C#生成Code39(extend)条形码【非条形码字体】

Code39是条形码的一种。由于编制简单、能够对任意长度的数据进行编码、支持设备广泛等特性而被广泛采用。

能够对任意长度的数据进行编码。其局限在于印刷品的长度和条码阅读器的识别范围。
支持设备广泛。目前几乎所有的条形码阅读设备都能阅读Code39码，打印机也是同样情况。
编制简单。简单的开发技术就能快速生成相应的编码图像。
一般Code39码由5条线和分开它们的4条缝隙共9个元素构成。线和缝隙有宽窄之分，而且无论线还是缝隙仅有3个比其他的元素要宽一定比例。39码因此得名

Code39条形码规则

　　1、每五条线表示一个字符；　　2、粗线表示1，细线表示0；　　3、线条间的间隙宽的表示1，窄的表示0；　　4、五条线加上它们之间的四条间隙就是九位二进制编码，而且这九位中必定有三位是1，所以称为39码；　　5、条形码的首尾各一个 * 标识开始和结束。Code 39只接受如下43个有效输入字符：　 1、26个大写字母（A - Z），　 2、十个数字（0 - 9），　 3、连接号(-),句号（.）,空格,美圆符号($),斜扛(/),加号(+)以及百分号(%)。 4、其余的输入将被忽略。　 5、code39通常情况下不需要校验码。但是对於精确度要求高的应用，需要在code39条形码後面增加一个校验码。条形码的生成网上也有很多库文件，做的特别好的都是商业授权。一维码二维码在.net开源项目中的生成读取比较知名的有:Zxing.net(http://zxingnet.codeplex.com/)、BarcodeLib等但有些时候开源软件所实现的并不满足当下的需求，所以还要做一些其他尝试。效果如下图：
