Method Detail

paint

public void paint(Graphics2D g2d)

Description copied from interface: FXTool

Invoked by FXCanvas to draw tool.

Specified by:

paint in interface FXTool

Overrides:

paint in class AbstractTool

Parameters:

g2d - the Graphics2D context in which to paint

startTool

public void startTool(FXCanvas canvas)

Description copied from class: AbstractTool

Overidden to register input listener. Inherited tool please do not forget to call super

Specified by:

startTool in interface FXTool

Overrides:

startTool in class AbstractTool

createArea

protected Area createArea()

mouseClicked

public void mouseClicked(MouseEvent evt)

Specified by:

mouseClicked in interface MouseListener

Overrides:

mouseClicked in class AbstractTool

mousePressed

public void mousePressed(MouseEvent evt)

Specified by:

mousePressed in interface MouseListener

Overrides:

mousePressed in class AbstractTool

mouseDragged

public void mouseDragged(MouseEvent evt)

Specified by:

mouseDragged in interface MouseMotionListener

Overrides:

mouseDragged in class AbstractTool

mouseReleased

public void mouseReleased(MouseEvent evt)

Specified by:

mouseReleased in interface MouseListener

Overrides:

mouseReleased in class AbstractTool

updateArea

protected void updateArea()

createResizeTransform

protected AffineTransform createResizeTransform(AffineTransform at)

Create Resize transform into "return value" at and return at. If at is null a new AffineTransform is allocated. This is useful if the caller wants to avoid allocating a new AffineTransform object on the heap.

Returns:

if at is null return a newly created AffineTransform

createMoveTransform

protected AffineTransform createMoveTransform(AffineTransform at)

Create Move Transform into "return value" at and return at. If at is null a new AffineTransform is allocated. This is useful if the caller wants to avoid allocating a new AffineTransform object on the heap.

Returns:

if at is null return a newly created AffineTransform

cropAreaContains

protected boolean cropAreaContains(Point2D point,
                                   boolean needTransform)

Check whether the supplied point is inside Crop Area

Parameters:

point - Point2D to check

needTransform - if true transfrom the supplied point into cropArea space

Returns:

true or false
