Hello,

I'm still looking for a plugin which returns the brightness value of each
single pixel in the picture according to the XY coordinates. I'd like to
extract this data to Excel and calculate later. Does anyone knows
something about it? is it available as plugin or just a simple macro?
thanks in advance.

greetings,
