EncodingMode Enumeration

Specifies the encoding mode for compacting the data for the QR Code symbol. The modes are based on the character values and assignments associated with the default ECI (ECI 000003 representing the ISO/IEC 8859-1 character set).

Syntax

C#

public enum EncodingMode : System.Enum 

Members

Member	Description
Alphanumeric	Alphanumeric mode encodes data from a set of 45 characters (digits 0-9, upper case letters A-Z, nine other characters: space, $ % * + _ . / : ). Normally two input characters are represented by 11 bits.
Byte	In Byte mode the data is encoded at 8 bits per character. The character set of the Byte encoding mode is byte data (by default it is ISO/IEC 8859-1 character set).
Kanji	The Kanji mode efficiently encodes Kanji characters in accordance with the Shift JIS system based on JIS X 0208. Each two-byte character value is compacted to a 13-bit binary codeword.
Numeric	Numeric mode encodes data from decimal digit set (0-9). Normally 3 data characters are represented by 10 bits.
Undefined	When Undefined encoding mode is set, the QR code barcode internally switches between modes as necessary in order to achieve the most efficient conversion of data into a binary string.
