GD::Barcode::Matrix2of5 is a subclass of GD::Barcode and allows you to create Matrix2of5 barcode image with \s-1GD\s0.

new

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

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

\fIplot()\fP

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

creates \s-1GD\s0 object with barcode image for the $sTxt specified at new method. $iHeight is height of the image. If NoText is 1, the image has no text image of $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.

\fIbarcode()\fP

$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(); $GD::Barcode::Matrix2of5::errStr

has error message. $oGdBar->{$text}

has barcode text based on $sTxt specified in new method.
