WPF - 之对象变形
WPF（Windows Presentation Foundation）是一个用于构建客户端应用程序的图形界面库，它提供了许多对象变形（Object Transformation）的功能。这些功能可以让你轻松地改变对象的大小、位置和角度，以实现各种视觉效果。以下是一些常用的 WPF 对象变形技术：[*]TranslateTransform：用于平移（移动）对象。你可以使用 TranslateTransform() 构造函数创建一个平移变换对象，并使用 X 和 Y 属性来设置平移的距离。
TranslateTransform translateTransform = new TranslateTransform(10, 20);
myRectangle.RenderTransform = translateTransform; 2. ScaleTransform：用于缩放（放大或缩小）对象。你可以使用 ScaleTransform() 构造函数创建一个缩放变换对象，并使用 ScaleX 和 ScaleY 属性来设置缩放的比例。
ScaleTransform scaleTransform = new ScaleTransform(2, 0.5);
myRectangle.RenderTransform = scaleTransform; 3. RotateTransform：用于旋转对象。你可以使用 RotateTransform() 构造函数创建一个旋转变换对象，并使用 Angle 属性来设置旋转的角度。
RotateTransform rotateTransform = new RotateTransform(45);
myRectangle.RenderTransform = rotateTransform; 4. SkewTransform：用于倾斜（倾斜）对象。你可以使用 SkewTransform() 构造函数创建一个倾斜变换对象，并使用 AngleX 和 AngleY 属性来设置倾斜的角度。
SkewTransform skewTransform = new SkewTransform(30, 60);
myRectangle.RenderTransform = skewTransform;以上只是 WPF 对象变形技术的一部分，还有更多高级的变换可以应用于各种效果，如组合变换、矩阵变换等。
一、RenderTransform特效（变形）WPF中的变形（RenderTransform）类是为了达到直接去改变某个元素对象的形状的目的而设计的，它可以实现对元素缩放、拉伸，旋转，扭曲等效果，同时变形特效也常用于辅助产生各种动画效果。RenderTransform类：该类成员如下：TranslateTransform：能够让某对象的位置发生平移变化。RotateTransform：能够让某对象产生旋转变化，根据中心点进行顺时针旋转或逆时针旋转。ScaleTransform：能够让某对象产生缩放变化。SkewTransform：能够让某对象产生扭曲(斜角)变化。TransformGroup：变换集合,能够让某对象的缩放、旋转、扭曲等变化效果合并起来使用(组合多个变换)。MatrixTransform：能够让某对象通过矩阵算法实现更为复杂的变形。通常，对于使用RenderTransform属性比使用LayoutTransform属性更好，整理的图像变形代码实例，加入很多代码注释<Grid>
