it would be that way, but perhaps having the -t 0 option before the -b command
would make a difference?<o:p></o:p></span></p>

ended up writing external code to do some things similar. But you may want to
look at OpenGrads' gxyat command… I don't recall if it has a background
image option, but it may be something to check out. I know that the images are
much smoother and nicer looking, but file sizes will be much larger if
that's a concern.<o:p></o:p></span></p>

<p class=MsoNormal style='margin-bottom:12.0pt'>Hello GrADS Users,<br>
<br>
I am trying to get a background image behind my precip/ptype products in GrADS
and I am having absolutely no luck.<br>
<br>
GrADS versions that I have tried:<br>
<br>
Grid Analysis and Display System (GrADS) Version 2.0.a9<br>
Grid Analysis and Display System (GrADS) Version 2.0.a7<br>
<br>
Error that I receive: <br>
<br>
PRINTIM error: background image open error<br>
<br>
printim example that I am using:<br>
<br>
printim precip_NE_1.png png x570 y435 -b NE.png -t 0<br>
<br>
I am using the full path for the output image and background image, I just
removed it from the above command.<br>
<br>
This is the png image that I would like to use (or it will look something like
this):<br>
<br>
<a href="http://jeffsweatherservice.com/images/NE.png">http://jeffsweatherservice.com/images/NE.png</a><br>
<br>
The above image would be a background to an image like:<br>
<br>
<a href="http://jeffsweatherservice.com/grads/nam/precip_NE_2.png">http://jeffsweatherservice.com/grads/nam/precip_NE_2.png</a><br>
<br>
Does anyone know how to make this work? Or does anyone have another way
that I could get a green/brown basemap with blue water to replace the plan
white background? I have the basemap stencil working on temperature
products, but that will not work well for precip/ptype products.<br>
<br>
Any help/insight here would be greatly appreciated.<br>
<br>
Sincerely,<br>
<br>
<br>
Jeff Chabot<br>
