Columns

Type: SHORT

Default:        1

This value specifies the number of column units used in generating the barcode for those barcode types that support specified symbol sizes (Datamatrix, PDF417 or Databar (Expanded stacked)  barcodes). It is ignored for other barcode types.

For Datamatrix symbols the value determines the number of columns in the symbol. If the value is zero or less than the smallest symbol that can hold the data then the number of columns is determined by the data and the security level setting.

For Databar Expanded stacked symbols the value represents the width of the symbol in segment pairs.

For PDF417 symbols the value is the number of dataword columns that the control will attempt to fit the barcode image. It is important to note that not all values are possible (for example PDF barcode must have at least 3 rows).
