Refer to Java PDF 417 image setting to know more details on how to adjust the PDF 417 valid data using Java.

Java PDF 417 supports changing the size of measure unit, image width and height, bar module size and margins and allows orientation to be changed among 0, 90, 180 or 270 degrees. Using this product, PDF 417 may be easily created in Java applications, Java Class, J2EE web applications as well as in Java Reporting projects.

PDF 417 Introduction

PDF 417, also known as Portable Data File 417, PDF 417, PDF417 Truncated, is a stacked linear barcode symbol format used in a variety of applications, primarily transport, identification cards, and inventory management. PDF stands for Portable Data File. The 417 signifies that each pattern in the code consists of 4 bars and spaces, and that each pattern is 17 units long.

Valid Data Set to Encode PDF 417 in Java

• Standard ASCII Characters: 0-127;
• Extended ASCII Characters: 128-255.

Valid Data Length in Java

As one of the three 2D barcode generator, Java PDF 417 is also can encode variable data length to make superb quality 2D barcode PDF 417 images in Java development.

For PDF 417 data encoding with Java, there are four data modes for various data encoding requirement to choose to set as following.

Encode Only Text Data for Java PDF 417

Text Compaction mode of Java PDF 417 generator permits all printable ASCII characters to be encoded, i.e. values 32 - 126 inclusive in accordance with ISO/IEC 646 (IRV), as well as selected control characters.

      DataMatrix barcode = new DataMatrix();

      barcode.setData("Java-Pdf417");

Encode Only Byte Letters for Java PDF 417

Byte Compaction mode of PDF 417 permits all 256 possible 8-bit byte values to be encoded. This includes all ASCII characters value 0 to 127 inclusive and provides for international character set support.

      DataMatrix barcode = new DataMatrix();

      barcode.setData("Onbarcode");

Encode Only Numeric Digits for Java PDF 417

Numeric Compaction mode of Java PDF 417 permits efficient encoding of numeric data strings.

      DataMatrix barcode = new DataMatrix();

      barcode.setData("417417417");

Encode Auto Data Mode for Java PDF 417

Auto data mode is de the default data mode for 2D barcode PDF 417 generation in Java programming and can encode all ASCII data to create PDF 417 images in Java.

      DataMatrix barcode = new DataMatrix();

      barcode.setData("PDF 417");

The storage capability of each PDF 417 valid data set can be shown as following.

• Text data: 1,850 characters


• Byte data: 1,108 characters


• Numeric data: 2,710 characters
