Constructor Detail

AbstractArc

protected AbstractArc(int id,
           int version,
           Rectangle bounds,
           Point start,
           Point end)

Method Detail

write

public void write(int tagID,
         EMFOutputStream emf)
           throws IOException

Description copied from class: EMFTag

Writes the extra tag information to the outputstream in binary format. This implementation writes nothing, but concrete tags may override this method. This method is called just after the TagHeader is written.

Overrides:

write in class EMFTag

Parameters:

tagID - id of the tag

emf - Binary CGM output stream

Throws:

IOException - thrown by EMFOutputStream

toString

public String toString()

Overrides:

toString in class EMFTag

Returns:

a description of the tagName and tagID

getShape

protected Shape getShape(EMFRenderer renderer,
             int arcType)

creates a shape based on bounds, start and end

Parameters:

renderer - EMFRenderer storing the drawing session data

arcType - type of arc, e.g. Arc2D.OPEN

Returns:

shape to render
