The maximum value is 5 multiplied by the X dimension. Optional. Sets the Y dimension of the module (white or black rectangle) in 100th of an inch. Notes: • The range of values for the Y dimension is between 2 and 5 times the value of the X dimension. Values beyond this range are clipped and set to the minimum and maximum values. • The default width of this element from the bar code engine is twice that of the X dimension. You need a value of 18.9 (1890 dec or 07 62 hex) to set the Y dimension to its default at 600 dpi. • The Units enumeration is set to 02 or 00 hex, and these two bytes are 07 and 62 hex. If unspecified, then the Y dimension doubles that of the X dimension. Rows Columns Rows: 4-44 dec Columns: 1-4 dec 0 dec 00 (hex) Optional. Manually set the number of symbol rows and columns.
