Bar Code Field:
A bar code field makes up an imaginary box sufficiently large to accommodate
the bar code interpretation, regardless if it will be printed or not
(provided that the selected type of bar code may include an interpretation
at all).
However, for EAN and UPC codes, the box is restricted in regard of width
by the size of the bar pattern, not by the interpretation. This implies that
the first digit of the bar code interpretation will be outside the imaginary
box:
For composite bar codes, the human readable bar code interpretation for
the 2-dimensional element is outside the imaginary box.
Image field:
The size of an image field is decided when the field is created. Note that an
image field consists of the entire area of the original image, even possible
white or transparent background.
