Imager::QRCode - Generate QR Code with Imager using libqrencode
use Imager::QRCode; my $qrcode = Imager::QRCode->new( size => 2, margin => 2, version => 1, level => 'M', casesensitive => 1, lightcolor => Imager::Color->new(255, 255, 255), darkcolor => Imager::Color->new(0, 0, 0), ); my $img = $qrcode->plot("blah blah"); $img->write(file => "qrcode.gif") or die "Failed to write: " . $img->errstr; # or exporting function use Imager::QRCode qw(plot_qrcode); my $img = plot_qrcode("blah blah", \%params); $img->write(file => "qrcode.gif") or die "Failed to write: " . $img->errstr;
This module allows you to generate QR Code with Imager. This module use libqrencode '2.0.0' and above.
$qrcode = Imager::QRCode->new(%params);
The new() constructor method instantiates a new Imager::QRCode object. new() accepts the following parameters.
new()
size - Horizontal and vertical size of module(dot). Default is 4.
size
margin - Margin size of QR Code. Default is 3.
margin
level - Error correction level. Valid values are 'M', 'L', 'Q' or 'H'. Default is 'L'.
level
version - Version of the symbol. If specify '0', this module chooses the minimum version for the input data. Default is '0'.
version
mode - Encoding mode. Valid values are 'numerical', 'alpha-numerical', '8-bit' or 'kanji'. Default is '8-bit'.
mode
If not give casesensitive then should be given mode. If 'kanji' is given, characters will be encoded as Shift-JIS characters. If '8-bit' is given, all of non-alpha-numerical characters will be encoded as is. If you want to embed UTF-8 string, choose '8-bit'.
casesensitive
casesensitive - If your application is case-sensitive using 8-bit characters, set to '1'. Default is '0'.
$img = $qrcode->plot("blah blah");
Create a new QR Code image. This method returns Imager object plotted QR Code with the given text.
$text is input text. %params is same paramater as new().
