Make a PNG image containing a QR code from text
This module converts input text to a PNG image of a QR code containing the text. The PNG image can either be stored to a file or it can be a scalar.
ImagePNGLibpng requires “libpng” to be installed. “libpng” should already be installed on most Linux and Windows systems.
This example makes a data URL QR code
use ImagePNGQRCode ‘qrpng’;
use URI;
my $data = ‘abcdefghijklmnopqrstuvwxyz’;
my $u = URI->new ‘data’;
$u->media_type ‘image/png’;
$u->data qrpng text => $data;
print “\n”;
