No, that is not going to work. The screenshot plug-in simply has no way to get the cursor image set by other applications. X11 doesn't provide an API for this. At least not as far as I know.

Did I say something wrong? You can only access your own cursor that way (that of the screenshot plug-in). The point of a screenshot application is though to grab screenshots of other applications. gdk_cursor_get_image() won't work for that. Did you check if kscreenshot does actually show the correct cursor? I suspect what they are doing is to simply paste a default cursor image on the screenshot. You can already do that easily in GIMP after you have taken the screenshot.

I think I already pointed you to the API reference for GimpRGB and gimp_rgb_set_uchar() in particular. GimpChannelOps is an enum and the possible values are listed in the API reference. Just follow the link. You can also save yourself the hassle of working with pixel regions if all you want to do is to get the color of a single pixel.

Ok, I'll modify the plugin in this way:

gint width, height; //dell'immagine su cui va applicato il plugin
gint altezza, larghezza; //numero di pixel formanti la palette

}
for(i = 0; i < 3; i++) {

}

//si distruggono i parametri per liberare la memoria
gimp_destroy_params (return_vals, nreturn_vals);
if(success) g_print("Fatto\n");
}
the variable success is TRUE after calling the procedure but it select every
black pixel instead the values contained in the "colori" vector. It' is a bug
or I'm make some mistakes?

Re: [Gimp-developer] calling a procedure in a plugin
gimp_run_procedure() is not properly terminated with GIMP_PDB_END (see
documentation). Again, as Sven said, use c wrappers if they are
available for procedure that you need.
