Shape at "Actual Size"
<p>What's the easy way to render a shape in Java to its "actual size". For example, I have a tube with a diameter of 1" and I want to depict it on screen as the outline of a 1" circle. The Graphics2D method drawOval(int x, int y, int width, int height) takes a height and width  in pixels. What are the steps to translate a pixel size into the size rendered on screen?</p>

<p>Thanks in advance.</p>
