<pre>
const char *filename - the name of the file to be written.
int quality - integer value that controls degree of lossiness in
JPEG file. The value of quality ranges from 0-100, with 100 being
the least amount of loss, and smaller numbers producing increasing
amounts of error. Smaller numbers result in smaller output file size.
const RMimage *toWrite - the RMimage object that will be written
to the file in JPEG format.
</pre>
<menu><P>
Writes a JPEG image raster file named "filename" using the input RMimage
object "toWrite" as the source. The quality of the JPEG file is determined
by the "quality" parameter, which ranges from 0-100. Smaller quality values
produce greater amounts of compression, smaller files and poorer image
image quality. Larger quality values produce larger files, less compression,
and better image quality.
</P>
<P>
Returns RM_CHILL upon success, or RM_WHACKED upon failure.
</P>
<P>
This routine works only on RMimage objects that contain RGB images.

<pre>
const char * filename - a character string, the name of the file
containing a JPEG image to read (input).

<menu><P>
This routine will open and read a JPEG image file. If there are
no errors, this routine will create and return to the caller an
RMimage object containing the raster image data. If there is a
problem reading the JPEG file, NULL is returned.
