Struct SplineCtrl 

pub struct SplineCtrl { /* private fields */ }

Spline control rendered via AGG.

Renders 5 paths: background, border, curve, inactive points, active point.

Port of C++ spline_ctrl_impl / spline_ctrl<ColorT>.

Trait Implementations

impl Ctrl for SplineCtrl

fn num_paths(&self) -> u32

fn color(&self, path_id: u32) -> Rgba8

impl VertexSource for SplineCtrl

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.
