- What is object-oriented Perl? Object-oriented Perl is a small amount of additional syntax and semantics, added to the existing imperative features of the Perl programming language. Those extras allow regular Perl packages, variables, and subroutines to behave like classes, objects, and methods.
- I will test later with a smaller pdf file. If that works, I just create for each comic book several pdf files, each file containing several pages of the book. Perl and PDF related.

Perl XML::LibXML by Example Documentation, Release TheXML::LibXMLPerl module is a wrapper around thelibxml2parser library which is written in C. This tutorial uses example code to introduce the features of XML::LibXML and the ways in which you can use the module. The example scripts and XML documents are available as a ZIP file download. (described in Chapter8). In addition to the Perl wrapper described in this chapter, Ming comes with interfaces to PHP, Python, Ruby, Java, and C. The Ming library was created by Dave Hayden of Opaque Industries and is released under the LGPL (Lesser GNU Public License). Most web-graphics designers create SWF files with Macromedia's Flash. Essential Perl Page: 1 Essential Perl This document is a quick introduction to the Perl language. Perl has many features, but you can get pretty far with just the basics, and that's what this document is about.
I've long been a user of PDF::API2, a module available for Perl. I use it everyday at work and along with a few other modules, it has made Perl an invaluable tool for me. Being able to generate PDF's for reports and documents allow for a bevy of automation shortcuts where traditional Data Merging, or 'variable imaging,' would be impractical and at times impossible to integrate into existing e-commerce or ERP platforms.
To run this code on your own computer, you will need to download a Perl interpreter. If you're on Windows, I would recommend http://strawberryperl.com/.
Simple Letter sized PDF
Add a picture and text
JPEGs are supported as well as PNGs with transparency.
The example below has no image formatting, but the back-end Perl script for this example does center the image and size it down to fit, but that's outside the scope of this simple example.
Add content to an existing PDF document
This is great for automating online forms for customers to fill out on your website that can then be used for printing, record-keeping, or emailing to other parties.
In this example, Page 1 of the IRS 1040 form is opened and a persons first and last names are filled in and saved as a new document. How do i download java for mac.
A custom font file, Raleway, is also used.
Drawing lines
Basic shapes and lines are possible through the ‘gfx' object. Here, the first four lines define the line, and the last line actually draws the line.
Barcodes
This really isn't an example of PDF::API2, but rather an example of how existing Perl tools can be used to create custom documents. Here, the module ‘GD::Barcode::Code39' is used to encode a custom string into a standard ‘3 of 9' type barcode.
GD::Barcode::Code39 itself will only produce the 1's and 0's necessary for the barcode. A ‘foreach' loop then iterates through the binary string and PDF::API2 will be used to draw either a black line (#000000) or a white line (#ffffff), producing a barcode.

You can download an app for your phone to scan the barcode. Read the CODE39 Wikipedia page for valid characters and more information.

QR Code
This one comes in handy a lot. Be careful with your 'Version=>?' numbers. QR Codes will encode up to a certain number of bits depending on this version number. The example below is 'Version=>4' which will hold up to 512 bits.
Exceeding the number of bits will error out, but the 'GD::Barcode::QRcode' module has a bug that prevents handling the error cleanly. Gmail password hack for mac download. Read more.
