NAME ^

Graphics::Primitive::Driver::CairoPango - Cairo/Pango backend for Graphics::Primitive

SYNOPSIS ^

    use Graphics::Pritive::Component;
    use Graphics::Pritive::Component;
    use Graphics::Primitive::Driver::CairoPango;

    my $driver = Graphics::Primitive::Driver::CairoPango->new;
    my $container = Graphics::Primitive::Container->new(
        width => $form->sheet_width,
        height => $form->sheet_height
    );
    $container->border->width(1);
    $container->border->color($black);
    $container->padding(
        Graphics::Primitive::Insets->new(top => 5, bottom => 5, left => 5, right => 5)
    );
    my $comp = Graphics::Primitive::Component->new;
    $comp->background_color($black);
    $container->add_component($comp, 'c');

    my $lm = Layout::Manager::Compass->new;
    $lm->do_layout($container);

    my $driver = Graphics::Primitive::Driver::CairoPango->new(
        format => 'PDF'
    );
    $driver->draw($container);
    $driver->write('/Users/gphat/foo.pdf');

DESCRIPTION ^

This module draws Graphics::Primitive objects using Cairo and Pango. This is a separate distribution due to the Pango requirement. The Pango specific bits will be rolled into the normal Cairo driver at some point.

IMPLEMENTATION DETAILS ^

Borders

Borders are drawn clockwise starting with the top one. Since cairo can't do line-joins on different colored lines, each border overlaps those before it. This is not the way I'd like it to work, but i'm opting to fix this later. Consider yourself warned.

METHODS ^

Constructor

new

Creates a new Graphics::Primitive::Driver::CairoPango object. Requires a format.

  my $driver = Graphics::Primitive::Driver::CairoPango->new(format => 'PDF');

Instance Methods

antialias_mode

Set/Get the antialias mode of this driver. Options are default, none, gray and subpixel.

cairo

This driver's Cairo::Context object

data

Get the data in a scalar for this driver.

draw

Draws the specified component. Container's components are drawn recursively.

format

Get the format for this driver.

get_textbox_layout ($font, $textbox)
