Catalyst::View::PDF::API2 - Create PDF files from Catalyst using Template Toolkit templates


Version 0.02


Create a PDF::API2 view:

 script/myapp_create.pl view PDF PDF::API2

In MyApp.pm, add a configuration item for the template include path:

 __PACKAGE__->config('View::PDF' => {
   INCLUDE_PATH => __PACKAGE__->path_to('root','pdf_templates')

In your controller:

 $c->stash->{pdf_template} = 'hello_pdf.tt';

In root/templates/hello_pdf.tt:

 [% pdf.corefont('Helvetica-Bold') %]


Catalyst::View::PDF::API2 provides the facility to generate PDF files from a Catalyst application by embedding PDF::API2 commands within a Template Toolkit template.

Template Syntax

Within your template you will have access to a pdf object which has methods corresponding to all of PDF::API2's functions.

For example, to print the text Hello, World at PDF coordinates 100,100, use the following directive in your template:

 [% f1 = pdf->corefont('Helvetica') %]
 [% page = pdf.page %]
 [% page.mediabox(595,842) %]
 [% text = page.text %]
 [% text.textlabel(50,800,$f1,20,'Hello, World',-hspace=>75) %]

Data held in the stash can be printed as follows:

 $c->stash->{list} = ['one', 'two', 'three', 'four'];

 [% y = 500 %]
 [% FOREACH item IN list %]
   [% page.textlabel(100,y,$f1,20,item) %]  ###### to fix
   [% y = y - 13 %]
 [% END %]
Formatting can be defined using the Template Toolkit format plugin:

 [% USE format %]
 [% currency = format('£%.2f') %]
 [% page.textlabel(100,100,$f1,20,currency(10)) %]

Using existing PDF documents

The key benefit of PDF::API2 is the ability to load an existing PDF file and use this as the basis for a new document.

For example, to produce receipts or shipping labels you could create a blank receipt in Microsoft Word, convert this to PDF, then use PDF::API2 to add in details such as the order number and customer address.

 [% page.textlabel(123,643,$f1,12,order.number) %]
 [% page.textlabel(299,643,$f1,12,order.date) %]

Note that the PDF document loaded by pdf.prForm must be in the same directory as your Template Toolkit template.



Render the PDF file, places the contents in $c->response->body and sets appropriate HTTP headers.

You should normally not need to use this method directly, instead forward to the PDF::API2 view from your controller:


The filename and content disposition (inline or attachment) can be controlled by putting the following values in the stash:

 $c->stash->{pdf_disposition} = 'attachment';  # Default is 'inline'
 $c->stash->{pdf_filename}    = 'myfile.pdf';  

If the PDF filename is not specified, it will be set to the last component of the URL path, appended with '.pdf'. For example, with a URL of http://localhost/view/order/pdf/1234 the PDF filename would be set to 1234.pdf.


Renders the PDF file and returns the raw PDF data.

If you need to capture the PDF data, e.g. to store in a database or for emailing, call render_pdf as follows:

 my $pdf = $c->view("PDF::API2")->render_pdf($c);
