This function will take the data you provide it and generate a barcode image in PNG, EPS, or SVG format.

Required Parameters

This specifies the type of barcode to generate. Valid values are “Codabar”, “Code39”, “Code39+”, “Code93”, “Code128”, “Databar14”, “Databar14Stacked”, “DataMatrix”, “EAN”, “EAN14”, “EAN18”, “EAN128”, “HIBCDataMatrix”, “Interleaved2of5”, “ISBN”, “USPS OneCode”, “PDF417”, “Postnet”, “QRCode”, “UPCA”, or “UPCE”.


This is the data to encode into the barcode. If you specify a Number field, the plug-in will auto-format it with four decimal places. However, if the fractional part is zero, it will be removed leaving only the whole number. If you need any other formatting for Numbers, you will need to convert it to text within FileMaker before sending to this function. If the barcode supports it, you can encode control characters either directly with \0, \b, \f, \n, \r, \t, \v, \xXX or by using the Unicode “Control Images” [code points 0x2400–0x2421; Char ( 9216 ) - Char ( 9249 ) ]

Optional Parameters

The output Format of the Barcode Image. Valid values are “PNG” (the default), “EPS”, or “SVG”.


The format the data is interpretted as when generating the barcode. Valid values are “Unicode” [the default], “Binary”, or “GS1”.

This generates a QR Code with an embedded URL to the CNS Plug-ins website.

CNSBC_Generate( "QRCode" ; "" )
Example 2

This generates a UPC A barcode.

CNSBC_Generate( "UPCA" ; "03506152005" )
