Method Detail

extend

double extend(double value)

discretize

int discretize(double value,
             int max)

disposeGraphics

public void disposeGraphics()

addPolygon

public void addPolygon(double[] vals,
              int offset,
              int numVertices)

Adds a polygon with the given colors. ALL double values passed in must be 0.0 ... 1.0. The values are taken starting at vals[offset]. The first four values are colors and alpha. The remaining values are the x and y values of the polygon vertices. You must call graphics.dispose() after you're done with all your polygon-drawing.

clear

public void clear()

Erases the image.

maxError

double maxError()

The maximum possible error between the two images. Will be a value >= 0. By the way, the min error -- what you're shooting for -- is 0

error

public double error()

Computes the sum squared error between the image and the original. This is defined as the sum, for all pixels, and for all three colors in the pixel, of the squared difference between the images with regard to that color on that pixel. Error goes from 0 to 1.

load

public void load(File file)

Loads the original and creates a new blank image to scribble on, and a new graphics object.

display

public void display(String title)

For debugging only.

save

public void save(File file)

Saves the image (not the original) out to a PNG file so you can compare.

writeObject

private void writeObject(ObjectOutputStream out)
                  throws IOException

Throws:

IOException

readObject

private void readObject(ObjectInputStream in)
                 throws IOException,
                        ClassNotFoundException

Throws:

IOException

ClassNotFoundException

clone

public Object clone()

Overrides:

clone in class Object

copyImage

public BufferedImage copyImage(BufferedImage image)
