ITF ( I nterleaved T wo of F ive) is a continuous two-width barcode symbology whose simplest varieties are capable of encoding only numeric data.

This class extends its ancestor with members that allow you to (in those barcode symbology classes that publish them):

Specify if the checksum character is calculated and added to the encoded text displayed by a barcode control (Checksum);
Modify the barcode’s wide/narrow bar width ratio (WideNarrowRatio);

The TdxBarCodeITFTypeSymbology class is the direct ancestor of the TdxBarCodeInterleaved2Of5Symbology, TdxBarCode39Symbology, and TdxBarCode11Symbology classes.

You do not need to create instances of the TdxBarCodeITFTypeSymbology class. Use its descendants instead.
