[JAI] Adjust Brightness Tiff images.

Hello all,

I could really use some help on this one!

I am trying to figure out how to adjust the brightness of a tiff image.
I have
searched the archive and did not find exactly what I was looking for - I
don't really know where to start. If anyone could point me in the right
direction I would be most grateful.

Thanks,

-Frank

There are numerous operations which may be used to perform constrast
enhancement on an image regardless of its source format which is irrelevant
anyway once it is in Java2D/JAI. Among these are Lookup, Rescale, MatchCDF,
Piecewise and the various
{Add,Subtract,Multiply,DivideBy,DivideInto,Subtract,SubtractFrom}Const
operations.
