Struct ConvContour 

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

Contour converter: generates an offset contour from a closed polygon.

Trait Implementations

impl<VS: VertexSource> VertexSource for ConvContour<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.
