Concatenates the current Graphics2D Transform with a scaling transformation Subsequent rendering is resized according to the specified scaling factors relative to the previous scaling.

Usage

From source file:Main.java

public static void main(String[] args) throws IOException {

    final int SCALE = 2;

    Image img = new ImageIcon(new URL("http://www.java2s.com/style/download.png")).getImage();

    BufferedImage bi = new BufferedImage(SCALE * img.getWidth(null), SCALE * img.getHeight(null),
            BufferedImage.TYPE_INT_ARGB);

    Graphics2D grph = (Graphics2D) bi.getGraphics();
    grph.scale(SCALE, SCALE);

    grph.drawImage(img, 0, 0, null);//from w w w  . jav a 2 s .co  m
    grph.dispose();

    ImageIO.write(bi, "png", new File("double_size.png"));
}

From source file:ImagePanel.java
