Struct scribl_curves::StrokeSeq

pub struct StrokeSeq { /* fields omitted */ }

A StrokeSeq is a sequence of strokes, each of which is a continuous curve. Each stroke can have its own style (thickness, color, effects). The strokes in a StrokeSeq are non-decreasing in time: one stroke ends before another begins.

Implementations

impl StrokeSeq

pub fn new() -> StrokeSeq

pub fn is_empty(&self) -> bool

pub fn first_time(&self) -> Time

Returns time at which the first segment in the first stroke was drawn. Panics if this sequence is empty.

pub fn last_time(&self) -> Time

Returns time at which the last segment in the last stroke was drawn. Panics if this sequence is empty.

pub fn append_stroke(
    &mut self,
    stroke: StrokeInProgress,
    style: StrokeStyle,
    distance_threshold: f64,
    angle_threshold: f64
)

Appends a StrokeInProgress to this stroke sequence.

distance_threshold and angle_threshold are parameters that control the simplification and smoothing that we apply to the incoming points.

Panics

Panics if stroke starts before the last existing stroke ends.

pub fn strokes<'a>(&'a self) -> impl Iterator<Item = StrokeRef<'a>> + 'a

Returns an iterator over all the strokes in this sequence.

pub fn render(&self, ctx: &mut impl RenderContext, time: Time)

Renders the part of this stroke sequence that is visible at time time.
