=head1 NAME

GD::Barcode::Matrix2of5 - Create Matrix2of5 barcode image with GD

=head1 SYNOPSIS

I<ex. CGI>

use GD::Barcode::Matrix2of5;
  binmode(STDOUT);
  print "Content-Type: image/png\n\n";
  print GD::Barcode::Matrix2of5->new('1234567890')->plot->png;

I<with Error Check>

my $oGdBar = GD::Barcode::Matrix2of5->new('A12345678');
  die $GD::Barcode::Matrix2of5::errStr unless($oGdBar); #Invalid Characters
  $oGdBar->plot->png;

=head1 DESCRIPTION

GD::Barcode::Matrix2of5 is a subclass of GD::Barcode and allows you to
create Matrix2of5 barcode image with GD.

=head2 new

I<$oGdBar> = GD::Barcode::Matrix2of5->new(I<$sTxt>);

Constructor. 
Creates a GD::Barcode::Matrix2of5 object for I<$sTxt>.
I<$sTxt> has numeric characters([0-9]).

=head2 plot()

I<$oGd> = $oGdBar->plot([Height => I<$iHeight>, NoText => I<0 | 1>]);

creates GD object with barcode image for the I<$sTxt> specified at L<new> method.
I<$iHeight> is height of the image. If I<NoText> is 1, the image has no text image of I<$sTxt>.

ex.
  my $oGdB = GD::Barcode::Matrix2of5->new('12345678');
  my $oGD = $oGdB->plot(NoText=>1, Height => 20);
  # $sGD is a GD image with Height=>20 pixels, with no text.

=head2 barcode()

I<$sPtn> = $oGdBar->barcode();

returns a barcode pattern in string with '1' and '0'. 
'1' means black, '0' means white.

ex.
  my $oGdB = GD::Barcode::Matrix2of5->new('12345678');
  my $sPtn = $oGdB->barcode();

=head2 $errStr

$GD::Barcode::Matrix2of5::errStr

has error message.

=head2 $text

$oGdBar->{$text}

has barcode text based on I<$sTxt> specified in L<new> method.
