Re: [Geotools-gt2-users] Transforming incoming layers
So i tried it with Swing and Quickstart and it works fine with Shapefiles.
With WMSLayer on the other hand, i can't get it to work, even with Swing.
For some reason i need the line
mapcontent.getViewport.setBounds(displaylayer.getBounds()), so the WMSLayer
is rendered without exceptions. Without it, the CRS doesn't change, but
also the WMSLayer isn't displayed, and it crashes after clicking zoom
extent.
If you would be so kind, and have a look at this, maybe you can tell me how
to be able to render the wmslayer without changing the CRS, which i assume
setting the bounds of the viewport to the layerbounds does.
public class WMSLab extends JFrame {
public static void main(String[] args) throws Exception {
WebMapServer wms = new WebMapServer(new URL("
https://sgx.geodatenzentrum.de/wms_clc5_2018;));
List wmsLayers = WMSLayerChooser.showSelectLayer(wms);
if (wmsLayers == null) {
JOptionPane.showMessageDialog(null, "Could not connect - check
url");
System.exit(0);
}
MapContent mapContent = new MapContent();
mapContent.setTitle(wms.getCapabilities().getService().getTitle());
mapContent.getViewport().setCoordinateReferenceSystem(DefaultGeographicCRS.WGS84);
System.out.println("before adding layer " +
mapcontent.getViewport().getCoordinateReferenceSystem());
for (Layer wmsLayer : wmsLayers) {
WMSLayer displayLayer = new WMSLayer(wms, wmsLayer);
mapContent.addLayer(displayLayer);
//try with and without this line
mapContent.getViewport().setBounds(displayLayer.getBounds());
}
System.out.println("after adding layer " +
mapcontent.getViewport().getCoordinateReferenceSystem());
JMapFrame.showMap(mapContent);
}
}

So i also tried mapPane.setCrs(CRS.decode("EPSG:4326"))
and
mapContent.getViewport().setCoordinateReferenceSystem(CRS.decode("EPSG:4326")),
which both change the CRS you get by
calling mapContent.getCoordinateReferenceSystem(), but as soon as the first
layer comes, it overwrites it with it's own (EPSG:23700)

The quickstart is with the swing module, right? I'm using SWT, so maybe
there is the problem. Thanks for your help so far. Have to look into that.

Re: [Geotools-gt2-users] Transforming incoming layers
I've just experimented with adding the line
map.getViewport().setCoordinateReferenceSystem(DefaultGeographicCRS.WGS84);
at line 53 of the GeoTools quickstart and opening a shapefile in
EPSG:27700, the map is displayed in EPSG:4326 when the display is made
visible.

Re: [Geotools-gt2-users] Transforming incoming layers
Now i set the viewport to be non-editable, which finally results in the CRS
staying epsg:4326, but also results in the WMSLayer not being able to
render with this exception:

Re: [Geotools-gt2-users] Transforming incoming layers
I usually use something like map.getViewport().setCoordinateReferenceSystem(DefaultGeographicCRS.WGS84); Looking at JCRSPopupMenu shows that they use mapPane.getMapContent().getViewport().setCoordinateReferenceSystem(newCRS); which I suspect boils down to the same thing.
