Encoding Mechanism Type Constants

Encoding Mechanisms indicates the encoding filter used.

• EncodeType_Base64 (3) – Base 64 encoding.  Converts 3 bytes of binary data to 4 bytes of ASCII text.
• EncodeType_Ascii_Baudot (4) – ASCII Baudot.  Converts 7-bit ASCII characters to 5-bit Baudot characters.
• EncodeType_EDA_Filter (5) – EDA filter.  Converts 2 bytes of binary data to 3 bytes of ASCII characters.  Primarily used by UN/EDIFACT to convert documents to use the character set repertoire A or B which is constrained to using only 44 characters.
• EncodeType_EDC_Filter (6) – EDC filter.  Converts 18 bytes to 19 filtered bytes.  Primarily used by UN/EDIFACT for character set repertoires C to F.
• EncodeType_Hexadecimal (7) – Hexadecimal filter.  Converts each decimal value of a data byte to its 2 hexadecimal character representation of 0 to 9 and A to F.  This method expands the stream to 100%.
• EncodeType_QuotedPrintable (8) – Quoted Printable.  Converts a binary stream into a stream of ASCII printable characters.
• EncodeType_Radix64 (9) – Radix-64.  Encodes by using Base 64 encoding (converts 3 bytes of binary data to 4 bytes of ASCII text) and then generates a checksum.
• EncodeType_UUEncode (10) – UUEncode.  Similar to Base 64 encoding, converts 3 bytes of binary data to 4 bytes of ASCII text.
