Code 93 was designed to complement
and improve upon Code 39. Code 93 is similar in that it, like Code 39, can
represent the full ASCII character set by using combinations of 2 characters.
It differs in that Code 93 is a continous, variable-length symbology and
produces denser code.
Code 93 offers higher information density for alphanumeric data than either
Code 39 or Code 128.
The * (asterisk) is not a true encodable character, but is the
start and stop 'symbol' for Code 93.
Sample of a Code 93 Barcode
In order to get a Code 93 barcode image, please follow these
steps:
-
Set the Symbology property to Code93
-
Set the AddChecksum property to False
-
By default, Code 93 can only encode uppercase letters (A through Z), digits (0
through 9) and a handful of special characters like the *, -, $, %, (Space), .,
/, and +. If you need to encode all 128 ASCII characters, please set the Extended
property to True
-
Setting up dimensions and quiet zones:
-
Set the BarWidth and BarHeight properties (Values are expressed
in Inches)
-
Set the QuietZoneWidth property (Value is expressed in Inches)
-
Set the TopMargin and BottomMargin properties (Values are
expressed in Inches)
-
Set the Code property with the value to encode.
-
Code 93 utilizes asterisk characters as Start & Stop symbols and they
are shown in the human readable text of a barcode image. You can rid of those
characters from the human readable text by setting up the DisplayStartStopChar
property to False
