ContourEdge

data class ContourEdge(val contour: ShapeContour, val segmentIndex: Int, val adjustments: List<SegmentOperation> = emptyList())(source)

Helper for querying and adjusting ShapeContour.

An edge embodies exactly the same thing as a Segment2D
All edge operations are immutable and will create a new ContourEdge pointing to a copied and updated ShapeContour

Since

0.4.4

Parameters

contour

the contour to be adjusted

segmentIndex

the index the contour's segment to be adjusted

adjustments

a list of SegmentOperation that have been applied to reach to contour, this is used to inform ShapeContour of changes in the contour topology.

Functions

control0MovedBy

fun control0MovedBy(translation: Vector2): ContourEdge

Moves the first control point of a contour edge by a specified translation vector.

control1MovedBy

fun control1MovedBy(translation: Vector2): ContourEdge

Moves the second control point (Control1) of a contour edge by a specified translation vector.

endMovedBy

fun endMovedBy(translation: Vector2, updateTangents: Boolean = true): ContourEdge

Moves the end point of the contour edge by the specified translation vector.

maskOf

fun maskOf(vararg control: ContourEdge.ControlMask): Int

movedBy

fun movedBy(translation: Vector2, updateTangents: Boolean = true): ContourEdge

Creates a new contour edge by applying a translation to the current edge.

replacedWith

fun replacedWith(t: Double): ContourEdge

Replace this edge with a point at t

fun replacedWith(openContour: ShapeContour): ContourEdge

Replaces the current edge with the segments of an open shape contour.

rotatedBy

fun rotatedBy(rotationInDegrees: Double, anchorT: Double, updateTangents: Boolean = true): ContourEdge

scaledBy

fun scaledBy(scaleFactor: Double, anchorT: Double, updateTangents: Boolean = true): ContourEdge

fun scaledBy(scaleFactor: Double, anchor: Vector2, updateTangents: Boolean = true): ContourEdge

splitAt

fun splitAt(t: Double): ContourEdge

Split the edge at t

splitIn

fun splitIn(parts: Int): ContourEdge

startMovedBy

fun startMovedBy(translation: Vector2, updateTangents: Boolean = true): ContourEdge
