If you set PreferredFormat to 0 (Auto format), our Aztec Win32 DLL will automatically choose an appropriate format with enough data capacity to encode the string.
If you set PreferredFormat to other values and the data capacity of the selected format is not big enough to encode the string, our Aztec Win32 DLL will also automatically choose an appropriate format with bigger data capacity to encode the string.
