Field Summary
int	ABORT Production of the image was aborted.
int	ALLBITS An image with a single frame, a static image, is complete.
int	ERROR An error was encountered while producing the image.
int	FRAMEBITS All the pixels needed to draw a complete frame of a multi-frame image are available.
int	HEIGHT The height of the image has been provided as the `height` argument to `imageUpdate`.
int	PROPERTIES The properties of the image have been provided.
int	SOMEBITS More pixels are now available for drawing a scaled variation of the image.
int	WIDTH The width of the image has been provided as the `width` argument to `imageUpdate`.

Method Summary
boolean	imageUpdate(Image image, int flags, int x, int y, int width, int height) This is a callback method for an asynchronous image producer to provide updates on the production of the image as it happens.
