Postnet & Planet Generation Options
The Postnet barcode function is specified in IDAutomation Barcode Fonts, Components and Applications to create a USPS Postnet or Planet barcode, which encodes numbers only. The DataToEncode is a single string of numbers and can include dashes and spaces.
The Postnet barcode function may also be used to format data to the Planet Barcode Font in the same way.
When using this function with the Universal Barcode Font, only the XS, S or M size of the font may be used. XS is the normal version, S has the bars narrow by 10% and the M font has the bars narrow by 20%.
