pathToPen :: Floating a => ClosedPath a -> Pen a Source #

Create a pen from a path. For predictable results the path should be convex.

penStrokeOpen :: Int -> Double -> Bool -> Pen Double -> OpenPath Double -> [ClosedPath Double] Source #

penStrokeClosed :: Int -> Double -> Bool -> Pen Double -> ClosedPath Double -> [ClosedPath Double] Source #

:: CubicBezier Double | The curve |

-> Double | Offset distance. |

-> Maybe Int | maximum subcurves |

-> Double | Tolerance. |

-> Bool | Calculate the curve faster but with more subcurves |

-> [CubicBezier Double] | The offset curve |

Calculate an offset path from the bezier curve to within tolerance. If the distance is positive offset to the left, otherwise to the right. A smaller tolerance may require more bezier curves in the path to approximate the offset curve
