BITMAPCOREHEADER

The BITMAPCOREHEADER structure contains information about the dimensions and color format of a device-independent bitmap (DIB).

typedef struct tagBITMAPCOREHEADER { // bmch 
    DWORD   bcSize; 
    WORD    bcWidth; 
    WORD    bcHeight; 
    WORD    bcPlanes; 
    WORD    bcBitCount; 
} BITMAPCOREHEADER; 
 

Members

bcSize

Specifies the number of bytes required by the structure.

bcWidth

Specifies the width of the bitmap, in pixels.

bcHeight

Specifies the height of the bitmap, in pixels.

bcPlanes

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

bcBitCount

Specifies 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 device-independent bitmap, 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))
