Open TIFF File With Java

Hey Guys, I'm new to Java and I've got a task in work that I'm not sure how to go about.

Basically, I've got a TIFF file that I need to open in Java, but I haven't got a clue how to do it. I've googled it and I've been taken to Java websites and forums but I'm still really stuck.

I've done some php before but never used java so if someone could help with and guide me through I would really appreciate it :(y):

Thanks,
Ryan

I Guess TIFF images are supported by Java. If it is the Create a Gui using Swing Framework, add a JLabel to it.

Create a ImageIcon as

ImageIcon image = new ImageIcon("location to Image");
label.setIcon(image);


If you don't know Swing or AWT or SWT or Javafx, then Sorry I don't know......

Thanks for the reply, I'm not really sure to be fair :P I've littereally just told to "read a tiff file in Java" I don't know anything about Swing e.t.c

Learning Swing is easy, Look for tutorials and examples on the internet.....

What are you going to do with the data in the file?
That requirement is pretty open.
You could simply open a stream to the file and read the individual bytes in.
So what are you trying to achieve by "read TIFF file"?

Once I'm able to read the tiff file, I would like to be able to read part of the image, like a pacific location to it.

Then read it into a BufferedImage.
You can then read and manipulate the image in Java.

Ok Ill give it a look.

I found this bunch of code here, but I'm confused on what I actually do with it.

Converting Images to BufferedImages [java] [image]

Not sure about that lot
ImageIO is a class that has several read() methods, which return BufferedImages.
That's what you need.

I've seen ImageIO mentioned about. Do I need to download something? If so where do I install the files to?

It's part of the standard Java libraries, so no installation or extra jar files needed.

Ok cool. That's easy enough,

So with this code here for example: A Java program to open, read, and display an image file | devdaily.com, would I just simply copy this, change the file name and save it as a .java file? I'm not too sure what I'm doing here :(-:

Well, first off I'd learn Java.
Mucking about with images and Swing if you don't know the basics (and that really seems to be the case here) is not likely to end happily.
Here's the general tutorials.

I've been though the tutorials.

I'm using this code now:

import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.*;
import javax.imageio.ImageIO;
import javax.swing.*;

public class LoadAndShow extends JPanel {
BufferedImage image;
Dimension size = new Dimension();

public LoadAndShow(BufferedImage image) {
this.image = image;
size.setSize(image.getWidth(), image.getHeight());
}

/**
* Drawing an image can allow for more
* flexibility in processing/editing.
*/
protected void paintComponent(Graphics g) {
// Center image in this component.
int x = (getWidth() - size.width)/2;
int y = (getHeight() - size.height)/2;
g.drawImage(image, x, y, this);
}

public Dimension getPreferredSize() { return size; }

public static void main(String[] args) throws IOException {
String path = "pictures/Snow.jpg";
BufferedImage image = ImageIO.read(new File(path));
LoadAndShow test = new LoadAndShow(image);
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.add(new JScrollPane(test));
f.setSize(400,400);
f.setLocation(200,200);
f.setVisible(true);
//showIcon(image);
}

/**
* Easy way to show an image: load it into a JLabel
* and add the label to a container in your gui.
*/
private static void showIcon(BufferedImage image) {
ImageIcon icon = new ImageIcon(image);
JLabel label = new JLabel(icon, JLabel.CENTER);
JOptionPane.showMessageDialog(null, label, "icon", -1);
}
}

but I keep getting this error back:

Quote:

error: class LoadAndShow is public, should be declared in a file named LoadAndShow.java
public class LoadAndShow extends JPanel {

---

Which is part of the basics.
All public Java class source code should be in a file with the same name as the class name.

One things I might be missing, which I keep hearing about, is JAI. I've found the download, but where do I install it to? Is there a folder in Netbeans I need to put it in?

Why do you think you need that?

I'm not sure, I think cause it supports TIFF files. I want to try and get a .jpg being read first just so I can get something working, all I keep getting is errors

error: class ReadingImage is public

This error comes up all the time

You've been told already, learn the basics first. You have to learn to walk before you try to run.
