Hi,
I have an 8bit greyscale image which I need to convert to a 1bit mono image based on a threshold value (0 - 256). I thought the LBitmap::DynamicBinary() function would do this but it seems that the local contrast test is getting in the way, and setting uDim to 1 doesn't work either.
I simply need it to check each grey pixel in isolation against my threshold and change it to 0 if its less and 255 (or 1) if its greater. Is there a way to get DynamicBinary() to do this or some other function?
Thanks,
Dave.

Dave,
Have you taken a look at LBitmap::IntensityDetect? I think this is the function you need. Let us know. Thanks,
Gabriel
