[Radiance-general] pcomb to change pixel brightness values

[Humann Chris]

Dear list,

Once again I'm stuck scratching my head over pcomb functional syntax.  

I'd like to be able to modify an HDR image such that any pixel of a specific brightness li(n)  is changed to a specific color of a given value and the original pixel values are maintained for all the other pixels below the brightness threshold.



As always thanks,
Chris
