PDF417

This topic describes how to insert a barcode control of the PDF417 symbology (code type) into a report. In addition, it gives a short description of the PDF417 code type. To learn more about barcodes in XtraReports see the Barcodes Overview topic.

PDF417 (Portable Data File) is a stacked linear two-dimensional barcode used in a variety of applications; primarily transport, postal, identification card and inventory management. It was invented by Ynjiun Wang at Symbol Technologies in 1991, and has spawned an Open Source decoder project together with an Open Source encoder. The PDF417 barcode is also called a symbol barcode and usually consists of 3 to 90 rows, each of which is like a small linear bar code. For more information on this symbology, refer to its Official Standard web page.

The following properties should be set to specify a particular barcode of the PDF417 type:

• XRBarCode.AutoModule. This property determines whether the XRBarCode.Module property value should be calculated automatically based upon the barcode's size.
• PDF417Generator.Columns. This property determines the number of barcodes columns, which allows control of the logic width of the barcode.
• PDF417Generator.CompactionMode. This property allows you to choose whether textual information or a byte array should be coded.
• PDF417Generator.ErrorCorrectionLevel. This property determines the amount of redundancy built into the coding, to compensate for calculation errors. The correction system is based on "Reed Solomon" codes.
• PDF417Generator.Rows. This property determines the number of barcode rows, which allows control of the logic height of the barcode.
• PDF417Generator.TruncateSymbol. This property allows you to choose whether the special "end symbol" should be drawn.
• PDF417Generator.YToXRatio. This property determines the height-to-width ratio of a logical unit's graphic representation.
