&gt; 1.  Display first variable then save to an image file<br>
&gt; 2.  Clear screen, then display second variable<br>
&gt; 3.  Save to another file using first file as background (-b option)<br>
&gt; and specify an appropriate transparent color (-t option)<br>

&gt;&gt; Hi guys,<br>
&gt;&gt;<br>
&gt;&gt; I have been trying to combine two shaded variables in one image,<br>
&gt;&gt; for<br>
&gt;&gt; example precip &amp; cloud cover. I have tried the maskout function but<br>
&gt;&gt; the<br>
&gt;&gt; output looks to rough and pixelated. Can anybody suggest a better<br>
&gt;&gt; way to<br>
&gt;&gt; get a smoother result.<br>
&gt;&gt;<br>
&gt;&gt; Many thanks in advance<br>
&gt;&gt; Stuart.<br>
