Struct piet_common::D2DRenderContext

pub struct D2DRenderContext<'a> { /* fields omitted */ }

Methods

impl<'b, 'a> D2DRenderContext<'a> where     'a: 'b,

pub fn new<RT>(     factory: &'a Factory,     dwrite: &'a Factory,     rt: &'b mut RT ) -> D2DRenderContext<'b> where     RT: RenderTarget,

Create a new Piet RenderContext for the Direct2D RenderTarget.

Note: the signature of this function has more restrictive lifetimes than the implementation requires, because we actually clone the RT, but this will likely change.

Trait Implementations

impl<'a> RenderContext for D2DRenderContext<'a>

type Point = Point2

The type of a 2D point, for this backend.

type Coord = f32
