Struct ConvDash 

pub struct ConvDash<VS: VertexSource> { /* private fields */ }

Dash converter: generates a dashed line from a continuous center-line path.

Port of C++ conv_dash<VertexSource>.

Implementations

impl<VS: VertexSource> ConvDash<VS>

pub fn dash_start(&mut self, ds: f64)

pub fn set_shorten(&mut self, s: f64)

pub fn shorten(&self) -> f64

pub fn source(&self) -> &VS

pub fn source_mut(&mut self) -> &mut VS

Trait Implementations

impl<VS: VertexSource> VertexSource for ConvDash<VS>

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.
