CXXXI. PostScript document creation

Introduction

This module allows to create PostScript documents. It has many similarities with the pdf extension. Actually the API is almost identical and one can in many cases just replace the prefix of each function from pdf_ to ps_. This also works for functions which has no meaning in the PostScript document (like adding hyperlinks) but will have an effect if the document is converted to PDF.

Documents created by this extension are sometimes even superior to documents created with the pdf extension, because pslib's text rendering functions can handle kerning, hyphenation and ligatures which results in much better output of boxed text.

Requirements

You need at least PHP 4.3.0 and pslib >= 0.1.12. The ps library (pslib) is available at http://pslib.sourceforge.net/.

Installation

A short installation note: just type

$ pecl install ps

in your console.

Runtime Configuration

This extension has no configuration directives defined in php.ini.

Resource Types

This extension defines a PostScript document resource returned by ps_new().
