Drawing on top of a gif image.
I need to be able to have a JPanel that holds a .gif image, have another JPanel over top of it that can be drawn upon. An example of this is placing a map on a table and laying a piece of clear plastic over top of it, then drawing on the plastic the route you want to take. Just as in this example, I want to be able to erase lines on the top image, but I can probably figure that part out OK, I just need the code to layer the drawing panel on top on the image.
How can this be done?
Thanks.
Exactly what problem are you having with getting a layered pane? The Java Tutorial on this site can give you all the basics regarding setting one up.

To place text or gif image on another gif image
We have requirement to write some content on top of a GIF image. Is it possible to write a text or embed a GIF image on top of a GIF image? We are using jdk1.3.1.
The final image should be a gif or jpeg image.
Using graphics2d drawstring method, we can write a text on a image but graphics2d can be placed on the canvas for displaying purpose but how to convert this graphics2d to bufferedimage so that we can save as gif or jpeg image.Uh oh, another consultancy firm not supplying the correct output to a client. Who woulda thunk?

How can I draw on top of an image?
I'm using a JApplet with three JPanel's inside of it.
Inside one of those JPanel's I would like to place an image and a button. When the button is clicked, I want to draw an oval on top of the image . Each subsequent time the button is clicked, the oval will move to a different location.
So here are my questions:
1) What should I use to draw the image? (a JLabel with an ImageIcon on it?)
2) Could I simply use g.drawOval() in paintComponent() to directly draw on top of the image/JLabel?
Any help will be greatly appriciated.Here's a sample to study;-import java.awt.*;
import java.awt.event.*;
public class DrawOnImage extends java.applet.Applet{
int xPos, yPos;
Image img;
public void init() {
add(new Label("Hello World") );
Button press = new Button("press");
add(press);
press.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
xPos = (int)(Math.random()*270);
yPos = (int)(Math.random()*170)+30;
repaint();
img = getImage(getDocumentBase(), "anImage.JPG");
public void paint(Graphics g){
g.drawImage(img,0,30,this);
if(yPos>=30)g.fillOval(xPos, yPos, 45, 45);

Is it possible to draw moving gif images on a simple Frame applet?
I made an image drawer class for my applet and i can draw simple 2d images.
Here is the basis of my GameSprite class;
public byte[] pixels;
public int width;
public int height;
public GameSprite(String imageName, int requestIndex) {
try {
// Removed code, it's zipInputStream, but it can be used just as ./image.jpg etc
javax.swing.ImageIcon icon = new javax.swing.ImageIcon(fileBytes);
width = icon.getIconWidth();
height = icon.getIconHeight();
pixels = fileBytes;
} catch(Exception e) {
e.printStackTrace();
public void drawSprite(int x, int y) {
try {
Image image = Toolkit.getDefaultToolkit().createImage(pixels);
//Removed code here
graphics.drawImage(image, x, y + 7, width, height, observer);
} catch(Exception e) {
e.printStackTrace();
}If i try to draw an animated gif image it dosn't move.
Thanks for any help.In Java you need to override the paint method in AWT and paintComponenet method in SWING to do graphics/animation. If you go to an offscreen rendering, then you can paint to the graphics context of an image you use for a drawImage in your paint/paintComponent...
If you where overriding a Panel in AWT you would override paint:
public void paint(Graphics g){
g.drawImage(im, 0, 0, this);
}Then where you are maipulating your graphics you would do something like this:
//code snippet
Graphics g = im.getGraphics();
//make what ever changes to im by manipulating the graphics context g
repaint(); -
Hello, I am creating a Card class and a Deck class, and I have .gif images for each card. I am trying to create a CardDisplay class to test my images. The Card/Deck classes work fine, but I am running into problems getting the images to display. What I have is a JFrame and I use a JLabel for each .gif image. When I add the JLabel to the contentPane, it is still only showing a blank window. Can someone give me any guidance as to how to go about this? Also, I am assuming once I get it to display 1 gif, it will display the remaining 51 in the same place. What I am trying to do is to display them all in a row.. well 4 rows of 13 cards that is. Thanks in advance,
dub styleeAlso, just wanted to add that this is not for school. I am doing this for a personal exercise using swing components. I made a card game when I was taking java 1 class, but now I am trying to familiarize myself with the use of graphics. Thanks to anybody who can help.

