Expand description

Geometry utilities for carving horizontal text slots from exclusion shapes.

Implementations§

Source§

impl ObstacleLayoutHelper

Source

pub fn carve_text_line_slots( base_slot: Interval, blocked: impl IntoIterator<Item = Interval>, min_slot_width: f64, ) -> Vec<Interval>

Carve all blocked intervals, then discard slots narrower than the minimum. The surviving intervals remain ordered from left to right.

Source

pub fn circle_interval_for_band( cx: f64, cy: f64, radius: f64, band_top: f64, band_bottom: f64, horizontal_padding: f64, vertical_padding: f64, ) -> Option<Interval>

The widest horizontal intersection of a circle with the entire line band. A tangent band has no occupied area and yields None.

Source

pub fn ellipse_interval_for_band( cx: f64, cy: f64, radius_x: f64, radius_y: f64, band_top: f64, band_bottom: f64, horizontal_padding: f64, vertical_padding: f64, ) -> Option<Interval>

Source

pub fn get_rect_intervals_for_band( rects: &[RectObstacle], band_top: f64, band_bottom: f64, horizontal_padding: f64, vertical_padding: f64, ) -> Vec<Interval>

Source

pub fn pick_slot( slots: &[Interval], prefer_right_on_tie: bool, ) -> Option<Interval>

Pick the widest usable slot and resolve equal widths by horizontal order. Empty inputs return None instead of indexing an absent first interval.
