Dispose ( ) : void	Closes and cleans the video previewing.
GetFrame ( ) : Bitmap	Gets the current frame from the buffer.
PrepareCapture ( ) : void	Prepares the capture of frames.

StopPreview ( ) : void	Stops the video previewing.

Méthodes protégées

Méthode	Description
CreateGraph ( ) : void	Create a new filter graph and add filters (devices, compressors, misc), but leave the filters unconnected. Call RenderGraph() to connect the filters.
DerenderGraph ( ) : void	Disconnect and remove all filters except the device and compressor filters. This is the opposite of renderGraph(). Soem properties such as FrameRate can only be set when the device output pins are not connected.
DestroyGraph ( ) : void	Completely tear down a filter graph and release all associated resources.
OnPreviewWindowResize ( object sender, EventArgs e ) : void	Resize the preview when the PreviewWindow is resized
RemoveDownstream ( CoreStreaming filter, bool removeFirstFilter ) : void	Removes all filters downstream from a filter from the graph. This is called only by DerenderGraph() to remove everything from the graph except the devices and compressors. The parameter "removeFirstFilter" is used to keep a compressor (that should be immediately downstream of the device) if one is begin used.
RenderGraph ( ) : void	Connects the filters of a previously created graph (created by CreateGraph()). Once rendered the graph is ready to be used. This method may also destroy streams if we have streams we no longer want.
StartPreviewIfNeeded ( ) : void	Setup and start the preview window if the user has requested it (by setting PreviewWindow).
