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.
   
  A short installation note: just type
  
  in your console. 
 
This extension has no configuration directives defined in php.ini.
The constants below are defined by this extension, and
will only be available when the extension has either
been compiled into PHP or dynamically loaded at runtime.
  The following two tables lists all constants defined by the ps extension.
  
Table 1. Contants for line caps
| Name | Meaning | 
|---|
| ps_LINECAP_BUTT |  | 
| ps_LINECAP_ROUND |  | 
| ps_LINECAP_SQUARED |  | 
Table 2. Contants for line joins
| Name | Meaning | 
|---|
| ps_LINEJOIN_MITER |  | 
| ps_LINEJOIN_ROUND |  | 
| ps_LINEJOIN_BEVEL |  |
