writeImage with imagick in codeigniter

I'm using codeigniter and imagick for convert pdf to png image file.

$im = new imagick();
$im->setResolution ( 110,110);
$im->readImage($target_path);
$num_page = $im->getnumberimages();
for ($i=0; $i < $num_page ; $i++) { 
$im->readImage($target_path."[".$i."]");
$im->setImageFormat('png');
$im->writeImage(?);
}
$im->destroy();

I don't know how save this file in codeignietr_folder/assets/pdf-img
I tried ../../assets/test.png and localhost/codeignietr_folder/assets/pdf-img
but it doesn't work! how could i do it?

Solution

  • You can use $im->writeImage($file); where 

    $file = getcwd() . '/assets/pdf-img/test.png';
