How to convert .pdf file to .png using Imagemagick PHP API

Question

I want to convert .pdf file to .png file using Imagemagick php API.

we can do this from shell using this:

$convert sample.pdf sample_image.png

we can issue this command using php exec() function but due to some reason (security) I disabled the execution of shell commands using php.

so now tell me the solution that how can i convert my .pdf file to .png file without using the php exec() function?

There is another discussion about this here but it's not very clear.

Answer 1

you must have installed php5-imagick

$myurl = 'filename.pdf['.$pagenumber.']';
$image = new Imagick($myurl);
$image->setResolution( 300, 300 );
$image->setImageFormat( "png" );
$image->writeImage('newfilename.png');
