PHP uses ImageMagick to convert PDF to PNG

1. The DLL extension download address for implementing

PHP under Windows: http://valokuva.org/outside-blog-content/imagick-windows-builds/.

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

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

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

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

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

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

2. Implementation under Linux

1. Download ImageMagick-6.7.1-6 (the version must be accurate)

#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 (convert is installed under /usr/local/bin by default. The above command may prompt that the convert command cannot be found, so you can create a link to /usr/local/bin/convert under /usr/bin. :)

                                                                                                                                                            Start installing the PHP extension of imagick .4)

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

# cd /usr/bin
           
# ln -s /usr/local/bin/convert convert
           
# convert -version

8. Unzip

# 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

9. phpize

# tar -zxvf imagick-3.1.0RC1.tgz

Note: When running /usr/local/webserver/php/bin/phpize, the following appears:

# cd imagick-3.1.0RC1
           
# phpize (根据自己的路径来)

According to the online solution:

Configuring for: PHP Api Version: 20041225 Zend Module Api No: 20060613 Zend Extension Api No: 
       
220060519 Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF 
        
environment variable. Then, rerun this script.

10. Configuration and compilation

# cd /usr/src 
# wget http://ftp.gnu.org/gnu/m4/m4-1.4.9.tar.gz 
          
# tar -zvxf m4-1.4.9.tar.gz 
          
# cd m4-1.4.9
          
# ./configure && make && make install 
          
# cd ../ 
         
# wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.62.tar.gz 
          
# tar -zvxf autoconf-2.62.tar.gz 
          
# cd autoconf-2.62/ 
          
# ./configure && make && make install
          
或者
          
# yum install m4 yum install autoconf

11. Restart apache

#service httpd restart

Use PECL method to install

#./configure --with-php-config=/usr/local/php/bin/php-config --with-imagick=/usr/local/imagemagick
# make
# make install
可能会出错，因为版本升级，文件夹结构少许变动，我们创建一下软连接：
# ln -s /usr/local/imagemagick/include/ImageMagick-6 /usr/local/imagemagick/include/ImageMagick
若是报这样的错误：make: *** [imagick_file.lo] Error 1则定位PKG_CONFIG export PKG_CONFIG_PATH=/usr/local/imagemagick/lib/pkgconfig
#./configure --with-php-config=/usr/local/php/bin/php-config --with-imagick=/usr/local/imagemagick
注意：编译成功后会在php 扩展目录生成imagick.so，然后再php.ini里面 例如: /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/imagick.so
加上extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/imagick.so
注意版本问题：不然会报make: *** [imagick_class.lo] Error 1  等类似错误。

3. PHP code call

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