com.bbn.openmap.omGraphics.OMGraphic
Used to be the base class of OpenMap graphics, but now inherits from BasicGeometry, which now contains all the information about the geometry of the OMGraphic. The OMGraphic also contains information about how the geometry should be drawn.
The OMGraphics are raster and vector graphic objects that know how to position and render themselves on a given x-y window or lat-lon map projection. All you have to do is supply the location data (x/y, lat/lon) and drawing information (color, line width) and the graphic handles the rest.
This class contains parameters that are common to most types of graphics. If a parameter doesn't make sense for a particular graphic type, it is ignored.
The OMGraphics are being updated to be able to provide java.awt.Shape representations of themselves after they have been generated(). The getShape() method returns a java.awt.Shape object. With the Shape object, you can do some spatial analysis (object operations) on the projected OMGraphics. NOTES:
- Color values cannot be set to null, but can be set to OMGraphic.clear. Actually, if you set them to null, they will set themselves to be clear.
- XY Rendering: Java specifies that the origin is the top left of the window, x increases to the right, y increases down.
- LatLon Rendering: Defined by the Projection object. The center of the window usually corresponds to the center of the projection. OMGraphics should project themselves using the appropriate forward() method listed in the Projection interface
- Offset Rendering: same as XY, but with origin set to a projected LatLon point.
