PDF thumbnail generation for Craft CMS 3 and Craft CMS 4

The craft.PDFThumb.thumbnail() template tag returns a URL to the generated thumbnail.

{% for myAsset in item.assetRef %}
    <img src="{{ craft.PDFThumb.thumbnail(myAsset) }}">
    <img src="{{ craft.PDFThumb.thumbnail(myAsset, 100, 100) }}">
    <img src="{{ craft.PDFThumb.thumbnail(myAsset, 100, 150, true, 'jpg') }}">
{% endfor %}

PThumb is a Craft plugin that generates thumbnail preview images for PDF documents. It's easy to drop into your templates, requires only the commmand-line version of ImageMagick (not the PHP bindings), and caches the generated thumbnails.

It's still very much a work in progress, so use it in production environments at your own risk.

1. Download the ZIP file
2. Unzip it and move the pthumb folder to craft/plugins
3. Install the plugin from the Plugins page of your control panel
4. Click on the PThumb link on the plugins page to configure the plugin

The craft.PThumb.thumbnail() template tag returns a URL to the generated thumbnail.

<img src="{{ craft.PThumb.thumbnail(myAsset) }}">
<img src="{{ craft.PThumb.thumbnail(myAsset, 100, 100) }}">
<img src="{{ craft.PThumb.thumbnail(myAsset, 100, 150, true, 'jpg') }}">

The arguments, in order, are:

• Files must be limited to a single directory
• Files must be stored locally
