/***************************************************************************
* *
* ras.h Sun rasterfile.h 1.11 89/08/21 *
* *
* Version 2.00 (16-Nov-1993) *
* *
* NOTES: *
* Each line of the image is rounded out to a multiple of 16 bits. *
* This corresponds to the rounding convention used by the memory pixrect *
* package (/usr/include/pixrect/memvar.h) of the SunWindows system. *
* The ras_encoding field (always set to 0 by Sun's supported software) *
* was renamed to ras_length in release 2.0. As a result, rasterfiles *
* of type 0 generated by the old software claim to have 0 length; for *
* compatibility, code reading rasterfiles must be prepared to compute the *
* true length from the width, height, and depth fields. *
