Hi all,
I am also having trouble generating an image. I tried to run the following
code:
Style shpStyle = SLD.createPolygonStyle(Color.YELLOW, null, 0.0f);
FileDataStore dataStore = FileDataStoreFinder.getDataStore(new
File("/home/odilon/mapas/AESA/Municipios/Municipios.shp"));
SimpleFeatureSource shapefileSource =
dataStore.getFeatureSource();
final MapContext map = new DefaultMapContext();
ReferencedEnvelope envelope = new ReferencedEnvelope(0.0, 300.0,
0.0, 600.0, null);
map.setAreaOfInterest(envelope);
map.addLayer(shapefileSource, shpStyle);
saveImage(map, "/home/odilon/image.jpg");
Where the saveImage method is the same of the
example<http://docs.geotools.org/latest/userguide/library/render/gtrenderer.html#image>and
as result I got a blank image.
Thanks in advance.
