Java Applet - Open / Zoom In / Out Of Image
Jul 29, 2014Working on an assignment for a class: Create a DESKTOP application that allows you to open an image file and enables you to zoom in on or out from an image. I believe all I need is too create an open button to open the actual image file, instead of the html link, this code is an example that the teacher provided.My current code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.net.URL;
import java.io.*;
import javax.imageio.*;
[code]....
how to add an open file button so I can search for the file and then open it into my program.
Code For OCR Scanner Not Working As Applet
May 18, 2014I need to make a scanner (that has a built in ocr) output some content to a browser. I haven't gotten to the browser yet, but the code works when I run it as an application. With the scanner, I received Java code that makes the scanner take a picture, then read from it and output it back to the console. I added a few lines to make it an applet:
Java Code:
import gx.*;
import pr.*;
import java.applet.*;
public class DocScan extends Applet {
/**
*
*/
private static final long serialVersionUID = 1L;
[Code] .....
I am using Eclipse as an IDE. Right now my goal is to simply make the scanner "flash". I know that the output is to the console and I will not see anything from it in an applet, but it should still flash.
When I run this code as an application, it works. The scanner takes a picture and then it outputs what it has read to the console.
When I run this code as an Applet, the applet starts and does nothing. It just stays there with no errors of any kind (at least that's what Eclipse is showing me).
I read that I should allow the applet access, so I edited:
Java Code:
c:program filesjavajre8libsecurityjava.policy mh_sh_highlight_all('java');
And added this at the end:
Java Code:
grant {
permission java.security.AllPermission;
}; mh_sh_highlight_all('java');
Which should allow applets full access. However, there is no change - the applet still launches and does nothing. Why is the code not working when I run it as an applet?
Swing/AWT/SWT :: Image Manipulation - Create Application Where Image Is Displayed On One Label
Apr 7, 2014Sir, 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.

Swing/AWT/SWT :: Simple Applet Won't Run
Mar 11, 2002I coded up a simple applet and some html with an applet tag and it tested out OK using the applet viewer. But it doesn't do anything (except draw a grey empty box 100x200) when executed from the application server. For the applicaton server test, I put the applet tag in the HTML Body of the JSP page i.e.
<applet code=CatApplet.class height=100 width=200> </applet>
The applet class file is in the same directory as the JSP page. The source for it is:
import java.awt.*;import java.awt.event.*;import javax.swing.*;import java.io.*;import java.net.*;
import java.util.Date;public class CatApplet extends JApplet{public void init (){setBackground(Color.green);
resize (250,100);}public void paint (Graphics g){g.drawString ("lets get some cat gui going", 35, 15);}}
Why won't my applet run when the applet tags are in the JSP page?

View Replies View RelatedSwing/AWT/SWT :: How To Scroll Image
Sep 30, 2014I 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.
Swing/AWT/SWT :: Why Isn't Image Loading
Jun 20, 2014I 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

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);

View Replies View RelatedSwing/AWT/SWT :: How To Update Image In Java GUI
Jul 10, 2014I 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 {

View Replies View RelatedSwing/AWT/SWT :: Moving Image Left Or Right
Mar 11, 2014I 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.
Swing/AWT/SWT :: How To Paint Image On Frame

import java.awt.Graphics2D;
import java.awt.Rectangle;
import java.awt.Robot;
