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 BITMAPFILEHEADER2 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.
bmp2 (BITMAPINFOHEADER2): Bitmap information header structure.
