[. . . ] This is important for applications where a barcode must be more than merely an identifier, an index to reference a database. The portable data file approach is well suited to applications where it is impractical to store item information in a database or where the database is not accessible when and where the item's barcode is read. Because a PDF417 symbol can store so much data, item data such as the content of a shipping manifest or equipment maintenance history can be carried on the item, without requiring access to a remote database. Encoding data into a PDF417 barcode is a two-step process. First, data is converted into codeword values of 0-928, which represent the data. Then the values are physically represented by particular bar/space patterns, which is low-level encoding. In addition, PDF417 is an error-correcting symbology designed for real-world applications where portions of labels can get destroyed in handling. It performs error correction by making calculations, if necessary, to reconstruct undecoded or corrupted portions of the symbol. PDF417 Symbol Description At first glance, a PDF417 symbol looks like a set of stacked barcodes. When we look closer to analyze how the symbol is put together, there are several key elements. These are rows, start patterns, stop patterns, codewords, and modules, whose definitions are explained below. module The narrowest width of a bar or space in the barcode. All bars or spaces are multiples (up to six times) of this width. Moves the cursor from the current to a specified relative position. Moves the cursor to a position relative to the top and left edge limits of the page. Sets the unit of measurement used in the PRESCRIBE commands including the above. The other units are related to inches as: 1 inch=2. 54 centimeters=72 points=300 or 600 dots (depending on the printing system model). Limitations of Two-dimensional Barcode Item Encodable character set Code type Character self checking Bi-directional decoding Number of row indicator codewords required per row Number of symbol checksum codewords required Minimum number of rows per symbol Maximum number of rows per symbol Minimum number of data columns Maximum number of data columns Number of symbol length descriptors required Smallest nominal element width Smallest nominal element height Maximum data characters per symbol Description 256 international characters and binary data Continuous Yes Yes 2 2 3 90 1 30 1 0. 0075 inch or 0. 191 mm 0. 01 inch or 0. 254 mm Assuming 928 codewords ­ 1 symbol length descriptor ­ 2 symbol checksum codewords = 925 data codewords. Extended alphanumeric compaction mode (EXC): 1850 ASCII characters. Numeric compaction mode: 2725 digits. For Macro PDF417, which transparently distributes information among a number of PDF417 symbols, the above storage limits are increased to more than one million bytes in Binary/ASCII Plus mode and morethan 2. 5 million bytes in EXC mode. 5-13 Chapter 5 Barcodes Macro PDF417 Macro PDF417 provides a powerful mechanism for creating a distributed representation of files too large to be presented by a single PDF417 barcode. Macro PDF417 barcodes differ from ordinary PDF417 barcodes in that they contain additional control options which are added by modes 10 through 19 of the XBCP command. This allows a reader to make use of this information to correctly reconstruct and verify the file, independent of the barcode scanning order. The terminology PRESCRIBE macro and macro PDF are not the same. Refer to the PRESCRIBE Commands Command Reference for the PRESCRIBE macro commands (MCRO, ENDM, etc. ). The following modes of XBCP are used for Macro PDF417 to represent additional control options for XBAR. [. . . ] Ex: << /DeviceRenderingVividInfo << /VividColor bool >> >> setpagedevice bool (true: Vivid mode on, false: Vivid mode off) Controls RGB emulation. Ex: << /DeviceRenderingRGBInfo << /VirtualColorDevice << /ColorTransform name >> >> >> setpagedevice name /sRGB << /DeviceRenderingRGBInfo << /VirtualColorDevice null >> >> setpagedevice RGB emulation is not performed. Ex: << /DeviceRenderingCMYKInfo << /VirtualColorDevice << /ColorTransform name >> >> >> setpagedevice name /SWOP /EURO /Normal: Normal ink simulation << /DeviceRenderingCMYKInfo << /VirtualColorDevice null >> >> setpagedevice Does not perform ink simulation.

If tray numbers are omitted ([ ]), all trays are used. [. . . ]
