The list of methods to do BufferedImage Create are organized into topic(s).

Method

BufferedImageconvertToBufferedImage(BufferedImage image, int imageType)
Converts an image to a buffered image with specified color model/format. 
BufferedImage result = new BufferedImage(image.getWidth(), image.getHeight(), imageType);
Graphics2D g2 = result.createGraphics();
g2.drawImage(image, null, 0, 0);
return result;
BufferedImagegetBufferedImage(byte[] imgStr)
get Buffered Image 
return ImageIO.read(new java.io.ByteArrayInputStream(imgStr));
voidgetBufferedImage(Component comp, BufferedImage image)
Mendapatkan BufferedImage dari sebuah komponen 
Graphics2D g2 = image.createGraphics();
comp.paint(g2);
g2.dispose();
BufferedImagegetBufferedImage(File file)
get Buffered Image 
try {
    return ImageIO.read(file);
} catch (IOException e) {
    e.printStackTrace();
return null;
BufferedImagegetBufferedImage(String imageFile, Component c)
Creates a BufferedImage from the given image file. 
if (imageFile == null || c == null) {
    return null;
BufferedImage bufferedImage = (BufferedImage) imageCache.get(imageFile);
if (bufferedImage != null) {
    return bufferedImage;
Image image = c.getToolkit().getImage(imageFile);
...
BufferedImagegetBufferedImage(String imagePath)
get Buffered Image 
return getBufferedImage(imagePath, false, 0, 1 * 1000);
BufferedImagegetBufferedImageAsType(int type, BufferedImage image, int sizeX, int sizeY)
get Buffered Image As Type 
if (image.getType() == type) {
    return image;
} else {
    BufferedImage result = new BufferedImage(sizeX, sizeY, type);
    Graphics g = result.createGraphics();
    g.drawImage(image, 0, 0, null);
    g.dispose();
    return result;
...
byte[]getBufferedImageBytes(BufferedImage bufferedImage)
get Buffered Image Bytes 
if (bufferedImage == null) {
    throw new IllegalArgumentException("Input the BufferedImage is null.");
ByteArrayOutputStream out = new ByteArrayOutputStream();
byte[] bytes = null;
try {
    ImageIO.write(bufferedImage, "png", out);
    out.flush();
...
BufferedImagegetBufferedImaged(Image img, int width, int height)
This method is used for converting a java.awt.image.Image to scaled BufferedImage of desired width and height. 
Image image = img.getScaledInstance(width, height, Image.SCALE_SMOOTH);
BufferedImage bufferedImg = new BufferedImage(image.getWidth(null), image.getHeight(null),
        BufferedImage.TYPE_INT_RGB);
bufferedImg.getGraphics().drawImage(image, 0, 0, null);
return bufferedImg;
BufferedImagegetBufferedImageFrom3bytePixelArray(int[] rgb, int width, int height)
Converts an integer array with Red, Green and Blue values of each pixel, sequentially, to a BufferedImage 
BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
image.setRGB(0, 0, width, height, rgb, 0, width);
for (int i = 0; i < image.getWidth(); i++) {
    for (int j = 0; j < image.getHeight(); j++) {
        int[] c;
        c = image.getRaster().getPixel(i, j, new int[4]);
        if (c[0] != c[1] || c[0] != c[2] || c[1] != c[2]) {
            System.out.println(c[0] + " " + c[1] + " " + c[2]);
