NAME

Catalyst::View::GD::Barcode::QRcode - GD::Barcode::QRcode View Class

SYNOPSIS

Create a View class using the helper

script/myapp_create.pl view QRcode GD::Barcode::QRcode

Configure variables in your application class

package MyApp;

MyApp->config(
    'View::QRcode' => {
        ecc         => 'M',
        version     => 4,
        module_size => 1,
        img_type    => 'png'
    },
);

Or using YAML config file

View::QRcode:
    ecc: 'M'
    version: 4
    module_size: 1
    img_type: 'png'

Add qrcode action to forward to the View on MyApp::Controller::Root

sub qrcode : Local {
    my ( $self, $c ) = @_;
    $c->stash->{qrcode} = 'http://www.cpan.org';
    $c->forward( $c->view( 'QRcode' ) );
}

Or change configuration dynamically

sub qrcode : Local {
    my ( $self, $c ) = @_;
    $c->stash( 
        qrcode => 'http://www.cpan.org', 
        qrcode_conf => {
            ecc         => 'Q',
            version     => 5,
            module_size => 3,
            img_type    => 'gif',
        },
    );

    $c->forward( $c->view( 'QRcode' ) );
}

If you use 'Catalyst::Plugin::DefaultEnd', in your application class

sub qrcode : Local {
    my ( $self, $c) = @_;

    $c->stash->{qrcode} = 'http://www.cpan.org';
}

sub end : Private {
    my ( $self, $c ) = @_;
    $c->forward( $c->view( 'QRCode' ) ) if $c->stash->{qrcode};
    $self->NEXT::end( $c );
}

Or with 'Catalyst::Action::RenderView'

sub render : ActionClass('RenderView') {}

sub end : Private {
    my ( $self, $c ) = @_;
    
    $c->detach( $c->view( 'QRCode' ) ) if $c->stash->{qrcode};
    $c->forward('render');
}

Then you can get QRcode image from http://localhost:3000/qrcode

For Template::Toolkit

<img src="[%c.uri_for('/qrcode') %]"/>
