- * Copyright (C) 1991-1996, Thomas G. Lane.
- * Modified 2009 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 write output images in PPM/PGM format.
- * The extended 2-byte-per-sample raw PPM/PGM formats are supported.
- * The PBMPLUS library is NOT required to compile this software
- * (but it is highly useful as a set of PPM image manipulation programs).
- *
- * These routines may need modification for non-Unix environments or
- * specialized applications.  As they stand, they assume output to
- * an ordinary stdio stream.

- * if PPM_NORAWWORD is defined (this can be done in the Makefile
