Ben,

I seem to recall having a similar problem several years ago. I think that it is a 
function of the data which seems to have a native resolution of 640x350 as far as WXP is 
concerned (but I am not sure). Our solution was to create a 640x480 image and then use 
the "convert" utility to increase the size.

$outfile1 was our 640x480 image and $outfile2 contains1024x768

/usr/local/bin/convert -geometry 1024x768 $outfile1 $outfile2

$outfile1 was our 640x480 image and $outfile2 contains1024x768

It does a respectable job, but it's not perfect. We display it on a 42" plasma 
screen and it's not bad.

Subject: [wxp] Global satellite images

WXPers,

I'm trying to generate large-ish (ideally 1280x986) images for display on
large screens our department recently bought.  One of the images I wanted to
put up was a global satellite view.  Using the command:

xsat  -ge=1280x968 -if=sat_ir_g -cu=la -de=d

I get the data and the map plotted in separate parts of the plot, as seen
in:

http://web.ics.purdue.edu/~bcotton/mollweide.gif

Is this a limitation of the global satellite files that come in off the IDD
or is there something I can do to force it to work?


Thanks,
BC
