How do PDF-417 Barcodes Work? PDF-417 barcodes can pack more data into the same space than conventional 1-D barcodes, and are very useful for applications that need to encode more than 20 characters in a barcode. A PDF-417 barcode is split into columns, guarded by 5 black bars on each side, and each column is …
Here are some examples of the good, the bad and the ugly of the barcode world. The Good: Code 39 Code 25 Interlaced Code 128 EAN-8 EAN-13 UPC-A UPC-E The Bad and the Ugly: Example 1 – Too many asterisk characters. Example 2 – Extra character returned by toolkit Example 3 – A box around the barcode Example …
This article shows 2 simple visual c++ code snippets that use either the standard windows dll or the com object for the toolkit. Standard Windows DLL hBarcode = mtCreateBarcodeInstance() ; //Set properties mtSetReadCode128 (hBarcode, 1) ; //Read barcodes int nBarCodes = mtScanBarCode(hBarcode, m_ImageFile) ; //Get results for (int i = 1; i <= nBarCodes; …

The TifSplit feature of the toolkit allows you to use barcodes as document separators. The input file is scanned for barcodes and then split into a number of smaller documents. There are 2 properties that control how the input file is split: Setting TifSplitPath turns the feature on and controls where the new documents will be created. e.g c:\tmp\Output%d.tif will …

Example: Code 128 is one of the more complex linear barcodes, with a greater capacity than Code 25 or Code 39, but requiring better quality images for reliable recognition. Key features: 4 different width of bar/space. 3 symbol sets (A, B and C). Symbol set C encodes pairs of digits and is one of the …
Example: Code 2 of 5 is a popular barcode for encoding numeric data. Key features: 2 different width of bar/space. Symbol set consists of digits 0-9 Each character is made up of 2 wide and 3 narrow elements. Start sequence is narrow bar, narrow space, narrow bar, narrow space. End sequence is wide bar, narrow …
Example: Code 3 of 9 is the most popular barcode for encoding alpha-numeric characters. Key features: 2 different width of bar/space. Symbol set contains 43 characters: A-Z, 0-9, and -, ., *, $, /, +, %, SPACE. Each character is made up of 5 bars and 4 spaces with 3 wide bars/spaces and 6 narrow …
