  • Help with displaying images (gif, jpeg...) within a JFrame (or similar)

    Hi all,
    i'm new to the forum and i'll be granted if you kind gentlemen/women could use some advices for my gui home application.
    My purpose is to display a static image in a container (i'd prefer to use javax.swing objects, but if you think that java.awt is more suitable for my app, please feel free to tell me about...). I used a modified code from one of the Java Tutorial's examples, tht actually is an applet and displays images as it is using the paint() method. I just can't realize how to set the GraphicContext in a JFrame or a JPanel to contain the image to display, without using applets. Following part of the code I use (a JButton will fire JApplet start, JApplet is another class file called Apple.java):

    Read the Swing tutorial on "How to Use Labels" or "How to Use Icons" for working examples:
    http://java.sun.com/docs/books/tutorial/uiswing/TOC.html
    By the way you should never override the paint() method. Custom painting (not required in this case) is done by overriding the paintComponent(...) method in Swing. Overriding paint() is an old AWT trick.

    so much wrong with this post...
    a) use the code tags to format the code. Now it is an unreadable mess
    b) scriptlets in your JSP. I don't even want to look at that mess. Learn how to combine servlets and JSPs to create clean, readable and maintainable code in which view logic and business logic are separated. The rule: no java code in your JSP, only tags and EL expressions (learn about JSTL).
    So you get a blank screen. When you do "view source" in your browser, do you see anything there? If nothing, check if you are behind a proxy server. The solution to a post of not too long ago was that the blank screen was being caused by faulty proxy server settings (the user figured it out himself, I don't know what was done to solve it).
    If all this fails you will have to do some debugging magic using your favorite IDE. It will probably be something stupid you are overlooking in the code. It is annoying, but debugging code that does not work is a big part of your job. Better get good at it.

  • Displaying Images in EBS

    Hi,
    Does anybody know if it is possible to use the URL link against an invoice to display an image via UNC path (Oracle 11i)?
    I know it's possible to do this using a URL link through to a browser application but wondering if it's possible to just use the network file path so that the image opens in the native appication on the users machine (windows image viewer, abode etc.)
    Would this be the same method for dispaying images in iExpense too?

    Hi,
    I am having problem displaying images in my Jframe, I want to call a fuction that would connect to a URL web address and would retrieves images using URL web address.
    I would really apperciate it, if somebody can help me out.
    Here is the code:
    import java.awt.*;
    import java.lang.*;
    import java.util.*;
    import javax.swing.*;
    import java.io.*;
    import java.awt.image.*;
    import javax.imageio.*;
    import java.net.*;
    class myPanel extends JPanel
         private Gui myParent;

         public void paintComponent(Graphics g)
                    int x=100, y=40;

                    gigs Tempgigs;
                    for (java.util.Iterator nit=myParent.getgigsListIterator(); nit.hasNext();)
              System.err.print(".");
                    Tempgigs = (gigs) nit.next();
              g.setColor(Color.blue);

  • What is the best way to display image ??

    hi my questions is unusual, there are so many ways to display images.
    I m developing image processing s/w can any one suggest me which would be the best way to display image on which i can perform image operations.
    like in JPanel, icon, trhough paint() or anything else...
    thank you..In advance

    hi man... i think so imaging is better with JAI(Java Advanced Imaging) .... is perfect for display in jcomponent like JPanel or JLabel, you have to replace the paintComponent().
    import java.awt.Graphics;
    import java.awt.Graphics2D;
    import java.awt.Rectangle;
    import java.awt.geom.AffineTransform;
    import javax.media.jai.PlanarImage;
    import javax.swing.JComponent;
    class ImagePanel extends JComponent {
         protected PlanarImage image1;
         protected AffineTransform atx= new AffineTransform();
         protected int width, heigth;
         public ImagePanel() {
         public ImagePanel(PlanarImage i) {
              image1= i;
              width= i.getWidth();
              heigth= i.getHeight();
         public void paintComponent(Graphics gc) {
              Graphics2D g= (Graphics2D)gc;
              Rectangle rect= this.getBounds();
              if ((width != rect.width) || (heigth != rect.height)) {
                   double magx= rect.width / (double)width;
                   double magy= rect.height / (double)heigth;
                   atx.setToScale(magx, magy);
              if (image1 != null)
                   g.drawRenderedImage(image1, atx);
    if you need more info, ask about JAI api and docs

    But in Paper Layout, my report can not display Image field.
    I tried with Web layout and all the other Styles (Except 03 mentioned be Disabled) then all Styles are displayed Imager field OK.

    Here you go..Just follow these steps blindly and you are done.
    1) Create a year prompt with presentation variable as pv_year
    2) Create a report say Mid report with year column selected 3 times
    - Put a filter of pv_year presentation variable on first year column with a default value say @{pv_year}{2008}
    - Rename the second time column say YEAR+1 and change the fx to CAST(TIME_DIM."YEAR" AS INT)+1
    - Rename the second time column say YEAR-1 and change the fx to CAST(TIME_DIM."YEAR" AS INT)-1
    Now when you will run Mid Report, this will give you a records with value as 2008 2009 2007
    3) Create your main report with criteria as Year and Measure col
    - Change the fx for year column as CAST(TIME_DIM."YEAR" AS INT)
    - Now put a filter on year column with Filter based on results of another request and select these:
    Relationship = greater than or equal to any
    Saved Request = Browse Mid Report
    Use values in Column = YEAR-1
    - Again,put a filter on year column with Filter based on results of another request and select these:
    Relationship = less than or equal to any
    Saved Request = Browse Mid Report (incase it doesn't allow you to select then select any other request first and then select Mid Report)
    Use values in Column = YEAR+1
    This will select Year > = 2007 AND Year < = 2009. Hence the results will be for year 2007,2008,2009
    This will 100% work...

  • Problem Displaying Images in a JFrame

    I am writing a program that displays images on a JFrame window. I have been reading the other postings about this topic however I have not been able to make my code work. I am hoping there is some obvious solution that I am not noticing. Please help, I am very confused!
    public class WelcomeWindow {
    private JLabel label;
    private ImageIcon logo;
    public WelcomeWindow() {
    label = new JLabel();
    logo = new ImageIcon("/images/logo.gif");
    label.setIcon(logo);
    this.getContentPane().add(label);

    Instead of a JLabel, have you tried to use a JButton containing the Icon?
    Also (but I think you've done it already), you could do that :
    File iconFile = new File("/images/logo.gif");
    if (!iconFile.isFile()) {
    System.out.println("Not a file");
    That way you'll be certain that the path given is correct.
    Hope this helps.

  • Display image in sub_VI

    I am running a Linux (no NI Vision support) LabVIEW application where I have a “main” DAQ VI collecting raw u8 data. I want to be able to display the data as an image in a sub-VI. The first time I call the sub-VI to display the first image everything works fine, however, on the second and subsequent calls to the sub-VI I get an error saying that the sub-Vi is already open and needs to be closed before being called. I don’t have the screen space to adequately display images in the main VI and still have the DAQ controls visible.
    Is there a way to have one VI continuously collect and format image data and then display the data in a second VI?
    Thanks in advance

    Thank you for the reply
    In the example you provided the sub-VI is called, executes, and terminates. I need to be able to repeatedly call a sub-VI that does not terminate. I need to do this so that I can update an image and allow an operator to view the image (and perform event functions on the image such as mouse click).
    Is there a way for a main VI to call a sub-VI and not have to pend (wait) for the sub-VI to complete execution?
    Is there a way to call (i.e. pass data) to a sub-VI that is already running?
    Thank you again for your help
