Struct RendererOutlineAa 

pub struct RendererOutlineAa<'a, PF: PixelFormat> { /* private fields */ }

Anti-aliased outline renderer.

Port of C++ renderer_outline_aa<BaseRenderer>. Renders anti-aliased lines using a distance interpolation technique with configurable width profile.

Implementations

impl<'a, PF: PixelFormat> RendererOutlineAa<'a, PF>

where PF::ColorType: Default + Clone,

pub fn new(ren: &'a mut RendererBase<PF>, profile: &'a LineProfileAa) -> Self

pub fn ren(&self) -> &RendererBase<PF>

pub fn set_color(&mut self, c: PF::ColorType)

pub fn color(&self) -> &PF::ColorType

pub fn subpixel_width(&self) -> i32

pub fn set_clip_box(&mut self, x1: f64, y1: f64, x2: f64, y2: f64)

pub fn reset_clipping(&mut self)

pub fn line0(&mut self, lp: &LineParameters)

Render a simple line (no joins).

pub fn line1(&mut self, lp: &LineParameters, sx: i32, sy: i32)

Render line with start join.

pub fn line2(&mut self, lp: &LineParameters, ex: i32, ey: i32)

Render line with end join.

pub fn line3(&mut self, lp: &LineParameters, sx: i32, sy: i32, ex: i32, ey: i32)

Render line with both joins.

pub fn semidot<F: Fn(i32) -> bool>( &mut self, cmp: F, xc1: i32, yc1: i32, xc2: i32, yc2: i32, )

Render a semi-circular dot (for round caps). Port of C++ semidot.

pub fn pie(&mut self, xc: i32, yc: i32, x1: i32, y1: i32, x2: i32, y2: i32)

Render a pie slice (for round joins between two line segments). Port of C++ pie.

Trait Implementations

impl<'a, PF: PixelFormat> OutlineAaRenderer for RendererOutlineAa<'a, PF>

where PF::ColorType: Default + Clone,

fn accurate_join_only(&self) -> bool

Returns true if this renderer only supports accurate (miter) joins. Image pattern renderers return true; solid AA renderers return false.

fn line0(&mut self, lp: &LineParameters)

Render a simple line segment (no join information).

fn line1(&mut self, lp: &LineParameters, sx: i32, sy: i32)

Render a line segment with start join bisectrix.

fn line2(&mut self, lp: &LineParameters, ex: i32, ey: i32)

Render a line segment with end join bisectrix.

fn line3(&mut self, lp: &LineParameters, sx: i32, sy: i32, ex: i32, ey: i32)

Render a line segment with both start and end join bisectrices.

fn semidot( &mut self, cmp: fn(i32) -> bool, xc1: i32, yc1: i32, xc2: i32, yc2: i32, )

Render a semi-circular dot (for round caps).

fn pie(&mut self, xc: i32, yc: i32, x1: i32, y1: i32, x2: i32, y2: i32)

Render a pie slice (for round joins).
