 - * rdbmp.c

 - * Copyright (C) 1994-1996, Thomas G. Lane.
 - * Modified 2009-2010 by Guido Vollbeding.
 - * This file is part of the Independent JPEG Group's software.
 - * For conditions of distribution and use, see the accompanying README file.
 - *
 - * This file contains routines to read input images in Microsoft "BMP"
 - * format (MS Windows 3.x, OS/2 1.x, and OS/2 2.x flavors).
 - * Currently, only 8-bit and 24-bit images are supported, not 1-bit or
 - * 4-bit (feeding such low-depth images into JPEG would be silly anyway).
 - * Also, we don't support RLE-compressed files.
 - *
 - * These routines may need modification for non-Unix environments or
 - * specialized applications.  As they stand, they assume input from
 - * an ordinary stdio stream.  They further assume that reading begins
 - * at the start of the file; start_input may need work if the
 - * user interface has already read some data (e.g., to determine that
 - * the file is indeed BMP format).
 - *
 - * This code contributed by James Arthur Boucher.
