- """
- Code 128 is a very compact symbology that can encode the entire
- 128 character ASCII set, plus 4 special control codes,
- (FNC1-FNC4, expressed in the input string as \xf1 to \xf4).
- Code 128 can also encode digits at double density (2 per byte)
- and has a mandatory checksum. Code 128 is well supported and
- commonly used -- for example, by UPS for tracking labels.
-
- Because of these qualities, Code 128 is probably the best choice
- for a linear symbology today (assuming you have a choice).
-
- Options that may be passed to constructor:
-
- value (int, or numeric string. required.):
- The value to encode.
-
- xdim (float, default .0075):
- X-Dimension, or width of the smallest element
- Minumum is .0075 inch (7.5 mils).
-
- height (float, see default below):
- Height of the symbol. Default is the height of the two
- bearer bars (if they exist) plus the greater of .25 inch
- or .15 times the symbol's length.
-
- quiet (bool, default 1):
- Wether to include quiet zones in the symbol.
-
- lquiet (float, see default below):
- Quiet zone size to left of code, if quiet is true.
- Default is the greater of .25 inch, or 10 xdim
-
- rquiet (float, defaults as above):
- Quiet zone size to right left of code, if quiet is true.
