<b>Usage Notes</b>
<ol>
<li><span class="plaintext"> The default behaviour of <code>gxeps</code>is to
create a grayscale plot on a white background. The GrADS default rainbow colors
(color numbers 2 to 14) are converted into appropriate grey shades. User-defined
colors (numbers above 15) are translated to greyscale intensity based on their
<i>green</i> content only. </span>
<li><span class="plaintext"> For more information, see the section in the User's
Guide on <a href="imageoutput.html">Producing Image Output from GrADS</a>.
</span>
</ol>
<p>
<b>Examples</b>
<ol>
<li><code>gxeps -a</code>
<br>
<span class="plaintext">Prompts user for the input and output file names and
convert to greyscale on white background with page size A4. </span>
<li><code>gxeps -rc -i mytest.mf -o mytest.ps</code>
<br>
<span class="plaintext">Converts GrADS metacode format file </span><code><i>mytest.mf</i></code>
<span class="plaintext">to a color plot on black background and outputs the
result to PostScript file </span><code><i>mytest.ps</i></code>.
