Method

BufferedImageinvert(BufferedImage inImg)
invert 
if (inImg == null) {
    return null;
int width = inImg.getWidth();
int height = inImg.getHeight();
BufferedImage outImg = new BufferedImage(width, height, inImg.getType());
WritableRaster outRaster = outImg.getRaster();
WritableRaster inRaster = inImg.getRaster();
...
voidinvertImage(BufferedImage image)
Perform image invert operation. 
int width = image.getWidth();
int height = image.getHeight();
int new_rgb;
for (int y = 0; y < height; y++) {
    for (int x = 0; x < width; x++) {
        new_rgb = (~(image.getRGB(x, y)));
        image.setRGB(x, y, new_rgb);
voidinvertImage(BufferedImage image)
Inverts a grey scale image. 
WritableRaster inRaster = image.getRaster();
int[] p = new int[3];
float v = 0;
for (int x = 0; x < inRaster.getWidth(); x++) {
    for (int y = 0; y < inRaster.getHeight(); y++) {
        inRaster.getPixel(x, y, p);
        p[0] = 255 - p[0];
        inRaster.setPixel(x, y, p);
...
BufferedImageinvertImage(BufferedImage img, boolean newImage)
Inverts the given image. 
BufferedImage returnImage = img;
if (newImage)
    returnImage = new BufferedImage(img.getWidth(), img.getHeight(), img.getType());
for (int y = 0; y < img.getHeight(); y++) {
    for (int x = 0; x < img.getWidth(); x++) {
        int in = img.getRGB(x, y);
        returnImage.setRGB(x, y, (in & 0xff000000) | ((~in) & 0x00ffffff));
return returnImage;
BufferedImageinvertImage(final BufferedImage savedImage)
invert Image 
final BufferedImage invertedImage;
AffineTransform tx = AffineTransform.getScaleInstance(1, -1);
tx.translate(0, -savedImage.getHeight(null));
AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_NEAREST_NEIGHBOR);
invertedImage = op.filter(savedImage, null);
return invertedImage;
