[Radiance-general] extracting brightness values from picture

[yijun huang]

Hi Prasanta,
 
I'm not sure how (in terms of code) you're trying to extract the luminance values and how you'd be processing them, but I've faced a similar task some time back and tried to document the syntax in a easy-to-reuse way.

at the bottom of the page, I've included a draft java file that eventually allowed me to access pixel values easily. (Did not have time to update with latest files...) Hope this is useful.
 
Cheers,
