[udig-devel] change pixel color

[simone amagliani <simone_a@xxxxxxxxxx>]

Hi to everybody, I use the version 1.1 of Udig and I'd like to create a plugin to modify pixel color of a layer but I don't know how to do it.
I try to explain what I'd like to do;
with the instruction "context.getSelectedLayer () " I get an object "ILayer" that points out the selected layer.Now I'd like to obtein  the matrix that represents the image (where each component of the matrix represents a pixel)to be able to change the values of pixel color (RGB).
How can I do?
I hope that someone could help me.
Thanks.
PS: I hope to have explained everything well, even if my English is not excellent.
Thanks
Simone
