Provides low-level operations for painting and editing on an ILcdGXYView.
See ALcdGXYPen.create(com.luciad.model.ILcdModelReference) for default factory methods.
Objects to be painted or manipulated are typically specified in model coordinates. These coordinates are transformed to world coordinates and AWT view coordinates, e.g for painting or picking. Therefore, the ILcdGXYPen saves you a lot of work and helps you to write code which is easier to understand and maintain.
An ILcdGXYPen maintains a current position which is used by several methods. It also provides a convenient way to transform between model, world and AWT coordinates. Related methods are:
An ILcdGXYPen stores an internal path which can be accumulated and painted. The path is accumulated by appending lines, point lists, or arcs. Subsequently, it can then be painted as a polyline, a polygon, or a filled polygon. Related methods are:
Alternatively, an ILcdGXYPen allows to construct an external AWT path which the user can modify, transform, or paint as required. Related methods are:
Similarly, lines, point lists, or arcs can be appended to an external general path which the user can modify, transform or paint as required. Related methods are:
An ILcdGXYPen also provides a set of methods to paint elementary shapes such as lines and arcs. Related methods are:
Furthermore, information can be obtained about the geometry of elementary shapes, such as distances and bounding boxes in AWT coordinates. Related methods are:
An ILcdGXYPen also provides assistance with picking objects. Related methods are:
Finally, an ILcdGXYPen allows the user to specify and paint hot points. Related methods are:
