I would like to rotate a rectangle when e.g. y position achieve specified position. I would like to behave a rectangle as a car on a junction - just turn e.g. right. I prefer just rotate and continue. A draft code looks like that: Graphics2D g2d = (Graphics2D) g.create(); g2d.setPaint(new Color(150, 150, 0)); //1. when rectangle achieve 500 on y dimension just rotate left/right if(y==500) { _rotate = true; g2d.rotate(Math.toRadians(90.)); } if(_rotate) { //if rotate, continue way on x dimension ++x ; g2d.fillRect(x, y, 20, 40); } else { //else go to the north --y; g2d.fillRect(x, y, 20, 40); }

I am having problem in creating an transparent rectangle over blurred background. I am trying to do this task on glasspane . Here is my code snippet. void createBlur() { alpha = 1.0f; JRootPane root = SwingUtilities.getRootPane(jf); blurBuffer = GraphicsUtilities.createCompatibleImage(jf.getWidth(), jf.getHeight()); Graphics2D g2d = blurBuffer.createGraphics(); root.paint(g2d); g2d.dispose(); backBuffer = blurBuffer; blurBuffer = GraphicsUtilities.createThumbnailFast(blurBuffer, jf.getWidth() / 2); blurBuffer = new GaussianBlurFilter(5).filter(blurBuffer, null); } where, backBuffer and

Hi i want to convert panel which contains components like label and buttons to image file. I have done the following code. The image was saved. but the content of the panel not visible or saved. Can anyone tell me how to save the panel with its components. Code: package PanelToImage; import java.awt.Color; import java.awt.image.BufferedImage; import java.io.File; import javax.imageio.ImageIO; import javax.swing.*; public class sample extends JPanel { public JPanel firstpanel; public JPanel secondpanel; JLabel label1, label2; JButton button1, button2; public sample() { firstpanel = new JPanel()

I have a JScrollPane and on top of it I have a JPanel named 'panel1'. I want some rectangles to be drawn on this JPanel. I have a class named DrawRectPanel which extends JPanel and does all the drawing stuff. The problem is that, I tried to draw the rectangles on panel1 by writing the following code : panel1.add(new DrawRectPanel()); but nothing appeared on panel1 then I tried, just as a test to the class DrawRectPanel : JFrame frame = new JFrame(); frame.setSize(1000, 500); Container contentPane = frame.getContentPane(); contentPane.add(new DrawRectPanel()); frame.show(); This worked, and

I have Line2D and Arc2D objects laid out on my JPanel by Graphics2D drawing. You can have a look a part of it on this question " How to make pixel perfect Line2D in - Graphics2D ". Now what I want to achieve is, I want to create two parallel lines and arcs for all Line2D and Arc2D objects. Visually, Normal Line2D and Arc2D drawn currently, Want to decorate it like this, My Thoughts so far, I might be able to achieve this by creating two different line and give an offset +gap and -gap from my normal line position. However This will make lots of objects which I don't want to. Now, is it possible
