Swing/AWT/SWT :: Image Manipulation - Create Application Where Image Is Displayed On One Label
Apr 7, 2014
Sir, I'am new to Swing Programming. I have to create an application where an image is displayed on one Label. The same image has to be split in parts and stored in database pert wise. Later the user has to retrieve the entire image by viewing a small part of the image. I have already displayed the full image on the Label, now i don't know how to split the image and store it part wise in the database.

I need to create an java 2D application for the manipulation of image. I saw the JAI library but it can not install it properly, I also copied the jar but I can not find the solution. How can I do? there is a replacement for JAI? what other libraries can I use?

Trying to get an image to display in a GUI.
try {
ByteArrayInputStream in = new ByteArrayInputStream(
transferWorker.bOutput
.toByteArray());
BufferedImage bufferedImage = ImageIO
.read(in);
[Code] ....
But nothing is happening in the GUI. I have stepped through and bufferedimage contains the data, but its not being displayed. Whats happening is, an image is being transmitted to serial port of laptop, so i'm taking it in and storing it in a BufferOutputStream and then trying to open it in my GUI class.

How can i add a background image for this code without disappearing the button and label? I want a frame that has a background and still shows the buttons and label that I place. and how can I insert Buffered Reader in this code, this is a file organizer, but it only shows first line of a text file.

I've already setted an image retrieving it from an url in this mode
PHP Code: Image img = ImageIO.read(new URL(a.getImmagine()));

imgContainer.setIcon(new ImageIcon(resizedImage)); mh_sh_highlight_all('php');
But i don't know how to do the same thing with a byte format image inteasd of the url...

I successfully added a background image on the Panel but I can't create my JButton image on top of my background image.
ImageIcon piano = new ImageIcon("src/img/piano_backgrd.png");
JLabel backlabel = new JLabel(piano);
panel.add(backlabel, new Integer(Integer.MIN_VALUE));
backlabel.setBounds(0, 0, piano.getIconWidth(), piano.getIconHeight());
JButton volup = new JButton(new ImageIcon("src/img/volup.png"));
volup.setLocation(10, 0);
panel.add(volup);

I'm trying to make a method that takes an image and turns it into a tile image. So if the original image looks like this:
[URL] ....
then the output image should look like this:
[URL] ....
Here's a method that's supposed to do that but for some reason the output image looks the same as the original:
public static int[][] tile(int[][] arr){
int[][] tile = new int[arr.length][arr[0].length];
for (int i = 0; i < arr.length; i++) {
tile[i]=arr[i];
}
return tile;
}
I recently changed the method and the error message I'm getting is "bad operand types for binary operator '+'. Here's the method:
public static int[][] tile(int[][] arr){
int[][] tile = new int[arr.length][arr[0].length];
for (int i = 0; i < arr.length; i++) {
for(int j=0; j<arr[i].length;j++){
tile[j]=(tile[j])+(arr[i]);
}
}
return tile;
}

I have a java swing application.
1. The human user of my application asks it to fire up a scanner which scans a paper document. The document is a filled in form.
2. The application then displays the scanned image to the human user.The image is displayed in a JScrollPane since it may be larger than the scroll pane.
3. The human user needs to locate a certain item in the form, for example a social security number, and enter it into a field in a data entry screen.Note that the image and the field appear on the same screen.
Of-course the social security number always appears in the same location in the image. Also the image needs to be the appropriate magnification and resolution to allow the human user to easily read and understand the item he is searching for in the image.
What is the best way to present the scanned image to the user such that he immediately sees the item he requires and can enter it into the data entry field.

I have added the image in the src and bin directories and cross-checked that the name of the image file is correct..Here is the main class
import javax.swing.*;
public class apples
{
public static void main(String args[])
{
JFrame frame = new JFrame();
MyDrawPanel wid = new MyDrawPanel();
frame.add(wid);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
frame.setSize(300,300);
}
}
and here is the class that does the image adding part
import java.awt.*;
import javax.swing.*;
public class MyDrawPanel extends JPanel
{
public void paintComponent(Graphics g)
{
Image image = new ImageIcon("b.png").getImage();
g.drawImage(image,20, 20, this);

I have a GUI with several buttons and I'm using NetBeans GUI Builder to do. At the click of one of these I would like for it to open another frame containing a picture. So I associate a listener (actionPerformed) the button and when clicked it opens actually post the new frame.
In the new frame I waxed a JLabel and then I associate the image of the label. I saw that to do that NetBeans generates this code:
label.setIcon(new javax.swing.ImageIcon(getClass().getResource("/img/tree.png")));
My problem is that the picture is overwritten several times during the execution of the program is not changed yet in the frame. That is, in the new frame is always displayed an old version of the image.
I have an image that is created every time I click on the button (it always has the same name and same path). Basically I have a generic tree on which I perform the operations (add, remove, etc..). When I click on the button I call a method that generates the image of the tree (using Graphviz). So I have one image that changes over the time...
How can I do so that the image is always up to date?
The Code:
package View;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
public class AlberoIpotesi extends javax.swing.JFrame {
[Code] ....

I can't find any resource on the net about a simple Java code just to move a gif image left or right. I've already accomplished the up, down, and center and they're working fine, thus, I'm still struggling with moving the image left or right. Here's the code.
public class MoveIt extends Applet implements ActionListener
{
private Image cup;
private Panel keypad;
public int top = 10;
public int left = 10;
[Code] ....
I remember in Visual BASIC it's easily achieved by NameOfImage.left = NameOfImage.left - 10 to move left and NameOfImage.left = NameOfImage.left + 10.

I simply want to paint an image on my frame, just once each time the paint() method is called, but how to call the paint method in any good way. This is how it looks:
import java.awt.AWTException;
import java.awt.Dimension;
import java.awt.Graphics2D;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
[Code] ....
I have a frame in another class, and from my assumption I need to somehow tell my paint method to paint on that specific frame right?

I'm currently following this Java tutorial:[URL]
I'm at the Image part of this chapter and I wrote/copied these 2 classes:
[URL]
The error:
Exception in thread "main" java.lang.NullPointerException
at javax.swing.ImageIcon.<init>(Unknown Source)
at image.Board.<init>(Board.java:17)
at image.Image.<init>(Image.java:10)
at image.Image.main(Image.java:20)
I'm fairly certain the problem is the path in this piece of code:
ImageIcon ii = new ImageIcon(this.getClass().getResource("C:GebruikersKristofferworkspaceImagessrcimageNature.jpeg"));
I've done some research and found that I should place the image in the same folder as my .java files, which I did [URL] but the problem still persists.
