IID_IuEyeFocus
This interface provides special functions for controlling the focus of some uEye cameras that are not covered by the DirectShow standard.
For the USB uEye XS, you can also use the focus measure window for defining which area should be focused. The position of the measure window can be freely defined. The measure window of the UI-1007XS has a fixed size, which can be queried via Focus_GetAutoFocusZoneSizeMin and Focus_GetAutoFocusZoneSizeMax.
To use the interface, you must integrate the uEyeCaptureInterface.h header file into your project.
