HOW TO: Decompress CCITT Fax Group 4 buffer

The attached Visual C++ 2010 project shows how to decompress a 1-bit CCITT G4 image stored in a memory buffer, then save the image in an uncompressed 1-bit Windows BMP file.
The project uses the following C DLL functions from LEADTOOLS v18:
L_SetLoadInfoCallback()
L_LoadBitmapMemory()
L_SaveBitmap()
L_FreeBitmap()

The buffer properties need to be known in advance. The attached ZIP file contains a sample G4 image without a TIF header and with the following properties:
Format: Fax Group4
Orientation: TOP LEFT
Photometric Interpretation: Black on white
Width: 2048 pixels
Height: 2048 pixels
Bits per pixel: 1 (like all G4 images)
