If you set PreferredFormat to 0 (Auto format), our Aztec ASP control 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 ASP control will also automatically choose an appropriate format with bigger data capacity to encode the string.
