How to crop Images?

[sgthale]

How do you go about cropping images IN AN APPLICATION. I tried using the following code but it only works if placed in an applet. WHICH I DONT WANT.

I have some array of Images.

Image image = images[i];
			Image newImage = createImage(new FilteredImageSource(image.getSource(), new CropImageFilter(1, 1, 21, 20)));

Throws error:

The method createImage(FilteredImageSource) is undefined for the type ImageManager

I imported everything and it just doesnt recognize createImage();

If it is a desktop application, you can use this technique I guess...
byte[] imagedata;
image img;
JFileChooser jFile = new JFileChooser();
try
{
JFileChooser fileChooser = new JFileChooser(".");
FileFilter filter1 = new ExtensionFileFilter("JPG and JPEG", new String[] { "JPG", "JPEG" });
fileChooser.setFileFilter(filter1);
int status = fileChooser.showOpenDialog(null);
if (status == JFileChooser.APPROVE_OPTION) {
file = fileChooser.getSelectedFile();
} else if (status == JFileChooser.CANCEL_OPTION)
{

}

System.out.println(file.getAbsolutePath().toString ());
if(file!=null)
{
String filePath = file.getAbsolutePath();
ImageIcon icon = new ImageIcon(filePath);
Image image = icon.getImage();
image = createImage(new FilteredImageSource(image.getSource(),new CropImageFilter(20, 20, 80, 80)));
lblImage.setIcon(new javax.swing.ImageIcon(image));
}
}

catch(Exception e)
{
e.PrintStackTrace();
}// TODO add your handling code here:

Nope it still doesnt recognize the function

if you are working on desktop application, add this class after the end of your java class it works:

class ExtensionFileFilter extends FileFilter {
String description;

String extensions[];

public ExtensionFileFilter(String description, String extension) {
this(description, new String[] { extension });
}

public ExtensionFileFilter(String description, String extensions[]) {
if (description == null) {
this.description = extensions[0];
} else {
this.description = description;
}
this.extensions = (String[]) extensions.clone();
toLower(this.extensions);
}

private void toLower(String array[]) {
for (int i = 0, n = array.length; i < n; i++) {
array[i] = array[i].toLowerCase();
}
}

public String getDescription() {
return description;
}

public boolean accept(File file) {
if (file.isDirectory()) {
return true;
} else {
String path = file.getAbsolutePath().toLowerCase();
for (int i = 0, n = extensions.length; i < n; i++) {
String extension = extensions[i];
if ((path.endsWith(extension) && (path.charAt(path.length() - extension.length() - 1)) == '.')) {
return true;
}
}
}
return false;
}
}

Doesnt work for me. What you wrote is just the handler for loading images with extensions. ARE YOU SURE YOU ARE NOT RUNNING AN APPLET? I want an application
