Hi I am new to JAVA programming and I was wondering
how to manipulate an image. I have created a list
screen and I wanted to set a background image in it.
is it possible?Yes, it is. Who exactly it's done depends on what you're actually doing. Read the API docs carefully (I'm thinking about setOpaque methods and overriding the list's paintComponent() method). Also look here,
http://java.sun.com/docs/books/tutorial/uiswing/
- specifically under "custom Painting".

Problem with Image.createImage()

Hi all!
I'm writing a simple midlet just to display an image on the screen and I'm having some problems with Image.createImage()
Here is my code
Image bg_img;
ImageItem imageItem1;
imageItem1 = new ImageItem("", null,ImageItem.LAYOUT_DEFAULT, "");
try{
bg_img = Image.createImage("/image.png");
imageItem1.setImage(bg_img);
catch(java.io.IOException e){
e.printStackTrace();
I'm getting an exception on bg_img = Image.createImage("/image.png");
I can't understand what is it...:(
I know for sure that the problem is not "file not found"
Any one can help me???

If you are catching IOException, then u may have problem with ur image path. "image not found on the specified path." if ur image is not in the current directiry then put it into current directory. otherwise, If u are using resouce folder and it is already included into the resouce path, then put ur image in that folder..try this..
Still not get, then please give some detail about ur development toolkit. and ur apllication packaging scheem. are you using ANT?

Problem with Image file

Hi,
Iam facing with one problem.I have one swing interface through which I can upload files(back end servlet programme).Now I can upload all types of file but problem with image file it uploading perfectly that means size of the uploaded file is ok but its format damaged.It can not be open.My backend servlet programme is ok coz i tested it with html form it is working perfectly.Problem with swing interface.Plz guide me where I done a mistake.Below r my codes:-
ImageIcon Upload=new ImageIcon("images/Upload.gif");
     Button=new JButton(Upload);
     Button.setToolTipText("Upload");
Button.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
          int returnVal = fc.showOpenDialog(ActionDemo4.this);
          if (returnVal == JFileChooser.APPROVE_OPTION) {
          File file = fc.getSelectedFile();
String aa=file.getAbsolutePath();
          textArea3.append(aa);
               textArea2.append("Local URL:");
long l=file.length();
          try

The errors are here:
          byte buff[]=new byte[(int)file.length()];
          InputStream fileIn=new FileInputStream(aa);
          int i=fileIn.read(buff);
          String conffile=new String(buff); (conffile is a String object containing the image)
and here:
String content ="-----------------------------7d11e410e500f2\r\n"+"Con
ent-Disposition: form-data;"+"name=\"upload\";
filename=\""+aa+"\"\r\n"+"Content-Type:
application/octet-strem\r\n\r\n\r\n"+conffile+"--------
--------------------7d11e410e500f2--\r\n";
printout.writeBytes(content);conffie is sent to the server but
it's non possible to treat binary data as String!
Image files must be sent as byte[] NOT as String ......

Problem with images opened in Photoshop CS 5

Hi, I have a problem with images that I open in Photoshop CS 5. F. ex. I opened
the following image:
The image appears with a purple color in Photoshop. If I hover over the image
with a tool like lasso, it temporarily regains it´s original color. The image mode is RGB Color, 8 Bits/Channel.
I resetted the start settings of Photoshop with the CTRL-Shift-Alt-combination, which had no effect.

The confusion arises from the imprecise error message in the Preferences > Performance dialog box, to wit:
OK, that seems to be open to misunderstanding indeed.
The video card: Citrix Systems Inc. Display Driver.
Could not find a list for CS6 specifically, but the card may fall short.
http://helpx.adobe.com/photoshop/kb/tested-video-cards-photoshop-cs5.html
If I invoke View > Proof Colors, the only thing that changes is that the text in the brackets
Also if you set View > Proof Setup to something different?
Boilerplate-text:
Are Photoshop and OS fully updated and have you performed the usual trouble-shooting routines (trashing prefs by keeping command-alt-shift/ctrl-alt-shift pressed while starting Photoshop, 3rd party plug-ins deactivation, system maintenance, cleaning caches, font validation, etc.)?

