二维码生成代码
```
public function make_qrcode($res,$params)
//    public function make_qrcode()
    {
//        $res = Db::name("users_celebrity")->find(72);
//
//        $params = [
//            'name'=>"zhanwan",
//            'cid'=>"70",
//            'uid'=>"75",
//        ];
        $path = "./application/".date("Ymd");
        if(!is_array($params)){
            die('params不是数组形式');
        }
        $url =request()->domain().url('index/detail/index')."?id={$res['u_id']}&";
        foreach ($params as $k => $v){
           $url .= $k.'='.$v."&";
        }
        // Create a basic QR code
        $qrCode = new QrCode($url);
        $qrCode->setSize(120);

// Set advanced options
        $qrCode->setWriterByName('png');
        $qrCode->setMargin(0);
        $qrCode->setEncoding('UTF-8');
        $qrCode->setErrorCorrectionLevel(ErrorCorrectionLevel::HIGH());
        $qrCode->setForegroundColor(['r' => 0, 'g' => 0, 'b' => 0, 'a' => 0]);
        $qrCode->setBackgroundColor(['r' => 255, 'g' => 255, 'b' => 255, 'a' => 0]);
        //$qrCode->setLabel('Scan the code', 16, __DIR__.'/../assets/fonts/noto_sans.otf', LabelAlignment::CENTER());
//        $qrCode->setLogoPath(__DIR__.'/../assets/images/symfony.png');
        //$qrCode->setLogoSize(150, 200);
        $qrCode->setRoundBlockSize(true);
        $qrCode->setValidateResult(false);
        $qrCode->setWriterOptions(['exclude_xml_declaration' => true]);

// Directly output the QR code
        header('Content-Type: '.$qrCode->getContentType());
        $qrCode->writeString();

// Save it to a file
        $qrCode->writeFile("{$path}/ewm_{$res['u_id']}.jpg");

// Create a response object
         $response = new QrCodeResponse($qrCode);
         return $response;
    }
```

图片处理 单人
```
//单人类型 海报生成
    public function type_one($res,$path,$params=[])
    {

// 通过指定 driver 来创建一个 image manager 实例
        $manager = new ImageManager(array('driver' => 'imagick'));

if(!is_file("{$path}/head_{$res['u_id']}.jpg")){
            $head = $res["u_headimgurl"];
            $i = $manager->make($head);
            $i->resize(102,137);
            $i->save("{$path}/head_{$res['u_id']}.jpg");
        }

//二维码生成 参数不一样  二维码每次需要动态生成
        $this->make_qrcode($res,$params);
//        if(!is_file("./application/ewm_{$res['u_id']}.jpg")){
//            $this->make_qrcode($res);
//        }

// 最后创建 image 实例 - 单人堂海报创建
        $image = $manager->make('./jizu/poster/one.jpg');

//头像坐标开始  190   915
        $image->insert("{$path}/head_{$res['u_id']}.jpg", 'top-left', 170, 915);

//二维码坐标  643 922 px
        $image->insert("{$path}/ewm_{$res['u_id']}.jpg", 'top-left', 613, 910);

//姓名文字 开始坐标  308 919
        //$image->insert('./jizu/ewm.jpg');
        //$name = $this->to_unicode($res['u_name']);
        $name = $res['u_name'];
        //p($name);die;

$image->text($name, 288, 919, function($font) {
            $font->file('./jizu/msyh.ttf');
            $font->size(24);
            $font->color('#999999');
            $font->align('left');
            $font->valign('top');
            //$font->angle(45);
        });

//祭奠值 8888 坐标开始位置  377 963
        $image->text($res["u_value"], 377, 963, function($font) {
            $font->file('./jizu/msyh.ttf');
            $font->size(16);

            $font->valign('top');
            //$font->angle(45);
        });

//生辰坐标开始位置362 995
        $image->text($res["u_birthday"], 362, 995, function($font) {
            $font->file('./jizu/msyh.ttf');

            $font->valign('top');
            //$font->angle(45);
        });

//逝世坐标开始位置362 1027
        $image->text($res["u_away_time"], 362, 1027, function($font) {
            $font->file('./jizu/msyh.ttf');

        });
        $image->save("{$path}/poster{$res['u_id']}.jpg");
        $img_url = request()->domain()."/application/".date("Ymd")."/poster{$res['u_id']}.jpg";
        return $img_url;
        
    }
```

图片处理双人
```
//双人类型 海报生成
    public function type_two($res,$path,$params=[])
    {

// 通过指定 driver 来创建一个 image manager 实例
        $manager = new ImageManager(array('driver' => 'imagick'));

以上缺少的包大家请用composer安装之后再测本程序，本程序是基于tp5.1的，有不足之处大家自行优化，字体我是用的微软雅黑，大家复制后替换自己服务器上的字体文件
