Barcode.ImageHeight the height of the image in HIMETRIC units (ie. 0.01 mm units)
Barcode.ImageWidth the width of the image in HIMETRIC units (ie. 0.01 mm units)
The ImageWidth property will be either the value provided before the Picture was created, or, if a non-zero value of Xunit has been provided, the value calculated from the Xunit value and the number of elements in the barcode.
These values may be used to determine the size at which the barcode Picture is displayed or printed.
