TPDF417_Rows = 3 .. 90;
property MinRows: TPDF417_Rows;
The property specifies the minimum number of stacked rows for a PDF417 barcode symbol. It can be one of values from 3 to 90. They are defined in the pfmxPDF417Custom unit.
The minimum number of stacked rows together with the minimum number of columns (specified by the MinColumns property) indicates the minimum symbol size for a PDF417 barcode symbol. And the maximum number of stacked rows (specified by the MaxRows property) together with the maximum number of columns (specified by the MaxColumns property) indicates the maximum symbol size for the PDF417 barcode symbol. Based on the stretch order (specified by the StretchOrder property), the smallest symbol size that accommodates the barcode text will be automatically selected between the minimum symbol size and the maximum symbol size.
The CurrentRows property can be used to get the factual number of stacked rows.
Note, if the property is set to a value greater than the MaxRows property's value, the MaxRows property will be automatically changed to equal to this property's value. In other words, the MinRows property's value is always less than or equal to the MaxRows property's value.
