PHP uses imagick to convert PDF to PNG

Requirements: Convert PDF to PNG via PHP PDF generates PNG images, which are generally used for online reading and browsing.

Implementation under Windows:

1. PHP DLL extension download address: http://valokuva.org/outside-blog-content/imagick-windows-builds/

2. There are different versions of DLL for PHP. Make sure it is the same version as yours.

3. Rename the downloaded DLL to php_imagick.dll (I downloaded php_imagick_dyn-Q16.dll) and then put Enter EXT in the PHP installation directory.

4. Modify php.ini and add "extension=php_imagick.dll" without double quotes!

5. After restarting apache, write phpinfo and search for the "imagick" keyword. If there is one, it means it is installed.

6. Finally, ghostscript.exe must be installed, otherwise an error will be reported. Download address: http://downloads.ghostscript.com/public/gs904w32.exe

7. Finally, execute the PHP script and modify it according to your needs.

Implementation under Linux:

1 Download ImageMagick-6.7.1-6

wget ftp://ftp.u-aizu.ac.jp/pub/graphics/image/ImageMagick/imagemagick.org/ImageMagick.tar.gz

2 Unzip

# tar -xzvf ImageMagick.tar.gz

3 Compile and install

# cd  ImageMagick-6.7.1-6 # ./configure -prefix=/usr/local/imagemagick -enable-lzw -with-modules && make && make install

4. Check it out

# /usr/local/imagemagick/bin/convert -version

5. Test it

# pwd /root/test/ImageMagick-6.7.1-6 # cd images/ # /usr/local/imagemagick/bin/convert -sample 25%x25% wizard.jpg test.jpg

6. Start installing the imagick PHP extension (Note: PHP >= 5.1.3 is required to install the imagick extension, ImageMagick > = 6.2.4)

7. Get imagick (get the latest version: http://pecl.php.net/package/imagick)

# wget http://pecl.php.net/get/imagick-3.1.0RC1.tgz
http://code.google.com/p/lnamp-web-server/downloads/detail?name=imagick-3.1.0b1.tgz&can=2&q=label%3Aimagick

8. Unzip

# tar -zxvf imagick-3.1.0RC1.tgz apt-get install php5-dev

9.phpize

# cd imagick-3.1.0RC1 # phpize

10. Configuration and compilation

# ./configure # make&&make install

Note: After successful compilation, imagick.so will be generated in the php extension directory, and then add "extension="/ in php.ini usr/lib/php5/20090626 lfs/imagick.so""

11. Restart apache

/etc/init.d/apache2 restart

12. You can also use PECL to install

1) sudo apt-get install libmagick-dev
2) sudo apt-get install php-pear php5-dev
3) sudo pecl install imagick

PHP code call:

function pdf2png($PDF,$Path){
   if(!extension_loaded('imagick')){
       return false;
   }
   if(!file_exists($PDF)){
       return false;
   }
   $IM = new imagick();
   $IM->setResolution(120,120);
   $IM->setCompressionQuality(100);
   $IM->readImage($PDF);
   foreach ($IM as $Key => $Var){
       $Var->setImageFormat('png');
       $Filename = $Path.'/'.md5($Key.time()).'.png';
       if($Var->writeImage($Filename) == true){
           $Return[] = $Filename;
       }
   }
   return $Return;
}
