Hi,
Is this required Twain driver for Webcam? Webcam is available but the webcam source is not loading in GdPictureImaging.TwainSelectSource(Handle). Please kindly do the needful. Thanks.
The scanner twain source is loading perfectly in GdPictureImaging.TwainSelectSource(Handle) but not listing Webcam.

Hello,
GdPicture viewer does not support video and audio.
So the TWAIN connection is not handled by our solution regarding this kind of device.
Best regards,
Fabio

Thanks for your reply.
Can't we access webcam through GdPicture for just capturing the image? We just need to capture patient image only through Webcam using our application.

Hello,
To do that you need to have a Twain driver for your digital camera.
The twain driver must be provided by the camera manufacturer.
By the way, all cameras do not provide this feature.
The most efficient way to obtain real-time video with low CPU usage without using the build-in camera preview interface is to use the Direct Show API which is for me the best way to manage real-time video from windows applications.
If you are programming in .NET you can check this project:

Hope it helps!
With best,
