[Radiance-general] Excluding zeroed values from averaged luminance

[parisa khademagha]

Hi Everyone,


I have a masked HDR picture generated by combining the original HDR with a
mask one. I want to calculate average luminance value of the masked HDR
picture without taking zeroed values into account. I am using ‘pvalue –o –d
–h –b –H masked.hdr | rcalc –e if’cond=$1-5;$1=$1’| total –m’. But the ‘if
condition’ is not working. Your help is very much appreciated.


Cheers,

Parisa
