28       $oGdBar = GD::Barcode::Matrix2of5->new($sTxt);
29
30       Constructor.  Creates a GD::Barcode::Matrix2of5 object for $sTxt.

34
35       $oGd = $oGdBar->plot([Height => $iHeight, NoText => 0  1]);
36
37       creates GD object with barcode image for the $sTxt specified at new

42         my $oGdB = GD::Barcode::Matrix2of5->new('12345678');
43         my $oGD = $oGdB->plot(NoText=>1, Height => 20);
44         # $sGD is a GD image with Height=>20 pixels, with no text.
45
46       barcode()
47
48       $sPtn = $oGdBar->barcode();
49
50       returns a barcode pattern in string with '1' and '0'.  '1' means black,
51       '0' means white.

54         my $oGdB = GD::Barcode::Matrix2of5->new('12345678');
55         my $sPtn = $oGdB->barcode();
56
57       $errStr
58
59       $GD::Barcode::Matrix2of5::errStr
60
61       has error message.
