How to draw a point without double buffering?

Hello all,
I am drawing points as small red circles, but they are a bit ugly without double buffering. Am I able to draw the points to be nice? I mean not to draw them as just circles, but some special circle with light border that will looks much more nicer?
Or what radius and position of the circle must be to be a nice small circle containing only 5 pixels? (upper, lower, right, left, middle)
ps - they are ugly in the way of having a strange dot on the left side

I use this method:
    private static final float POINT_RADIUS = 2f;
    private static final float POINT_DIAMETER = POINT_RADIUS * 2;
private void drawPoint(float x, float y, Color c) {
        Ellipse2D point = new Ellipse2D.Float(x - POINT_RADIUS, -y
                - POINT_RADIUS, POINT_DIAMETER, POINT_DIAMETER);
        graphics.setStroke(new BasicStroke(0.2f));
        graphics.fill(point);
// and points looks like this:

  • Control mouse pointer without the mouse

    Hello,
    My Mac Mini seems to no longer recognize my mouse. It has been fine for nearly a year though. Both the mouse and keyboard are wireless. The pointer does not move when I move the mouse, but when I press the return button on the keyboard the computer does wake from sleep mode. I don't know how to control the pointer without the mouse though.
    The issues seem to have started when my new version of iTunes seemed to start acting up. The bar at the top of the screen shows that it thinks it is still in iTunes. The computer has been manually turned off and restarted and still comes up the same way, with the mouse pointer in the same spot.
    Does anybody know what the issue may be and also how I can control the pointer without the mouse? I apologize for the lack of knowledge as I'm used to a pc and do not know the keyboard controls on a Mac. Thank you.

    Welcome to the Apple Discussions!
    You should always have an inexpensive USB mouse and keyboard for times such as this. After you have gotten a USB mouse, you can get one at Target for US$10, drag & drop the iTunes app into the Trash. Restart your Mac and while you are at it do a PRAM reset. Then download iTunes from this link and reinstall. Hopefully this will resolve your issues.
    http://www.apple.com/itunes/download/
    Reset the PRAM
    • (Re)start the computer
    • Immediately press & hold the CommandOption+PR keys
    • Wait for two startup chimes
    • Release the keys and allow the computer to boot.
    Also, do you ever repair the disk permissions on your Mac? To repair the disk permissions open Disk Utility in the Apps/Utilities folder. Highlight your startup drive in the list on the left with one mouse click. In the right pane press Repair Permissions. Wait for it to finish.

  • How does buffer size affect double buffered waveform generation?

    I had originally posted the following question:
    "Why does the double buffered waveform generation pause after the first buffer before continuing?"
    "I am using an AT-AO-10 board to generate a multiple channel waveform in double buffered mode. The board's DAC's are updated by an external clock signal. While the waveform generation performs well, I notice that after the first buffer has been generated there is a time delay before the next buffer is output. However the second buffer and thereafter perform well without any time delays. If anyone can provide me an explanation on why this happens I would appreciate it. I am using NI-DAQ API functions to generate the waveforms and my settings for the WFM_DB_Config function are 1 for oldDataStop to disallow regeneration of data and 0 for partialTransferStop to not stop when a half buffer is partially transferred."
    -posted by Vadi on 6/7/2001
    I received a response from Geneva as follows:
    Geneva L. on 6/11/2001 says:
    "Vadi,
    The first thing is to make sure that you have the latest version of NI-DAQ installed, NI-DAQ 6.9.1. If you need to install it, make sure you completely uninstall any prior versions. Then, you will have examples installed in either the NI-DAQ or the CVI directory. In the AO directory, you should find the WFMdoubleBuf example.
    Start with that to make sure the output appears as you expect. Then, you can modify it to apply your external update clock, following the idea presented in the WFMsingleBufExtUpdate example. You might even want to double-check that your external clock acts as you expect using an oscilloscope.
    Finally, modify the example such that you can update on multiple channels, remembering that you interleave each channels buffer into one buffer for WFM_DB_Transfer. Whatever data is in the buffer will be updated on the output channels.

    I have checked my version of NI-DAQ and it is 6.9.1. I am generating the double buffered waveform according to the format shown in WFMdoubleBuf and with some modifications from WFMsingleBufExtUpdate to allow me to use my external update clock. However I continue to notice the same phenomena again and again. For a buffer size of 7500 or 10000 points there is a time lag meaning after the first buffer has been output there is a noticeable time delay before the second buffer and buffers there after is output. This time lag doesn't exist for the buffers that are output after the first buffer but it does exist for the first buffer. When I decrease the buffer size down to 5000 points the time lag disappears (Note: this phenomena also occurs when I use an internal time base as opposed to my external clock). Is there a reason for this? I am using a AT-AO-10 board and I know the on board FIFO is 1024 points deep. However from the documentation provided it doesn't indicate that double buffered mode uses the on board FIFO at all. In fact, the functions require that the FIFO mode be turned off (in WFM_Load) for double buffered waveform generation. Is there a reason why when the buffer size is increased that there is a time lag after the first buffer? Is this because of the functions themselves or is this because of the AT-AO-10 board?

