[Radiance-general] Falsecolor auto scale

[Giovanni Betti]

Dear All,

I am trying to programmatically convert a number of radiance images into
their falsecolor equivalent. As the images display a wide range of
possible values I am trying to figure out a method for automatically
adjust the scale.

The manual page of falsecolor reads: "If the argument given to -s begins
with an "a" for "auto," then the maximum is used for scaling the
result." Which is exactly what I need, unfortunately it does not work
for me: no error is thrown but the scale is always the standard 0 to
1000.

This is the syntax that I am using:

" Falsecolor -ip mypic.hdr -s a -n 10 -l Lux > mypic_fc.hdr "

I am using Radiance 3.9 on Windows, which might be the reason.

I have also tried this on the real useful falsecolor2 by Thomas Bleicher
(thanks!!) and in this case I receive the error 'bad option'.

Does anyone have any suggestion/clue?

Thanks in advance,
Best,

Giovanni
