Question

What libraries, extensions etc. would be required to render a portion of a PDF document to an image file?

Most PHP PDF libraries that I have found center around creating PDF documents, but is there a simple way to render a document to an image format suitable for web use?

Our environment is a LAMP stack.

Answer 1

You need ImageMagick and GhostScript

<?php $im = new imagick('file.pdf[0]'); $im->setImageFormat('jpg'); header('Content-Type: image/jpeg'); echo $im; ?> 

The [0] means page 1.
