2-D barcode formats such as PDF-417 can encode a huge character set, which means that the barcode reader toolkit needs to encode characters outside the normal ASCII range. If the Encoding property is set to 2 then the toolkit will use Unicode encoding, whereby characters can be represented by the string &#N; where N is
Delphi 2009 developers may have found some problems passing strings to and from the toolkit. This seems to be down to unicode support in Delphi 2009 and can be resolved with some simple code changes. For example, in previous versions of Delphi you might have code similar to: NumCodes:=stScanBarCode(PChar(OpenDialog1.FileName)); …but in Delphi 9 this needs
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
