Macro PDF417 provides a mechanism for the data in a file to be split into blocks and be represented in more than one PDF417 symbol. This mechanism is similar to the Structured Append feature in other symbologies, like Data Matrix, QR Code.
Each Macro PDF417 symbol shall contain additional control information to enable the original data file to be properly reconstructed, irrespective of the sequence in which the individual PDF417 symbols are scanned and decoded. Here are list of important properties of Macro PDF-417 barcode
The steps and C# source code below show how to get the information of Macro PDF417 barcodes using C#.NET Barcode Reader library
public static void ReadMacroPDF417() { String imageFilePath = "..."; // scan all PDF417 symbols in the image file BarcodeDetail[] datas = BarcodeScanner.ScanInDetails(imageFilePath, BarcodeType.PDF417); for (int j = 0; j < datas.Length; j++) { // check if this is a Macro PDF417 Console.WriteLine(" Is Macro PDF417: " + datas[j].isMacroPDF417()); // get macro PDF 417 file id Console.WriteLine(" File id: " + datas[j].getMacroPDF417FileID()); // check if this is the last segment Console.WriteLine(" Is Last Segment: " + datas[j].isMacroPDF417LastSegment()); // get segment number (in String type) Console.WriteLine(" Segment Index: " + datas[j].getMacroPDF417SegmentIndex()); // get file ID (in String type) // Note: // All characters in this String is digital ASCII (that is 0 ~ 9) // Every 3 digits represent a number (which based on 900) Console.WriteLine(" File ID: " + datas[j].getMacroPDF417FileID()); if (datas[j].isMacroPDF417()) { // get data in the Macro PDF417 string barcodeSegmentData = datas[j].Data; // ... } } }
