All get methods read values from the source image specified at . All set methods write values to the destination image specified at , which may or may not be the same than the source image. This is different than the usual WritableRectIter contract, which read and write values in the same image. This TransfertRectIter is convenient for the implementation of some image operations. since:    2.3 version:    $Id: TransfertRectIter.java 20970 2006-08-11 07:53:22Z jgarnett $ author:    Martin Desruisseaux Method Summary public static  WritableRectIter create(RectIter src, WritableRectIter dst)      Creates a WritableRectIter for the specified source and destination iterator. The two iterators must iterate over a rectangle of the same size, otherwise a RasterFormatException may be thrown during the iteration. Parameters:   src - The source iterator. Parameters:   dst - The destination iterator. public  boolean finishedBands()      Returns true if the max band in the image has been exceeded. public  boolean finishedLines()      Returns true if the bottom row of the bounding rectangle has been passed. public  boolean finishedPixels()      Returns true if the right edge of the bounding rectangle has been passed. public  int[] getPixel(int[] array)      Returns the samples of the current pixel from the image in an array of int. public  float[] getPixel(float[] array)      Returns the samples of the current pixel from the image in an array of float. public  double[] getPixel(double[] array)      Returns the samples of the current pixel from the image in an array of double. public  int getSample()      Returns the current sample as an integer. public  int getSample(int b)      Returns the specified sample of the current pixel as an integer. public  double getSampleDouble()      Returns the current sample as a double. public  double getSampleDouble(int b)      Returns the specified sample of the current pixel as a double. public  float getSampleFloat()      Returns the current sample as a float. public  float getSampleFloat(int b)      Returns the specified sample of the current pixel as a float. public  void jumpLines(int num)      Jumps downward num lines from the current position. public  void jumpPixels(int num)      Jumps rightward num pixels from the current position. public  void nextBand()      Sets the iterator to the next band in the image. public  boolean nextBandDone()      Sets the iterator to the next band in the image, and returns true if the max band has been exceeded. public  void nextLine()      Sets the iterator to the next line of the image. public  boolean nextLineDone()      Sets the iterator to the next line in the image, and returns true if the bottom row of the bounding rectangle has been passed. public  void nextPixel()      Sets the iterator to the next pixel in image (that is, move rightward). public  boolean nextPixelDone()      Sets the iterator to the next pixel in the image (that is, move rightward). public  void setPixel(int[] array)      Sets all samples of the current pixel to a set of int values. public  void setPixel(float[] array)      Sets all samples of the current pixel to a set of float values. public  void setPixel(double[] array)      Sets all samples of the current pixel to a set of double values. public  void setSample(int s)      Sets the current sample to an integral value. public  void setSample(float s)      Sets the current sample to a float value. public  void setSample(double s)      Sets the current sample to a double value. public  void setSample(int b, int s)      Sets the specified sample of the current pixel to an integral value. public  void setSample(int b, float s)      Sets the specified sample of the current pixel to a float value. public  void setSample(int b, double s)      Sets the specified sample of the current pixel to a double value. public  void startBands()      Sets the iterator to the first band of the image. public  void startLines()      Sets the iterator to the first line of its bounding rectangle. public  void startPixels()      Sets the iterator to the leftmost pixel of its bounding rectangle. Method Detail create public static WritableRectIter create(RectIter src, WritableRectIter dst)(Code) Creates a WritableRectIter for the specified source and destination iterator. The two iterators must iterate over a rectangle of the same size, otherwise a RasterFormatException may be thrown during the iteration. Parameters:   src - The source iterator. Parameters:   dst - The destination iterator. An iterator that read sample from src and write sampleto dst . If src == dst , then the destinationiterator itself is returned. finishedBands public boolean finishedBands()(Code) Returns true if the max band in the image has been exceeded. finishedLines public boolean finishedLines()(Code) Returns true if the bottom row of the bounding rectangle has been passed. finishedPixels public boolean finishedPixels()(Code) Returns true if the right edge of the bounding rectangle has been passed. getPixel public int[] getPixel(int[] array)(Code) Returns the samples of the current pixel from the image in an array of int. getPixel public float[] getPixel(float[] array)(Code) Returns the samples of the current pixel from the image in an array of float. getPixel public double[] getPixel(double[] array)(Code) Returns the samples of the current pixel from the image in an array of double. getSample public int getSample()(Code) Returns the current sample as an integer. getSample public int getSample(int b)(Code) Returns the specified sample of the current pixel as an integer. getSampleDouble public double getSampleDouble()(Code) Returns the current sample as a double. getSampleDouble public double getSampleDouble(int b)(Code) Returns the specified sample of the current pixel as a double. getSampleFloat public float getSampleFloat()(Code) Returns the current sample as a float. getSampleFloat public float getSampleFloat(int b)(Code) Returns the specified sample of the current pixel as a float. jumpLines public void jumpLines(int num)(Code) Jumps downward num lines from the current position. jumpPixels public void jumpPixels(int num)(Code) Jumps rightward num pixels from the current position. nextBand public void nextBand()(Code) Sets the iterator to the next band in the image. nextBandDone public boolean nextBandDone()(Code) Sets the iterator to the next band in the image, and returns true if the max band has been exceeded. nextLine public void nextLine()(Code) Sets the iterator to the next line of the image. nextLineDone public boolean nextLineDone()(Code) Sets the iterator to the next line in the image, and returns true if the bottom row of the bounding rectangle has been passed. nextPixel public void nextPixel()(Code) Sets the iterator to the next pixel in image (that is, move rightward). nextPixelDone public boolean nextPixelDone()(Code) Sets the iterator to the next pixel in the image (that is, move rightward). setPixel public void setPixel(int[] array)(Code) Sets all samples of the current pixel to a set of int values. setPixel public void setPixel(float[] array)(Code) Sets all samples of the current pixel to a set of float values. setPixel public void setPixel(double[] array)(Code) Sets all samples of the current pixel to a set of double values. setSample public void setSample(int s)(Code) Sets the current sample to an integral value. setSample public void setSample(float s)(Code) Sets the current sample to a float value. setSample public void setSample(double s)(Code) Sets the current sample to a double value. setSample public void setSample(int b, int s)(Code) Sets the specified sample of the current pixel to an integral value. setSample public void setSample(int b, float s)(Code) Sets the specified sample of the current pixel to a float value. setSample public void setSample(int b, double s)(Code) Sets the specified sample of the current pixel to a double value. startBands public void startBands()(Code) Sets the iterator to the first band of the image. startLines public void startLines()(Code) Sets the iterator to the first line of its bounding rectangle. startPixels public void startPixels()(Code) Sets the iterator to the leftmost pixel of its bounding rectangle.
