Field Detail

PROPERTY_IMAGE

public static final String PROPERTY_IMAGE

The property name that identifies a change of this node's image (see getImage). Both old and new value will be set correctly to Image objects in any property change event.

PROPERTY_CODE_IMAGE

public static final int PROPERTY_CODE_IMAGE

The property code that identifies a change of this node's image (see getImage). Both old and new value will be set correctly to Image objects in any property change event.

Constructor Detail

PImage

public PImage()

Constructs a PImage without a java.awt.Image attached.

PImage

public PImage(String fileName)

Construct a new PImage by loading the given fileName and wrapping the resulting java.awt.Image.

Parameters:

fileName - of the image to wrap

PImage

public PImage(Image image)

Construct a new PImage wrapping the given java.awt.Image.

Parameters:

image - image that this PImage will wrap

PImage

public PImage(URL url)

Construct a new PImage by loading the given url and wrapping the resulting java.awt.Image. If the url is null, create an empty PImage; this behaviour is useful when fetching resources that may be missing.

Parameters:

url - URL of image resource to load

Method Detail

getImage

public Image getImage()

Returns the image that is shown by this node, or null if none.

Returns:

java.awt.Image being wrapped by this node

setImage

public void setImage(String fileName)

Set the image that is wrapped by this PImage node. This method will also load the image using a MediaTracker before returning.

Parameters:

fileName - file to be wrapped by this PImage

setImage

public void setImage(Image newImage)

Set the image that is wrapped by this PImage node. This method will also load the image using a MediaTracker before returning.

Parameters:

newImage - image to be displayed by this PImage

paint

protected void paint(PPaintContext paintContext)

Renders the wrapped Image, stretching it appropriately if the bounds of this PImage doesn't match the bounds of the image.

Overrides:

paint in class PNode

Parameters:

paintContext - context into which the rendering will occur

toBufferedImage

public static BufferedImage toBufferedImage(Image image,
                            boolean alwaysCreateCopy)

Converts the provided image into a BufferedImage. If alwaysCreateCopy is false then if the image is already a buffered image it will not be copied and instead the original image will just be returned.

Parameters:

image - the image to be converted

alwaysCreateCopy - if true, will create a copy even if image is already a BufferedImage

Returns:

a BufferedImage equivalent to the Image provided
