How to resize image to required height and width.
To resize the image firstly need to create a method 'resizeImage()' and pass the required
parameters .
Here the 'resizeImage()' method accept 3 parameters (input Stream,
required Width , required height )
the code is given below.
public static BufferedImage resizeImage(InputStream in, int requiredWidth, int requiredHeight) throws IOException {
BufferedImage bfrImage = ImageIO.read(in);
int imageWidth = bfrImage.getWidth();
int imageheight = bfrImage.getHeight();
double scalex = (double) requiredWidth / imageWidth;
double scaley = (double) requiredHeight / imageheight;
Image scaledImage = null;
scaledImage = bfrImage.getScaledInstance(imageWidth, imageheight, Image.SCALE_SMOOTH);
BufferedImage destination = new BufferedImage(requiredWidth, requiredHeight, BufferedImage.SCALE_SMOOTH);
Graphics2D g2d = destination.createGraphics();
g2d.scale(scalex, scaley);
g2d.drawImage(scaledImage, 0, 0, null);
g2d.dispose();
return destination;
}
