When you use MPDF to convert HTML to PDF, and then convert the PDF to a PNG image, the Chinese error ...

The first step:

Using MPDF (version 6.1) to convert an HTML page to a PDF file, you can go to it successfully. The code is as follows:

$html = "对盲人初学者来说，它无需任何额外的修改。";// $html = "These are the most used acronyms throughout this manual.";include './mpdf/mpdf.php';$mpdf=new mPDF('+aCJK'); $mpdf->autoScriptToLang = true;$mpdf->autoLangToFont = true;$mpdf->WriteHTML($html);$mpdf->Output();

Step Two:

When using Imagick to achieve PDF-to-image,
If there is no Chinese in the PDF file, the conversion succeeds
If the PDF file has Chinese, then direct error:, error code:

Fatal error: Uncaught exception 'ImagickException' with message 'Failed to read the file' in /home/www/test/index-back.php:26 Stack trace: #0 /home/www/test/index-back.php(26): Imagick->readimage('/home/www/test/...') #1 /home/www/test/index-back.php(48): pdf2png('/home/www/test/...', '/home/www/test/...') #2 {main} thrown in /home/www/test/index-back.php on line 26

Note: In addition, I found a public API PDF documentation (basically all in Chinese), using Imagick to convert the PDF to PNG, the success of the conversion ...

PDF to Image code:

function pdf2png($PDF, $Path){   if(!extension_loaded('imagick')){       return false;   }   if(!file_exists($PDF)){       return false;   }   $IM = new imagick();   $IM->setResolution(120, 120);   $IM->setCompressionQuality(100);   $IM->readImage($PDF);   foreach($IM as $Key => $Var){       $Var->setImageFormat('png');       $Filename = $Path.'/'.md5($Key.time()).'.png';       if($Var->writeImage($Filename)==true){           $Return[]= $Filename;       }   }   return $Return;}$pdf = __DIR__.'/1.pdf';$path = __DIR__.'/images';$data = pdf2png($pdf, $path );var_dump($data);

Solution:

使用 MPDF 将HTML转为PDF，然后将该PDF转为PNG图片时有中文怎么才能不报错？？
