◆ Image

__int3264 Image

Pipelines an image to the Common Vision DigIO Control.

Attention
The DigIO Control requires the image object to support the BasicDigIO interface. If this interface is not supported all the control properties, methods and events are disabled. Verify with the IsBasicDigIO property if the image object supports the BasicDigIO interface.
Parameters
[in,out]ImageHandle of the image object.
Returns
Image object handle.
Examples:
Delphi - Delphi Digital I/O Example
Visual Basic - VB Digital I/O Example
Visual C++ - VC Digital I/O Example

◆ IsBasicDigIO

boolean IsBasicDigIO
