When distributing SoftekBarcodeLib2.dll you may find that you get a “side by side” error message which references the component. For Version 7.4.1 and later… For x86 based systems, the solution is to install the Microsoft Visual C++ 2008 SP1 Redistributable Package (x86) from the following link: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=a5c84275-3b97-4ab7-a40d-3802b2af5fc2&displaylang=en For x64 based systems, the solution is to install the Microsoft
This article explains how to correlate the output files produced during a tiff split process against the barcode values returned by GetBarString. The algorithm shown here assumes default split mode (TiffSplitMode = 0) and handles multiple barcodes on a single page and the possibility of no barcode on the first page. The code below uses
The graph below is a representation of a single scan line bisecting the image of the barcode shown underneath. The scale on the Y-axis represents pixel values with distance in pixels on the X-axis. Note that the value of a pixel is derived from the RGB value using the formula (R + G + B) / 3. The
RSS Expanded is capable of storing 74 numeric or 41 alphabetic characters and is normally used in point of sale retail applications. The Softek Barcode Reader SDK will support RSS Databar from January 2010. IIS = Item identification string (including a mod-10 check-digit at end of string) The mod-10 check-digit is calculated from a 13 digit
As the toolkit scans the images in a document, it assigns a “hit-count” to each barcode-like pattern it finds. The hit-count for a very clear barcode will typically be in the region 20 to 100, depending on the size of the barcode and the settings used within the sdk. The PrefOccurrence and MinOccurrence properties specify hit-count levels

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
UPC-A barcodes are a subset of EAN-13. For example, the UPC-A barcode “016000336100” is the same as the EAN-13 barcode “0016000336100”. In fact, UPC-A barcodes are the sub-set of EAN-13 barcodes that start with a 0. The ReadEAN13 property controls whether any barcodes of type EAN-13 are recognized – and this includes UPC-A, whether or
The SkewTolerance property is used for the detection of barcodes in skewed documents, but it can have a negative impact on the performance of the ScanBarCode command, especially when reading PDf-417 and Datamatrix barcodes. One solution to this problem is to use xml settings, which allow you to store sets of properties which are applied
