This document explains how the properties of the toolkit can effect the speed at which PDF documents are processed. The PDF extension allows you to read barcodes from PDF documents. Version 7.4.1 or later… Version 7.4.1 introduced a faster and more accurate method of processing image-only PDF documents (e.g, a PDF document generated as the
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;
This arcticle shows some simple VB.net code snippets that reference the .net component or com object for the SDK in Visual Studio. .NET Managed Class Library with Visual Studio 2003 ‘Add a reference to SoftekBarcodeLib.dll Dim barcode As SoftekBarcodeLib.BarcodeReader barcode = New SoftekBarcodeLib.BarcodeReader ‘Set properties barcode.ReadCode128 = True ‘Read barcodes nBarCodes = barcode.ScanBarCode(Path) ‘Get results
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

The following code shows how the Softek barcode Reader Toolkit can be used from Borland Delphi to extract barcode information from images and memory bitmaps. Click here for some tips on using the toolkit with Delphi 2009. Click here to download a Borland Delphi example in a zip file. The following code was kindly provided by Marian Aldenh?vel of
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
