Displaying overlapping images

Hi,
I have a JWindow to which I have added a JLabel. I have to display images on the JWindow such that when i set a new Icon to the JLabel, it overlaps the previous one.. ie if the new icon is smaller than the previous one then the remaining portion of the previous image should be visible. But this is not occuring. Can anyone help.
Thanks in advance.

The JLabel class's setIcon method revalidates and repaints the label if the previous icon is not the same as the current icon or if the sizes are not the same. To control this behaviour you would need to extend the JLabel class and override its setIcon method to control that behavior. However I'm not sure why you'd want the previous icon showing below the current one. Also be aware that on a repaint request (e.g., minimizing the window and then restoring the window) a window and it's components would be revaildated and repainted if necessary and therefore the previous icon would not show through.

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.

How to draw make the overlapped images on a JToggle Button draggable

Hello all:
I have a JPanel chart set with GridBagLayout. Each cell is a JButton,
I've create several overlaping images (from my existing images) using JLayeredPane
and adding on one particular cell JToggleButton. The images are displayed, but I don't know
how to make it draggable for users to drag to another cell within GridbagLayout.
I have been stuck on this for a long time, I'd appreciate if anyone give me some help
on this.

Hi kglad -
Thanks. That worked perfectly.
Surely you jest with me. Since I couldn't script a play button where in my brain do you think I would I find the cells to "use listeners for the video playing/stopping to control bigPlay_btn's _visible property".
That's okay. I'm sure after answering almost 50,000 questions it's easy to forget who you're talking to.
Thanks again.

Overlapping images in an applet

Hello,
I'm a Java beginner and I would like to write a small applet for a web page. My goal is the following:
The webpage has a background image. So far no problem.The applet should also show a small menu- which is also no greater problem.
Further on, every time the mouse cursor is rolling over a menu image, another image should be displayed overlapping the background image.
This is a problem, because I cannot remove the displayed image without
repainting the entire background image.
I am looking for a method, which can store a well defined image area so I can restore it later.
Thank you for any help !
Stephan

Put your images (rollover or whatever) on a new component - in swing you can use a JLabel - or, I'll assume awt here as its an applet, you can use a Panel. eg
MouseEntered()
inside your area
add(myPanel)
MouseExited()
your area
remove(myPanel)
In the panel you'll need to explicity call on java.awt.Graphics with
Graphics g = myPanel.getGraphics();

Aperture 3 project does not display any images in one Project

This is a strange situation. The bullets below outline the situation:
The project does not display any images
When I place the pointer over the project it shows there are 500+ images
I have located the RAW images stored in my aperture library
I can pull up the images using a smart folder and searching for photos taken on the event day
This is happening only to one of my projects that I know of (weird!!)
I have tried to 're-add' the image by both importing and dragging and dropping into the project, neither works
I tried the following basics:
Fixed permissions
Rebuilt the database
Tried to re-import the data, but when I have the 'don't import duplicates' these are not an option
Found the images in my Aperture library
I created another project and drug all of the images into that project
Any idea how I can fix this?
My fear is that if I delete the original project, the original master images will be deleted.

The most common cause of this is some sort of stuff in the search box at the top of the browser that you don't expect to be there. Just clear it and all your images should show up.
RB
One note - if you drug your images from one project to another it moves them vs copies them unless you hold down the option key.

Problem with displaying BLOB images on JSP page using a servlet

hi. I have a big problem with displaying BLOB images using JSP. I have a servlet that connects to the oracle database, gets a BLOB image , reads it, and then displays it using a BinaryStream. The problem is , this works only when i directly call that servlet, that is http://localhost:8080/ImageServlet. It doesn't work when i try to use that servlet to display my image on my JSP page (my JSP page displays only a broken-image icon ) I tried several coding approaches with my servlet (used both Blob and BLOB objects), and they work just fine as long as i display images explicitly using only the servlet.
Here's what i use : ORACLE 10g XE , Eclipse 3.1.2, Tomcat 5.5.16 , JDK 1.5
here is one of my image servlet's working versions (the essential part of it) :
               BLOB blob=null;
          rset=st.executeQuery("SELECT * FROM IMAGES WHERE ID=1");
          while (rset.next())
               blob=((OracleResultSet)rset).getBLOB(2);
          response.reset();
          response.setContentType("image/jpeg");
          response.addHeader("Content-Disposition","filename=42.jpeg");
                ServletOutputStream ostr=response.getOutputStream();
               InputStream istr=blob.getBinaryStream(1L);
                int size=blob.getBufferSize();
          int len=-1;
                byte[] buff = new byte[size];
                     while ((len=istr.read( buff ))!=-1 ) {
               ostr.write(buff,0,len);
         response.flushBuffer();
         ostr.close(); and my JSP page code :
<img src="/ImageServlet" border="0" > If you could just tell me what i'm doing wrong here , or if you could show me your own solutions to that problem , i would be very greatful ,cos i'm realy stuck here , and i'm rather pressed for time too. Hope someone can help.

