BITMAPFILEHEADER structure (wingdi.h)

The BITMAPFILEHEADER structure contains information about the type, size, and layout of a file that contains a DIB.

Syntax

typedef struct tagBITMAPFILEHEADER {
  WORD  bfType;
  DWORD bfSize;
  WORD  bfReserved1;
  WORD  bfReserved2;
  DWORD bfOffBits;
} BITMAPFILEHEADER, *LPBITMAPFILEHEADER, *PBITMAPFILEHEADER;

Members

bfType

The file type; must be 0x4d42 (the ASCII string "BM").

bfSize

The size, in bytes, of the bitmap file.

bfReserved1

Reserved; must be zero.

bfReserved2

Reserved; must be zero.

bfOffBits

The offset, in bytes, from the beginning of the BITMAPFILEHEADER structure to the bitmap bits.

Remarks

A BITMAPINFO or BITMAPCOREINFO structure immediately follows the BITMAPFILEHEADER structure in the DIB file. For more information, see Bitmap Storage.

Examples

For an example, see Storing an image.
