Barcode Integration Tutorial (Pre 2016 Release Only)

Create Barcodes in FileMaker 14

This tutorial is for the linear version of this product that is a set of FileMaker Custom Functions that generate barcodes without any other dependencies from an already installed system font such as Courier New. Later versions of the product should refer to the current user manual.

  1. Extract or decompress the files from the Native Barcode Generator package
  2. Open the database that is to generate the barcode and choose File - Manage Custom Functions.
    File - Manage Custom Functions
  3. Choose Import and then select the FileMaker database file that was extracted in Step 1.
  4. Select one function, then press Ctrl-A and the space bar to select the remaining functions. It is necessary to import all of the functions from the database because several of the functions depend on others to be present. Note: Failure to import all functions in this step will result in empty fields instead of barcodes.
    Selecting custom barcode functions.
  5. Choose File - Manage Database to create a calculated field that will contain the generated barcode. Name the field to be the same as the related function name, without the underscores. In this example, the field will be named IDAutomationNatCode128 and it will call the IDAutomation_Nat_Code128 function. For the field type, choose Calculation and choose Create.
    Creating the Code-128 calculated field.
  6. In the specify calculation dialog, change calculation result to text, choose the appropriate function from the list on the right, and replace DataToEncode with the field that needs to be encoded in the barcode and enter a number for BarHeight such as "8" that determines the height of the barcode.
    Specifying the calculation for Code128.
    Optional: The DataToEncode parameter may be changed to a formula that appends text to a field or combines multiple fields. For example:
    IDAutomation_Nat_C128( "PREFIX" & Field1 )
    or IDAutomation_Nat_C128( Field1 & "," & Field2 )
  7. Open the FileMaker database file that was extracted in Step 1. Change to Layout Mode and copy the example barcode field to the clipboard and paste it into the database that will generate the barcode.
  8. Right-click on this field and choose Specify Field; choose the calculated field created in step 5, in this case it is IDAutomationNatCode128.
    Select the Code128 field.
     
  9. Size the field so it will completely contain the desired barcode.
  10. Click on the field and open the Inspector Window, by going to View - Inspector:
    • In the Appearance section, verify the font selected is a mono-spaced system font such as Courier New, Lucida Console, Consolas and the Font Size is 4 points. Note: Courier New is the preferred font to use for linear barcodes and Consolas is the preferred font to use for 2D Matrix barcodes.
    • In the paragraph section verify the Line Spacing Height is a height of 0.99. If the barcodes will be displayed on mobile devices with FileMaker Go, set the Line Spacing Height to .95 to reduce horizontal whites lines that could appear in the barcode.
    • Verify the Alignment is Center so that an appropriate amount of white space appears around that barcode.

      The default point size of 4 generates a barcode X dimension at 12 mils in size. If it is necessary, the point size may be changed according to the following chart.
    Point Size Approximate X Dimension
    2 08 Mils
    3 12 Mils
    4 16 Mils
    5 20 Mils
    6 24 Mils
    7 28 Mils
    8 32 Mils
    Note: If the font drop-down box does not contain small sizes, the size must be manually typed in.
  11. Optional: If a text interpretation of the barcode is needed, it is suggested to place the appropriate field directly above or below the field that will contain the barcode. To automatically generate the human readable field for GS1-128, create another calculated field as noted in step 5 with the IDAutomation_Nat_Code128HR function.
  12. Save and view the form or report. Verify that the barcode symbol is being generated properly on all devices. In some cases, horizontal lines may appear in the barcode because of low screen resolution. However, the printed barcodes should be accurate without any visible lines. An adjustment to the line spacing property mentioned in Step 10 should resolve horizontal line issues. If a scanner is needed to verify printed barcodes, IDAutomation offers several affordable USB barcode scanners.

Creating GS1-128 Symbols

IDAutomation includes the capability in this product to create barcodes and HR text for GS1-128 (UCC/EAN128) symbols with the built-in ApplyTilde feature which is enabled by default. The following describes the changes required to implement GS1-128. This GS1-128 symbol example is created from 18 digits of numbers in the GS1DataField field.

Functions of the Linear Barcode Generator

DataToEncode is the only required parameter in the functions provided. Optional parameters are separated with the pipe "|" character and may be appended to the DataToEncode, for example IDAutomation_Nat_C39("TESTDATA" & "|3" ; 8)

2D Data Matrix Barcode Object Parameter Descriptions
DataToEncode, ApplyTilde, EncodingMode, PreferredFormat
Description of the Properties of the Functions:

DataToEncode

This is a string value that represents the data being encoded.

BarHeight

The height of the barcode. The recommended default is 8. The approximate height is determined with the following formula:
  Height in Inches = (Font Size) * (BarHeight) * 0.012
  Height in CM    = (Font Size) * (BarHeight) * 0.03

N_Dimension

Determines the width of the wide bars, which is a multiple of the X dimension. Valid values are 2 and 3. The default is 2.

IncludeCheckDigit

Determines whether a check digit should be automatically calculated and included for the DataToEncode. Valid values are 0 (false) and 1 (true). Default = 0 for Code 39 and Interleaved 2 of 5.

ApplyTilde

If ApplyTilde is set to 1 (true), the default value, the tilde will be processed. Set this to 0 (False) to disable this feature.
