Function Documentation

XN_C_API XnStatus XN_C_DECL xnCreateIRGenerator	(	XnContext *	pContext,
		XnNodeHandle *	phIRGenerator,
		XnNodeQuery *	pQuery,
		XnEnumerationErrors *	pErrors
	)

Creates an IR generator.

Parameters:

pContext	[in] The context in which to create the IR generator.
phIRGenerator	[out] A handle to the created IR generator.
pQuery	[in] Optional. Can be used to select which IR generator to create. If not specified, this function may create any IR generator that is available.
pErrors	[in] Optional. If provided, will be filled with information about IR generators that could not be created.

XN_C_API XnIRPixel* XN_C_DECL xnGetIRMap

(

XnNodeHandle

hInstance

)

Gets the current IR-map. This map is updated after a call to xnWaitAndUpdateData().

Parameters:

hInstance

[in] A handle to the instance.

Returns:

NULL if this production node is not an IR generator.

XN_C_API void XN_C_DECL xnGetIRMetaData	(	XnNodeHandle	hInstance,
		XnIRMetaData *	pMetaData
	)

Gets the current IR-map meta data.

Parameters:

hInstance	[in] A handle to the instance.
pMetaData	[in] The struct to be filled.
