color correction on giant tiff on the fly
I have to handle VERY large (1-2GB) Tiff files, and only need to do some RGB manipulations on pixels, where I only make local corrections (color of a modified pixel is only depending on its old values, but not on e.g. neighbor pixels).
Is their a way to read the file as some kind of Pixel stream, make adjustments on the RGB values, and write the stuff immediately to another file? I will not have enough memory to store the entire file in RAM (or at least I hope I could avoid it)
Thx for any hints...
If you have different hints than JAI, I also would appreciate them!
