Displaying DICOM images in JPanel

Can anyone please tell me how to display DICOM images
using JPanel? I can use JPanel to display ordinary
images but it does not seem to work using DICOM
images. Can anyone please help me out? I've spent
hours and hours trying to solve this problem. Thank
you in advance.The JPanel is only able to display JPEG and GIF images, you will need to decode the DICOM image first and convert to JPEG or GIF format, there are some source codes available on the net. Also check this link out

Displaying an image in JPanel

I have have class called TopPanel which extends a JPanel. The Layout is BorderLayout.
JMenuBar is BorderLayout.NORTH
JToolBar is BorderLayout.SOUTH
I have an image which I want to display on the right hand corner of the panel.
But if do
add(image,BorderLayout.EAST) , it does not display the image .
This is the pseudo code
public class TopPanel extends JPanel{
       public TopPanel() {
            setLayout(new BorderLayout();
            add(menuBar,BorderLayout.NORTH);   //these get added
            add(toolBar,BorderLayout.SOUTH);
            add(image,BorderLayout.EAST);
thank you.

It's just not the image alone, I added a JLabel to test it . Even that doesn't display.

Displaying TIF images from a Servelet?

Hi All,
I have a servlet sitting between database of Images (of type bmp, tif, DICOM) and the HTML query interface.
Baed on the user's input, the servlet queries the database and displays the images. The servelt's code contains
out.println("<a href=\"javascript:NewWindow(1,'" + url + "','" + fname+"')\"><img src = \"" + url + "\" width = \"100\" height = \"100\" alt = \"" + url+"\" /> </a><br>" + fname + "<br><br>");
where url is the path to get the image on the disk.
This works successfully for bmp images but not for tif images. Somebody told me, it does not display tif because IE does not display tif. I would like it to display DICOM images later.
Any suggestions?

1. Convert the image to a format that IE understands.
2. Use a decent browser.

Copying image to jpanel

when i copy an image to jpanel using jlabel i.e
jlabel lab = new jlabel(new Iconimage("xyz.jpg"));
i cannot listen to any keys being pressed on the label when i want to copy the image onto a clip board( cntrl C). Is there any method of listening to keys being pressed on jlabel or a method to display the image on jpanel which listens to keys.

can give code to draw image on Panel.
icon = new ImageIcon("backUp.gif");
JPanel panel = new JPanel()
     protected void paintComponent(Graphics g)
          g.drawImage(icon.getImage(), 0, 0, null);
          super.paintComponent(g);
panel.setOpaque( false );

Problem displaying image in jpanel

Hi,I have posted this on the applet board, but I think its also a general programming problem, so apologies if it isn't relevant to this board, just say so and I'll remove it!
I've got an applet that receives a variable from a PHP page as a parameter. The variable is "map1.png" the map this variable refers to sits in the same folder as the applet.
I want to use this variable along with getDocumentBase() to create a URL which will then be used to display an image within a jPanel called mapPane.
the code I currently have is:
// get image url
String mapURL = getParameter("mapURL");
//set variable for image
Image map_png;
// set media tracker
MediaTracker mt;
//initialise media tracker
mt = new MediaTracker(this);
map_png = getImage(getDocumentBase(),mapURL);
// tell the MediaTracker to kep an eye on this image, and give it ID 1;
mt.addImage(map_png,1);
// now tell the mediaTracker to stop the applet execution
// until the images are fully loaded.
try
mt.waitForAll();
catch (InterruptedException e) {}
// draw image onto mapPane
mapPane.getGraphics().drawImage(map_png, 200, 200, null);
Currently the Parameter is being passed into the applet (i've written it out within the applet) but the image is not being displayed. Does anyone have any suggestions about what I'm doing wrong?
Cheers

hi,
No, don't get any exceptions, the Java Console has a message:

Display a transparent image in JPanel

i just start using Java Graphics Programming fews month ago. there's some problem i facing recently. i doing a simple gif file viewer. first i get the file using the Toolkit and put it in a Image object and use the Gif Decoder to decoded each frame of the Gif File to BufferedImage object and display each of the frame in a JPanel inside a JFrame.My porblem is :-
How to display a transparent image in JPanel? my image source in BufferedImage and how to i know the image is transparent or not?

I simply use ImageIcon object to display the image (*.gif,*.jpg)
JLabel l=new JLabel(new ImageIcon("file path"));
add the label to a panel or frame or dialog
this object no need to use the ImageBuffered Object
It can display any animate gif whether the background is transparent or not.

Display an image on a JPanel

Hi,
I am confused about all the MediaTracker and BufferedImage class used to display an image file (e.g. GIF or JPG) on a JPanel
Can someone provide the steps and also the code snippet of the JPanel's paint() method?
I want to display an image directly on the JPanel.
Thank you.

"the scrollpane doesn't work" is not very descriptive.
So I can't help you with that problem.
The suggested code given to you may not work in all
situations:
1) super.paintComponent(..) tells the panel to paint
all its children (in case you've added any other
components to the panel).
2) drawImage() tells the panel to draw the image over
top of all the children (which defeats the whole
purpose of doing the super.paintComponent())
The safer order should be:
1) drawImage()
2) setOpaque( false )
3) super.paintComponent().
This approach will then work for adding images to the
background of a textArea, textPane etc.Good point that I did not consider since my JPanel is exclusively used for an image with no components added.
If your image is known not to have an alpha channel, you could setOpaque(false) in the extended JPanel's constructor and avoid recalling for every paint (as I am able to do in my situation). You'll probably want to do this in otherwise:
setOpaque(true);
drawImage(image,x,y,observer);
setOpaque(false);
super.paintComponent(g);
since the next call to paintComponent() will already be setOpaque(false) (unless it is automatically reset, which I haven't seen).

