Method Summary

void	addListener(IPictureListener l) adds the given IPictureListener
void	fill(int value) fills the entire buffer data with the given 32 bit value
private void	firePictureChanged() fires a picture changed notify
int[]	getData() returns a reference to the internal 32 bit buffer
int	getHeight() returns the picture height
java.awt.Image	getImage() produces a image from the internal 32 bit buffer
int	getWidth() returns the picture width
boolean	isValid() returns the images state, false if no or a corrupted image was loaded, true if valid picture data is stored in the picture.
void	loadImage(java.lang.String fileName) loads a image from file, gif or jpg, java std ;-)
void	process(IPictureProcessor processor) uses the given processor to process the image data.
void	redoPicture()
void	removeListener(IPictureListener l) removes the given IPictureListener
void	reset() resets the image
void	saveImage(java.lang.String fileName) save a image as Windows Bitmap
void	setData(int[] data, int width, int height) sets the picture data directly. the width and height must match the buffers length!
void	setDimension(int width, int height) allocates memory for a picture of the given width and height.
void	undoPicture()
