Anti Flicker Capability


XN_C_API XnStatus XN_C_DECL xnSetPowerLineFrequency (XnNodeHandle hGenerator, XnPowerLineFrequency nFrequency)
XN_C_API XnPowerLineFrequency
xnGetPowerLineFrequency (XnNodeHandle hGenerator)
XN_C_API XnStatus XN_C_DECL xnRegisterToPowerLineFrequencyChange (XnNodeHandle hGenerator, XnStateChangedHandler handler, void *pCookie, XnCallbackHandle *phCallback)
XN_C_API void XN_C_DECL xnUnregisterFromPowerLineFrequencyChange (XnNodeHandle hGenerator, XnCallbackHandle hCallback)

Detailed Description

The Anti Flicker capability (XN_CAPABILITY_ANTI_FLICKER) allows a Map Generator to time its frames in such a way that no flickering will take place due to electric light frequencies.

Function Documentation

XN_C_API XnPowerLineFrequency XN_C_DECL xnGetPowerLineFrequency ( XnNodeHandle  hGenerator)

Gets the power line frequency.

hGenerator[in] A handle to the instance.
(XnUInt32)-1 if node does not support this capability
XN_C_API XnStatus XN_C_DECL xnRegisterToPowerLineFrequencyChange ( XnNodeHandle  hGenerator,
XnStateChangedHandler  handler,
void *  pCookie,
XnCallbackHandle phCallback 

Registers a callback function to power line frequency changes.

hGenerator[in] A handle to the instance.
handler[in] A pointer to a function that will be called when power line frequency changes.
pCookie[in] A user cookie that will be passed to the callback function.
phCallback[out] Optional. Will be filled with a handle to be passed to xnUnregisterFromPowerLineFrequencyChange().
XN_C_API XnStatus XN_C_DECL xnSetPowerLineFrequency ( XnNodeHandle  hGenerator,
XnPowerLineFrequency  nFrequency 

Sets the power line frequency: 50 Hz, 60 Hz, or 0 to turn off anti-flicker.

hGenerator[in] A handle to the instance.
nFrequency[in] The frequency to be used.
XN_C_API void XN_C_DECL xnUnregisterFromPowerLineFrequencyChange ( XnNodeHandle  hGenerator,
XnCallbackHandle  hCallback 

Unregisters a callback function which was registered using xnRegisterToPowerLineFrequencyChange().

hGenerator[in] A handle to the instance.
hCallback[in] The handle to the callback returned from xnRegisterToPowerLineFrequencyChange().
