Struct ConvMarker 

pub struct ConvMarker<'a, ML: VertexSource, MS: VertexSource> { /* private fields */ }

Place marker shapes at positions along a path.

Takes a marker locator (which provides edge start/end vertex pairs) and marker shapes (which define the shape to place). Each marker is rotated to match the edge direction and optionally transformed.

Port of C++ conv_marker<MarkerLocator, MarkerShapes>.

Implementations

impl<'a, ML: VertexSource, MS: VertexSource> ConvMarker<'a, ML, MS>

pub fn new(marker_locator: &'a mut ML, marker_shapes: &'a mut MS) -> Self

pub fn transform(&self) -> &TransAffine

pub fn transform_mut(&mut self) -> &mut TransAffine

Trait Implementations

impl<ML: VertexSource, MS: VertexSource> VertexSource for ConvMarker<'_, ML, MS>

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.
