Class DefaultImageGenerator

java.lang.Object
  com.mebigfatguy.polycasso.DefaultImageGenerator

All Implemented Interfaces:

ImageGenerator, java.lang.Runnable

public class DefaultImageGenerator
extends java.lang.Object
implements ImageGenerator, java.lang.Runnable

class that generates test images iteratively looking for the best image that matches a target. The images are generated from semi-transparent polygons that are improved upon over time. This class generates multiple images in parallel to keep multicore processors busy.

Constructor Summary

DefaultImageGenerator(Settings confSettings, java.awt.Image image, java.awt.Dimension size)
creates an ImageGenerator for the given target image, and size

Method Summary

void	addImageGeneratedListener(ImageGeneratedListener listener) allows interested parties to register to receive events when a new best image has been found.
void	complete() completes the image by transforming the polygon image to the real image
void	fireImageGenerated(java.awt.Image image) informs all listeners that a new best image has been found
PolygonData[]	getBestData() retrieves the best set of polygons for drawing the image so far
java.awt.Dimension	getImageSize() returns the image size that is being generated.
java.awt.image.BufferedImage	getTargetImage() retrieves the scaled target iamge
void	removeImageGeneratedListener(ImageGeneratedListener listener) allows uninterested parties to unregister to receive events when a new best image is found
void	run() the runnable interface implementation to repeatedly improve upon the image and check to see if it is closer to the target image.
void	startGenerating() starts up threads to start looking for images that are closest to the target
void	stopGenerating() shuts down threads that were looking for images

Constructor Detail

DefaultImageGenerator

public DefaultImageGenerator(Settings confSettings,
                             java.awt.Image image,
                             java.awt.Dimension size)

creates an ImageGenerator for the given target image, and size

Parameters:

confSettings - the configuration settings

image - the target image

size - the dimension of the image

Method Detail

getTargetImage

public java.awt.image.BufferedImage getTargetImage()

retrieves the scaled target iamge

Specified by:

getTargetImage in interface ImageGenerator

Returns:

the target image

getImageSize

public java.awt.Dimension getImageSize()

returns the image size that is being generated. This size might be different the original image if the size is bigger then the max setting.

Specified by:

getImageSize in interface ImageGenerator

Returns:

the image size

addImageGeneratedListener

public void addImageGeneratedListener(ImageGeneratedListener listener)

allows interested parties to register to receive events when a new best image has been found.

Specified by:

addImageGeneratedListener in interface ImageGenerator

Parameters:

listener - the listener that is interested in events

removeImageGeneratedListener

public void removeImageGeneratedListener(ImageGeneratedListener listener)

allows uninterested parties to unregister to receive events when a new best image is found

Specified by:

removeImageGeneratedListener in interface ImageGenerator

Parameters:

listener - the listener that is no longer needed

fireImageGenerated

public void fireImageGenerated(java.awt.Image image)

informs all listeners that a new best image has been found

Specified by:

fireImageGenerated in interface ImageGenerator

Parameters:

image - the new best image

startGenerating

public void startGenerating()

starts up threads to start looking for images that are closest to the target

Specified by:

startGenerating in interface ImageGenerator

stopGenerating

public void stopGenerating()

shuts down threads that were looking for images

Specified by:

stopGenerating in interface ImageGenerator

complete

public void complete()

completes the image by transforming the polygon image to the real image

Specified by:

complete in interface ImageGenerator

getBestData

public PolygonData[] getBestData()

retrieves the best set of polygons for drawing the image so far

Specified by:

getBestData in interface ImageGenerator

Returns:

the best set of polygons

run

public void run()

the runnable interface implementation to repeatedly improve upon the image and check to see if it is closer to the target image. Images are created in batches of settings.numCompetingImages and the best one (if better than the parent) is selected as the new best.

Specified by:

run in interface java.lang.Runnable