Displaying Image on JPanel

Hello, I am having problems trying to display an image on a Panel which is attached to a Frame. I can display an Image on the Frame with no difficulty, however nothing appears when I try to draw on the Panel.
Hope someone can help me with this.
Here is the code
import java.awt.*;
import java.awt.event.*;
class TestFrame extends Frame
     Panel panel;
     public TestFrame()
         setSize(400,400);
         panel = new Panel();
         add(panel);
     public class panel extends Panel
         Image img;
         public panel()
             setSize(400,400);
          setVisible(true);
          img = Toolkit.getDefaultToolkit().getImage("C:\\red.gif");
         public void paint(Graphics g)
          g.drawImage(img,0,0,this);
     public static void main (String[] args)
         TestFrame f = new TestFrame();
         f.setVisible(true);
}

I took a look on your code and I find that 2 things might be wrong with it. See the comments below.
import java.awt.*;
import java.awt.event.*;
class TestFrame extends Frame
     Panel panel;
     public TestFrame()
         setSize(400,400);
     panel = new Panel(); /****You created a Panel object from the the awt package and not an object from the panel class that you defined below. Try using panel= new panel(); or use a anonymous class for this purpose. The picture will never show because it is not using the class that you defined************/
     add(panel);
     public class panel extends Panel /*******Try giving the panel class that you defined another name so as to not confuse you with java.awt.Panel classs. ********/
     Image img;
     public panel()
     setSize(400,400);
          setVisible(true);
img =
=
Toolkit.getDefaultToolkit().getImage("C:\\red.gif");
     public void paint(Graphics g)
          g.drawImage(img,0,0,this);
     public static void main (String[] args)
     TestFrame f = new TestFrame();
     f.setVisible(true);
}Below is a panel class that i think can help. Just pass the appropriate parameters to it.
//container class for the image panel
public class ImagePanel extends Panel {
Image image;
public ImagePanel(Image image) {
this.image = image;
// display the image
public void paint( Graphics g )
// draw the original image
g.drawImage( image, 1, 1, this );

Need help in displaying an Image in a JLabel

Hi everyone,
I am using a JLabel to display images on a particular screen. I am facing some problem while doing so..
On my screen there are images of some garments. When the users select colors from a particular list, i should color this garment images and load it on the screen again with the colors. I have a floodfill class for filling the colors in the images. The problem I am facing is I am able to color the image properly with my floodfill class but when displaying the image on the same jlabel, the image gets distorted somehow.
Everytime I color the image, I create an ImageIcon of the image and use the seticon method from the JLabel class. First I set the icon to null and then set it to the imageicon created. here is the code I use.
If 'image' is the the image i have to load
ImageIcon imgicon = new ImageIcon(image);
jlabel.setIcon(null);
jlabel.setIcon(imgicon);I am setting the icon to null because I have not found any other method to clear the previous image from the jlabel.
Can anyone who has worked on images before and faced a similar situation help me with this?? Is there some other container I can use besides the JLabel to display the images perhaps?
Thanks in advance.....
Bharat

And the thing is when I first go into that screen with the selected colors it is displaying the images perfectly.
It is only giving problems when I pick different colors on the screenit really sounds like the problem is in your floodfill class.
I have no idea what's in floodfill, but if you were e.g. using a JPanel and paintComponent,
you would need to have as the first line in paintComponent()
super.paintComponent(..);
to clear the previous painting.
if not, you would be just drawing over the top of the previous paintComponent(), and if the calculation of the
painting area is not 100% exact, you may get the odd pixel not painted-over, meaning those pixels will display
the old color.

Problem Displaying an Image in a JScrollPane

Hi All,
I've placed a Toolbar at the bottom of a JFrame and above the toolbar I placed a JTabbedPane. In one of the tabs I want to display a full sized image.The size of the image that I want to display using a scroll pane is 595x842 pixels. Now the problem is that when I display the image in the scroll pane the bottom toolbar is overlapped with the scrollpane. I don't want to resize the image as it is spoiling the image quality.I used the below code
JPanel imagepagepanel=new JPanel()
    protected void paintComponent(Graphics g)
          js=new JScrollPane();
          Point p = js.getViewport().getViewPosition();
          g.drawImage(demoicon.getImage(), p.x, p.y, null);
mytabbedpane.addTab("View Image",js); //add the scrollpane to the tabI even tried using a label to display the image in the tabbedpane and I've got the same overlapping problem.
I am able to embed the default browser in my application using JDIC API and the image display is fine in the browser without overlapping the bottom toolbar. But I don't want to use a web browser to display the image.
It would be of great help if anyone could suggest a solution to the overlapping problem. I want the scroll pane to work similar to a web browser while displaying a large sized image.
Thanks in advance.

Override the paintComponent method to just draw the
image at 0, 0, w, h.

        mainPanel.setLayout(new BorderLayout());

        try {
            Image image = ImageIO.read(new File("images/terrain.jpg"));

Don't add() to a JViewport, setView() instead.
