List of mapToLayerTransform() Examples

Examples of mapToLayerTransform()

org.locationtech.udig.project.ILayer.mapToLayerTransform()
Returns the Mathtransform from the map's CRS (modeled as part of the viewport model) to this layers CRS .
getMap().getViewportModel() will return the ViewportModel.
@see org.locationtech.udig.project.render.IViewportModel

Examples of org.locationtech.udig.project.ILayer.mapToLayerTransform()

            // CRS obtained from the ViewportModel
            Coordinate world = getContext().pixelToWorld(e.x, e.y);
            
            // now we must transform the coordinate to the CRS of the layer
            ILayer layer = getContext().getSelectedLayer();
            MathTransform tranform = layer.mapToLayerTransform();
            
            double[] from=new double[]{world.x, world.y};
            double[] to = new double[2];
            tranform.transform(from, 0, to, 0, 1);
