Methods

Generate()

Generates an observable sequence that reads a block of pixels from the framebuffer and returns the data as an image object.

public override IObservable<IplImage> Generate()

Returns

IObservable<IplImage>

An observable sequence with a single IplImage object storing the pixels read from the framebuffer at the next state update.

Generate<TSource>(IObservable<TSource>)

Reads a block of pixels from the framebuffer whenever an observable sequence emits a notification.

public IObservable<IplImage> Generate<TSource>(IObservable<TSource> source)

Parameters

source IObservable<TSource>

The sequence containing the notifications used to read a block of pixels from the framebuffer.

Returns

IObservable<IplImage>

A sequence of IplImage objects storing the pixels read from the framebuffer whenever the source sequence emits a notification.

Type Parameters

TSource

The type of the elements in the source sequence.
