Method Detail

loadImage

void loadImage(java.io.File f)
               throws java.io.IOException

Loads an image from a File. By convention this method is never invoked on the AWT Event Dispatcher Thread.

Throws:

java.io.IOException

loadImage

void loadImage(java.io.InputStream in)
               throws java.io.IOException

Loads an image from an Input Stream. By convention this method is never invoked on the AWT Event Dispatcher Thread.

Throws:

java.io.IOException

getBufferedImage

java.awt.image.BufferedImage getBufferedImage()

Gets the buffered image from the figure.

setBufferedImage

void setBufferedImage(java.awt.image.BufferedImage image)

Sets the buffered image for the figure.

setImage

void setImage(byte[] imageData,
              java.awt.image.BufferedImage bufferedImage)
              throws java.io.IOException

Sets the image.

Parameters:

imageData - The image data. If this is null, a buffered image must be provided.

bufferedImage - An image constructed from the imageData. If this is null, imageData must be provided.

Throws:

java.io.IOException

getImageData

byte[] getImageData()

Gets the image data.

Returns:

imageData The image data, or null, if the ImageHolderFigure does not have an image.
