barcode reading software
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 SDK can be used to convert from TIFF to PDF format as part of the “tiff split” functionality. If the input file for the ScanBarCode method is in TIFF format and the TifSplitPath property is set to a value ending with “.pdf”, then the toolkit will split the input file into sub-files in PDF …
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 …
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 …
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; …
