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

[Android.Runtime.Register("getPosTan", "(F[F[F)Z", "GetGetPosTan_FarrayFarrayFHandler")]
public virtual bool GetPosTan (float distance, float[]? pos, float[]? tan);

[<Android.Runtime.Register("getPosTan", "(F[F[F)Z", "GetGetPosTan_FarrayFarrayFHandler")>]
abstract member GetPosTan : single * single[] * single[] -> bool
override this.GetPosTan : single * single[] * single[] -> bool

Parameters

distance: Single

The distance along the current contour to sample

pos: Single[]

If not null, returns the sampled position (x==[0], y==[1])

tan: Single[]

If not null, returns the sampled tangent (x==[0], y==[1])

Returns

Boolean

false if there was no path associated with this measure object

Attributes: RegisterAttribute

Remarks

Pins distance to 0 <= distance <= getLength(), and then computes the corresponding position and tangent. Returns false if there is no path, or a zero-length path was specified, in which case position and tangent are unchanged.
