Flags
The flag parameter in barcode() calls is made of the following bits:
B0 – the line separator.
B1 – the Aztec Flag.
B2 – the Aztec Menu flag
B3 – the Reverse video flag
The bit values are defined in azlib.h
#define DL_LINEFLAG 1 - ; if this bit is 0 then the line separator is a carriage return character; if this bit it 1 then the line separator is a carriage return and a line feed character.
#define DL_AZFLAG 2 - specifies an Aztec Flag. When not set input is in bytes. When set input uses <Esc>n for FLG(n).
#define DL_AZMENU 4 – specifies an Aztec Menu Symbol when set.
#define DL_AZRVIDEO 8 – specifies that the Aztec symbol may be produced in Reversed Video (i.e. white on black)
