Functions

checkChecksum

open override fun checkChecksum(s: String): Boolean

decode

open override fun decode(image: BinaryBitmap): Result

Locates and decodes a barcode in some format within an image.

open override fun decode(image: BinaryBitmap, hints: Map<DecodeHintType, *>?): Result

Locates and decodes a barcode in some format within an image. This method also accepts hints, each possibly associated to some data, which may help the implementation decode.

decodeEnd

open override fun decodeEnd(row: BitArray, endStart: Int): IntArray

decodeRow

open override fun decodeRow(rowNumber: Int, row: BitArray, hints: Map<DecodeHintType, *>?): Result

Attempts to decode a one-dimensional barcode format given a single row of an image.

open fun decodeRow(rowNumber: Int, row: BitArray, startGuardRange: IntArray, hints: Map<DecodeHintType, *>?): Result

Like decodeRow, 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.

getBarcodeFormat

open override fun getBarcodeFormat(): BarcodeFormat

Get the format of this decoder.

reset

open override fun reset()

Resets any internal state the implementation has after a decode, to prepare it for reuse.
