Graphics::Primitive::Driver::Cairo - Cairo backend for Graphics::Primitive
use Graphics::Primitive::Component; use Graphics::Primitive::Driver::Cairo; my $driver = Graphics::Primitive::Driver::Cairo->new; my $container = Graphics::Primitive::Container->new( width => 800, height => 600 ); my $black = Graphics::Primitive::Color->new(red => 0, green => 0, blue => 0); $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::Cairo->new( format => 'PDF' ); $driver->draw($container); $driver->write('/Users/gphat/foo.pdf');
This module draws Graphics::Primitive objects using Cairo.
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.
Set/Get the antialias mode of this driver. Options are default, none, gray and subpixel.
This driver's Cairo::Context object
Get the format for this driver.
Get/Set the surface on which this driver is operating.
Get the data in a scalar for this driver.
Write this driver's data to the specified file.
Returns two Rectangles that encloses the supplied text. The origin's x and y maybe negative, meaning that the glyphs in the text extending left of x or above y.
The first rectangle is the bounding box required for a container that wants to contain the text. The second box is only useful if an optional angle is provided. This second rectangle is the bounding box of the un-rotated text that allows for a controlled rotation. If no angle is supplied then the two rectangles are actually the same object.
If the optional angle is supplied the text will be rotated by the supplied amount in radians.
Returns a Graphics::Primitive::Driver::TextLayout for the supplied textbox.
Reset the driver.
Draws the specified component. Container's components are drawn recursively.
