IDAutomation provides several Barcode Components with support for multiple symbologies. This page provides helpful information for various symbologies available within IDAutomation Barcode Components.
The "AUTO" setting for Code 128 will automatically switch character sets as necessary to compact numbers in character set C and encode functions in character set A. The IDAutomation implementation of Code 128 auto offers many options when ApplyTilde is enabled:
|POSTNET, PLANET and Intelligent Mail||The X Dimension (or NarrowBarWidth) of 0.045 CM or 19 MILS should be used for all USPS barcode symbologies. For barcodes to be accepted by U.S. Post Offices, they must be between 22 and 24 bars per inch. The setting of 0.045 CM or 19 MILS should produce about 23 bars per inch. If results are different, adjust this property accordingly. To adjust the size of Intelligent Mail, the ascender, descender and full bar heights are all a function of the tracking bar height, which is controlled with the PostnetHeightShortBar property.|
UPC-E, EAN-8 and
|The text size and font may need to be adjusted with these barcode symbologies depending on the implementation and resolution. The +2 and +5 add-on codes may be encoded by appending them to the end of the data to encode string. If the check digit is added, it will be ignored and regenerated to ensure that the code can be scanned. The margins may need to be increased when using these symbologies.|
|UCC128||This symbology option encodes an even number of number digits and includes an FNC1 character in set C. Code 128 Auto must be used to encode additional FNC1 codes or data containing text or odd numbers. Use the UCC128 function only for GS1-128 applications where the input data is an even number and only one AI is needed, such as in SSCC-18 and SCC-14 barcodes.|