I turns out that it wasn't that big of a problem after all. All i had to do was to take the above code and place it into another JSP page instead of into a servlet like i did before. Then i just used that page as a source for my IMG tag in my first JSP. It works perfectly well. Why this doesn't work for servlets i still don't know, but it's not a problem form me anymore . Ofcourse if someone knows the answer , go ahead and write. I would still appriceatte it.
here's the magic tag : <img src="ImageJSP.jsp" border="0" > enjoy : )

Problem with display an image on JFrame in Java 6

I'm trying to display an image on JFrame in this way:
1.) I'm creating a variable in the class:
    private Image imgSpeaker = null;2.) I'm overiting the paint method:
public void paint(Graphics g) {
        super.paint(g);
        g.drawImage(imgSpeaker, 330, 230, null);
    }3.) In the constructor I'm using this code:
   imgSpeaker = Toolkit.getDefaultToolkit().getImage("D:\\speaker.gif");
        MediaTracker trop = new MediaTracker(this);
        trop.addImage(imgSpeaker,0);
        try {
            trop.waitForID(0);    // waiting untill downloading progress will be complite
        } catch (Exception e) {
            System.err.println(e);
        }        The Image will be displayed on form, but if I catch the window and move it (for example: down as possible)
the image is not refreshed (repainted). What I'm doing wrong? I've been used this solution in Java 5 and everything
works perfectly. Any of described methods aren't depricated... Anyone can help me?

Thanks for your code, I've been tryed to apply your solution (with create a Buffered Image), but it still not working correctly. Firstly, the image isn't loading, and secondly the basic problem is not give in. Why have you been using "bg2d.draw(img, x, y, w, h, frame);" not in the paint method?

Display BLOB (image) column in (interactive) report

Hi,
I have a field called "picture" in my table "details" which is of type BLOB. i also have a field for "MIMETYPE" and "filename"
i additionally have a "name" and "description" columns which i need to display along with the picture as columns in a report (preferably interactive).
i have also modified the BLOB display format as per
http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/apex/r31/apex31nf/apex31blob.htm
what i am missing is the correct query. if possible, i would like to control the size of the picture rendered within the report like say 40*50.
I have also referred to the thread
APEX 3.1 Display BLOB Image
But i don't know how to place the
dbms_lob.getlength("BLOB_CONTENT") as "BLOB_CONTENT"
in my query.
The above also makes the report column as of type "number". is this expected?
Any help would be much appreciated.
Regards,
Ramakrishnan

You haven't actually said what the problem is?

Something like:

          name
        , description
        , dbms_lob.getlength(picture) picture
from
          details
if possible, i would like to control the size of the picture rendered within the report like say 40*50.For images close to this size it's easy to do this for declarative BLOB images in interactive reports using CSS. Add a style sheet with:
.apexir_WORKSHEET_DATA td[headers="PICTURE"] img {
display: block;
width: 40px;
border: 1px solid #999;
padding: 4px;
background: #f6f6f6;
}where the <tt>PICTURE</tt> value in the attribute selector is the table header ID of the image column. Setting only one dimension (in this case the width) scales the image with the correct aspect ratio. (The border, padding and background properties are just eye candy...)
However, scaling large images in the browser this way is a huge waste of bandwidth and produces poorer quality images than creating proper scaled down versions using image tools. For improved performance and image quality, and where you require image-specific scaling you can use the database ORDImage object to produce thumbnail and preview versions automatically, as described in this blog post.

How do I display blob (image) in a Portal Report

I am using 9ias 10222 and portal 30983 and I have a table that stores an image as a blob and have a varchar field to store the mime type. I have created a form to upload the image and can then query the form to display the image.
How do I dislay the image in a Portal Report/Dynamic Page Component. I have followed note 68016.1 but the retrieve_img_data procedure does not work it gives a wwv-11230 error.
Any ideas? Any help would be appreciated.
Thanks

Hi,
Can you display what code you used for this? I followed note 172045.1 and everything compiles properly but when I run the report, I just get a box with a red X in it, like it is not finding the picture. I ran the procedure that downloads the image and it works fine from there. Thanks.

How can I display three images in video rate succession (60 Hz)?