Problem placing buttons on top of a background image
My knowledge of Java isn't the greatest and I am currently having problems placing buttons on top of a background image within a JApplet (this is also my first encounter with Applets).
I'm using a Card Layout in order to display a series of different screens upon request.
The first card is used as a Splash Screen which is displayed for 5 seconds before changing to the Main Menu card.
When the Main Menu card is called the background image is not shown but the button is.
While the Applet is running no errors are shown in the console.
Full source code can be seen below;

Edited by: bex1984 on May 18, 2008 6:31 AM1) When posting here, please use fewer comments. The comments that you have don't help folks who know Java read and understand your program and in fact hinder this ability, which makes it less likely that someone will in fact read your code and help you -- something you definitely don't want to have happen! Instead, strive to make your variable and method names as logical and self-commenting as possible, and use comments judiciously and a bit more sparingly.
2) Try to use more methods and even classes to "divide and conquer".
3) To create a panel with a background image that can hold buttons and such, you should create an object that overrides JPanel and has a paintComponent override method within it that draws your image using the graphics object's drawImage(...) method
For instance:
an image jpanel:
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.net.URISyntaxException;
import java.net.URL;
import javax.imageio.ImageIO;
import javax.swing.JButton;
import javax.swing.JPanel;
public class BackgroundImage
// **** this will have to be changed for your program:
private static final String IMAGE_PATH = "../../m02/a/images/Forest.jpg";
private BufferedImage myImage = null;
private JPanel imagePanel = new JPanel()
@Override
protected void paintComponent(Graphics g)
{ // *** here is where I draw my image
super.paintComponent(g); // **** don't forget this!
if (myImage != null)
g.drawImage(myImage, 0, 0, this);
public BackgroundImage()
imagePanel.setPreferredSize(new Dimension(600, 450));
imagePanel.add(new JButton("Foobars Rule!"));
try
myImage = createImage(IMAGE_PATH);
catch (IOException e)
e.printStackTrace();
catch (URISyntaxException e)
e.printStackTrace();
private BufferedImage createImage(String path) throws IOException,
URISyntaxException
URL imageURL = getClass().getResource(path);
if (imageURL != null)
return ImageIO.read(new File(imageURL.toURI()));
else
return null;
public JPanel getImagePanel()
return imagePanel;
}and an applet that uses it:
import java.lang.reflect.InvocationTargetException;
import javax.swing.JApplet;
import javax.swing.SwingUtilities;
public class BackgrndImageApplet extends JApplet
@Override
public void init()
try
SwingUtilities.invokeAndWait(new Runnable()
@Override

getContentPane().add(new BackgroundImage().getImagePanel());
catch (InterruptedException e)

Problem at displaying animated gif images !!!!!!!!!!!!
hello everyone......i am trying to display an animated gif image..............so till far i have no issues on this....
but i face problem when :
i have created a class called SimpleGame which extends JPanel....
public class SimpleGame extends JPanel
//code
public void paintComponent(Graphics g)
//code to draw image
}now i have written another class with main method
public class MyGame extends SimpleGame
public MyGame()
JFrame frame=new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(800, 600);
frame.setUndecorated(true);
frame.setLocationRelativeTo(null);
frame.getContentPane().add(this);
frame.setVisible(true);
this.repaint();
}so image gets displayed but only one frame of animated image......image that is displayed is static.....since it is a animated gif,,,,,so some how animation is not rendered......only one frame is displayed......
why is it happening ??
if i try to display animated image from a single class i mean my paintComponent method and main method is at same class then i do not face problem.....
but if my paint method is in another class and i am using that method from another class then animation does not get rendered.........
any help !!!!! please...........class SimpleGame extends JPanel
Image img=new ImageIcon("y.gif");
public void paintComponent(Graphics g)
g.drawImage(img,150,150,this);

Adding GIF images to a stand-alone program
To add a GIF image to an applet one can use the "getImage" function defined in the applet class.
How do i add an image to a stand-alone program in java when one doesn't extend the Applet class ( and so one doesn't have access
to the "getImage" procedure)
I have just begun with Java so please reply in simple english and not in some hard-to-understand "Javian" crap!
Thank uYou mean a JFrame?

Safari downloads gif images for no reason
When I visit this site
www.jsonline.com
some gif images are automatically downloaded (called p-01-OVlaSjnOLG.gif). Every click results in a download. How do I stop this?
Safari version 4.0.4, running on OS X 10.5.8. Lots of space on hard drive.HI and Welcome to Apple Discussions...
If you right or control click an image a pop up menu will appear but just clicking on an image shouldn't result in the file automatically downloading.
Try resetting Safari and emptying the cache.
From the Safari Menu Bar, click Safari / Empty Cache. When you are done with that...
From the Safari Menu Bar, click Safari / Reset Safari. Select the top 5 buttons and click Reset.
Go here for trouble shooting 3rd party plugins or input managers which might be causing the problem.
http://support.apple.com/kb/TS1594
Make sure Safari is not running in Rosetta. Right or control click the Safari icon in your Applications folder then click Get Info. In the Get Info window click the black disclosure triangle so it faces down. Where you see Open using Rosetta... make sure that is NOT selected.
