Type: SHORT
Default: 0
Allowed range: 10 - 255
The xunit property may be used to specify the width (in Mils) of the smallest element in the barcode.
Note that setting this property to a value other than 0 causes the control to resize itself to a width calculated from the number of X units in the barcodes. Using values smaller than 8 will produce a barcode image, but that image will not meet standard specifications and may not scan.
