🖼 Rescale Image In Java 🖼

An image can rescaled using AffineTransform. First of all, Image Buffer of input image is created and then scaled image is rendered. ✔️

BufferedImage imgSource = 
   ImageIO.read(new File("myImage.jpg"));

BufferedImage imgDest = 
   new BufferedImage(100, 100,
   BufferedImage.TYPE_INT_RGB);

Graphics2D g2d = imgDest.createGraphics();

AffineTransform affinetransformation =
   AffineTransform.getScaleInstance(2, 2);

g2d.drawRenderedImage(imgSource,
    affinetransformation);

ImageIO.write(imgDest, "JPG", 
   new File("outImage.jpg"));
