NAME
    Acme::Odometer - Create graphical web counters

VERSION
    version 0.0.4

SYNOPSIS
        # write the image to a file for your viewing pleasure
        use Acme::Odometer;
        use File::Slurp qw( write_file );

        my $odometer = Acme::Odometer->new(
            asset_path     => 'path/to/digit/files',
            file_extension => 'png',
        );

        my $image = $odometer->image( '000123456789' );

        # write as a GIF
        write_file( "counter.gif", $image->gif );

        # write as a PNG
        write_file( "counter.png", $image->png );


        # or (for example) in a Dancer app
        # place an odometer graphic at /counter?count=12345
        # in real life, you'll want to validate etc before creating the graphic

        get '/counter' => sub {
            header( 'Content-Type' => 'image/png' );
            my $odometer = Acme::Odometer->new(
                asset_path     => 'path/to/digit/files',
                file_extension => 'png',
            );
            $odometer->image( params->{count} )->png;
        };

DESCRIPTION
    This is a BETA release. The interface is still subject to change.

    Acme::Odometer makes it easy to produce graphical web counters. You
    know, those odometer style thingies you used to see on a lot of
    geocities pages? This module takes a bunch of images of different
    digits, strings them together and passes them back to you as a GD::Image
    object.

CONSTRUCTOR AND STARTUP
  new()
    Creates and returns a new Acme::Odometer object. The following
    parameters can be passed to new().

    *   "asset_path => "/path/to/odometer/files""

        The path to your asset folder. The asset folder will contain 0..9
        image files of equal width, named 0.gif, 1.gif, 2.gif, 3.gif etc.
        The images can be in any format which GD can read. This parameter is
        required.

    *   "file_extension => 'png'"

        The extension of the files in your asset directory: "gif", "GIF",
        "png", "jpg", "jpeg", etc. This module makes no assumptions about
        what is or is not a valid extension. This parameter is optional and
        defaults to "gif".

            my $odometer = Acme::Odometer->new(
                asset_path     => 'path/to/digit/files',
                file_extension => 'png',
            );

  image
    Returns a GD::Image object, which you can use to print your image

        my $odometer = Acme::Odometer->new(
            asset_path     => 'path/to/digit/files',
            file_extension => 'png',
        );

        binmode STDOUT;
        print $odometer->image->png;

RESOURCES
    All you need to get started is the images, which should consist of the
    digits 0-9, all in the same file format and all of equal width. For
    example, see <http://digitmania.birdbrain.net/> for a bunch of insanely
    retro counter graphics. Or, see the assets folder of this distribution
    for a basic odometer.

ACKNOWLEDGEMENTS
    It's hard to trace the history of a lot of web counter graphics which
    have been circulated as they seem to originate in the Wild West of the
    internet. The images bundled with this dist appear to have been created
    by Heini Withagen, but this is hard to verify since the original page
    404s now and also 404s in the earliest wayback machine snapshot (1999).
