Imagick 无法读取 PDF 文件

Question

I'm using Imagick and trying to convert a pdf to a png. It fails. My error_log says "Failed to read the file".

Example code:

$fileone =  $_SERVER['DOCUMENT_ROOT'] . '/' . 'test.pdf';
$image = new Imagick($fileone);
$image->readImage($fileone);
$image->thumbnailImage(300, 0);
echo '<img src="data:image/png;base64,' .  base64_encode($image->getimageblob())  . '" />';

Thoughts?

Answer 1

你需要安装ghostscript

sudo apt-get install ghostscript

Answer 2

I would first use realpath() to check your file path and then see if the file is readable.

$fileone = realpath('test.pdf');

if (!is_readable($fileone)) {
    echo 'file not readable';
}

Then if it is a multiple page pdf try this

$image = new Imagick($fileone.'[0]');
