for (int row = 0; row < height / 2; row++) {
    int rowa = row;
    int rowb = height - 1 - rowa;

    System.arraycopy(b, rowb * stride, b, rowa * stride, stride);
    System.arraycopy(tmp, 0, b, rowb * stride, stride);
ObjectflipImage(Object nativeImage, boolean flipHorizontal, boolean flipVertical)
flip Image 
throw new RuntimeException();
ImageflipImageVertically(Image img)
Flips an image vertically. 
int w = img.getWidth(null);
int h = img.getHeight(null);
BufferedImage bimg = toBufferedImage(getEmptyImage(w, h));
Graphics2D g = bimg.createGraphics();
g.drawImage(img, 0, 0, w, h, 0, h, w, 0, null);
g.dispose();
return toImage(bimg);
int[]flipPixels(int[] imgPixels, int imgw, int imgh)
Flip an array of pixels vertically 
int[] flippedPixels = null;
if (imgPixels != null) {
    flippedPixels = new int[imgw * imgh];
    for (int y = 0; y < imgh; y++) {
        for (int x = 0; x < imgw; x++) {
            flippedPixels[((imgh - y - 1) * imgw) + x] = imgPixels[(y * imgw) + x];
return flippedPixels;
