Reading & Scanning PDF 417 Barcodes in Java class

Top

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. 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.

OnBarcode Java PDF417 Barcode Scanner supports reading Macro PDF417 barcodes in Java application. The demo Java source code below explains how to read and view the Macro PDF 417 data in Java web and desktop applications.

Use method isMacro() to check whether the scanned PDF417 is a Mcro PDF417 barcode.
Use method getMacroFileID() to get file ID. All Macro PDF417 barcode with the same file id are the parts of the same data message
Use method getMacroSegmentIndex() to get the order of the data message. The first segment index is 0.

BarcodeDetail[] result = BarcodeScanner.ScanInDetails(
		"macro-pdf417-image.png", BarcodeType.PDF417);
if (result != null && result.length > 0)
{
    for (BarcodeDetail b : result)
    {

        if (b.getType() == BarcodeType.PDF417)
        {
            PDF417Props props = (PDF417Props)b.getBarcodeProps();
            //  Indicate if it is a Macro PDF417.
            System.err.println("Is Macro PDF417: " + props.isMacro());
            if (props.isMacro())
            {
                //  Get segment index. Start from 0.
            	System.out.println("Segment Index: " + props.getMacroSegmentIndex());
                //  Get file identification in string format.
            	System.out.println("File ID:             ");
                //  A list of codewords. Each in range 0 ~ 899.
            	int[] macroFileIDs = props.getMacroFileID();
                if (macroFileIDs != null && macroFileIDs.length > 0)
                    for (int v : macroFileIDs)
                    	System.out.println("                     " + v);
                //  Indicate if this symbol is the last segment.
                System.out.println("Is Last Segment: " + props.isMacroLastSegment());
                //  Indicate if it contains optional fields.
                System.out.println("Optional Field Enable: " + props.getMacroOptFieldEnable());
                if (props.getMacroOptFieldEnable())
                {
                	System.out.println("File Name: " + props.getMacroFileName());
                	System.out.println("Segment Count: " + props.getMacroSegmentCount());
                	System.out.println("Timestamp: " + props.getMacroTimeStamp());
                	System.out.println("Sender: " + props.getMacroSender());
                	System.out.println("Addressee: " + props.getMacroAddressee());
                	System.out.println("File Size: " + props.getMacroFileSize());
                	System.out.println("Checksum: " + props.getMacroChecksum());

Common Asked Questions

What is PDF417 used for?

PDF417 is a high density, 2d stacked barcode format used in a variety of applications, such as driver's license, airline boarding pass ticket, transport, and inventory management. You could use OnBarcode Java Barcode Reader SDK to scan and decode text from PDF417 barcode images in Java desktop and web applications.

How to scan PDF417 barcode image?

You can use camera with barcode app installed on smartphone (iOS or Android), or barcode scanner device or software to scan, read PDF417 barcodes. Java Barcode Scanner library enables you to quickly integrate PDF417 barcode reading and decoding feature in Java class.

Can iPhone or Android phones scan PDF417 barcode?

With OnBarcode best-in-class Java PDF417 reader and scanner, you can scan, recognize and decode PDF417 codes using iPhone or Android mobile devices.

What is the difference between a PDF417 and a QR Code?

Both PDF417 and QR Code are two-dimensional (2D) barcode formats. PDF417 can be scannable even if up to 50% of it is damaged. QR Code can accept up to 30% damages. Java Barcode Reader library supports both PDF417 and QR Code 2d barcode reading and recognition.
