ImmutableVec
kotlin.Any
   ↳ androidx.ink.geometry.Vec
     ↳ androidx.ink.geometry.ImmutableVec

An immutable two-dimensional vector, i.e. an (x, y) coordinate pair. It can be used to represent either:

  1. A two-dimensional offset, i.e. the difference between two points

  2. A point in space, i.e. treating the vector as an offset from the origin

This object is immutable, so it is inherently thread-safe. See MutableVec for a mutable alternative.

Boolean
isAlmostEqual(other: Vec, tolerance: @FloatRange(from = 0.0) Float)

Compares this Vec with other, and returns true if the difference between x and other.x is less than tolerance, and likewise for y.

Boolean
isParallelTo(
    other: Vec,
    toleranceDegrees: @AngleDegreesFloat @FloatRange(from = 0.0) Float

Boolean
isPerpendicularTo(
    other: Vec,
    toleranceDegrees: @AngleDegreesFloat @FloatRange(from = 0.0) Float
