I have some pdfs in a folder called downloads and i want to generate thumbnails in jpg format using imagick in php but i am getting error as unable to create temporary file. error i am getting is this:

Fatal error: Uncaught exception 'ImagickException' with message 'unable to create temporary file `/home/vrwebqbj/public_html/virtuereal.com/KyoritsuElectric/admin/images/downloads/demoPDF.pdf': No such file or directory @ error/pdf.c/ReadPDFImage/397' in /home/vrwebqbj/public_html/virtuereal.com/KyoritsuElectric/admin/imagickTest2.php:14 Stack trace: #0 /home/vrwebqbj/public_html/virtuereal.com/KyoritsuElectric/admin/imagickTest2.php(14): Imagick->__construct('/home/vrwebqbj/...') #1 {main} thrown in /home/vrwebqbj/public_html/virtuereal.com/KyoritsuElectric/admin/imagickTest2.php on line 14

This is so far I tried :

<?php
error_reporting(1);
$source       = __DIR__."/images/downloads/demoPDF.pdf"; //Source PDF File
$target     = "myfile.jpg"; // Output File



/*function genPdfThumbnail($source, $target)
    {*/
        //$source = realpath($source);
        $target = dirname($source).DIRECTORY_SEPARATOR.$target;
        //echo $target;
        //echo __DIR__;
        $im     = new Imagick($source."[0]"); // 0-first page, 1-second page
        $im->setImageColorspace(255); // prevent image colors from inverting
        $im->setimageformat("jpeg");
        $im->thumbnailimage(160, 120); // width and height
        $im->writeimage($target);
        $im->clear();
        $im->destroy();
   // }
    //genPdfThumbnail('images/downloads/demoPDF.pdf','myfile.jpg');
?>
<img src="KyoritsuElectric/admin/images/downloads/myfile.jpg" />

Solution 1

You are building the target path using the complete source path appended to your home directory. But imagemagick will not create non-existing directories but expects them to exist already (background: it just tries to create the file using a file open function that fails when the directory does not exist).

So you have two options:

Create the directory dirname($source) below your home directory before executing imagemagick, or
Use another existing directory to store the converted file.

I changed my code as:
$source = "images/downloads/demoPDF.pdf"; //Source PDF File
$target = "images/downloads2/myfile.jpg"; // Output File

both downloads and downloads2 folders exist when seen through filezilla

Where do they exist?
Both are relative pathes to the current working directory. If that is the valid upper path, the conversion should work.

I didn't understand by the line: "Create the directory dirname($source) below your home directory before executing imagemagick"

Jochen Arndt 19-Jan-16 2:51am

For your example, imagemagick fails at creating the file

'/home/vrwebqbj/public_html/virtuereal.com/KyoritsuElectric/admin/images/downloads/demoPDF.pdf'.

So you must create the directory '/public_html/virtuereal.com/KyoritsuElectric/admin/images/downloads' (which is returned by dirname($source)) below your home directory '/home/vrwebqbj'.
