All Implemented Interfaces:

public class ImagePanel

extends javax.swing.JComponent

ImagePanel. Use ImagePanel to display images. Most advantage of ImagePanel is that it always has thin border around it visible part. This border can be made (half)transparent. It can be used for better handling such things like region selection.

Constructor Detail

ImagePanel

public ImagePanel(java.awt.Image image)

Method Detail

getAlpha

public float getAlpha()

get alpha of ImagePanel's border

Returns:

current alpha value (between 0.0f and 1.0f)

getInsets

public java.awt.Insets getInsets()

Description copied from class: javax.swing.JComponent

If a border has been set on this component, returns the border's insets; otherwise calls super.getInsets.

Returns:

the value of the insets property

See Also:

JComponent.setBorder(javax.swing.border.Border)

getInsets

public java.awt.Insets getInsets(java.awt.Insets insets)

Description copied from class: javax.swing.JComponent

Returns an Insets object containing this component's inset values. The passed-in Insets object will be reused if possible. Calling methods cannot assume that the same object will be returned, however. All existing values within this object are overwritten. If insets is null, this will allocate a new one.

Parameters:

insets - the Insets object, which can be reused

Returns:

the Insets object

See Also:

JComponent.getInsets()

getPreferredSize

public java.awt.Dimension getPreferredSize()

Description copied from class: javax.swing.JComponent

If the preferredSize has been set to a non-null value just returns it. If the UI delegate's getPreferredSize method returns a non null value then return that; otherwise defer to the component's layout manager.

Returns:

the value of the preferredSize property

See Also:

JComponent.setPreferredSize(java.awt.Dimension), ComponentUI

getZoom

public double getZoom()

isUseZoom

public boolean isUseZoom()

main

public static void main(java.lang.String[] args)

paintComponent

public void paintComponent(java.awt.Graphics g)

Description copied from class: javax.swing.JComponent

Calls the UI delegate's paint method, if the UI delegate is non-null. We pass the delegate a copy of the Graphics object to protect the rest of the paint code from irrevocable changes (for example, Graphics.translate).

If you override this in a subclass you should not make permanent changes to the passed in Graphics. For example, you should not alter the clip Rectangle or modify the transform. If you need to do these operations you may find it easier to create a new Graphics from the passed in Graphics and manipulate it. Further, if you do not invoker super's implementation you must honor the opaque property, that is if this component is opaque, you must completely fill in the background in a non-opaque color. If you do not honor the opaque property you will likely see visual artifacts.

Parameters:

g - the Graphics object to protect

JComponent.paint(java.awt.Graphics), ComponentUI

setAlpha

public void setAlpha(float alpha)

set alpha of ImagePanel's border

Parameters:

alpha -

setInsets

public void setInsets(java.awt.Insets insets)

setUseZoom

public void setUseZoom(boolean useZoom)

setZoom

public void setZoom(double zoom)
