Camera use zoom without dialog

Post by GHWels » Sun Mar 19, 2017 8:40 pm

Hey Alex!

Is it possible without the camera-dialog to set

1.) autofocus?
2.) zoom?

I testet it with your sample-Software 'WebcamBarcodeReaderDemo'

Hello Gunther,
Is it possible without the camera-dialog to set...
Do you want to control camera proprties using VintaSoft Twain .NET SDK? If yes, you need try to control the camera properties using the custom device capabilities, here is the article that describes how to work with the custom device capabilities: https://www.vintasoft.com/forums/viewto ... =25&t=2366


VintaSoft Imaging .NET SDK also allows to work with DirectShow cameras.

Please see here the example that shows how to get and set the camera control properties of DirectShow camera:
