Fields

usType (USHORT)

Type of resource the file contains.

Possible values are shown in the following list:

BFT_BMAP

(0x4D42 - 'BM' for bitmaps)

BFT_ICON

(0x4349 - 'IC' for icons)

BFT_POINTER

(0x4540 - 'PT' for pointers)

BFT_COLORICON

(0x4943 - 'CI' for color icons)

BFT_COLORPOINTER

(0x5043 - 'CP' for color pointers)

cbSize (ULONG)

Size of the BITMAPFILEHEADER structure in bytes.

xHotspot (SHORT)

Width of hotspot for icons and pointers.

This field is ignored for bit maps.

yHotspot (SHORT)

Height of hotspot for icons and pointers.

This field is ignored for bit maps.

offBits (USHORT)

Offset in bytes.

Offset in bytes to beginning of bitmap pel data in the file, from the start of the definition.

bmp (BITMAPINFOHEADER)

Bitmap information header structure.
