Java图片质量压缩方法

1. 使用ImageIO进行压缩

ImageIO是Java提供的一个用于处理图像的类库，它可以轻松地读取和写入各种图像文件格式。

import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

public class ImageCompression {
    public static void compressImage(String inputImagePath, String outputImagePath, float quality) throws IOException {
        File inputFile = new File(inputImagePath);
        BufferedImage image = ImageIO.read(inputFile);
        File outputFile = new File(outputImagePath);

        ImageIO.write(image, "jpg", outputFile);
    }
}

2. 使用WebP格式

import org.webp.java.WebPImage;

public class WebPCompression {
    public static void compressImage(String inputImagePath, String outputImagePath, float quality) throws IOException {
        WebPImage webPImage = WebPImage.fromFile(new File(inputImagePath));
        webPImage.toFile(outputImagePath, quality);
    }
}

3. 使用第三方库

import net.coobird.thumbnailator.Thumbnailator;
import net.coobird.thumbnailator.geometry.Coordinates;
import net.coobird.thumbnailator.geometry.Positions;

public class ThumbnailatorCompression {
    public static void compressImage(String inputImagePath, String outputImagePath, float quality) throws IOException {
        BufferedImage image = ImageIO.read(new File(inputImagePath));
        BufferedImage compressedImage = Thumbnailator.createThumbnail(image, Coordinates.from(Positions.CENTER), (int) (image.getWidth() * quality));
        ImageIO.write(compressedImage, "jpg", new File(outputImagePath));
    }
}
