54 * This corresponds to the rounding convention used by the memory pixrect
55 * package (/usr/include/pixrect/memvar.h) of the SunWindows system.
56 * The ras_encoding field (always set to 0 by Sun's supported software)
57 * was renamed to ras_length in release 2.0. As a result, rasterfiles
58 * of type 0 generated by the old software claim to have 0 length; for
59 * compatibility, code reading rasterfiles must be prepared to compute the
60 * true length from the width, height, and depth fields.
