| Subject: | Warnings in GD::Barcode::QRcode with version > 1 |
Hallo
I am using GD::Barcode::QRcode 1.15 to encode urls. Whenever I use a version > 1 in strict mode, i.e. everytime for me, three warnings about uninitialized variables are issued.
For ex:
my $url = "http://www.google.com/";
my $qr = GD::Barcode::QRcode->new($url, { Ecc => 'L', ModuleSize => 4 })->plot->png;
logs:
Use of uninitialized value within @aMask in bitwise xor (^) at /usr/share/perl5/vendor_perl/GD/Barcode/QRcode.pm line 213.
Use of uninitialized value within @aMatrixX in array element at /usr/share/perl5/vendor_perl/GD/Barcode/QRcode.pm line 213.
Use of uninitialized value within @aMatrixY in array element at /usr/share/perl5/vendor_perl/GD/Barcode/QRcode.pm line 213.
For reference, line 213 for me is
$aCont[$aMatrixX[$iRemainBitTmp]][$aMatrixY[$iRemainBitTmp]]
= (255 ^ $aMask[$iRemainBitTmp] );
Just to know I applied the patch to enable version auto-select:
-$oSelf->{Version} = $rhPrm->{Version} || 1;
+$oSelf->{Version} = $rhPrm->{Version} || 0;
But I tried with fixed versions in new() parameters, with no luck.
I tried the new QRcode.pm module from the 1.99 develpment version, but nothing changed too.
Thanks , regards
Luigi
