This Library helps to convert any PDF file to an Image
You should have Imagick and Ghostscript installed.
- Install Ghostscript
sudo apt-get install -y ghostscript
composer require org_heigl/ghostscript
See issues regarding Ghostscript.
- Install ImageMagick
sudo apt-get install php-common gcc
sudo apt-get install imagemagick
sudo apt-get install php-imagick
See issues regarding ImageMagick.
- Make a directory name like
Libraries
under the LaravelApp
folder - Now Copy & Paste
Libraries/PdfToImage.php
to LaravelApp/Libraries/
folder
Converting a pdf to an image is easy.
$pdf = new \App\Libraries\PdfToImage($pathToPdf);
$pdf->saveImage($pathToWhereImageShouldBeStored);
Converting a multi pages pdf to multiple images
$path = storage_path() . "/app/public/documents/pdf_name.pdf";
$savePath = storage_path() . "/app/public/documents/pages/";
$pdf = new \App\Libraries\PdfToImage($path);
foreach (range(1, $pdf->getNumberOfPages()) as $pageNumber) {
$pageName = 'page_no'.'_'.$pageNumber;
$pdf->setPage($pageNumber)->saveImage($savePath.$pageName);
}
If the path you pass to saveImage
has the extensions jpg
, jpeg
, or png
the image will be saved in that format.
Otherwise the output will be a jpeg
.
You can get the total number of pages in the pdf:
$pdf->getNumberOfPages(); //returns an int
By default the first page of the pdf will be rendered. If you want to render another page you can do so:
$pdf->setPage(2)
->saveImage($pathToWhereImageShouldBeStored); //saves the second page
You can override the output format:
$pdf->setOutputFormat('png')
->saveImage($pathToWhereImageShouldBeStored); //the output wil be a png, no matter what
You can set the quality of compression from 0 to 100:
$pdf->setCompressionQuality(100); // sets the compression quality to maximum
If an error occur due to ImageMagick file reading from source like below
not authorized
This can be fixed by updating the ImageMagick policies. To do so, Open the policy file from /etc/ImageMagick-6/policy.xml
and add the below lines of PDF permission to read|write
<policy domain="coder" rights="read|write" pattern="PDF,PS" />
Restart Apache server if running on it
sudo systemctl restart apache2
This package uses Ghostscript through Imagick. For this to work Ghostscripts gs
command should be accessible from the PHP process. For the PHP CLI process (e.g. Laravel's asynchronous jobs, commands, etc...) this is usually already the case.
However for PHP on FPM (e.g. when running this package "in the browser") you might run into the following problem:
Uncaught ImagickException: FailedToExecuteCommand 'gs'
This can be fixed by adding the following line at the end of your php-fpm.conf
file and restarting PHP FPM. If you're unsure where the php-fpm.conf
file is located you can check phpinfo()
. If you are using Laravel Valet the php-fpm.conf
file will be located in the /usr/local/etc/php/YOUR-PHP-VERSION
directory.
env[PATH] = /usr/local/bin:/usr/bin:/bin
This will instruct PHP FPM to look for the gs
binary in the right places.
