	atl::Optional<const avl::Rectangle2D&> inRoi,
	atl::Optional<const avl::CoordinateSystem2D&> inRoiAlignment,
	const avl::DatacodeParams& inCodeParams,
	const avl::DatacodeDetectionParams& inDetectionParams,
	bool inComputeScores,
	int inMaxCodeCount,
	bool inAllowMultipleScales,
	const avl::DataCodeTypeSelection& inTypeSelection,

)

Parameters

Name	Type	Range	Default	Description
ioState	ReadDataCodes_State&			Object used to maintain state of the function.
inImage	const Image&			Input image
inRoi	Optional<const Rectangle2D&>		NIL	Region of interest
inRoiAlignment	Optional<const CoordinateSystem2D&>		NIL	Coordinate system for the region of interest
inCodeParams	const DatacodeParams&			Specification of codes that can be detected
inDetectionParams	const DatacodeDetectionParams&			Parameters of the code detection algorithm
inComputeScores	bool			Enables computing of confidence scores (slower)
inMaxCodeCount	int	0 -	2	Maximum number of codes in one image
inAllowMultipleScales	bool		False	Specifies whether to continue search for codes at a higher resolution even when some codes have already been found at a lower resolution
inTypeSelection	const DataCodeTypeSelection&			Specifies which code types the filter should try to read
outDataCodes	Array<DataCode>&			List of codes that have been correctly detected and decoded
outCandidates	Array<Path>&			Diagnostic information about detection results
outAlignedRoi	Optional<Rectangle2D&>		NIL	Input ROI after transformation (in the image coordinates)

Optional Outputs

The computation of following outputs can be switched off by passing value atl::NIL to these parameters: outAlignedRoi.
