Method

voidextractFromPixeldata(short[] pixeldata, int columns, int stride, int mask, byte[] ovlyData, int off, int length)
extract From Pixeldata 
for (int y = 0, i = off, imax = off + length; y < columns && i < imax; y++) {
    for (int j = y * stride; j < imax && i < imax; j++, i++) {
        if ((pixeldata[j] & mask) != 0) {
            ovlyData[i >>> 3] |= 1 << (i & 7);
StringgetRandomPixel(final String fileName)
get Random Pixel 
if (!fileName.equals(file)) {
    img = ImageIO.read(new File(fileName));
    file = fileName;
return String.format("#%06X", (0xFFFFFF
        & img.getRGB((int) (Math.random() * img.getWidth()), (int) (Math.random() * img.getHeight()))));
ImageimageFromIntArray(int[] pixels, int w, int h)
Build an image from a pixel array. 
Image img = Toolkit.getDefaultToolkit().createImage(new MemoryImageSource(w, h, pixels, 0, w));
return img;
int[]pixels(BufferedImage image)
pixels 
return image.getRGB(0, 0, image.getWidth(), image.getHeight(), null, 0, image.getWidth());
byte[]pixelsb(BufferedImage image)
pixelsb 
DataBuffer dataBuffer = image.getRaster().getDataBuffer();
if (dataBuffer instanceof DataBufferByte) {
    return ((DataBufferByte) dataBuffer).getData();
throw new IllegalArgumentException("image is instanceof " + dataBuffer.getClass());
int[][]pixelsFromBufferedImage(final BufferedImage image)
pixels From Buffered Image 
int[][] pixArr = new int[image.getWidth()][image.getHeight()];
for (int x = 0; x < image.getWidth(); x++) {
    for (int y = 0; y < image.getHeight(); y++) {
        pixArr[x][y] = image.getRGB(x, y);

BufferedImagepixelsToImage(int[][] pixels)
pixels To Image 
if (pixels == null) {
    return null;

voidsetRGB(BufferedImage image, int x, int y, int width, int height, int[] pixels)
A convenience method for setting ARGB pixels in an image. 
int type = image.getType();
if (type == BufferedImage.TYPE_INT_ARGB || type == BufferedImage.TYPE_INT_RGB)
    image.getRaster().setDataElements(x, y, width, height, pixels);
else
    image.setRGB(x, y, width, height, pixels, 0, width);
int[]toRgbPixels(BufferedImage image)
to Rgb Pixels 
if (image.getData().getDataBuffer() instanceof DataBufferInt) {
    return ((DataBufferInt) image.getData().getDataBuffer()).getData();
} else {
    return image.getRGB(0, 0, image.getWidth(), image.getHeight(), null, 0, image.getWidth());
