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

    $plotter->foreground;    # black

# DESCRIPTION

[SVG::Barcode](https://metacpan.org/pod/SVG%3A%3ABarcode) is a base class for SVG 1D and 2D codes.

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

- [SVG::Barcode::Code128](https://metacpan.org/pod/SVG%3A%3ABarcode%3A%3ACode128)

- [SVG::Barcode::DataMatrix](https://metacpan.org/pod/SVG%3A%3ABarcode%3A%3ADataMatrix)

- [SVG::Barcode::QRCode](https://metacpan.org/pod/SVG%3A%3ABarcode%3A%3AQRCode)

# CONSTRUCTOR

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);

## scale

    $value   = $plotter->scale;

    $plotter = $plotter->scale($newvalue);

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

Getter and setter for the scale of the svg element.  Sets ["width"](#width) and ["height"](#height) to products of

the width and height of the graphics.  Used to display small barcodes without blur.  Default `''`.

## width
