Jeff,<br>What color table are you using? Are you sure you have a #0 color? I know that's supposed to be the background, but perhaps you are overwriting it with some other color that has the same color as your background but a different color number.<br>

<h1 style="font-weight: normal;"><font size="2">Dear GrADS Users,</font><br></h1><h1 style="font-weight: normal;"><font size="2">I have been trying to apply a basemap to my precip/ptype shaded contour products on my
personal website for some time now. I have brainstormed and searched the GrADS
online documents and have come up with ideas, but they have never worked. My latest
idea was to use Google Maps terrain data as a background to the map. I
thought it was a good idea, but I discovered that I still cannot
resolve the issue in that precip = 0 shows either all white or all black
depending on what I choose for the background, covering up my basemap.
I really thought the following command would have resolved that issue,
but it did not:<br><br>printim precip_NE_1.png png x570 y435 -b NE.png -t 0</font> </h1><h1 style="font-weight: normal;"><font size="2">Versions:</font></h1>GrADS: 2.0a9<br>OS: Fedora 13<br>Sample: <a href="http://jeffsweatherservice.com/grads/nam/ptype_NE_2.png" target="_blank">http://jeffsweatherservice.com/grads/nam/ptype_NE_2.png</a><br>
