Hello,

I have a downloads page with only pdf files, and the client wants to see thumbnails of the files in addition to download links. I'd like to know if it's possible to extract a thumbnail from the first page of a pdf file. I tried something like this but it returns the pdf icon link:

  class Resource extends DataObject { 
  
  public static $db = array(
    'Title'=>'Varchar(255)'
  );
 
  public static $has_one = array(
    'PDF' => 'File',
    'ResourcesPage' => 'ResourcesPage'
  );

  // Summary fields 
   public static $summary_fields = array( 
      'Thumbnail' => 'Thumbnail',
      'Title' => 'Title'
   );
  
   public function getThumbnail() {
     return $this->PDF()->CMSThumbnail();
  }
 

any idea if I'm missing something here or anyway to accomplish this?

thanks

sajok, I'm running up against the same issue - did you ever figure this out?

I posted about this one a while back. You will have to have ImageMagick installed but it also requires a change to the way the filesystem handles PDFs. I have not managed to kludge it yet.
