[udig-users] response: add GeoTifff Image

[Alberto Debiasi <debiasi.alberto@xxxxxxxxx>]

I tried with the two solutions but nothing works:

1 Solution:
I'm only new to this so forgive me if I'm barking up the wrong tree, I
was digging around in the CatalogPlugin plugin and think that's what
you're looking for.

You can manually create your service and add it to the catalog like so.

IServiceFactory serviceFactory =
CatalogPlugin.getDefault().

getServiceFactory();
IService service = serviceFactory.createService(new URL("file://"+path
<file://%22+path/> ));

try {
   IServiceInfo info = service.getInfo( null );  // try connecting to
make sure the service works

   if (info != null) {
        CatalogPlugin.getDefault().getLocalCatalog().add( service ); //
add service
   }
}catch (IOException couldNotConnect ){
    service.dispose(new NullProgressMonitor());
}


serviceFactory.createService returns List<IService> and not IService.

And if I write :

          List<IService> services = serviceFactory.createService(url);
          IService service=services.iterator().next();

 I have an exception.





2 solution.
However the catalog provides the acquire method that will do all the
work for you.

IService service =
CatalogPlugin.getDefault().getLocalCatalog().acquire(new
URL("file://"+path <file://"+path> ), new NullProgressMonitor());

Simply call this from your menu contribution and provide the path to
your GeoTiff.

One thing to note is that the acquire method douse not guarantee that a
geotiff service will be used to render your layer. If it I important
that your layer use a geotiff render you will have to use the manual
service creation method.


the class ICatalog doesnt' have the method acquire.
I tried with:

ICatalog icatalog =CatalogPlugin.getDefault().getLocalCatalog();
                        icatalog.find(url, new NullProgressMonitor());

icatalog.findService(new URL("file://"+selPath));

but nothing append....I don't see the geotiff image inside the 2d map....

       Hi,
       I wuold like to add a geoTiff image on a 2D map simply pressing
a button.

       The functionality is the same as "right click on a map" -> "add
files" -> "and select a GeoTiff image"
       but I don't know which classes I should use and in which way.

       Thanks.