For a structured illumination microscope application, I have developed a VI that creates three images and displays them in rapid succession (as fast as the loop will go) on a second monitor.
From the naked eye it's pretty apparent that the loop is not displaying the images at video rate. Is there a way (perhaps with some sort of buffer) to get them to display faster? Is WinShow simply not going to be fast enough, and if not, what's an alternative method of displaying the images? If it helps, the images need only be displayed once each (the loop was just for testing).
Also, what is a way to measure the frame rate output of the images?
(sorry for the sloppy code, new to LabView)
Thanks,
-T

Hello,
Why don't you try drawing one window, call IMAQ WindShow once outside of the loop, then redraw that window each iteration within the loop. Hopefully this stops the flutter of the window. You can build a 3 element array of the 3 IMAQ images then use an index array to alternate through which image you want to be redrawn into the single window. The constant calling of IMAQ WindShow seems messy.

Displaying an image from a URL

I have a program which visits a html page and creates a JComboBox with all the images from that page. When the user selects an image from the combo box it displays that image in a JLabel. This works fine with images that exist, when I try it with an image that doesn't exist I want it to realise that and display a message saying that "the image cannot be found". Heres part of my code that handles the selection:
public void actionPerformed(ActionEvent f) {
                    JComboBox cb = (JComboBox)f.getSource();
                    String imageName = (String)cb.getSelectedItem();
                    try {
                         imageUrl = new URL(imageName);
                    catch (MalformedURLException ex) {
                         System.out.println("Image Collection Error: " + ex);
                    catch (Exception e) {
                         System.out.println("Some sort of exception: " + e);
                    picture.setIcon(new ImageIcon(imageUrl));
          });When I select a bad link image from the list I was hoping the catch blocks would trap it and I could make adjustments accordingly, this does not happen. No exception is thrown at all.
Any ideas of what I can do??
Bow_wow.

Thanks for your help, I have changed it to the following code:
ImageIcon imageToDisplay = new ImageIcon(imageUrl);
                    ImageIcon badImage = new ImageIcon("logo.jpg"); // An image I know exists
                    int status = imageToDisplay.getImageLoadStatus();
                    if (status == MediaTracker.COMPLETE) {
                         picture.setIcon(imageToDisplay);
                    else {
                         picture.setIcon(badImage);
                    }It works now, thanks again for your help!

How do I get a recordset to display three images horizontally?

Hi,
I'm using DWCS3 with MAMP.
I want to display three images horizontally in a recordset. I have downloaded Tom Muck's extension horizontal looper and followed the instructions.
However when I tried to add the recordset navigation bar I ran into some problems.
If I add a repeat region to Tom Muck's extension then the page doesn't load.
If I don't add a repeat region to Tom's extension everything works really well except only one image displays rather than three.

Hi Charles,
Use [Dr%] Variable formula as =if(IsNull([Dr%]);0;[DR%])
Here IsNull returns the Boolean value of variable [Dr%] if its true then inserts 0 else the percentage values of failed tests based on the total number of assembly tests performed.
I Hope this is what you want to achieve....
Thanks....

How to display a image in webdynpro view using a bytearry

Hi Frndz..
How to display an image in a view using webdynpro java ..i have bytearry object in context ..like
*byte[] img = wdContext.nodeYywwwdataImport_Input().nodeOutput().nodeOutMime().currentOutMimeElement().getLine();*_
by using this i need to show image in view..
Kindly help me ....
Thankas in Advance
Regards
Rajesh

Hi,
byte[] img = wdContext.nodeYywwwdata_Import_Input().nodeOutput().nodeOutMime().currentOutMimeElement().getLine();
use this code to create resource and you need to set this value to the context created to display the image suppose in the image UI and set the source property with this attribute:-
IWDResource res=WDResourceFactory.createCachedResource(b,"MyImage",WDWebResourceType.JPG_IMAGE);
IPrivateAppView.IVn_ImageTabElement imageEle=wdContext.createVn_ImageTabElement();
imageEle .setVa_Name(res.toString());
wdContext.nodeVn_ImageTab().addElement(imageEle);
Hope this may help you.

Load and Display Multiple Images in a Web Dynpro Table

I am new to Web Dynpro and I am wondering if anyone can help me with an application that I am currently developing. I have a particular requirement to store images in a database table (not MIME repository) and then display them in a WD table element. An image can be of JPEG, PNG or TIFF format and is associated with an employee record.
I want to create a view in my application that displays multiple images in a table, one image per row. I want to do this using Web Dynpro for ABAP, not Java. I have looked into pretty much all examples available for Web Dynpro and came to the conclusion that Components such as WDR_TEST_EVENTS and WDR_TEST_UI_ELEMENTS do not have any examples of images being stored in a database table and viewed in/from a Web Dynpro table element. Programs such as RSDEMO_PICTURE_CONTROL, DEMO_PICTURE_CONTROL and SAP_PICTURE_DEMO do not show this either.
The images to be displayed in the Dynpro table are to come from a z-type table, stored in a column of data type XSTRING (RAW STRING). So I would also like to know how to upload these images into this z-type table using ABAP code (not Java).
Your help would be greatly appreciated.
