(TBarcode2D_AztecCode)
The property is an advanced feature which allows low level control over data encoding for an Aztec Code symbol.
property BytesAlwaysBackToUpper: Boolean;
In the Aztec Code symbology specification, at the end of bytes mode, the encoding mode returns to the mode from which bytes mode was shifted into. For some readers, the encoding mode always returns to the upper mode, change the property to true in order to ensure barcode symbols can be read by these readers.
Please use your reader to read the following symbol, if the output text is "~~~a9a9a9TTT", please set the property to true, if the output text is "~~~a9a9a9\\\", please set the property to false.
