ratio
NOTE: VGL automatically checks ratio data for validity only within the
allowable hexadecimal range. VGL does not verify that ratio data
creates acceptable wide/narrow element relationships for bar code
readability. For example, VGL accepts wide/narrow ratio values of 2
and 5, respectively; however a narrow element larger than the wide
element produces an unreadable bar code. When designing unique
ratio data, carefully plot wide and narrow ratios to conform to
readable bar codes.

German Interleaved 2/5 Examples
The following command generates the horizontal default ratio German
Interleaved 2/5 bar code shown below. In the command sequence, graphics
mode data is italicized and bar code data is boldface. See Chapter 2 for a
detailed description of alphanumeric commands.
^PY^-^M10,10,000^KF^BTV01853624568^G^KF^-^PN^-
Optional parameter (used in conjunction with 9 or :
above) representing the ratios for variable ratio bar
codes. Default ratios are overridden by the variable
ratio feature. The ratio data must be hexadecimal
numbers from 0 through 9 or A through F. VGL
automatically checks the input for validity. If an
invalid character is found in the ratio, an error
message is generated.
German Interleaved 2/5 bar codes use four-digit
ratios. The ratios are interpreted from left to right,
measuring the size of each bar or space, in dot
width, in the following pattern: narrow bar : narrow
space : wide bar : wide space . For example, enter
2266 in the ratio parameter for:
2 dot-wide narrow bar
2 dot-wide narrow space
6 dot-wide wide bar
6 dot-wide wide space
The bar code data. German Interleaved 2/5
encodes either 11 or 13 characters. The characters
available for the data field are 0 through 9 (hex 30
through 39).
Terminates the bar code command. Enter the
SFCC for your VGL configuration immediately
followed by any valid command character or G, the
universal sequence terminator.
