Trait containing integration methods with cairo::Context.

Required methods

unsafe fn draw_from_gl(
    &self,
    surface: &Surface,
    source: i32,
    source_type: i32,
    buffer_scale: i32,
    x: i32,
    y: i32,
    width: i32,
    height: i32
)

Safety

It’s the responsibility of the caller to ensure that source is a valid GL resource.

fn set_source_rgba(&self, rgba: &RGBA)

fn set_source_pixbuf(&self, pixbuf: &Pixbuf, x: f64, y: f64)

fn add_rectangle(&self, rectangle: &Rectangle)

fn add_region(&self, region: &Region)
