Struct RendererOutlineImage 

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

Image-patterned outline renderer.

Port of C++ renderer_outline_image<BaseRenderer, ImagePattern>. Renders anti-aliased lines using an image pattern sampled along the stroke.

The generic parameter P is the image line pattern type (e.g., LineImagePattern<PatternFilterBilinearRgba> or LineImagePatternPow2<PatternFilterBilinearRgba>).

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).
