Parameters

Name Type Range Default Description
inCharactersSystem.Collections.Generic.List<Fil.OcrResult>Output of DL_ReadCharacters.
inMaxGapfloat<0.0f, 10.0f>0.25fMaximum horizontal gap between joint characters' boxes, denoted as fraction of 'A' char height. Default value: 0.25f.
inMaxShiftfloat<0.0f, 1.0f>0.25fMaximum vertical misalignment between joint character's boxes, denoted as fraction of 'A' char height. Default value: 0.25f.
inMarginfloat<0.0f, 10.0f>Additional margin added to result, denoted as fraction of 'A' char height.
inMinLengthint<1, 200>1Minimal number of chars to create line. Default value: 1.
inFlattenboolFalseIf True, it concatenates the words on the line into a single result string, otherwise each word is a separate result string. Default value: False.
inPatternstringPattern used in Grammar rules filtering.
inCandidatesFtl.Optional<System.Collections.Generic.List<System.Collections.Generic.List<Fil.OcrCandidate>>>Candidates - optional output of DL_ReadCharacters, Required when using grammar rules (when inPattern is not empty). Default value: ftl::NIL.
inMinScorefloat<0.0f, 1.0f>0.2fMinimum score for filtering the line of text. Default value: 0.2f.
outLinesSystem.Collections.Generic.List<Fil.Rectangle2D>Minimal Box which cover all selected character boxes.
outStringsSystem.Collections.Generic.List<string>Text of merged characters.
outMappingSystem.Collections.Generic.List<Ftl.Conditional<int>>Mapping between input characters and output lines, outMapping[i] stores the index line to which inCharacters[i] belongs. If outMapping[i] is NIL it means that inCharacters[i] has not been added to any line.
outScoresSystem.Collections.Generic.List<float>Calculated the score for the line.
