Basic rasterizer interface

Required Methods

fn name(&self) -> &str

Name of the rasterizer (useful for debugging)

fn mask( &self, path: &Path, tr: Transform, img: &mut dyn ImageMut<Pixel = Scalar>, fill_rule: FillRule )

Rasterize provided path as mask with transformation applied, and specified fill rule.

fn mask_iter( &self, path: &Path, tr: Transform, size: Size, fill_rule: FillRule ) -> Box<dyn Iterator<Item = Pixel> + '_>

Iterator over rasterized mask pixels

This iterator should never return pixels outside of provided size region

Provided Methods

fn fill( &self, path: &Path, tr: Transform, fill_rule: FillRule, paint: &dyn Paint, img: &mut dyn ImageMut<Pixel = LinColor> )

Fill path with the provided paint