Problem with image url

Hello,
today I have a problem with image url. I wanted Image to change when mouse dragged over it. But nothing happened. Any ideas?
def maxIco: ImageView = ImageView{
image: Image{

onMouseDragged: function(event: MouseEvent){
maxIco.image = Image{
url: "{__DIR__}ikony/max2.png"
}

This is working for me:
src/main/Main.fx
src/main/icon/image1.bmp
src/main/icon/image2.bmp
//Main.fx
package main;
import javafx.stage.Stage;
import javafx.scene.Scene;

            changed = true;
            println(imgView.image.url);
    onMouseReleased: function (e: MouseEvent): Void {
        imgView.image = Image {

Problems with image scaling

I'm facing a real problem with image scaling
I've used several algorithms but it all has defects but the most common thing is the out of memory error after several enlargments...
does any one know a solution...
note:
I've used several packages to do so,but I'm looking for a solution from the jdk itself
JAlexscorpio

Did you take into account that the getScaledInstance() -method creates a completly new Image?
So if you use it like in
ImageIcon icon1=new ImageIcon("Blah.gif");
ImageIcon icon2=new ImageIcon(icon1.getImage().getScaledInstance(400,400,SCALE_FAST);
you will end up with 2 different Images which have their own data and memory requirements.
even if you use something like
ImageIcon icon1=new ImageIcon("Blah.gif");
Image i=icon1.getImage();
icon1.setImage(i.getScaledInstance(200,200,SCALE_FAST));
You will need enough memory to store the data for the original image, as well as the data for the scaled
version of the image, at least for the time that it take the JRE to create the scaled version. You never know when the garbage collector kicks in to delete you old data so it could be that this takes some time and until
that moment your memory is not available. If your now doing several of the scaling operations, and there is no chance for the garbage collector to do its work, you will run out of memory.
I hope that might help, if not feel free to post again

Copy and Paste Problems with Images

I'm having the strangest problems with images. I copy an image off of the web for one of my art history classes and I go to paste into another program but, whether it's Keynote, Powerpoint, Photoshop, or Graphic Converter, something always goes wrong: the images definitely lose some of their quality, become brighter in appearance, and get jagged on the edges. This is starting to drive me nuts, especially since it never happened in 10.4 on my iBook G4. Any suggestions?

Make it an 8-bit file (Image menu > mode).

Experiencing problem with image display in LR5

I have an intermittent problem with images displaying and exporting in LR. It just began a couple of months ago and is totally random - will do it with RAW (CR2) or JPG. It displays this way in all modules - Library, Develop, Slideshow....The image displays fine in a non-Adobe image viewer (Faststone or Windows Viewer). I've reloaded LR5 and PSCC and is still persists. I know the image file is fine. It also has begun effecting older images that were showing up just fine a while ago. I just loaded about 200 images and maybe 3 or so have this viewing problem in LR & PS. Has anyone else experienced it and have a suggested fix? My graphics card has the latest drivers and shows no problems with other applications. Here is the same image - one a jpg export from Lighroom, the other a save as jpg from Faststone. HELP!

This is almost always a hardware problem, causing corruption of the file. The difference you see between Lightroom and other software is that Lightroom is accessing the full RAW image, while the other software is trying to read the embedded JPG preview.
To figure out exactly what hardware is the problem, you need to try different transmission paths and hardware ... different camera cards, different card readers or USB cables/USB ports, different hard disks, etc. Eventually you should be able to isolate the problem.

My daughter's older Ipod Touch is having a problem with images becoming pixilated when taken from an e-mail and placed into her camera roll. ( She wants to put on Instagram ) Any help?

My daughter's older Ipod Touch is having a problem with images becoming pixilated when taken from an e-mail and placed into her camera roll. ( She wants to put on Instagram ) Any help?

I think that may be a consequence of the email provider she is using. Some services (AOL is one example) inspect and modify email attachments, particularly photos, resulting in reduced resolution compared to the email that was sent.
The iPod does not do this. The resolution of the picture in the email she receives will be identical to what is imported.