    Vadi,
    Make sure that your buffer size is set to the same number of points that you're actually writing to the buffer initially. For instance, if you run the example as-is, the NIDAQMakeBuffer puts exactly the ulCount amount of data into the buffer. Then, it continuously writes out half buffers. Thus, if you are not writing enough data to fill up the buffer the first time, there will be that lag until the section where half buffers are output.

  • Dragging a drawing when double-buffering

    Hopefully someone out there can help me with this...
    To state the situation simply, I have an applet in which I need to select, drag, and drop in order to move them around. The applet works fine right now, but I can't figure out how to add dragging. The way I have it, you click the object, drag the mouse to where you want to move it, and let go. It then dissapears from where it was, and appears where it was placed. The prolem is that I want to actively see the object being dragged....even an outline would work. As it is, it's difficult to know what you were selecting to move.
    I added a mouseDragged() function to the program, but I see no evidence of it working, which I think has something to do with the double-buffering I used. As far as I can tell, it does draw the object being dragged, it just doesn't ever show up on the screen....
    I would appreciate any input anyone can offer!

  • JNI native drawing - Double Buffering issue

    Hi,
    I use JNI to paint from a C++ DLL onto a canvas, which works fine.
    The problem is that double buffering is not working though.
    In C++ I create an offscreen HDC, draw something on it and finally i bitblit the offscreen HDC to the parent window HDC.
    That is how double buffering is supposed to work. But each time i repaint my Canvas in Java, i see flickering:
    the background color is displayed first, then the C++ paintings are drawn.
    Since i already do double buffering in my C++ drawings, i don't know why there still is flickering.
    Should i do double buffering on my canvas also?
    How would this work, since my paint method looks like;
         private native void drawChart(Graphics g);
         public void paint(Graphics g)
              drawChart(g);
         }

    this is my lucky day :)
    the following thread on http://forum.java.sun.com/thread.jspa?threadID=562392&messageID=2767046 suggested to override the update method on the canvas, which works.
         // overridden to eliminate flicker
        public void update(Graphics g)
            paint(g);
        }

  • Drawing with double buffering to a JFrame

    I want to create a simple JFrame and draw stuff to it via Graphic object using double buffering.
    If I create a loop and draw constantly using JFrame.getGraphic().xxx, am i doing double buffering. ( 'cause i read somewhere that swing components automaticly use double buffering ). And is this the righ approuch ( or whatever it's spelled ) ?

    I want to create a simple JFrame and draw stuff to it
    Don't do that.
    If you want to do custom rendering then use JPanel or JComponent, not JFrame.
    If I create a loop and draw constantly using JFrame.getGraphic().xxx, am i doing double buffering.
    No.
    You're also painting outside the standard paint cycle, which is a Bad Idea.
    So, essentially, everything your suggesting is the wrong way to go about things.
    In its most simple form, double buffering works something like this, though there are a whole load of subtleties to consider (such as component resizing for a start)
    public class Foo extends JComponent
        private BufferedImage image = null;
        protected void paintComponent(Graphics g)
            if (image != null)
                image = createImage(getWidth(), getHeight());
                paintBuffer(ig);
            g.drawImage(image, 0, 0, this);
        private void paintBuffer()
            Graphics ig = image.getGraphics();
            // do the rendering
            ig.dispose();
    }

  • How do you move a track region in Garage Band to a new starting point without altering the existing length of the track?

    How do you move a track region in Garage Band to a new starting point without altering the existing length of the track? Thanks.

    What exactly are you trying to do? You can drag any region by grabbing it in the middle of the upper area with the highlighted name of the region. However, if you move it towards the end of the track, the length of the track will get longer, to accommodate the extra part of the region. DO you want to speed up the region, to shorten it or do you want to trim it? You can simply grab the right margin of the region and drag it, to make the region shorter.

  • How to draw and modify double lines with Adobe Illustrator?

