set Tranform Image Pixels 
if (transPixel == null)
    throw new NullPointerException("Transformation Pizel is Null");
int maxCols = origImg.getWidth(), maxRows = origImg.getHeight();
GeneralPath cutoutPath = null;
int startx = 0, starty = 0;
if (cutoutShape != null) {
    cutoutPath = new GeneralPath(cutoutShape);

...
BufferedImagetransparentBG(BufferedImage image, Boolean transparent)
Returns the same image with transparent background instead of white or vice versa. 
BufferedImage tmpImg = new BufferedImage(image.getWidth(), image.getHeight(),
        BufferedImage.TYPE_4BYTE_ABGR);
for (int w = 0; w < image.getWidth(); w++) {
    for (int h = 0; h < image.getHeight(); h++) {
        if (image.getRGB(w, h) == Color.WHITE.getRGB() && transparent) {
            tmpImg.setRGB(w, h, 0);
        } else if (image.getRGB(w, h) == 0 && !transparent) {
            tmpImg.setRGB(w, h, Color.WHITE.getRGB());

BufferedImagetransparentColor(BufferedImage src, Color trColor)
transparent Color 
int w = src.getWidth();
int h = src.getHeight();
BufferedImage dst = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);
if (src.getRaster().getNumBands() < 3) {
