  • Reference

Definition

Namespace:
Android.Graphics
Assembly:
Mono.Android.dll

Overloads

MapVectors(Single[])

Apply this matrix to the array of 2D vectors, and write the transformed vectors back into the array.
MapVectors(Single[], Single[])

Apply this matrix to the array of 2D vectors specified by src, and write the transformed vectors into the array of vectors specified by dst.
MapVectors(Single[], Int32, Single[], Int32, Int32)

Apply this matrix to the array of 2D vectors specified by src, and write the transformed vectors into the array of vectors specified by dst.

MapVectors(Single[])

Apply this matrix to the array of 2D vectors, and write the transformed vectors back into the array.

[Android.Runtime.Register("mapVectors", "([F)V", "GetMapVectors_arrayFHandler")]
public virtual void MapVectors (float[]? vecs);
[<Android.Runtime.Register("mapVectors", "([F)V", "GetMapVectors_arrayFHandler")>]
abstract member MapVectors : single[] -> unit
override this.MapVectors : single[] -> unit

Parameters

vecs
Single[]

The array [x0, y0, x1, y1, ...] of vectors to transform.

Attributes
RegisterAttribute

Remarks

Apply this matrix to the array of 2D vectors, and write the transformed vectors back into the array. Note: this method does not apply the translation associated with the matrix. Use Matrix#mapPoints(float[]) if you want the translation to be applied.

Applies to

MapVectors(Single[], Single[])

Apply this matrix to the array of 2D vectors specified by src, and write the transformed vectors into the array of vectors specified by dst.

[Android.Runtime.Register("mapVectors", "([F[F)V", "GetMapVectors_arrayFarrayFHandler")]
public virtual void MapVectors (float[]? dst, float[]? src);
[<Android.Runtime.Register("mapVectors", "([F[F)V", "GetMapVectors_arrayFarrayFHandler")>]
abstract member MapVectors : single[] * single[] -> unit
override this.MapVectors : single[] * single[] -> unit

Parameters

dst
Single[]

The array of dst vectors (x,y pairs)

src
Single[]

The array of src vectors (x,y pairs)

Attributes
RegisterAttribute

Remarks

Apply this matrix to the array of 2D vectors specified by src, and write the transformed vectors into the array of vectors specified by dst. The two arrays represent their "vectors" as pairs of floats [x, y]. Note: this method does not apply the translation associated with the matrix. Use Matrix#mapPoints(float[], float[]) if you want the translation to be applied.

Applies to

MapVectors(Single[], Int32, Single[], Int32, Int32)

Apply this matrix to the array of 2D vectors specified by src, and write the transformed vectors into the array of vectors specified by dst.

[Android.Runtime.Register("mapVectors", "([FI[FII)V", "GetMapVectors_arrayFIarrayFIIHandler")]
public virtual void MapVectors (float[]? dst, int dstIndex, float[]? src, int srcIndex, int vectorCount);
[<Android.Runtime.Register("mapVectors", "([FI[FII)V", "GetMapVectors_arrayFIarrayFIIHandler")>]
abstract member MapVectors : single[] * int * single[] * int * int -> unit
override this.MapVectors : single[] * int * single[] * int * int -> unit

Parameters

dst
Single[]

The array of dst vectors (x,y pairs)

dstIndex
Int32

The index of the first [x,y] pair of dst floats

src
Single[]

The array of src vectors (x,y pairs)

srcIndex
Int32

The index of the first [x,y] pair of src floats

vectorCount
Int32

The number of vectors (x,y pairs) to transform

Attributes
RegisterAttribute

Remarks

Apply this matrix to the array of 2D vectors specified by src, and write the transformed vectors into the array of vectors specified by dst. The two arrays represent their "vectors" as pairs of floats [x, y]. Note: this method does not apply the translation associated with the matrix. Use Matrix#mapPoints(float[], int, float[], int, int) if you want the translation to be applied.
