A script for resizing images in Java:

PHP Code:
import java.awt.image.*;
import java.awt.AlphaComposite;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;

public class ImageTest {

    private static final int IMG_WIDTH = 42;
    private static final int IMG_HEIGHT = 42;
    
    public static void main(String [] args){
        
    try{
            File folder = new File("Location of the folder");
            File[] listOfFiles = folder.listFiles();

            for (int i = 0; i < listOfFiles.length; i++) {
                if (listOfFiles[i].isFile()) {
        
                    BufferedImage img = ImageIO.read(listOfFiles[i]);
                    int type = img.getType() == 0? BufferedImage.TYPE_INT_ARGB : img.getType();
                    BufferedImage resizeImagePng = resizeImage(img, type);
                    ImageIO.write(resizeImagePng, "png", new File("c:\\image\\" + listOfFiles[i].getName()));
                    
                }
            }
        }catch(IOException e){
        System.out.println(e.getMessage());
    }
    
        
        
        
    }
    
    private static BufferedImage resizeImage(BufferedImage originalImage, int type){
    BufferedImage resizedImage = new BufferedImage(IMG_WIDTH, IMG_HEIGHT, type);
    Graphics2D g = resizedImage.createGraphics();
    g.drawImage(originalImage, 0, 0, IMG_WIDTH, IMG_HEIGHT, null);
    g.dispose();
        
    return resizedImage;
    }
    
    private static BufferedImage resizeImageWithHint(BufferedImage originalImage, int type){
        
    BufferedImage resizedImage = new BufferedImage(IMG_WIDTH, IMG_HEIGHT, type);
    Graphics2D g = resizedImage.createGraphics();
    g.drawImage(originalImage, 0, 0, IMG_WIDTH, IMG_HEIGHT, null);
    g.dispose();    
    g.setComposite(AlphaComposite.Src);

    g.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
    RenderingHints.VALUE_INTERPOLATION_BILINEAR);
    g.setRenderingHint(RenderingHints.KEY_RENDERING,
    RenderingHints.VALUE_RENDER_QUALITY);
    g.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
    RenderingHints.VALUE_ANTIALIAS_ON);
    
    return resizedImage;
    }    
}

Thank you my friend.
This script was for resizing an image but I edited it to resize multiple images at once.
