Panic : stroke_path hair line (specific path values) #47
Description
With tiny-skia = "0.6.3"
This code crash, i think it is related to "hair line" because the same path with 1.0 for width works :
use tiny_skia::{Pixmap, PathBuilder, Transform, Stroke, Paint}; fn main() { let mut pixmap = Pixmap::new(512, 512).unwrap(); let mut builder = PathBuilder::default(); builder.move_to(338.80466, 545.2891); builder.line_to(369.26462, 577.8069); builder.line_to(488.0846, 471.04388); let path = builder.finish().unwrap(); let stroke = Stroke { width: 0.0, // with 1.0 : it runs fine ..Default::default() }; pixmap.stroke_path(&path, &Paint::default(), &stroke, Transform::identity(), None); }Stacktrace :
