Barcode FAQ & Tutorial
MicroPDF417 is two-dimensional (2D), multi-row symbology, derived
that encodes up to 150 bytes. Micro-PDF417 is designed for applications
requiring improved area efficiency, and is used for
Composite Codes in GS1 DataBar. IDAutomation provides Micro-PDF417
capability in all products that support DataBar, including the
Barcode Label Software,
.NET Windows Forms
Server for IIS and the
Java Barcode Packages.
Specifics about the symbology are as follows:
X and Y Dimension:
The X dimension is the width of the narrowest bar in the symbol. The
Y dimension is the height of each row within the symbol. The ratio of
X to Y is usually in the range from 1:2 to 1:5, where 1:3 is the most
commonly used ratio.
- Text Compaction permits all printable ASCII characters 32 - 126
and ASCII 9, 10 and 13.
- Binary Compaction permits all 256 ASCII values.
- Numeric Compaction permits efficient encoding of numeric data.
- Text - 250 characters if all characters are uppercase. In text
compaction mode, the amount of data that may be encoded varies due to
mode switching between numbers, upper case, lower case, punctuation
and other types of characters.
- Binary - 150 characters
- Numeric - 366 digits (when the data is numbers only).
Number of data columns: 1 - 4.
Number of rows: 4 - 44 in defined combinations with the number
Printing & Generating MicroPDF417 Barcodes
Several methods are available that enable generation and printing
of MicroPDF417 barcode symbols:
Reading MicroPDF Barcodes
The most common method of
decoding symbols is with a hand-held
PDF Capable Barcode Scanner. Because MicroPDF417 is not a common
symbology, most barcode scanners must be configured from the manual
before they will read and decode the symbols.
In some cases, it may be desired to have the scanner trigger a form
or action in an application. IDAutomation has documented easy methods
of accomplishing this in the
USB Barcode Scanner
Application Integration Guide.
