C39Tools is a collection of fonts that allows you to create Code 39 (Code 3 of 9) bar codes. C39Tools can be used to create regular Code 39 bar codes as well as Full ASCII Code 39 bar codes. You cannot simply type directly in the fonts and create a valid symbol. The c39tool command line utility accepts a string, formats it to include the start and stop bars, and converts any lowercase or control codes in the input into the correct Full ASCII Code 39 symbol characters. The string it returns is to be formatted in one of Azalea Software’s Code 39 bar code fonts. |

The point size you use determines the height of the bar code. If you format a string of the text at 36 points, the bars will be 1/2" tall and if you format a string at 24 points, the bars will be 1/3" tall. The overall width of the symbol depends on which of the 27 individual fonts in C39Tools you use. Some fonts create wider or narrower symbols than others. Simply change among the various fonts to see which one works best for you. There are three families of fonts in C39Tools : Narrow, Regular, and Wide. Each font family has a different wide bar to narrow bar ratio. The Narrow fonts have a 2:1 wide:narrow ration, the Regular fonts have a 2.5:1 ratio, and the Wide fonts have a 3:1 ratio. Within each of the three font families, there are nine individual fonts. These nine fonts have different overall height to width ratios. For example, Code39Regular-E is 50% wider than Code39Regular-D. Code39Regular-F is twice as wide as Code39Regular-D. The table below lists the ratio between the width of the various fonts, assuming Code39 is the base font. |

Code 39’s standard character set included 44 characters. C39Tools also supports Full ASCII Code 39 symbols. Full ASCII Code 39 is used to create the lower 128 ASCII characters. This is done by using pairs of characters to create the characters outside of the standard 44. Make sure that your scanner supports Full ASCII (most do). You may have to reconfigure your scanner. |
