$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);
</pre>

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
