure

Contains information needed by the IDXRawSurface interface to initialize a DXSurface from a custom raw surface.

Syntax

typedef struct DXRAWSURFACEINFO {
  BYTE          *pFirstByte;
  long          lPitch;
  unsigned long Width;
  unsigned long Height;
  const GUID    *pPixelFormat;
  HDC           hdc;
  DWORD         dwColorKey;
  DXBASESAMPLE  *pPalette;
} DXRAWSURFACEINFO;

Members

• pFirstByte
  Pointer to a value of type BYTE that indicates the origin of the raw surface.

• lPitch
  Value of type long that indicates the number of bytes from the beginning of a row to the beginning of the next row. This number can be negative.

• Width
  Value of type unsigned long that indicates the width of the raw surface, in pixels.

• Height
  Value of type unsigned long that indicates the height of the raw surface, in pixels.

• pPixelFormat
  Pointer to the pixel format of the raw surface.

• hdc
  HDC of the raw surface. You should create a memory device context for the raw surface so that clients can make GDI calls to manipulate the surface.

• dwColorKey
  Value of type DWORD used as a color key for the raw surface. The high byte of this value must equal 0xFF for the color-keyed surface. The lower three bytes contain the native data type.

• pPalette
  Pointer to an optional palette used for the pixel colors of the raw surface.
