<p>By uploading a PDF attachment, this plugin convert the cover page to jpeg and attach it as a post thumbnail file. It also allows displaying a thumbnail icon and inserting PDF link with a cover image into the editor.</p>
<h4>Available only for WordPress 4.0+, also only on the server which  ImageMagick and GhostScript are installed.</h4>
<p>This plugin hooks to the media editor and generates the first page image of PDF by using ImageMagick with GhostScript. It requires no setup, just activate the plugin via the admin install page. Allow to set a PDF as an image.</p>
<h4>How it works</h4>
<p>This Plugin replaces and extends the following features.</p>
<ul>
<li>Generate cover image of PDF by using ImageMagick. Generated Image has different size variations and is attached to PDF.</li>
<li>Register Generated Image as Featured Image (post-thumbnail) of PDF.</li>
<li>Display Generated Image as icon instead of Mime-type Icon in Admin Page.</li>
<li>Hide Generated Image file itself in Media Library. (v1.2 or later)</li>
<li>Replace link text with JPG when inserting PDF to Text Editor.</li>
<li>Delete Generated Image when deleting PDF from Media Library.</li>
<li>Allow to manage and output Generated Image and PDF on manually in template file. (see Other Notes.)</li>
<li>Allow to set PDF as Featured Image and to use functions in the same way as image file. (v1.2 or later, see Other Notes.)</li>
<li>Allow to control maximum size of Generated Image and other default settings in Plugin Page. (v1.3.4 or later)</li>
</ul>
<h4>Generated Items</h4>
<p>A generated image file is registered as post children of a PDF file and it has different size variations. Files build a tree like below.</p>
<ul>
<li>my-file.pdf (Your PDF)
<ul>
<li>my-file-pdf.jpg (Generated Cover Image of Your PDF)
<ul>
<li>my-file-pdf-1024×768.jpg (Large Size)</li>
<li>my-file-pdf-300×225.jpg (Medium Size)</li>
<li>my-file-pdf-150×150.jpg (Thumbnail size)</li>
<li>…(And Your Custom File Sizes)</li>
</ul>
</li>
</ul>
</li>
</ul>
<h4>Insert HTML into the editor</h4>
<p>Select a PDF file in the Media Uploader and insert it into the the editor. An output HTML is automatically rewritten like below.</p>
<pre><code><a class="link-to-pdf" title="dummy-pdf" href="http://exmaple.com/wp-content/uploads/2015/01/dummy-pdf.pdf" target="_blank"><img width="227" height="320" class="size-medium wp-image-9999 thumb-of-pdf" src="http://exmaple.com/wp-content/uploads/2015/01/dummy-pdf-pdf-227x320.jpg" alt="thumbnail-of-dummy-pdf" /></a>
</code></pre>
<p>*If you are using a document viewer plugin (like GDE) and want insert html which is made by it, select “Default (Title)” of “media” selector.</p>
<h4>Get thumbnail in template file</h4>
<p>A generated image ID is stored in [‘_thumbnail_id’] custom field of a PDF attachment post. An image ID is exportable by using get_post_thumbnail_id($your_pdf_id) or get_post_meta($your_pdf_id, ‘_thumbnail_id’, true) functions in a template file.</p>
<pre><code>$pdf_id = 'your PDF file ID';
if ( $thumbnail_id = get_post_thumbnail_id( $pdf_id ) ) {
echo '<a class="pdf-link image-link" href="'.wp_get_attachment_url( $pdf_id ).'" title="'.esc_attr( get_the_title( $pdf_id ) ).'" target="_blank">'.wp_get_attachment_image ( $thumbnail_id, 'medium' ).'</a>';
}
</code></pre>
<p>Or more simply, you can call images and link to PDF files by wp_get_attachment_image($your_pdf_id, $size) and wp_get_attachment_link($your_pdf_id, $size) functions. (v1.2 or later) *If the plugin is deactivated, this function just will return empty.</p>
<pre><code>$pdf_id = 'your PDF file ID';
echo wp_get_attachment_image ( $pdf_id, 'medium' );
echo wp_get_attachment_link ( $pdf_id, 'medium' );
</code></pre>
<p>If you call all PDFs that are attached to the post. You can get them by get_posts function.</p>
<p>Examples.<br />
Dynamically get PDFs that are attached to the post.</p>
<pre><code><?php
$pdfs = get_posts( 'posts_per_page=-1&post_type=attachment&post_mime_type=application/pdf&post_parent='.$post->ID );
if( $pdfs ): foreach( $pdfs as $pdf ):
