| Method Summary |
|
| public IAbstractContext | copy()
Makes a deep copy of this object, if necessary.
This is an alternative to clone since I hate clone, it is too hard to implement.
a new copy of this object. |
| ReferencedEnvelope | getBoundingBox(Point screenLocation, int scalefactor)
Returns a world bounding box the scalefactor * (size of a pixel) at the location
corresponding to the point on the screen. |
| CoordinateReferenceSystem | getCRS()
CoordinateReferenceSystem of the map. |
| IEditManager | getEditManager()
The map's edit manager. |
| FeatureCollection | getFeaturesInBbox(ILayer layer, Envelope bbox)
Returns all the features that intersect with the bounding box.
Parameters:
source - The featuresource to get features from.
Parameters:
bbox - The bounding box that acts as a filter. |
| IMap | getMap()
The context's map. |
| IMapDisplay | getMapDisplay()
The map's display object. |
| List<ILayer> | getMapLayers()
Returns the list of layers in the current map. |
| Envelope | getPixelBoundingBox(Point screenLocation)
Returns a world bounding box the size of a pixel at the location corresponding to the point
on the screen. |
| Coordinate | getPixelSize()
Returns the size of a pixel in world units. |
| IProject | getProject()
The map's containing Project. |
| IRenderManager | getRenderManager()
The map's render manager
Convenience for getMap().getRenderManager(). |
| public ILayer | getSelectedLayer()
|
| IViewportModel | getViewportModel()
The map's viewport model. |
| Coordinate | pixelToWorld(int x, int y)
Converts a coordinate expressed on the device space back to real world coordinates A
convenience method. |
| Shape | toShape(ReferencedEnvelope envelope)
Transform the provided envelope to a java 2d shape (in screen coordiantes). |
| Shape | toShape(Geometry geometry, CoordinateReferenceSystem crs)
Transform the provided geometry to a java 2d shape (in screen coordiantes). |
| Point | tranformCoordinate(Envelope bbox, Dimension displaySize, Coordinate coordinate)
Transforms the coordinate from the bounding box (bbox) to the area defined by the rectangle it starts at 0,0. |
| public ReferencedEnvelope | worldBounds(Rectangle rectangle)
Creates an Envelope that is close, error to slightly larger, to the Rectangle when it is
transformed into world coordinates. |
| Point | worldToPixel(Coordinate coord)
Returns the pixel on the screen for a given coordinate in world space. |
| public MathTransform2D | worldToScreenMathTransform()
Creates a MathTransform that will transform from the screen CRS to the world CRS. |
| AffineTransform | worldToScreenTransform()
Gets up the affine transform that will transform from the world to screen. |
