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
<?php
$im = new imagick('file.pdf[0]');
$im->setImageFormat('jpg');
header('Content-Type: image/jpeg');
echo $im;
?>
The [0] means page 1.
You can also get the page count using
$im->getNumberImages();
Then you can can create thumbs of all the pages using a loop, eg.
'file.pdf['.$x.']'
I install finished! It's worked!
You may be do base install imagemagick on windows.
In php (local) use call exec(<command line>)
ex:
<?php
$pdf = "filename.pdf";
$info = pathinfo($pdf);
$file_name = basename($pdf,'.'.$info['extension']);
echo $file_name;
$pdf = "filename.pdf[0]";
exec("convert $pdf convert-img/$file_name.jpg");
?>
Besides, you may be use class imagick in PHP Imagick class
Thanks all helped me!
