How do I convert a PDF document to a preview image in PHP

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

You need ImageMagick and GhostScript   lt  php  im   new imagick  file pdf 0      im- gt setImageFormat  jpg    header  Content-Type  image jpeg    echo  im    gt    The  0  means page 1

You can also get the page count using    im- gt getNumberImages      Then you can can create thumbs of all the pages using a loop  eg     file pdf    x

Here is a simple class I ve written and used on a couple of projects   It just wraps imagick and handles writing each page out to disk   If anyone is still looking for an easy way to do this  this link might be helpful

For those who don t have ImageMagick for whatever reason  GD functions will also work  in conjunction with GhostScript  Run the ghostscript command with exec   to convert a PDF to JPG  and manipulate the resulting file with imagecreatefromjpeg     Run the ghostscript command    exec  gs -dSAFER -dBATCH -sDEVICE jpeg -dTextAlphaBits 4 -dGraphicsAlphaBits 4 -r300 -sOutputFile whatever jpg input pdf     To manipulate  create a new placeholder image   newimage   imagecreatetruecolor       and bring in the current image   image   imagecreatefromjpeg  whatever jpg    and then you can use imagecopyresampled   to change the size  or any number of other built-in  non-imagemagick commands

I m the author of PDFlib which is a GhostScript  wrapper for php  advantage of using this library is  it is already tested and it does not require ImageMagic   Always GhostScript commands are faster than ImageMagic when it comes to pdf so you should either go for a GhostScript wrapper or pure GhostScript commands   pdflib   new ImalH PDFLib PDFLib     pdflib- gt setPdfPath  pdf file path    pdflib- gt setOutputPath  folder path for images    pdflib- gt convert

Use the php extension Imagick  To control the desired size of the raster output image  use the setResolution function   lt  php      im   new Imagick     im- gt setResolution 300  300         set the resolution of the resulting jpg  im- gt readImage  file pdf 0           0  for the first page  im- gt setImageFormat  jpg    header  Content-Type  image jpeg    echo  im    gt     Extension on Paolo Bergantino his answer and Luis Melgratti his comment  You need to set the resolution before loading the image
