One of:
DM_AUTO
- the best encodation will be used
DM_ASCII
- ASCII encodation
DM_C40
- C40 encodation
DM_TEXT
- TEXT encodation
DM_B256
- binary encodation
DM_X21
- X21 encodation
DM_EDIFACT
- EDIFACT encodation
DM_RAW
- no encodation. The bytes provided are already encoded and will be added directly to the barcode, using padding if needed. It assumes that the encodation state is left at ASCII after the last byte.
One of:
DM_EXTENSION
- allows extensions to be embedded at the start of the text:
exxxxxx - ECI number xxxxxx
m5 - macro 5
m6 - macro 6
f - FNC1
saabbccccc - Structured Append, aa symbol position (1-16), bb total number of symbols (2-16), ccccc file identification (0-64515)
p - Reader programming
. - extension terminator
Example for a structured append, symbol 2 of 6, with FNC1 and ECI 000005. The actual text is "Hello".
s020600075fe000005.Hello
One of:
DM_TEST
- doesn't generate the image but returns all the other information.
