drawImageImpl

protected void drawImageImpl(Image image,
                             int x,
                             int y)

Overrides graphics call to use image observer.

Overrides:

drawImageImpl in class mxGraphics2DCanvas

getImageSize

protected Dimension getImageSize(Image image)

Returns the size for the given image.

Overrides:

contains

public boolean contains(mxGraphComponent graphComponent,
                        Rectangle rect,
                        mxCellState state)

intersects

public boolean intersects(mxGraphComponent graphComponent,
                          Rectangle rect,
                          mxCellState state)

hitSwimlaneContent

public boolean hitSwimlaneContent(mxGraphComponent graphComponent,
                                  mxCellState swimlane,
                                  int x,
                                  int y)

Returns true if the given point is inside the content area of the given swimlane. (The content area of swimlanes is transparent to events.) This implementation does not check if the given state is a swimlane, it is assumed that the caller has checked this before using this method.
