Set resolution of a specific JFrame, not the computer's resolution

Question

Is there anyway in Java to set the resolution of a specific JFrame rather than changing the computer's resolution, meaning that if I have JFrame with a size of 100x100 can I make it so the top left point will be (0,0) and the bottom right will be (50,50)? These points being the coordinates inside the JFrame, for example when using Graphics (java.awt.Graphics).

Thank you.

Graphics2D has a scale option, look after it in the Javadoc.

In your case, it's simply this:

public void paintComponent(Graphics g) {
    super.paintComponent(g);

    Graphics2D g2 = (Graphics2D)g;
    g2.scale(0.5, 0.5); // 50% x and 50% y

    // rest of rendering
}

Not until you call `super.paintComponent` ;). Scaling will also NOT effect events (such as mouse events) – MadProgrammer Jun 20 '13 at 00:55
Anyway to do this AND effect events? – user2503315 Jun 20 '13 at 01:03
Look up JXLayer (or JLayer under windows) – MadProgrammer Jun 20 '13 at 01:07
multiply the event's coordinates, the same way as in the scale, `x = evt.getX()*0.5` etc. – Mordechai Jun 20 '13 at 01:09
Take a look at [this](http://stackoverflow.com/questions/16623276/swing-delegate-events-to-child-components-of-transformed-parent/16623435#16623435) and [this](http://stackoverflow.com/questions/14324460/rotating-a-jtextfield-vertically/14328881#14328881) for examples – MadProgrammer Jun 20 '13 at 01:11
