NAME

PostScript::Barcode - barcode writer

VERSION

This document describes PostScript::Barcode version 0.001.

SYNOPSIS

    # This is abstract, do not use directly.

DESCRIPTION

By itself alone, this role does nothing useful. Use one of the classes residing under this namespace.

INTERFACE

Attributes

data

Type Str, required attribute, data to be encoded into a barcode.

pack_data

Type Bool, whether data is encoded into PostScript hex notation. Default is true.

move_to

Type ArrayRef[Num], position where the barcode is placed initially. Default is [0, 0], which is the lower left hand of a document.

translate

Type ArrayRef[Num], vector by which the barcode position is shifted.

scale

Type ArrayRef[Num], vector by which the barcode is resized.

bounding_box

Type ArrayRef[Num], coordinates of the EPS document bounding box.

Methods

post_script_source_code

Returns EPS source code of the barcode as string.

render

    $barcode->render(-sDEVICE => 'pnggray', -sOutputFile => 'out.png',);

Takes a hash of initialisation options, see "init_with_args" in GSAPI and http://ghostscript.com/doc/current/Use.htm#Invoking. Default is qw(-dBATCH -dEPSCrop -dNOPAUSE -dQUIET -dSAFER -dGraphicsAlphaBits=4 -dTextAlphaBits=4 -sDEVICE=pngalpha -sOutputFile=-), meaning the barcode is rendered as transparent PNG with anti-aliasing to STDOUT.
