Usage

From source file:CheckAlignmentOpImage.java

public Raster computeTile(int x, int y) {
    Raster r1 = source1.getTile(x, y);
    Raster r2 = source2.getTile(x, y);

    int xBounds = r1.getWidth();
    if (r2.getWidth() < xBounds)
        xBounds = r2.getWidth();/* ww w .  ja v a2 s  . co  m*/
    int yBounds = r1.getHeight();
    if (r2.getHeight() < yBounds)
        yBounds = r2.getHeight();

    WritableRaster wr;
    wr = r1.createCompatibleWritableRaster(xBounds, yBounds);

    int tmpi;
    int tmpj;
    for (int i = 0; i < wr.getWidth(); i++)
        for (int j = 0; j < wr.getHeight(); j++) {
            tmpi = i / samplingPeriod;
            tmpj = j / samplingPeriod;
            if ((tmpi % 2 == 0) && (tmpj % 2 == 0))
                wr.setDataElements(i, j, r2.getDataElements(i, j, null));
            else if ((tmpi % 2 != 0) && (tmpj % 2 != 0))
                wr.setDataElements(i, j, r2.getDataElements(i, j, null));
            else
                wr.setDataElements(i, j, r1.getDataElements(i, j, null));
        }