    I need tot draw roadmaps. This should be easy using the pen tool, but my problem is that I cannot find a way to draw double lines with this tool. I have seen many fancy border styles and patterns. Some do have double or even quadruple lines, but the problem is than that they have an offset from the vector line and the space in between the two lines (the edges of the road) cannot be filled. Somewere I also found some pens called 'Double line 1.1' to 'Double line 1.6' but they also had an offset from the vector and I could not chance the size of the lines and the interval in between them independently.
    What I am looking for is a way to draw two lines in parallel and have the option tot fill the space in between with a color or even a pattern.
    The color and size of the lines should be changeable to make a distinction between several types of road.
    Is there an existing set of pencils for this purpose? It would be nice to be able to draw not only roads, but also railways and rivers!
    I am surely not the first person who needs to do this?
    I use AI version 6

    Jacob,
    Thanks for the answer. I have been searching for a solutions for a long
    time, but today I found the solution on a forum (not on this one). That
    solution is exactly as you described below, i.e. using a coloured line and a
    narrower white line on top of the first one. My problem was that I did not
    know how to create a custom brush based on the two lines. Now I know how to
    do that. However, I still have the problem. I can now draw double lines and
    I can change the color of the background line (the coloured one) but I
    cannot change the white colour of the narrower line. I assume that I have to
    completely redefine a new brush when I need to change that colour too.

  • Problem with Double Buffering and Swing

    Hi
    I made a game and basically it works pretty well, my only problem is it flickers really badly right now. I read up on a whole lot of forums about double buffering and none of those methods seemed to work. Then I noticed that Swing has double buffering built in so I tried that but then I get compilation errors and I'm really not sure why. My original code was a console application and worked perfectly, then I ported it into a JApplet and it still works but it flickers and thats what I'm tryign to fix now.
    The code below is in my main class under the constructor.
    Heres the double buffering code I'm trying to use, I'm sure you all seen it before lol
    public void update(Graphics g)
              // initialize buffer
              if (dbImage == null)
                   dbImage = createImage(this.getSize().width, this.getSize().height);
                   dbg = dbImage.getGraphics();
              // clear screen in background
              dbg.setColor(getBackground());
              dbg.fillRect(0, 0, this.getSize().width, this.getSize().height);
              // draw elements in background
              dbg.setColor(getForeground());
              paint(dbg);
              // draw image on the screen
              g.drawImage(dbImage, 0, 0, this);
         }My paint is right under neath and heres how it looks
    This snipet of code works but when I change the method to
    public paintComponent(Graphics g){
    super.paintComponent(g)...
    everythign stops working and get a compilation error and says that it can't find paintComponent in javax.swing.JFrame.
    public void paint(Graphics g)
              super.paint(g);
              //if game starting display menue
              if (show_menue)
                   //to restart lives if player dies
                   lives = 3;
                   menue.draw_menue(g);
                   menue_ufo1.draw_shape(g);
                   menue_ufo2.shape_color = Color.DARK_GRAY;
                   menue_ufo2.draw_shape(g);
                   menue_ufo3.shape_color = Color.BLUE;
                   menue_ufo3.draw_shape(g);
                   menue_ufo4.shape_color = new Color(82, 157, 22);
                   menue_ufo4.draw_shape(g);
                   menue_ufo5.draw_shape(g);
                   menue_ufo6.shape_color = new Color(130, 3, 3); ;

         }I just want to get rid of the flickering for now so any help will be greatly appreciated. Depending which will be simpler I can either try to double buffer this program or port it all to swing but I'm not sure which elements are effected by AWT and which by Swing. Also I read some of the Java documentation but couldn't really understand how to implement it to fix my program.
    Thanks in advance

  • Double buffering

    I was searching through posts to find an answer to my problem of getting double buffering working without flickering when I came across this response:
    Upgrade your SDK, early 1.4 implementations had this problem on Windows2k (It's a bug). Pretty much the second buffer will point to an empty portion of video memory always, the solution to this without updating is to fill the entire backbuffer completely, flip it, fill it again, and then flip it again.

    Since I am on dialup I can't really download the SDK, so could someone give me some code to do what Jason has suggested?

    No I am not recreating the bufferstrategy every frame. Overriding update didn't work either. Here is my code for main:
              GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();
              GraphicsDevice device = env.getDefaultScreenDevice();
              GraphicsConfiguration gc = device.getDefaultConfiguration();
              Frame myFrame = new Frame(gc);
    BufferCapabilities bufferCaps = gc.getBufferCapabilities();
              boolean multiBuffer = bufferCaps.isMultiBufferAvailable();
              boolean fullScreen = device.isFullScreenSupported();
              System.out.println("Full screen supported = " + fullScreen);
              System.out.println("Multi buffer available = " + multiBuffer);
              System.out.println("Page flipping = " + bufferCaps.isPageFlipping());
              myFrame.setUndecorated(true);
              myFrame.setIgnoreRepaint(true);
              if ((fullScreen) && (multiBuffer))
                   device.setFullScreenWindow(myFrame);
                   device.setDisplayMode(new DisplayMode(800, 600, 16, 0));
                   rectBounds = myFrame.getBounds();
                   myFrame.createBufferStrategy(2);
                   bufferStrategy = myFrame.getBufferStrategy();
                   bufferReady = true;
              Game thisGame = new Game(args[0]);
              myFrame.add(thisGame);
    //          myFrame.getContentPane().add(thisGame);
              myFrame.show();
    And here is the relevant code for my run method:
              if (bufferReady)
                   Graphics g = bufferStrategy.getDrawGraphics();
                   if (!bufferStrategy.contentsLost()) {
                        g.fillRect(0,0,getWidth(),getHeight());
                        g.dispose();
                        bufferStrategy.show();

