I want to add this image to database how can i do.
View Replies View RelatedI'm relatively new to java and to image processing ... What I've done so far is make a simple application which opens the webcam and can take and save a picture. Ive then loaded the image pixel data into a 2d array. How then do I do what is known as 'fast fourier transform' on it from here?
View Replies View RelatedI have been trying to rotate an image on a certain degree, and still remain on the same position. I have tried g.rotate, but it just rotate around a center, and it does not keep the same position as before.
View Replies View RelatedSir, 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.
View Replies View RelatedI 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 {

I have an applet coded to recieve an image and upon mouse press i wish it to be cropped. For some reason its not implementing, I just think my brain is no longer doing what i think it should be or something, along those lines.

I have been on java applets and it's been fun but I'm stucked with painting a ladybug image on applet using "getImage ( getCodeBase(), "Images/ ladybug.gif") to load the image. It runs but the appletviewer is blank. My applets are not embedded in the web. I just type the codes in eclipse and click the 'run' button.I think the problem is that java is not finding the image in the directory I specified. Please where am I supposed to save the ladybug image so that java can find it on my system whenever I supply the path.

I am trying to create a virus simulation program. The program is supposed to just be a map of the world where the user can click any country in the world to specify where they want their virus to start, specify how transmittable the virus is, and be able to see how the virus spreads through the world by seeing a change in color throughout the world,
I want the world map to initially start out with a very light yellow, and as areas of the world slowly start to get more and more infected by the virus, I want those areas on the map to start changing to a very dark red (going from a light yellow, through shades of orange and red, to dark red).
So, the main idea of this is to have a program that displays an image where certain parts of the image will slowly change color during the runtime of the program. I obviously know how to change colors of certain parts of a window or even an image, but this is very very detailed and advanced but how to even start this.
Okay, gotta be able to move the image when a key is pressed. When I test it, the image moves, but leaves the old image behind.
package Game;
import java.awt.Component;
import javax.swing.JOptionPane;
public class Game
{
private Grid grid; //holds the grid used to store and display images
private int userRow; //keep track of which row the user-controlled image appears in
private int msElapsed; //keep track of the total amount of milliseconds that have elapsed since the start of the game
[Code] ....
Here is what I was given on instructions:
Complete the handleKeyPress method. Write the following line of code in the handleKeyPress method to check for a key press:
int key = grid.checkLastKeyPressed();
If the user pressed the up arrow (key == 38), move the user's image up one row (unless the user is already in the top row). Likewise, if the user pressed the down arrow (key == 40), move the user's image down one row (unless the user is already in the bottom row). Either way, make sure to update userRow.
Movement of the image can be accomplished by changing the value of userRow. Study how the initial image is displayed in the game constructor, then
Set the current image location to null
Update userRow to the new location and,
Set the image in the new value of userRow.
You should be able to move the user image up and down, and you should be prevented from moving the image off the screen.

I have a party registration class in my program. and I have a party registration form in which I want to upload a image(Poll Symbol) for newly register party. but I don't know how to do this.?
I am looking to do it on data carving which is a technique used in digital forensics to extract known file information from unstructered raw data.
So, Lets say I make a bit for bit image of a usb drive that has some deleted images on it, jpeg maybe.
I can still recover this file by locating its header and footer information as its raw data is still on the drive after it has been deleted.
I would like to build a java application to automate this task. My problem is I dont know how to read any of the known digital forensics image (bit for bit copy of the driv) formats such as aff, e01 or raw dd.
Is it possible for me to read bytes from a raw data file in java, maybe search that file for the bytes I need and pull them out of there, perhaps to an array or something ??
I was thinking, if I could get all the raw data into a binary file in java it might be easier to work from there. What I really need is to get access to those bytes. If I could even write them all out to a text file, Id have something to work with.

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;
}
