Description

This script implements Code 39 barcodes. A Code 39 barcode can encode a string with the following characters: digits (0 to 9), uppercase letters (A to Z) and 8 additional characters (- . space $ / + % *).

Code39(float xpos, float ypos, string code [, float baseline [, float height]])

xpos: abscissa of barcode
ypos: ordinate of barcode
code: value of barcode
baseline: corresponds to the width of a wide bar (defaults to 0.5)
height: bar height (defaults to 5)