  • Double buffering still gives flickering graphics.

    I copied code from a tutorail which is supposed to illustrate double buffering.
    After I run it, it still flickers though.
    I use applet viewer, which is part of netbeans to run my applet.
    Link to tutorial: http://www.javacooperation.gmxhome.de/TutorialStartEng.html
    My questions are:
    Is the strategy used for double buffering correct?
    Why does it flicker?
    Why does the program change the priority a couple of times?
    Can you make fast games in JApplets or is there a better way to make games? (I think C++ is too hard)

    }Edit 1:
    - For animation code, it would be typical to use a javax.swing.Timer for triggering updates, rather than implementing Runnable (etc.)
    - Attempting to set the thread priority will throw a SecurityException, though oddly it occurs when attempting to set the Thread priority to maximum, whereas the earlier call to set the Thread priority to minimum passed without comment (exception).
    - The paint() method of that applet is not double buffered.
    - It is generally advisable to override paintComponent(Graphics) in a JPanel that is added to the top-level applet (or JFrame, or JWindow, or JDialog..) rather than the paint(Graphics) method of the top-level container itself.

  • Double buffering && repaint

    Hi there,
    I have a frame F that contains two panels P1 and P2.
    P1 uses double buffering for drawing circles and lines.
    P2 has buttons and a JList.
    When i click on a JList to have popup menu
    or when i move the frame F on the screen
    the panel P2 lost some of JList drawing.
    Actually i iconify the frame in order to oblige
    JVM to do repaint.
    How can i resolve this problem please.

    Do not ever mix heavyweight and lightweight, or else
    you won't be able to set up the correct zorder.But when i iconfiy and desiconify my frame Java
    repaint correctly.
    I need a nice tip article of how to simulate
    desiconify repainting process.
    Thabk u

  • Double buffering circle not round

    I am making an applet where some circles are painted to the screen. When not using the double buffering scenario, the shapes appear correctly.
    The problem is when i use the double-buffering technique, the circles are still there, but they look like very ugly. I would call that some "squarcles".
    What is the bug here and how to get some decent double buffering with thoses circles?

    Here is the code so far i have that is used for painting on the screen:
    // Declaration
    private BufferedImage ecran;
    private Graphics2D buffer_ecran;
    // Instantiation
    this.ecran = new BufferedImage(getSize().width, getSize().height, BufferedImage.TYPE_INT_ARGB);
    this.buffer_ecran = ecran.createGraphics();
    // In paint() method
    Graphics be = buffer_ecran;
      // Clean the surface
    be.setColor(Color.WHITE);
    be.fillRect(0, 0, getSize().width, getSize().height);
      // Draw the circles
    be.setColor(Color.RED);
    be.drawOval(x, y, ra, rb);
      // Output the buffer to the screen
    g.drawImage(ecran, 0, 0, this);I was previously using Image and changed to BufferedImage with the hope it would resolve the situation. I can't tell a significant change in image display.

  • Double buffering on large pane

    I have a large JPanel which I'm drawing onto which is about 5000 x 5000. To eliminate screen flicker when dragging objects I'm trying to use double buffering. The problem is the image is too big and I get an out of memory error message.
    I've tried using clipped rectangles to display just the size of image needed but they give erratic results or the scrolling doesn't work. I need it to display the rest of the image when scrolling. Does anyone have any suggestions on how to solve this?
    I've thought about creating the image to be just the size of the screen and to just have the objects that are meant to be at that part but I think this would involve going from device space from user space but I don't know how to do this. Thanks.
    Alan

    ok, if you want it to be interactive with scrolling, then you have to keep the image large, but unless your video card has 71.5MB free space for that image, you're not going to get good results, not to mention CPU will be hurting if you need to do any processing of the image (transforms, loads, saves, etc.)
    options:
    1. forget interaction and just get the viewable image area and paint that portion of the image
    2. Get a graphics supercomputer!
    3. try to fake the interaction somehow
    what else? dunno, did that help
