have no other significance.

A 3-digit convolutional error correction level.
If any number other than one of these options is entered then
the nearest lesser value from the valid entries is used.
Example: Selecting an ECC value of 099 will cause the actual
0 - 6 1 digit format identification:
0 - Automatically choose the encodation scheme based on
the characters to be encoded.
1 - Numeric data.
2 - Upper-case alphabetic.
3 - Upper-case alphanumeric and punctuation characters
(period, comma, hyphen, and slash).
4 - Upper-case alphanumeric.
5 - ASCII, the full 128 ASCII character set.
6 - Any 8-bit byte.
If a format identifier is selected which will not encode the
input character stream then the bar code symbol will not be
printed.
It is recommended to use the auto-encodation format
identification since it will select the best possible encodation
scheme for the input stream.
A 3 digit odd number (or 000) of rows requested. 000 causes
rows to be automatically determined. If the rows and columns
do not match, the symbol will be sized to a square using the
greater of the two values.
A 3 digit odd number (or 000) of columns requested. 000
causes columns to be automatically determined. If the rows
and columns do not match, the symbol will be sized to a
square using the greater of the two values.
Data to be encoded.
