code-2-5-industrial

Details on the code-2-5-industrial bar code type.

The code represents a decimal number with a variable number of digits. The number of digits can be specified by setting the noDigits attribute. The last digit is the check character. The check character is calculated the same way as the ean 13 check sum.

The rightmost digit (checksum digit) can be omitted. When the system is supplied with a value that is one digit shorter than specified by noDigits then the check digit is automatically calculated by the system.

The nominal height is 1in. Each digit is drawn using a pattern of two wide and three thin bars yielding a total of 5 bars per digit. The nominal width of a thin bar is THINBARWIDTH=0.0236in. The width of a thick bar is THICKBARWIDTH=THINBARWIDTH/ thinToThickRelation where thinToThickRelation should take values between1/3 and1/2. Between digits a gap of the width GAPWIDTH=THINBARWIDTH/ thinToGapRelation (Thin To Gap Relation) is drawn. The padding on both sides measures 10*THINBARWIDTH.
