nice!

Do you want write access to the svn?
Then I would need you to register at sourceforge and you send me your 
name there (can be also in personal communication - even in german ;)

Hi all, in the same way that load a layer by code, I needed load a jpg image by 
code, at the same map.
I want to share with you too, the code to load an image without a wizard:

***
***
public boolean execute(PlugInContext context) throws Exception
{
LayerManager layerManager = context.getWorkbenchContext().getLayerManager();
layerManager.setFiringEvents(false);
File file = new File("c://image.jpg");
Layer lyr = createLayer(layerManager, file);
layerManager.setFiringEvents(true);
Category category = 
TaskUtil.getSelectedCategoryName(context.getWorkbenchContext());
category.add(0, (Layerable) lyr);
ReferencedImageFactory imageFactory= new GraphicImageFactory(); //depends the 
image type
Feature feature = createFeature(imageFactory, file, 
getImageryLayerDataset(lyr));
lyr.getFeatureCollectionWrapper().add(feature);
}

private Feature createFeature(ReferencedImageFactory referencedImageFactory,
File file, ImageryLayerDataset imageryLayerDataset) 
{
Feature feature = new BasicFeature(ImageryLayerDataset.getSchema());
feature.setAttribute(ImageryLayerDataset.ATTR_FILE, file.getPath());
feature.setAttribute(ImageryLayerDataset.ATTR_FORMAT,
referencedImageFactory.getTypeName());
feature.setAttribute(ImageryLayerDataset.ATTR_FACTORY,
referencedImageFactory.getClass().getName());
feature.setGeometry(new GeometryFactory().createPoint((Coordinate)null));
imageryLayerDataset.createImage(feature);
return feature;
}

private ImageryLayerDataset 
getImageryLayerDataset(com.vividsolutions.jump.workbench.model.Layer layer) 
{
ReferencedImageStyle irs = 
(ReferencedImageStyle)layer.getStyle(ReferencedImageStyle.class);
return irs.getImageryLayerDataset();
}
***

Note: in my proyect i have a xml map with layers and images paths, all them

2010-05-28 Thread Benjamin Gudehus

I should not forget to take a look at DataSourceFileLayerLoader which
already provides a similar functionality.

But it needs to split up in serveral independent methods. i.e. split
DataSourceFileLayerLoader.open() into toDataSourceQuery(),
toFeatureCollection() and toLayer().

  yes, important to make no backward incompatible changes to

 First step is to extract dataset loading with DataSource from
 LoadDatasetPlugIn into a
 new class called DataSourceTools (or so) in org.openjump.core.apitools.

dataSourceClass,
CoordinateSystem coordinateSystem)
static FeatureCollection toFeatureCollection(DataSourceQuery
dataSourceQuery)
static DataSource toDataSource(Class dataSourceClass)

}

class InternalLoadDatasetPlugIn extends AbstractPlugIn {

Thanks for the help guys!   I`ve solved it by the following code:
(maybe there are some things no needed, like options, but it works!!)


DataSource dataSource = 
(DataSource)LangUtil.newInstance(StandardReaderWriterFileDataSource.Shapefile.class);
Map options = new HashMap();
Map properties = new HashMap();
properties.put(DataSource.FILE_KEY, "c://roads.shp");
properties.putAll(options);
dataSource.setProperties(properties);

DataSourceQuery dataSourceQuery = new DataSourceQuery(dataSource, null, 
"roads");
ArrayList exceptions = new ArrayList();
String layerName = dataSourceQuery.toString();

Connection connection = dataSourceQuery.getDataSource().getConnection();
   try 
{
  FeatureCollection dataset = 
dataSourceQuery.getDataSource().installCoordinateSystem(
 connection.executeQuery(dataSourceQuery.getQuery(), exceptions, null),
  
CoordinateSystemRegistry.instance(context.getWorkbenchContext().getBlackboard()));
  if (dataset != null) 
  { 
LayerManager layerManager = 
context.getWorkbenchContext().getLayerManager();
Layer layer = new Layer(layerName, 
layerManager.generateLayerFillColor(), dataset, layerManager);
layerManager.addLayerable("categoryName", (Layerable) layer);
layer.setDataSourceQuery(dataSourceQuery);
layer.setFeatureCollectionModified(false);
layer.setVisible(true);
  }
} finally {
connection.close();

Hei Benjamin,

how about not splitting the class (i.e. avoiding to break anything), but 
just add the second class for programmatical access? Maybe this could 
even go into the core.apitools package.

If you feel like creating such a class, I can add it.

Re: [JPP-Devel] How to load ESRI shapefiles by code

2010-05-27 Thread Michaël Michaud

Hi,

Don't know if you still want to work inside OpenJUMP  wokbench or not, 
but here is a very simple example I just picked up from the JTS 
discussion list :

String layer = "data/tigerline/2009_us_state/tl_2009_us_state.shp";
ShapefileReader reader = new ShapefileReader();
FeatureCollection fc = reader.read(new DriverProperties(layer));
List fs = fc.getFeatures();

Is that what you're looking for ?

Re: [JPP-Devel] How to load ESRI shapefiles by code

2010-05-27 Thread Benjamin Gudehus

Hi!

If you just want to load shapefiles, you can use ShapefileReader directly to
load a shapefile into a FeatureCollection.

ShapefileReader reader = new ShapefileReader();
FeatureCollection features = reader.read(new
DriverProperties(shapefilePath));
Layer layer = context.getLayerManager().addLayer("Category Name", "Layer
Name", features);

DataSourceQuery: The monitor parameter is a TaskMonitor and used to report
progress and check cancel requests. Connection needs this TaskMonitor, so
you need to put the call into the run() method in the (threaded) PlugIn to
receive a monitor (public void run(TaskMonitor monitor, PlugInContext
context)).

If you don't want to use the run() / ThreadedPlugIn, you could maybe create
a com.vividsolutions.jump.task.DummyTaskMonitor and use it monitor instead?
(I didn't test this)

connection = dataSourceQuery.getDataSource().getConnection()
connection.executeQuery(query, exceptions, new DummyTaskMonitor())

--

BTW: Maybe we should split LoadDatasetPlugIn into two PlugIns (I had this
idea a few weeks ago).

One called LoadDatasetPlugIn without dialog, which loads datasets into the
LayerManager.

LoadDatasetPlugIn datasetPlugIn = new LoadDatasetPlugIn();
datasetPlugIn.setFilepath("~/shapefiles/world.shp");
datasetPlugIn.setType("shapefile");
datasetPlugIn.setCategory("Category Name");
datasetPlugIn.setLayerName("Layer Name");
datasetPlugIn.execute();

Another called LoadDatasetsDialogPlugIn with a dialog, which shows a
JFileChooser and uses the LoadDatasetPlugIn.

With LoadDatasetPlugIn one can programmatically load datasets.
LoadDatasetsDialogPlugIn is used in the workbench (File > Open...).

Greetings from rainy Hanover.

does it help you too look into this class:

com.vividsolutions.jump.workbench.datasource.AbstractLoadDatasetPlugIn

I think it is not used anymore...
