NAME

HTML::Barcode::Code128 - Generate HTML representations of Code 128 barcodes

SYNOPSIS

Barcode::Code128 is required by this class, so please install it first.

  my $code = HTML::Barcode::Code128->new(text => 'MONKEY');
  print $code->render;

DESCRIPTION

This class allows you to easily create HTML representations of Code 128 barcodes.

Here is an example of a Code 128 barcode rendered with this module:

MONKEY

This requires Barcode::Code128. You may also use the character constants from this module in your text. Be sure to provide their full package name. For example:

  my $text = Barcode::Code128::FNC1 . '00000123455555555558';
  HTML::Barcode::Code128->new(text => $text)->render;

You can read more about Code 128 online (e.g. http://en.wikipedia.org/wiki/Code_128).

METHODS

new (%attributes)

Instantiate a new HTML::Barcode::Code128 object. The %attributes hash requires the "text" attribute, and can take any of the other attributes listed below.

render

This is a convenience routine which returns <style>...</style> tags and the rendered barcode.

If you are printing multiple barcodes or want to ensure your style tags are in your HTML headers, then you probably want to output the barcode and style separately with "render_barcode" and "css".

render_barcode

Returns only the rendered barcode. You will need to provide stylesheets separately, either writing them yourself or using the output of "css".

css

Returns CSS needed to properly display your rendered barcode. This is only necessary if you are using "render_barcode" instead of the easier "render" method.

ATTRIBUTES

These attributes can be passed to new, or used as accessors.

text

Required - The information to put into the barcode.

foreground_color

A CSS color value (e.g. '#000' or 'black') for the foreground. Default is '#000'.

background_color

A CSS color value background. Default is '#fff'.

bar_width

A CSS value for the width of an individual bar. Default is '2px'.

bar_height

A CSS value for the height of an individual bar. Default is '100px'.

show_text

Boolean, default true. Indicates whether or not to render the text below the barcode.

css_class

The value for the class attribute applied to any container tags in the HTML (e.g. table or div). td tags within the table will have either css_class_on or css_class_off classes applied to them.

For example, if css_class is "barcode", you will get <table class="barcode"> and its cells will be either <td class="barcode_on"> or <td class="barcode_off">.

embed_style

Rather than rendering CSS stylesheets, embed the style information in HTML style attributes. You should not use this option without good reason, as it greatly increases the size of the generated markup, and makes it impossible to override with stylesheets.
