+ * 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 Microsoft "BMP"

+ * format (MS Windows 3.x and OS/2 1.x flavors).

+ * Either 8-bit colormapped or 24-bit full-color format can be written.

+ * No compression is supported.

+ *

+ * These routines may need modification for non-Unix environments or

+ * specialized applications.  As they stand, they assume output to

+ * an ordinary stdio stream.
