在Zend Framework 2中使用ZendPdf

Question

I'm trying to wrap my head around zend framework 2 and it's module system. I have the the skeleton application in the Getting Started guide working. I now want to use ZendPdf to load in an existing pdf file and work with it. I've done the following so far:

• downloaded and installed ZendPdf using composer to my skeleton app
• Added ZendPdf to my application_config.php
• Added a simple controller action to create a new ZendPdf class and load in a document
• I also created a view for the controller action.

When ever I call the action in the controller I get the following error

Fatal error: Uncaught exception 'Zend\ModuleManager\Exception\RuntimeException' with message 'Module (ZendPdf) could not be initialized

Obviously, from the error, I need to add zendpdf to the module_config.php so the ModuleManager can pick it up. This is were I get lost. I don't know how to configure zendpdf in the config file. This is what I have so far:

module.config in the Album Module

return array(
'controllers' => array(
    'invokables' => array(
        'Album\Controller\Album' => 'Album\Controller\AlbumController',
    ),
),
// Routes for 
'router' => array(
    'routes' => array(
        'album' => array(
            'type'    => 'segment',
            'options' => array(
                'route'    => '/album[/:action][/:id]',
                'constraints' => array(
                    'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                    'id'     => '[0-9]+',
                ),
                'defaults' => array(
                    'controller' => 'Album\Controller\Album',
                    'action'     => 'index',
                ),
            ),
        ),
    ),
),
'view_manager' => array(
    'template_path_stack' => array(
        'album' => __DIR__ . '/../view',
    ),
),
'zendpdf' => array() /* what to do here */
);

This is the controller action in my AlbumController

public function viewPdfAction()
{
  $pdf = ZendPdf::load('/tmp/pdf_report.pdf');
}

This is the application.config

<?php
   return array(
     'modules' => array(
       'Application',
       'Album',
       'AlbumRest',
       'ZendPdf'
     ),
     'module_listener_options' => array(
        'config_glob_paths'    => array(
        'config/autoload/{,*.}{global,local}.php',
     ),
      'module_paths' => array(
          './module',
          './vendor',
     ),
  ),
);

I've been reading the docs but am just not getting it. I need a push in the right direction.

Using clues from Andy this is what I found that worked.

Install ZendPdf via composer. Using composer will make ZF2 automatically auto-the library. below is the composer.json file that I used

{
    "repositories": [
      {
        "type": "composer",
        "url": "http://packages.zendframework.com/"
      }
    ],
    "name": "zendframework/skeleton-application",
    "description": "Skeleton Application for ZF2",
    "license": "BSD-3-Clause",
    "keywords": [
        "framework",
        "zf2"
    ],
    "homepage": "http://framework.zend.com/",
    "require": {
        "php": ">=5.3.3",
        "zendframework/zendframework": "2.*",
        "zendframework/zendpdf": "*"
    }
}

In your controller import the ZendPdf namespace

use ZendPdf\PdfDocument;

Then somewhere in a Controller action create a new pdf object and work with it

public funciton someAction()
{
     $pdf = PdfDocument::load('path/to/pdf');
}
