public class MeasuredImage
extends java.lang.Object
implements Measurable

MeasuredImage contains an image and a scale in world units. When a MeasuredImage is added to a drawing panel, the image will scale itself to the panel's world units.

Method Detail

setImage

public void setImage(java.awt.image.BufferedImage _image)

getImage

public java.awt.image.BufferedImage getImage()

setVisible

public void setVisible(boolean isVisible)

Sets the visibility of the lattice. Drawing will be disabled if visible is false.

Parameters:

isVisible -

draw

public void draw(DrawingPanel panel,
                 java.awt.Graphics g)

Draws the image on the panel.

Specified by:

draw in interface Drawable

Parameters:

panel -

g -

isMeasured

public boolean isMeasured()

Description copied from interface: Measurable

Determines if information is available to set min/max values. Objects that store data should return false if data is null.

Specified by:

isMeasured in interface Measurable

Returns:

true if min/max values are valid

getXMin

public double getXMin()

Description copied from interface: Measurable

Gets the minimum x needed to draw this object.

Specified by:

getXMin in interface Measurable

Returns:

minimum

getXMax

public double getXMax()

Description copied from interface: Measurable

Gets the maximum x needed to draw this object.

Specified by:

getXMax in interface Measurable

Returns:

maximum

getYMin

public double getYMin()

Description copied from interface: Measurable

Gets the minimum y needed to draw this object.

Specified by:

getYMin in interface Measurable

Returns:

minimum

getYMax

public double getYMax()

Description copied from interface: Measurable

Gets the maximum y needed to draw this object.

Specified by:

getYMax in interface Measurable

Returns:

minimum

setXMin

public void setXMin(double _xmin)

setXMax

public void setXMax(double _xmax)

setYMin

public void setYMin(double _ymin)

setYMax

public void setYMax(double _ymax)

setMinMax

public void setMinMax(double _xmin,
                      double _xmax,
