win32 BITMAPCOREHEADER 结构体

The BITMAPCOREHEADER structure contains information about the dimensions and color format of a DIB.

typedef struct tagBITMAPCOREHEADER {
  DWORD bcSize;
  WORD  bcWidth;
  WORD  bcHeight;
  WORD  bcPlanes;
  WORD  bcBitCount;
} BITMAPCOREHEADER, *PBITMAPCOREHEADER;

Members

bcSize
The number of bytes required by the structure.

bcWidth
The width of the bitmap, in pixels.

bcHeight
The height of the bitmap, in pixels.

bcPlanes
The number of planes for the target device. This value must be 1.

bcBitCount
The number of bits-per-pixel. This value must be 1, 4, 8, or 24.

Remarks

The BITMAPCOREINFO structure combines the BITMAPCOREHEADER structure and a color table to provide a complete definition of the dimensions and colors of a DIB. For more information about specifying a DIB, see BITMAPCOREINFO.

An application should use the information stored in the bcSize member to locate the color table in a BITMAPCOREINFO structure, using a method such as the following:

pColor = ((LPBYTE) pBitmapCoreInfo + 
        (WORD) (pBitmapCoreInfo -> bcSize))
