April 2012 Archives

Google just deprecated their image chart API that I use to create QR codes.  When I first looked into it a while ago, there wasn't a good solution that worked on the old Perl I was stuck with.   Now I'm all upgraded and looked again and found GD::Barcode::QRcode.  Works great.

This is pretty straight from the module's synopsis, but it took a second for me to get what I wanted, so I thought I'd post it.

# Create QR code with Perl

use strict;
use warnings;
use GD::Barcode::QRcode;

open my $OUT, '>', 'test.png';

my $gd = GD::Barcode::QRcode->new(
	{ Ecc => 'L', Version=>2, ModuleSize => 16},

print $OUT $gd->plot->png;
close $OUT;
