## Discussion

Discussion This method generates a PDF417 barcode as an image. PDF417 is a high-density stacked linear barcode format defined in the ISO 15438 standard. Use this filter to generate alphanumeric or numeric-only barcodes. Commonly used on identification cards or inventory management because of the large amount of data the barcode can hold. The PDF417 barcode generator filter uses the following properties: The compactionMode property takes one of the following numeric values:  |  |   |  |   |  |   |  |   |  |  Select either 1 or the appropriate valid value for your data that gives the most compact output. The following code creates a filter that generates a PDF417 barcode: func pdf417Barcode(inputMessage: String) -> CIImage {     let pdf417BarcodeGenerator = CIFilter.pdf417BarcodeGenerator()     pdf417BarcodeGenerator.message = inputMessage.data(using: .ascii)!     pdf417BarcodeGenerator.minWidth = 56     pdf417BarcodeGenerator.maxWidth = 58     pdf417BarcodeGenerator.maxHeight = 283     pdf417BarcodeGenerator.minHeight = 13     pdf417BarcodeGenerator.dataColumns = 9     pdf417BarcodeGenerator.rows = 6     pdf417BarcodeGenerator.preferredAspectRatio = 0.0     pdf417BarcodeGenerator.compactionMode = 1     pdf417BarcodeGenerator.compactStyle = 1     pdf417BarcodeGenerator.correctionLevel = 0.01     pdf417BarcodeGenerator.alwaysSpecifyCompaction = 0     return pdf417BarcodeGenerator.outputImage! }
