ECInitialize
- 实现了椭圆曲线的初始化,并当参数生成后,会对参数a和b进行判断,看是否符合椭圆曲线的要求。-realized the elliptic curve initialization, and when the parameters of the generated will parameters a and b for judgment to see whether they conform to the requirements of elliptic curves.
绘制半透明位图及如何画透明位图
- 绘制半透明位图及如何画透明位图 有的时侯,我们希望显示一幅半透明的位图。也就是说我们将一幅位图B 显示到A位图上,又希望透过B位图看到A位图的一部分图像但不是全部。比如A位 图是一幅曲线图,B是一幅提示位图,我们想在显示提示的同时看到已显示的曲 线,但不需要曲线的背景 ,就需有用到半透明位图。曲线看上去就象从B位图中渗 透过来,其实半透明技术就是一种渗透技术,渗透公式我们可选用多种,在这里 我们选用(A AND 0x7F)OR B。注意,白色不能产生渗透。-rendering transluce
