virtual Image^ GetStillImage(
int timeOut
)
timeOut
Value containing the maximum time to wait for the image, in milliseconds.
Captured video image as a System.Drawing.Image
Gets a System.Drawing.Image object during a CaptureMode.Still capture. If TimeOut is -1, the method's time-out interval never elapses. If the method fails, an error is raised. For more information, refer to the Error Codes.
Note: The frame data is retrieved from the underlying graph after the processing filters. If the capture needs to occur before the processing is completed use the LeadVideoCallBackFilter and place it first in the collection of processing filters.
