Struct nanovg::Context

pub struct Context(_);

A initialized NanoVG context - the central type which all operations rely on.

Methods

impl Context

pub fn raw(&self) -> *mut NVGcontext

Return the raw FFI C-struct pointer to the context.

pub fn frame<'a, F: FnOnce(Frame<'a>)>(     &'a self,     (width, height): (f32, f32),     device_pixel_ratio: f32,     handler: F )

Begin drawing a frame. All NanoVG drawing takes place within a frame.

width and height should be the width and height of the framebuffer / window client size. device_pixel_ratio defines the pixel ratio. NanoVG doesn't guess this automatically to allow for Hi-DPI devices. Basically, this is your hidpi factor. handler is the callback in which you draw your paths. You cannot draw paths outside of this callback.
