Struct LineAdaptor 

pub struct LineAdaptor { /* private fields */ }

Adaptor for a single line segment as a VertexSource.

Port of C++ agg::line_adaptor.

Implementations

impl LineAdaptor

pub fn new(x1: f64, y1: f64, x2: f64, y2: f64) -> Self

Create a new line adaptor.

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

Re-initialize with new coordinates.

Trait Implementations

impl VertexSource for LineAdaptor

fn rewind(&mut self, _path_id: u32)

Reset the vertex source to the beginning of the given path. path_id selects which sub-path to iterate (0 for the first/only path).

fn vertex(&mut self, x: &mut f64, y: &mut f64) -> u32

Return the next vertex. Writes coordinates to x and y, returns a path command. Returns PATH_CMD_STOP when iteration is complete.
