PathMeasure

fun getPosition(distance: Float): Offset

Pins distance to 0 <= distance <= getLength(), and then computes the corresponding position

fun getSegment(
    startDistance: Float,
    stopDistance: Float,
    destination: Path,
    startWithMoveTo: Boolean = true
): Boolean

Given a start and stop distance, return in dst the intervening segment(s). If the segment is zero-length, return false, else return true. startD and stopD are pinned to legal values (0..getLength()). If startD >= stopD then return false (and leave dst untouched). Begin the segment with a moveTo if startWithMoveTo is true.

fun getTangent(distance: Float): Offset

Pins distance to 0 <= distance <= getLength(), and then computes the corresponding tangent

fun setPath(path: Path?, forceClosed: Boolean): Unit

Assign a new path, or null to have none.

val length: Float

The total length of the current contour, or 0 if no path is associated with this measure object.
