Zoomļƒ

Virtual zoom is described with a single dimensionless value of type integer. Similar to the interfaces described above, virtual zoom can be managed with these methods:

  • setZoom(int zoom)

  • getZoom()

  • getMinZoom()

  • getMaxZoom()

The Logitech C920 allows zoom values ranging from 100 to 500, although values higher than 250-280 have no further effect on the preview image (influenced by Vuforia).

These zoom methods are called on a PtzControl object, as described above for exposure.
