C#+GDI+绘制的一个时钟，实现秒针，分针，时针的绘制。-A clock by Csharp and GDI+

C# 做LED效果，使用C#语言环境制作的LED显示屏效果，根据srcBitmap绘制desBitmap，获取源图的bmdata。定义时钟事件，设置文字样式等。-C# to do the LED effect, use the C# language environment produced by the LED display effect, according to srcBitmap to draw desBitmap access to the source map bmdata. De

运用坐标旋转算法计较坐标旋转后的新坐标值，以及此原理制作的电子时钟，整个时钟是用GDI绘图绘制而成。在DEMO中还可以手动输入旋转角度，绘制旋转后的直线。-Coordinate rotation coordinate values ​ ​ using the new algorithm rotated coordinate care, and this principle of making electronic clock, the whole clock is made
