Methods

Process()

Generates an observable sequence that contains an affine transformation matrix specified by a translation, rotation and scale.

public IObservable<Mat> Process()

Returns

IObservable<Mat>

A sequence containing a single instance of the Mat class representing an affine transformation matrix.

Process<TSource>(IObservable<TSource>)

Generates an observable sequence of affine transformation matrices using the specified translation, rotation and scale, and where each matrix is emitted only when an observable sequence emits a notification.

public override IObservable<Mat> Process<TSource>(IObservable<TSource> source)

Parameters

source IObservable<TSource>

The sequence containing the notifications used for emitting new affine transformation matrices.

Returns

IObservable<Mat>

A sequence of Mat objects where each element represents an affine transformation matrix.

Type Parameters

TSource

The type of the elements in the source sequence.
