DelphiZXingQRCodeEx
===================

DelphiZXingQRCodeEx is a Delphi port of the QR Code functionality from ZXing, an open source barcode image processing
library.

The code was initially ported to Delphi by Senior Debenu Developer, Kevin Newman (project *DelphiZXingQRCode,* see links
below). Then it was changed by Michael Demidov. The changes are listed in CHANGELOG.md.

**The most fundamental differences are:**

1. Error correction level has been fixed.
2. Support for programmer-defined charsets. As an example, I implemented Win-1251 Russian charset and URL encoding (when
non-Latin characters are represented as %-codes).
3. Exception handling has been added. There is no more Access Violation when input string is too long.
4. New *QRGraphics.pas* unit has been added that contains several functions to draw the QR Code on a given canvas (*TCanvas*) and
to generate either a bitmap or a metafile.
5. Still compatible with older versions of Delphi (at least Delphi 7). Compatible with Lazarus (1.2.6, for Windows),
see CHANGELOG.md (section 5).

The port retains the original Apache License (v2.0).
