[−][src]Struct piet_cairo::CairoRenderContext
Methods
impl<'a> CairoRenderContext<'a>[src]
pub fn new(ctx: &mut Context) -> CairoRenderContext[src]
Create a new Cairo back-end.
At the moment, it uses the "toy text API" for text layout, but when we change to a more sophisticated text layout approach, we'll probably need a factory for that as an additional argument.
Trait Implementations
impl<'a> RenderContext for CairoRenderContext<'a>[src]
type Point = Vec2
Cairo mostly uses raw f64, so this is as convenient as anything.
type Coord = f64
The type of 1D measurements, for example stroke width. Read more
type Brush = Brush
The type of a "brush". Read more
type Text = CairoText
An associated factory for creating text layouts and related resources.
type TextLayout = CairoTextLayout
type Image = ImageSurface
The associated type of an image.
