[Gvsig_english] Loading data using vector file

[Jorge Sanz]

Hi Luca

Not directly, you should develop an extension (maybe using the scripting API) to get the path to the raster file from the attributes table and creating a new layer from that file (FLyrRaster) and after that loading it to the view.

In the scripting manual you have some of this features with samples, maybe loading a raster file is not present but it's quite simple if you have the source file path. 

In java you should do something like that (quite rude code, without checkings and so on) after you get the file path and create the "myRasterFile" object:

/*create raster layer from file*/
RasterAdapter adapter = new RasterFileAdapter(myRasterFile);
Driver d = LayerFactory.getDM().getDriver("gvSIG Image Driver");
adapter.setDriver(d);
Flayer layer = new FLyrRaster();
((FLyrRaster) layer).setSource(adapter);

/*load flayer into current view*/
IWindow iwin = PluginServices.getMDIManager().getActiveWindow();
MapContext mapcontext = ((View) iwin).getMapControl()
							.getMapContext();
mapcontext.getLayers().addLayer(layer);


Not sure if all code is correct (not tested as a whole, cut and pasted from different places), maybe other smarter developers can add some comments or corrections.

Hope it helps

Asunto: [Gvsig_english] Loading data using vector file

Hello everybody!

I am trying to find a good way for doing this task..any help is appreciate:

I have a polygon vector file that for each area, has got in the attribute table, the name of the Image Raster Data
covering that surface. Is there any way for loading that raster clicking on the polygon?

Thanks
