    $plotter->scale;

    %params = (

    $plotter = SVG::Barcode::Subclass->new(%params);

DESCRIPTION

SVG::Barcode is a base class for SVG 1D and 2D codes.

You will not use it directly, it will be loaded by its subclasses:

CONSTRUCTOR

new

    $plotter = SVG::Barcode::Subclass->new;             # create with defaults
    $plotter = SVG::Barcode::Subclass->new(%params);

METHODS

plot

    $svg = $plotter->plot($text);

Creates a barcode.

PARAMETERS

background

    $value   = $plotter->background;
    $plotter = $plotter->background($newvalue);
    $plotter = $plotter->background('');          # white

Getter and setter for the background color. Default white.

class

    $value   = $plotter->class;
    $plotter = $plotter->class($newvalue);
    $plotter = $plotter->class('');          # ''

Getter and setter for the class of the svg element. Default ''.

foreground

    $value   = $plotter->foreground;
    $plotter = $plotter->foreground($newvalue);
    $plotter = $plotter->foreground('');          # black

Getter and setter for the foreground color. Default black.

height

    $value   = $plotter->height;
    $plotter = $plotter->height($newvalue);
    $plotter = $plotter->height('');          # ''

Getter and setter for the height of the svg element. Default ''.

id

    $value   = $plotter->id;
    $plotter = $plotter->id($newvalue);
    $plotter = $plotter->id('');          # ''

Getter and setter for the id of the svg element. Default ''.

margin

    $value   = $plotter->margin;
    $plotter = $plotter->margin($newvalue);
    $plotter = $plotter->margin('');          # 2

Getter and setter for the margin around the barcode. Default 2.

scale

    $value   = $plotter->scale;
    $plotter = $plotter->scale($newvalue);
    $plotter = $plotter->scale('');          # ''

Getter and setter for the scale of the svg element. Sets "width" and "height" to products of the width and height of the graphics. Used to display small barcodes without blur. Default ''.

width

    $value   = $plotter->width;
    $plotter = $plotter->width($newvalue);
