thumber

Creates image thumbnails from PDF files.

Thumber generates thumbnails from your PDFs. You can call thumber using a single tag in your template.

Example usage:

{exp:thumber:create src='/uploads/documents/yourfile.pdf' page='2' extension='jpg' height='250' class='awesome' title='Click to download' link='yes'}

Parameters:

• src: The source PDF [Required]
• width: The width of the generated thumbnail [Default: 84]
• height: The height of the generated thumbnail [Default: 108]
• page: The page of the PDF used to generate the thumbnail [Default: 1]
• extension: The file type of the generated thumbnail [Default: png]
• link: Wrap the thumbnail in a link to the PDF [Default: no]
• crop: Where width and height are both specified, crop to preserve aspect ratio [Default: yes]

Any other parameters will be added to the img tag in the the generated html snippet – so if you want to add an id or class, just add them as parameters.

Requirements:

• This plugin requires ImageMagick (v6.3.8-2 or newer) and Ghostscript
• You must create a directory for your cached thumbnails to live. Thumber must have permissions to write to this directory. The default directory is specified as /images/thumber

### Todos:

• Automatically create required directories
• Improve caching (e.g. add an expiry time to cached images, and run a cache cleanup)
• Add more parameters, e.g. max_width, max_height
• Allow for tag pairs as well as single tags
• Generate thumbnails for remotely hosted PDFs
