TUPCEANReader.DoDecodeRow Method

Definition

Unit:: ZXing.OneD.UPCEANReader

Package:: QRCodeReader_FMX

Like decodeRow(int, BitArray, java.util.Map), but allows caller to inform method about where the UPC/EAN start pattern is found. This allows this to be computed once and reused across many implementations.

Delphi

function DoDecodeRow(const rowNumber: Integer; const row: IBitArray; const startGuardRange: TArray<Integer>; const hints: TDictionary<TDecodeHintType, TObject>): TReadResult

Parameters

rowNumber: Integer

row index into the image

row: IBitArray

encoding of the row of the barcode image

startGuardRange: TArray<Integer>

start/end column where the opening start pattern was found

hints: TDictionary<TDecodeHintType, TObject>

optional hints that influence decoding

Returns
