[Radiance-general] is there a way to extract image information in text format?

[Andrew McNeil]

Chien,
If you have rendered images you can use pvalue to extract pixel data.  Make
sure you use rpict -i if you what illuminance instead of luminance values.
Or you can use rtrace -I to generate illuminance data for a grid of points.
Best,
Andy
