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

Hi Simone,
I never went deep into the udig 1.1 raster stuff, but I could help you
with the coverages model of udig 1.2.
Any chance for you to move to use udig trunk instead of the udig 1.1?

Ciao
Andrea

if it is possible I'd like to stay with the version 1.1 of Udig.
I have seen that I could resolve my problem replacing the actual version of gt2-renders with the version 2.5.4.
is it true?
it is possible to do or it is preferable to pass to the version 1.2?
Thanks
Simone

Hi Simone,
you are really in a bit of bad luck.

After Sydney foss4g now we had the GFOSS in Italy, so answering has been hard.

> if it is possible I'd like to stay with the version 1.1 of Udig.

You can, but I can't help you. I didn't have a look at rasters in that version.

> is it true?

Nope, the only thing you would get is a pile of errors. The thing that
signed the 1.1 - 1.2 migration, has been the geotools migration from
more or less a 2.2 to the geotools trunk.

> it is possible to do or it is preferable to pass to the version 1.2?

If you want fast support here, I am afraid you should migrate. There
are some people that are working on coverages in the new uDig version.

Ciao
