I have a large number of images, some of which have a colour range that is different to the rest. I have a csv file that lists each filename and whether it requires adjustment or not.
I would like to be able to modify the red, green and blue for those images using a quadratic formula, something like:
set Red=if([needsadjustment]=1,max(min(Red^2*-0.004+Red*1.78+57,255),0),Red)
and similarly for green and blue channels.
Can anyone advise if this is possible using FME please?
Thanks
Rob
