Creating a 3x3 matrix of imgs

this is alot easier in objective-c language. but Java class and method throw me off track a bit or it might be the syntax. im not sure.

so i create a array of images like soo

Code:

---

static Image[] imgs;

---

than i init the array by doing soo

Code:

---

imgs = new Image[9];

---

than declare the base URL like soo

Code:

---

URL b_url = null;
try {
b_url = new URL("/home/user/pic/");
}
catch (java.net.MalformedURLException ex){}

---

than use a for loop for assignment if array like so

Code:

---

int part;

for(int i = 0; i<=9; i++){
part = i;
String f_name = "pic_"+part+".jpg";
imgs[i] = getImage(b_url, f_name);
}

---

than i would have to think of a simple algorithm to correctly place the image parts in the "frame".

i do realize that i have to override the paint().
soo like somthing like this

Code:

---

public void paint(Graphics g){
 int x = 0;
 int y = 0;

 for(int i =0; i <=9; i++){
  g.drawImage(imgs[i], x, y, null);
  x = x +100;
  y = y+ 100;
 }
}

---

now i have a theorized concept of how i can make this work but i have a hard time getting out of my mind and transmitting it to the dam keyboard to the computer. may some please fill my blanks.:confused:

(i wish their wasn't so many classes for one objective)
NSImage = every thing about images (obj-c)
Image, BufferedImage, ImageIO, and more (java)

Construct ImageIcons from the images, set them to an array of JLabels and add them to a container that has a GridLayout(3, 3)

i mostly need help with getting the image to show in a frame. but the image is going to be split up more than 9 parts. im just keeping it to small scale so it easier to fix mistake. i want hard-code the coordinates.

this is what my applet is going to do in steps;

#1: Select Image Name;
#2: Initialize Selected Image;
#3: Display Image Parts in respected coordinates;

IF mouse point is on part of (full)image than show popup menu;
each part of the full image will have it own respected popup if assigned one;

so like:
assign popup to image part in (x,y) if no popup assign than proceed else output error || (x+1, y+1);

java is a new langaue for me.. soo the class that java uses is very new to me. im more use to doing C coding and i dont want to rely on java class to do my drawing.

what is the easiest way to display a image with out the need of paint(Graphics g). i would like to override the paint method inside a method of my own is their any way of doing this or will i have to override the pain() in my class as a separate method

basicly how can i init a Graphics var in my own method.

the image will be scalable and will have its own custom bounds. it would trapped in a frame/canvas bound but it should be scrollable by using a drag from mouse. any help with my project?

hidden labels could become of use for logging purposes but i wouldn't want them to be viewable to the public.

maybe im asking to much.:confused:

You have presented a lot of details,
which is ok. This gives the impression
that, at least, this project is not a
homework assignment.

People may have difficulty volunteering
any specific help because you haven't
presented "The problem" you are having.

For example:
The only help I think I can provide is
that you should develope a small
working project without the image
rendering section.

Present this code on the forum to show
the readers where you are having
difficulty coding.

I already told you that.

You don't. And you don't ever need to, as far as painting to a component is concerned.

If you're painting to a BufferedImage, read the API of that class for the correct method to obtain its Graphics reference.

im having a hard time getting a image to load. i look up help and all i get is errors

i tried this code:

Code:

---

import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.IOException;
import java.net.URL;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.imageio.ImageIO;
import javax.swing.JFrame;

/**
 *
 * @author zar
 */
public class loadImage_ {


    private void load(JFrame inFrame) throws IOException{
        URL url = this.getClass().getResource("Image.jpg");
        BufferedImage img = ImageIO.read(url);
        inFrame.setBounds(0,0,img.getWidth(), img.getHeight());
        inFrame.setVisible(true);

        Graphics2D g = (Graphics2D)inFrame.getRootPane().getGraphics();
        g.drawImage(img, null, 0, 0);
    }

    public static void img(){
        loadImage_ li = new loadImage_();
        JFrame frame = new JFrame("Image Display");
        try {
            li.load(frame);
        } catch (IOException ex) {
            Logger.getLogger(loadImage_.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

}

than i get this from the compiler

why am i getting a error from ImageIO.read?

i have the method img() executed from the main() that is in init_()

so like loadImage_.img() in init_.main()

how do i just load a image? just loading it is what im stuck on. and wh is it not finding the image correctly?

There's so much wrong with that code, that I don't think it's worth dissecting. Also, I'm reluctant to give you specific advice when you're ignoring all of Darryl's sound advice without telling us why. I recommend that you dump your current code and do what you should have done all along -- read the graphics tutorials at the Oracle tutorial site. It will show you that Darryl's recommendations are the correct ones.
