Some depth sensors (for example XtionPRO) do not have image generator. In order to check it you can get ``CV_CAP_OPENNI_PROP_IMAGE_GENERATOR_PRESENT`` property.
::
bool isImageGeneratorPresent = capture.get( CV_CAP_OPENNI_PROP_IMAGE_GENERATOR_PRESENT ) != 0; // or == 1
bool isImageGeneratorPresent = capture.get( CV_CAP_PROP_OPENNI_IMAGE_GENERATOR_PRESENT ) != 0; // or == 1
Flags specifing the needed generator type must be used in combination with particular generator property. The following properties of cameras available through OpenNI interfaces are supported:
