import com.google.common.collect.Lists;

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

public class ImageMergedUtil {

    /**
     * 合成图片并添加文字
     *
     * @param outFile 最终合成文件
     */
    public static void merged(File targetImage, List<ImgMergeVO> imgMergeVOList, List<ImgFontVO> imgFontVOList, File outFile) throws IOException {
        // 加载模版图片
        BufferedImage imageLocal = ImageIO.read(targetImage);
        Graphics2D g = null;
        // 加载叠加图片
        if (imgFontVOList != null) {
            for (ImgMergeVO imgMerge : imgMergeVOList) {
                BufferedImage imageCode = ImageIO.read(imgMerge.getMergedImage());
                g = imageLocal.createGraphics();
                // 在模板上添加叠加图片(地址,左边距,上边距,图片宽度,图片高度,未知)
                g.drawImage(imageCode, imgMerge.getLeft(), imgMerge.getTop(), imgMerge.getWidth(), imgMerge.getHeight(), null);
            }
        }

        // 添加文本说明
        if (imgFontVOList != null) {
            for (ImgFontVO imgFont : imgFontVOList) {
                // 设置文本样式
                g.setFont(imgFont.getFont());
                g.setColor(imgFont.getColor());
                g.drawString(imgFont.getText(), imgFont.getLeft(), imgFont.getTop());
            }
        }
        g.dispose();// 完成模板修改
        ImageIO.write(imageLocal, "png", outFile);
    }
}
