What is new in this release?

The latest version of Aspose.BarCode for .NET7.0.0 has been released. We have added support of CompactPDF417 code decoding. The Compact PDF417 is referred as Truncated PDF417 in previous standards. Compact PDF417 may be used where space is a primary concern and the symbol damage is unlikely, such as in an office environment. It removes the right row indicator, and reduces the stop pattern into a single bar. Micro QR code is a smaller version of the QR code standard for applications where symbol size is limited. We have added its encoding support. In the previous version, we have already added its decoding support. Many other enhancements are added to QR encoding. Users can now encode QR codes in ECI mode. It also encodes a multi-ECI and FNC1 symbols. In this new release version, we have improved OneCode and SwissPostParcel encoding areas. Previously, users were able to encode incorrect text in OneCode symbology but now it displays a proper error message. Similarly, in case of SwissPostParcel code, Aspose.BarCode APIs were adding ?98″ text at the start whereas parcels always start with ?99.42″. We have fixed it. The major areas include encoding and decoding enhancements, incorrect reading fixes of various code symbologies, enhancing of the barcode image, improve accuracy of recognition, incorrect letters in code text and improve recognition performance. Below is the list of new and improved features supported in this version.
