Class PiImageSource

java.lang.Object

jv.object.PsObject

jvx.imageDisplay.PiImageSource

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, PsUpdateIf

public abstract class PiImageSource
extends PsObject

Abstract class for images computed from a function over the xy-plane. The image should be considered as lying above a rectangular region of the xy-plane. The pixel images are assigned by subclasses based on the function values.

Method Detail

init

public void init()

Initialization.

Overrides:

init in class PsObject

update

public boolean update(java.lang.Object event)

Update the class whenever a child has changed. Method is usually invoked from the children.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PsObject

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false

PsObject.setParent(PsUpdateIf), PsObject.getFather(), PsObject.addUpdateListener(PsUpdateIf)

getImage

public java.awt.Image getImage()

Get image of this object, will automatically be updated whenever computeColors() is called.

createImage

public java.awt.Image createImage(java.awt.Component comp,
                                  int width,
                                  int height)

Set size of image and, if changed, create an new image.

compute

public abstract void compute()

Compute an image in the complex plane and update the corresponding images.

computeColors

public void computeColors()

Compute colors based on a previously computed function values.

getImagePosition

public int getImagePosition(double u,
                            double v)

Converts a point (u,v) in the plane to its position in the image.

Parameters:

u - real value of complex position

v - imaginary value of complex position

Returns:

index in the pixel array

getDomainPosition

public PdVector getDomainPosition(java.awt.Point loc)

Converts a point (u,v) in the complex plane to its position in the image.

Parameters:

loc - Integer location in image

Returns:

2d double coordinates of location in domain of image.

getDomainBounds

public PdVector getDomainBounds()

Set the domain of the image in the Euclidean plane.

Parameters determine a rectangle in the complex plane in which the Mandelbrot set is computed.

setDomainBounds

public void setDomainBounds(PdVector bounds)

Set the domain of the image in the Euclidean plane.

Parameters determine a rectangle in the complex plane in which the Mandelbrot set is computed.

setDomainBounds

public void setDomainBounds(double[] bounds)

Set the domain of the image in the Euclidean plane.

Parameters determine a rectangle in the complex plane in which the Mandelbrot set is computed.

setDomainBounds

public void setDomainBounds(double xMin,
                            double yMin,
                            double xMax,
                            double yMax)

Set the domain of the image in the Euclidean plane.

Parameters determine a rectangle in the complex plane in which the Mandelbrot set is computed.

getBlockSize

public int getBlockSize()

Get block size of image which determines a square block of equally rendered pixels. Block size 1 means every pixel is computed (default), which larger values will lead to pixelization effects while speeding up calculations.

setBlockSize

public void setBlockSize(int blockSize)

Set block size of image which determines a square block of equally rendered pixels. Block size 1 means every pixel is computed (default), which larger values will lead to pixelization effects while speeding up calculations.
