php imagick 文字居中的方法

 public function getwenzinfo($nickName)
 {
 
 $nickNamelen = mb_strlen($nickName, 'utf-8');
 $wzallkd = 0;
 $wzallkdlist = array();
 $wzallkdlist[] = 0;
 $perzifulist = array();
 for ($i = 0; $i < $nickNamelen; $i++) {
 $perzifu = mb_substr($nickName, $i, 1, 'utf-8');
 $perzifulist[] = $perzifu;
 if (preg_match("/^[A-Za-z0-9]+$/", $perzifu) == false) {
 // echo '是中文';
 $wzkd = 26;
 $wzallkd += 26;
 } else {
 // echo '不是中文';
 $wzkd = 17;
 $wzallkd += 15;
 }
 $wzallkdlist[] = $wzkd;
 }
 /*因为字符串宽度是 字符本身宽度+字符之间的间隔-最后的字符串间隔*/
 $wzallkd=$wzallkd-2;
 array_pop($wzallkdlist);
 
 $wenziinfo['wzallkd'] = $wzallkd;
 $wenziinfo['wzallkdlist'] = $wzallkdlist;
 $wenziinfo['perzifulist'] = $perzifulist;
 
 return $wenziinfo;
 }
 
 $text = new /Imagick();
 $text->newImage(750, 1206, 'none');
 
 $text->setImageFormat('png');
 
 $draw1 = new /ImagickDraw();
 $draw1->setFont(__DIR__ . '/../../../Public/tianyangzhongqiu/ziti/fanzhengdahei.ttf'); //设置中文字体 可以解决中文乱码问题
 /*$draw->setTextAlignment(1);*///1 从文字的左下方开始计算的 2 从文字中下来计算 3 从文字右下来计算 默认为1
 $xingzuocolor = $this->getxingzuocolor($xingzuo);
 $draw1->setFillColor(new /ImagickPixel($xingzuocolor));
 $draw1->setFontSize(27);
 $draw1->setTextAlignment(1);
 $nickName = '啦啊';
 $wenziinfo = $this->getwenzinfo($nickName);
 
 $wzallkd = $wenziinfo['wzallkd'];
 $wzallkdlist = $wenziinfo['wzallkdlist'];
 $perzifulist = $wenziinfo['perzifulist'];
 
 $wenzizuobiao = (750 - $wzallkd) / 2;
 
 foreach ($wzallkdlist as $k => $v) {
 $wenzizuobiao += $v;
 
 $draw1->annotation($wenzizuobiao, 240, $perzifulist[$k]);
 }
 
 $draw1->annotation(167, 290, $chengji);
 
 $text->drawImage($draw1);

ps:就是先设置宽度 然后打字 就这样文字宽度我来定 就不会出错了
