Usage

From source file:CustomStrokes.java

/** Draw the example */
public void paint(Graphics g1) {
    Graphics2D g = (Graphics2D) g1;
    // Get a shape to work with. Here we'll use the letter B
    Font f = new Font("Serif", Font.BOLD, 200);
    GlyphVector gv = f.createGlyphVector(g.getFontRenderContext(), "B");
    Shape shape = gv.getOutline();

    // Set drawing attributes and starting position
    g.setColor(Color.black);/*from w  ww.  j  av  a  2s .  c o  m*/
    g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
    g.translate(10, 175);

    // Draw the shape once with each stroke
    for (int i = 0; i < strokes.length; i++) {
        g.setStroke(strokes[i]); // set the stroke
        g.draw(shape); // draw the shape
        g.translate(140, 0); // move to the right
