标签:ati lock 封装 blend transform tps soscw 今天 htm 今天来点实际的,项目中可以真实使用的,一个Loading的动画,最后封装成一个控件,可以直接使用在项目中,先上图: 整个设计比较简单,就是在界面上画18个Path,然后通过动画改变OpacityMask的值来实现一种动态的效果. 因为整个过程比较简单,所以其实没有用到Blend,唯一一个需要注意的是Path的路径值是请美工从PS里生成的,路径如下: Path的代码如下,每个Path一次旋转特定的角度围成一个圆形 单个Path的动画: 源代码下载: http://files.cnblogs.com/youngytj/LoadingAnimations.rar WPF和Expression Blend开发实例:Loading动画 标签:ati lock 封装 blend transform tps soscw 今天 htm 原文地址:https://www.cnblogs.com/lonelyxmas/p/9525232.htmlGeometry x:Key="Block">
