Status: | Open | Resolved: | |
Product: | iOS + SDK (Core Graphics) | Product Version: | iOS 11.4 / 15F79 |
Classification: | Serious bug | Reproducible: | always |
Summary: For cases like this: let path = UIBezierPath() path.move(to: CGPoint(x: 50, y: 50)) let to = CGPoint(x: 50, y: 10) let p1 = CGPoint(x: 20, y: 20) let p2 = CGPoint(x: 40, y: 20) path.addCurve(to: to, controlPoint1: p1, controlPoint2: p2) let cgPath = path.cgPath print(cgPath.boundingBoxOfPath) // valid: (34.16, 10.0, 15.84, 40.0) ctx.addPath(cgPath) print(ctx.boundingBoxOfPath) // invalid: (20.0, 10.0, 30.0, 40.0) boundingBoxOfPath return wrong results Steps to Reproduce: just paste this code into the project with core graphics included. Expected Results: The path has bounds - 34.16, 10.0, 15.84, 40.0 Actual Results: The path has bounds - 20.0, 10.0, 30.0, 40.0
