[Radiance-general] Pvalue for converting to luminance

[Greg Ward]

Hi Chew,

Yes, pvalue -o -b * 179 and the ximage 'l' command should report the  
same values for the same pixels, though it's a bit difficult to know  
if you are in fact checking the same pixels -- the ximage 'p' command  
can help with that.

I guess this is moot since you couldn't compile ximage.  I believe  
Ecotect offers a Windows-ready substitute free of charge.

Best,
-Greg
