getWorldBounds

public java.awt.geom.Rectangle2D getWorldBounds()

autoScale

public void autoScale()

Sets the world2screen mapping so that all objects displayed within the canvas are completely visible on the drawing board (provided their getWorldBoundingBox method is implemented properly).

autoScale

public void autoScale(boolean keepAR)

Sets the world2screen mapping so that all objects displayed within the canvas are completely visible on the drawing board (provided their getWorldBoundingBox method is implemented properly).

Parameters:

keepAR - autoScale but keep aspect ratio

componentResized

public void componentResized(java.awt.event.ComponentEvent e)

rescale

public void rescale()

Rescales the world area displayed by the canvas according to the prior autoScale() call. (This method will have no effect, until autoscaling has been invoked).
