点阵字体文件查看器 c#(HZK16)
在MCU项目中，准备自己写个简单的UI，在中文文字显示，打算选择 UCDOS 中的 HZK16，为了查看字体文件，用C#写了个简单的查看器，并导出数据为C语言数组（因为所用的STM32F103VET片内flash有512K，可以容纳字库，不用外接SPI Flash了）。
源程序下载：http://download.csdn.net/detail/mostone/6024943
OS：windows 2008 R2 standard (zh-cn)
IDE：Microsoft Visual Studio Express 2012 for Windows Desktop - Microsoft Visual C# 2012
两个点阵字体下载链接：
常用的几个字体库---ASC16、HZK16、HZK12,附HZK16的使用资料
16*16点阵中文字库BIN文件
先上几张图：
查看器有两个 Form，一个是主画面，一个是选择字体对话框。布局如上图，下面是两个源代码：
