Prefer Rectangular Symbols (preferRectangularSymbols)
The Prefer Rectangular Symbols property indicates whether rectangular symbols are enabled.
The data-matrix bar code is usually quadratic, and any code value can be represented by a quadratic symbol. If you are concerned about running out of space in the vertical of the page, you might prefer a symbol that is wider than it is high. This property produces a rectangular shaped symbol if the encoded data does not exceed 49 code words.
Type: Boolean.
Default value: FALSE (rectangular symbols are not enabled).
You can find the Prefer Rectangular Symbols property in the Bar Code category of the Properties view.
