我尝试安装magick，并且可以工作，但是当我需要使用PDF文件时，会出错。
我使用xampp
bin / dlls：
我尝试安装ghostpcl-9.27-win32。
版本：
ImageMagick 7.0.8-48 Q16 x86 2019-06-01
$im = new Imagick();
$im->setResolution(300,300);
$im->readimage($pdf->tmp_name);
$im->setImageFormat('jpeg');
$im->cropImage(500, 500, 50, 1420);
$im->writeImage($pdf->tmp_name . '.jpg');
$im->clear();
$im->destroy();
致命错误：带有消息'NoDecodeDelegateForThisImageFormat'TMP'@ error / constitute.c / ReadImage / 501'的C：\ xampp \ htdocs \ adm_engemed_ts5 \ eol \ scr \ savePDF.php：60堆栈跟踪未捕获的异常'ImagickException' ：＃0 C：\ xampp \ htdocs \ adm_engemed_ts5 \ eol \ scr \ savePDF.php（60）：imagick-> readimage（'C：\ xampp \ tmp \ ph ...'）＃1 {main}抛出C ：第60行的\ xampp \ htdocs \ adm_engemed_ts5 \ eol \ scr \ savePDF.php
$im->queryFormats();