Problems with image field and java

Session data will only last as long as the servlet container allows. In most cases (eg Tomcat) this defaults to about 30 minutes, but can be changed. Check that the session timeout configuration in your servlet container hasn't been set to "never timeout".
Even if it had, I would have expected OutOfMemory errors rather than degrading performance. Although if the max heap size of the JVM has been set to a level higher than the RAM on the machine you could be getting excess page file usage.
This probably wouldn't put CPU utilization at 99% though.. I suspect this is a code related problem.
My best guess is one of two reasons:
1. Somewhere in your code, or someone elses, there is a loop that never ends.
2. There is a bug in the servlet container.
I don't know which servlet container you are using, but I have used Tomcat extensively and never seen this behaviour.
In terms of solving this problem, that's a tough one. I would try running the entire application within a profiling tool to see which threads are clogging up the processor. The Eclipse java IDE has a plugin called Eclipse Profiler which will allow you to track the utilization of code right down to the method level.
If it were me, I'd be running the entire web application with a profiler like Eclipse Profiler and waiting for it to start clogging, then see who the guilty code is.

Problem with Image Loading

Hi,
I am using JWS to launch my application. Earlier I was using jdk1.5.0_12 version and everything was working fine. But, one of our machines didnt had jdk1.5.0_12 but had jdk1.5.0_19 version. So, JWS uses "Java Web Start 1.5.0_19" version.
In my code, I am loading images at two different places. At first place I am loading my images using ClassLoader cl = Thread.currentThread().getContextClassLoader();
InputStream baseInputStream = cl.getResourceAsStream(value);
          if(baseInputStream != null){
              ByteArrayOutputStream out = new ByteArrayOutputStream(1024);
              byte[] buffer = new byte[1024];
              int len;
              while((len = baseInputStream.read(buffer)) >= 0)
                  out.write(buffer, 0, len);
              baseInputStream.close();
              out.close();
              imageIcon = new ImageIcon(out.toByteArray());
          }This is working fine. But at the second place, I am setting the look and feel for my application using, SkinLookandFeel.loadDefaultThemePack() method. This method hangs permanently and my application fails to launch. When I debugged this method, I found the following:
1. It goes to loadDefaultThemePack() method of SkinLookAndFeel class. (package: com.l2fprod.gui.plaf.skin)
2. This in turn calls the loadThemePackDefinition((com.l2fprod.gui.plaf.skin.SkinLookAndFeel.class).getResource("/skinlf-themepack.xml")); of SkinLookAndFeel class.
3. The XML file is loaded properly.
4. In method loadThemePackDefinition(), the XML is parsed.
5. This XML has a tag <icon name="InternalFrame.icon" value="icons/Window.gif" />.
6. A URL is formed using URL iconURL = new URL(url, element.getProperty("VALUE"));7. This URL is also formed properly.
8. Next, SkinUtils.loadImage(iconURL) is called.
9. In this method, image is created using method: byte data[] = SkinLookAndFeel.getURLContent(url);
            img = Toolkit.getDefaultToolkit().createImage(data);10. The img variable created here has width and height = -1 with imagerep (consumer) as null, source (producer) as sun.awt.image.ByteAraryImageSource.
11. Then, ImageUtils.transparent(img) method is called.
12. In this method, toBufferedImage(image) method is clalled.
13. in toBufferedImage(image) method, new image is created using image = (new ImageIcon(image)).getImage(); method.
14. This new image created also has width and height = -1 with imagerep (consumer) as sun.awt.image.ImageRepresentation, source (producer) as ByteAraryImageSource.
15. Now, new BufferedImage is created using BufferedImage bufferedImage = new BufferedImage(image.getWidth(null), image.getHeight(null), 2);16. In the constructor of BufferedImage, createCompatibleWritableRaster(width, height) method is called on DirectColorModel. This method throws exception, since width and height are -1.
Points to note are:
1. This is working fine with jdk1.5.0_12 but not with jdk1.5.0_19. I tried this with latest java 1.5 version, jdk1.5.0_21. The problem is still there.
2. When I tried with jdk1.5.0_12, instead of DirectColorModel instance, createCompatibleWritableRaster() method in point 16 above was called on IndexColorModel. I am not creating or initializing any color model, so, I dont know, when does the instance of DirectColorModel or IndexColorModel is used and whether it has any thing to do with my problem.
Can any one provide any pointers, what could be the issue with jdk1.5.0_19.

Have a look throughout the forum (and google), JWS retrieved url syntax changed in 5u16 (or 14 I can never remember).
Otherwise keep waiting for some good samaritan, good luck with it, most people are sick tired of this topic.
Bye.
