pub fn text_split_points(line_count: usize, line_height: f64) -> Vec<f64>Expand description
Compute valid split positions (y-offsets) for multiline text.
XFA Spec 3.3 §8.7 (p291): text may be split between lines only. Returns the y-position of each line boundary (after line 1, after line 2, …). A text with N lines has N−1 split points.