  $thumbnail_id = get_post_thumbnail_id( $pdf->ID );
  if( $thumbnail_id ):
    echo '<li>';
    echo '<a href="'wp_get_attachment_url( $pdf->ID )'" class="link-to-pdf">';
    echo wp_get_attachment_image ( $thumbnail_id, 'medium' );
    echo '</a>';
    echo '</li>';
  endif;
endforeach; endif;
?>
</code></pre>
<h4>Set PDF thumbnail as Featured Image</h4>
<p>The plugin support you to set PDF as Featured Image. (v1.2 or later)<br />
Strictly explaining, when you set a PDF as Featured Image, the plugin automatically set the thumbnail which is registered with this PDF.<br />
You can call thumbnail by using get_the_post_thumbnail function.</p>
<pre><code>echo get_the_post_thumbnail ( $post->ID, 'medium' );
</code></pre>
<p>May you want pdf file from the post thumbnail.</p>
<pre><code>$thumb_id = get_post_thumbnail_id ( $post->ID );
$pdf_id = get_post( $thumb_id )->post_parent;
if ( $pdf_id && get_post_mime_type ( $pdf_id ) === 'application/pdf' ){
  $pdf = get_post($pdf_id);
  echo '<a class="link-to-pdf" href="'.wp_get_attachment_url($pdf_id).'" title="'.esc_html($pdf->post_title).'" target="_blank">'.get_the_post_thumbnail().'</a>'."\n";
}
</code></pre>
<h4>Display attachment data with in caption</h4>
<p>The plugin allows you to insert [caption] short-code into the post content area as when insert an image. If you want to display attachment title, description, file type, file size and so on, use img_caption_shortcode filter in your functions.php.<br />
Here’s an example code…<br />
    function add_attachment_data_in_caption( $empty, $attr, $content ) {<br />
        $attr = shortcode_atts( array( ‘id’=>”, ‘align’=>’alignnone’, ‘width’=>”, ‘caption’=>” ), $attr );<br />
        if ( 1 > (int) $attr[‘width’] || empty( $attr[‘caption’] ) ) return ”;<br />
        if ( $attr[‘id’] ) {<br />
            $attr[‘id’] = ‘id=”‘ . esc_attr( $attr[‘id’] ) . ‘” ‘;<br />
            $attachment_id = explode(‘_’, $attr[‘id’]);<br />
            $attachment_id = $attachment_id[1];// get attachment id<br />
            if( get_post_mime_type ( $attachment_id ) === ‘application/pdf’ ){<br />
                $attachment = get_post( $attachment_id );<br />
                $bytes = filesize( get_attached_file( $attachment->ID ) );<br />
                if ($bytes >= 1073741824) $bytes = number_format($bytes / 1073741824, 2). ‘ GB’;<br />
                elseif ($bytes >= 1048576) $bytes = number_format($bytes / 1048576, 2). ‘ MB’;<br />
                elseif ($bytes >= 1024) $bytes = number_format($bytes / 1024, 2). ‘ KB’;<br />
                elseif ($bytes > 1) $bytes = $bytes. ‘ bytes’;<br />
                elseif ($bytes == 1) $bytes = $bytes. ‘ byte’;<br />
                else $bytes = ‘0 bytes’;<br />
                $attr[‘caption’] =<br />
                  ‘title : ‘ .$attachment->post_title. ‘<br />‘ . // title<br />
                  ‘caption : ‘ .$attr[‘caption’]. ‘<br />‘ .// caption<br />
                  ‘size : ‘ .$bytes. ‘<br />‘ . // file size<br />
                  ‘filetype : ‘ .get_post_mime_type ( $attachment_id ). ‘<br />‘ . // file type<br />
                  ‘description : ‘ .$attachment->post_content. ‘<br />‘; // description<br />
            }<br />
        }</p>
<pre><code>    return 
      '<div ' .$attr['id']. 'class="wp-caption ' .esc_attr( $attr['align'] ). '" style="max-width: ' .( 10 + (int) $attr['width'] ). 'px;">' .
      do_shortcode( $content ). '<p class="wp-caption-text">' .$attr['caption']. '</p>' .

PDF Image Generator

Also ties in really nicely with the media uploader, the image is set as the 'icon' field of the attachment, as one would want. PS The feature for generating images for existing pdfs is at the bottom of the settings - scroll down to see (unlike me the first time)!

Super stuff. Works perfectly.

Very impressed with how quick and easy it was to get up and running with the generated pdf views.

Great Little Plugin

Generate automatically cover image of PDF by using ImageMagick. Allow user to insert PDF link with thumbnail into editor and set as Featured Image.
