Project Description

Below you can see our the PHP code we use to convert one PDF file to one multipage PNG file. The library that is referenced can be found here (I think): [url removed, login to view]

Our problem is that we run on an EC2-micro instance with 600 mb of ram and on some files the resolution of the resulting PNG file is too low to be readable. If we increase the resolution parameters from 100 to 400 below, then it the process will often crash. I need someone who can fix this problem, either by fixing the code below or finding a different library to achieve the same thing. You will get access to our linux server.


$img_temp = $_POST['img_temp'];

$file_path = $_POST["file_path"];

$file_type = strtoupper(substr(strrchr($file_path, "."), 1));

$im = new Imagick();

$im->setresourcelimit(imagick::RESOURCETYPE_MEMORY, 32);

$im->setresourcelimit(imagick::RESOURCETYPE_MAP, 32);



$count = 1;

$num_image = $im->getNumberImages();

//convert each page

for ($x = 1;$x <= $num_image; $x++)



$im->setResolution(100, 100);


$im->readImage($file_path . "[" . ($x-1) . "]");

$im->writeImage($img_temp . '/img[' . $count . '].png');



echo "conversion successful";
