Fill in a shape

Sun Oct 26, 2008 3:56 am

Hi,

I'm trying to fill in a shape with color made with lines and arcs. The arcs curve inward toward the center of the solid, so fillPolygon and fillArc are not options. Can anyone point me in the right direction?

Thanks,
-Joe

Is this code help you ..

Code:: import java.awt.Container; import java.awt.Graphics; import java.awt.Polygon; import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; import javax.swing.JFrame; import javax.swing.JPanel; public class FillPolyPanel extends JPanel { public void paintComponent(Graphics g) { super.paintComponent(g); int radius = 40; int centerX = 50; int centerY = 100; int angle = 30; int dx = (int) (radius * Math.cos(angle * Math.PI / 180)); int dy = (int) (radius * Math.sin(angle * Math.PI / 180)); g.fillArc(centerX - radius, centerY - radius, 2 * radius, 2 * radius, angle, 360 - 2 * angle); Polygon p = new Polygon(); centerX = 150; for (int i = 0; i < 5; i++) p.addPoint((int) (centerX + radius * Math.cos(i * 2 * Math.PI / 5)), (int) (centerY + radius * Math.sin(i * 2 * Math.PI / 5))); g.fillPolygon(p); p = new Polygon(); centerX = 250; for (int i = 0; i < 360; i++) { double t = i / 360.0; p.addPoint((int) (centerX + radius * t * Math.cos(8 * t * Math.PI)), (int) (centerY + radius * t * Math.sin(8 * t * Math.PI))); } g.fillPolygon(p); } public static void main(String[] args) { JFrame frame = new JFrame(); frame.setTitle("FillPoly"); frame.setSize(300, 200); frame.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent e) { System.exit(0); } }); Container contentPane = frame.getContentPane(); contentPane.add(new FillPolyPanel()); frame.show(); } }

Hi msi_333!

I'm only a novice at Java, but your code shows me the power of the language. Before I saw your post, I wimped out and did it the easy way...

Code:: /**draw truck*/ //draw tires g.fillOval(76,393,48,48); g.fillOval(238,397,44,48); //draw windshield g.drawArc(200,250,75,100,0,90); g.drawLine(275,325,274,300); g.drawLine(200,250,245,251); //draw truck body g.setColor(myGreen); int xs[]={40,40,200,200,225,225,320,325, 285,265,255,240,120,105,95,80}; int ys[]={400,325,325,250,250,325,325, 400,400,390,390,400,400,390,390,400}; int pts=xs.length; g.fillPolygon(xs,ys,pts);

It's just a sort of introductory project for my JAVA 130 class. I just drew little lines instead of an arc.

Now, I just have to figure out how to setBackground() to another color.

Thank you for kind help.
