Hi Simone:

The catalog allows you to access the image using the Java Advanced Imaging and ImageIO. I do not know much about using these for editing images in place; they do provide a Raster model that is used for sampling values.

Now I try to explain better what I want to do.
I use images tif, and I want to change color to the pixels going to directly act on the matrix that the image represents.
With the istruction "getContext () " I know the selected layer, now I would want to do:
- to find the matrix that represents the image;
- with cycles "for" to modify the value of the colors of the pixels; 
- to replace the old layer with the modified one;

Could someone tell me as I can do?
Thanks

PS:I hope that my English is comprehensible  :D

Simone
