* 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.
