  • Title - name of parameter (can be used for definition of document name or location), the title has to be different from system parameters
  • Type - OptimiDoc supports two types of parameter; the first parameter is text and second is a barcode.
  • Use as a document separator - if in the zone will be found the barcode the OptimiDoc use the page as a first one of new document (valid only for barcode type)
  • Text filter - use the filter to match string to the predefined value based on regular expression (valid only for text type)

Please refer to Character Classes in Regular Expressions or Wikipedia for more information about Regular Expressions.


Examples of regular expression:

    • Select number with length 5-10:
      • [0-9]{5,10}


Example:

      • Input Value:

456487

      • Result:

456487


      • Input Value:

123

      • Result:

nothing because the number does not fit to length


    • Search text "Date:" and take the date after the text
      • Date: ([0-9]{1,2}.[0-9]{1,2}.[0-9]{4})


Example:
