Public Methods

Method	Description
Code39Reader ( ) : System	Creates a reader that assumes all encoded data is data, and does not treat the final character as a check digit. It will not decoded "extended Code 39" sequences.
Code39Reader ( bool usingCheckDigit ) : System	Creates a reader that can be configured to check the last character as a check digit. It will not decoded "extended Code 39" sequences.
Code39Reader ( bool usingCheckDigit, bool extendedMode ) : System	Creates a reader that can be configured to check the last character as a check digit, or optionally attempt to decode "extended Code 39" sequences that are used to encode the full ASCII character set.
decodeRow ( int rowNumber, BitArray row, object>.IDictionary hints ) : System.Result	Attempts to decode a one-dimensional barcode format given a single row of an image.

Method Details

Code39Reader() public method

Creates a reader that assumes all encoded data is data, and does not treat the final character as a check digit. It will not decoded "extended Code 39" sequences.

public Code39Reader ( ) : System
return	System

Code39Reader() public method

Creates a reader that can be configured to check the last character as a check digit. It will not decoded "extended Code 39" sequences.

public Code39Reader ( bool usingCheckDigit ) : System
usingCheckDigit	bool	if true, treat the last data character as a check digit, not /// data, and verify that the checksum passes.
return	System

Code39Reader() public method

Creates a reader that can be configured to check the last character as a check digit, or optionally attempt to decode "extended Code 39" sequences that are used to encode the full ASCII character set.

public Code39Reader ( bool usingCheckDigit, bool extendedMode ) : System
usingCheckDigit	bool	if true, treat the last data character as a check digit, not /// data, and verify that the checksum passes.
extendedMode	bool	if true, will attempt to decode extended Code 39 sequences in the text.
return	System

decodeRow() public method

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

public decodeRow ( int rowNumber, BitArray row, object>.IDictionary hints ) : System.Result
rowNumber	int	row number from top of the row
row	ZXing.Common.BitArray	the black/white pixel data of the row
hints	object>.IDictionary	decode hints
return	System.Result
