Scale multiple images proportionally

The latest function is to scale multiple pictures proportionally to ensure that the width and height of all pictures are equal and not distorted. Now paste the code.

import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class ScaleImage {
    
    
    public static void main(String[] args) throws IOException {
    
    
        // 需要合并的图片文件列表
        List<String> imageFiles = new ArrayList<>();
        File file = new File("E:\\ysj");
        File[] files = file.listFiles();

        for (int i = 0; i < files.length; i++) {
    
    
            imageFiles.add(files[i].getName());
            System.err.println(files[i].getName());
        }
        for (String imageFile : imageFiles) {
    
    
            //加载图片
            File f = new File("E:\\ysj\\" + imageFile);
            BufferedImage image = ImageIO.read(f);
            BufferedImage imag = scaleImage(image, 2400, 4600);
            String[] split = imageFile.split("\\.");
            //保存图片
            File targetFile = new File("E:\\newYsj\\"+ split[0] + ".jpg");
            ImageIO.write(imag, "jpg", targetFile);
        }
    }

    // 等比例缩放图片
    private static BufferedImage scaleImage(BufferedImage img, int maxWidth, int maxHeight) {
    
    
        int width = img.getWidth();
        int height = img.getHeight();

        // 计算缩放比例
        double scale = Math.min((double)maxWidth/width, (double)maxHeight/height);

        // 缩放后的图片宽度和高度
        int newWidth = (int)(width * scale);
        int newHeight = (int)(height * scale);

        // 创建缩放后的图片
        BufferedImage scaledImage = new BufferedImage(newWidth, newHeight, BufferedImage.TYPE_INT_RGB);
        Graphics2D g2d = scaledImage.createGraphics();
        g2d.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
        g2d.drawImage(img, 0, 0, newWidth, newHeight, null);
        g2d.dispose();

        return scaledImage;
    }
}
