Parameters

Name Type Range Default Description
ioStateFil.ReadDataMatrixCodes_State
inImageFil.ImageInput image.
inRoiFtl.Optional<Fil.Rectangle2D>Region of interest. Default value: ftl::NIL.
inRoiAlignmentFtl.Optional<Fil.CoordinateSystem2D>Coordinate system for the region of interest. Default value: ftl::NIL.
inCodeParamsFil.DatacodeParamsSpecification of codes that can be detected.
inDetectionParamsFil.DatacodeDetectionParamsParameters of the code detection algorithm.
inComputeScoresboolEnables computing of confidence scores (much slower!).
inMaxCodeCountint<0, INF>2Maximum number of codes in one image. Default value: 2.
inAllowMultipleScalesboolFalseSpecifies whether to continue search for codes at a higher resolution even when some codes have already been found at a lower resolution. Default value: False.
inTypeSelectionFil.DataCodeTypeSelectionSpecifies which code types the filter should try to read.
outDataCodesSystem.Collections.Generic.List<Fil.DataCode>List of codes that have been correctly detected and decoded.
outCandidatesSystem.Collections.Generic.List<Fil.Path>Diagnostic information about detection results.
outAlignedRoiFtl.Optional<Fil.Rectangle2D>Input ROI after transformation (in the image coordinates).
