 public double[] getPixels(int x, int y, int w, int h, double dArray[], DataBuffer data)
 public float[] getPixels(int x, int y, int w, int h, float fArray[], DataBuffer data)

declare:

  /**
   * @throws ArrayIndexOutOfBoundsException if the coordinates are
   * not in bounds, or if dArray is too small to hold the output.
   */
This statement is not always satisfied. Please see the following code sample that illustrates not throwing ArrayIndexOutOfBoundsException from getPixels() methods.

import java.awt.image.*;

public class Sample {

    public static void main(String[] args) {

        int defaultWidth = 10;
        int defaultHeight = 10;

        DataBuffer data = model.createDataBuffer();

        int numElements = defaultWidth * defaultHeight * model.getNumBands();
        int[] a = new int[numElements];
        for (int j = 0; j < numElements; j++) {
            a[j] = j;
        }
        model.setPixels(0, 0, defaultWidth, defaultHeight, a, data);

        float[] fArray = new float[defaultWidth * defaultHeight * model.getNumBands()];
        /**
