[Radiance-general] dumping xglaresrc result to a file

[Ery Djunaedy]

Thomas,

Thanks for the suggestions.

I am trying to avoid the first option that you suggested below. I get 
the impression that it is more difficult. Can you elaborate further?

I tried your suggestion to use xwd. The problem with this route is that 
both the ximage (which is called by xglaresrc) and the xwd are 
interactive programs. We end up trying to automate something that is 
interactive.

The catch is how to select the window to be dumped. The xwd by default 
asks the user to click on the window to be dumped. I tried to use the 
HDR file name as the window_name and pass it to xwd. Something like:

$ xwd -name sc01jd_view.hdr -out sc01jd_view.xwd

It works but (1) it assumes that no other window is on top of this 
window and (2) it captures what is displayed. The first catch means that 
we cannot do anything else on the computer while the script is working. 
The second catch means that if the xglaresrc picture is bigger than the 
monitor (e.g. netbook screen) the picture is actually cut.

For now, I think I can live with that.

Thanks,

Ery
