Overview

PosiCode is a continuous, variable length, non-self-checking, bidirectional symbology that is usually used within printing processes where it is difficult to precisely control the width of a bar.

Invoking

• The data field can hold the following:
• For standard symbols: Any ASCII data
• For limited symbols: letters A-Z, digits 0-9, symbols - and .
• The version option is used to specify the variant of the symbol, either:
• version=a (default)
• version=b
• version=limiteda
• version=limitedb
• When the parse option is specified, any instances of ^NNN in the data field are replaced with their equivalent ASCII value, useful for specifying unprintable characters, e.g. ^029 for GS, etc.
• When the parsefnc option is specified, non-data function characters can be specified by ^FNC1 through ^FNC4.
• The inkspread option can be used to adjust the width of the bars.

Example PosiCode

Equivalent ways to generate a PosiCode A symbol:

0 0 moveto (Abc123) () /posicode /uk.co.terryburton.bwipp findresource exec

0 0 moveto (Abc123) (version=a) /posicode /uk.co.terryburton.bwipp findresource exec

PosiCode A including a GS (ASCII 29) character:

0 0 moveto (AB^029CD) (parse) /posicode /uk.co.terryburton.bwipp findresource exec

PosiCode A including an FNC2 special character:

0 0 moveto (AB^FNC2CD) (parsefnc) /posicode /uk.co.terryburton.bwipp findresource exec

PosiCode B symbol with widened bars:

0 0 moveto (Abc123) (version=b inkspread=-1) /posicode /uk.co.terryburton.bwipp findresource exec

Example Limited PosiCode

Limited PosiCode A with narrowed bars:

0 0 moveto (ABC-12.3) (version=limiteda) /posicode /uk.co.terryburton.bwipp findresource exec

Limited PosiCode B:

0 0 moveto (ABC-12.3) (version=limitedb) /posicode /uk.co.terryburton.bwipp findresource exec
