How to crop images in Java? I currently have this class for image manipulation.
The main method with the run method:
public static void main(String[] args) {
GameProject gp = new GameProject();
gp.run();
}
public void run(){
s = new Screen();
try {
DisplayMode dm = s.findFirstCompatibleMode(modes);
s.setFullscreen(dm);
Fonts f = new Fonts(); //Checks if certain fonts exsist, if not install them.
Images i = new Images();
try {
i.draw("H:\\Dropbox\\Dropbox\\GameProject\\src\\Resources\\brock.png", 200, 200);
Thread.sleep(50000);
} catch (Exception e) {}
} finally {
s.restoreScreen();
}
}
Images class:
package Handlers;
import javax.swing.ImageIcon;
import java.awt.*;
/**
*
* @author Steven
*/
public class Images {
/**
* @param args the command line arguments
*/
private Screen s;
public void draw(String name, int x, int y) { //Draws the image
s = new Screen();
Graphics2D g = s.getGraphics();
draws(g, name, x, y, getWidth(name), getHeight(name));
}
public void drawA(String name, int x, int y){ //Draws the image, allows for a more advanced image manipulation
s = new Screen();
Graphics2D g = s.getGraphics();
draws(g, name, x, y, getWidth(name), getHeight(name));
}
public void draws(Graphics g, String name, int x, int y, int w, int h) { //Draws and updates the screen
s = new Screen();
g.drawImage(new ImageIcon(name).getImage(), x, y, w, h, null);
s.update();
}
public int getWidth(String name) { //Gets the image width
return new ImageIcon(name).getIconWidth();
}
public int getHeight(String name) { //Gets the images height
return new ImageIcon(name).getIconHeight();
}
}
Any help would be appreciated.

I have used this in my own project :-
public boolean CropImage(int cropHeight,int cropWidth,int windowLeft,int windowTop,File srcFile,String destDirectory,String destFilename,int commonPadding,String fileFormat,HttpServletRequest request)throws IOException{
boolean isOkResolution=false;
try {
String dirPath=request.getRealPath("")+"/"+destDirectory;
File f=new File(dirPath);
if(!f.isDirectory()){
f.mkdir();
}
String destpath=dirPath+"/"+destFilename;
File outputFile=new File(destpath);
FileInputStream fis=new FileInputStream(srcFile);
BufferedImage bimage=ImageIO.read(fis);
System.out.println("Image Origilnal Height=="+bimage.getHeight());
BufferedImage oneimg=new BufferedImage(cropHeight,cropWidth,bimage.getType());
Graphics2D gr2d=oneimg.createGraphics();
isOkResolution=gr2d.drawImage(bimage,0,0,cropWidth,cropHeight,windowLeft-commonPadding,windowTop-commonPadding,(windowLeft+cropWidth)-commonPadding,(windowTop+cropHeight)-commonPadding,null);
gr2d.dispose();
ImageIO.write(oneimg,fileFormat,outputFile);
} catch (FileNotFoundException fe) {
System.out.println("No File Found =="+fe);
} catch(Exception ex){
System.out.println("Error in Croping File="+ex);
ex.printStackTrace();
}
return isOkResolution;
}
This method will help you to crop the image.Its working fine for my project.Hope it will help you out.

You can use CropImageFilter
to crop images. Also, take a look at the java.awt.image package, it does have a lot of image manipulation routines.
