EpsGraphics2D is suitable for creating high quality EPS graphics for use in documents and papers, and can be used just like a standard Graphics2D object.
Many Java programs use Graphics2D to draw stuff on the screen, and while it is easy to save the output as a png or jpeg file, it is a little harder to export it as an EPS for including in a document or paper.
This class makes the whole process extremely easy, because you can use it as if it's a Graphics2D object. The only difference is that all of the implemented methods create EPS output, which means the diagrams you draw can be resized without leading to any of the jagged edges you may see when resizing pixel-based images, such as jpeg and png files.
Example usage:
Graphics2D g = new EpsGraphics2D(); g.setColor(Color.black); // Line thickness 2. g.setStroke(new BasicStroke(2.0f)); // Draw a line. g.drawLine(10, 10, 50, 10); // Fill a rectangle in blue g.setColor(Color.blue); g.fillRect(10, 0, 20, 20); // Get the EPS output. String output = g.toString();
You do not need to worry about the size of the canvas when drawing on a EpsGraphics2D object. The bounding box of the EPS document will automatically resize to accomodate new items that you draw.
Not all methods are implemented yet. Those that are not are clearly labelled.

Method Detail |
public void setAccurateTextMode(boolean b)
Turning off accurate text mode will require the EPS viewer to have the necessary fonts installed. If you are using a lot of text, you will find that this significantly reduces the file size of your EPS documents. AffineTransforms can only affect the starting point of text using this simpler text mode - all text will be horizontal.
