RotateTransform函数在船舶仪表控件编写中的运用及数学分析

Application and Mathematical Analysis of the RotateTransform Function on Programming Ship's Meter Control

应用最新的GDI+和Visual C#.net编程技术中的旋转函数Rotate Transform()法和计算坐标的方法来编写了船舶仪表控件中的电流表,介绍了两种不同编写方法的思考路径,阐述了这两种编写转动仪表控件方法的优点和缺点。

The Amperometer control,involved in this article,has been programmed by means of calculating coordinate and the RotateTransform function.Some virtue and flaw of these methods on programming rotational control is introduced.Two method presented in this article can be applied to other controls too.
