barcode reading software
PDF-417 barcodes are a common type of 2-D barcode and are designed to store more data than a 1-D barcode with built in redundancy and error correction. A PDF-417 barcode actually consists of stacks of 1-D barcodes arranged in columns. Each of the 1-D barcodes is called a cluster and has a numeric value. The …
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 …
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 …

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 …
