本文将告诉大家如何在 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>WinUI3 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>里面使用 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Win2D <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>进行图片的翻转，本文的方法也适用于 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>UWP <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>框架
图片的翻转在 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Win2D <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>里面，可以使用 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Transform2DEffect <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>特效来辅助实现，核心逻辑就是通过缩放矩阵当成2D翻转矩阵，将缩放的 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>X <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>和 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Y <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>传入负数即可分别实现对应方向的翻转。比如左右水平翻转可将 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>X <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>值传入负数，如 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>-1 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>表示直接水平翻转
本文接下来将告诉大家一步步进行实现从文件加载图片，再将图片进行翻转在界面显示

请大家将上面代码的 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>C:\lindexi\Image\1.png <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>路径替换为你自己的本地图片文件的路径
以上代码写了一个名为 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>LoadImageAsync <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>的内部方法，这是因为加载图片需要用到异步，需要包装 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Task <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>作为异步任务，再将异步任务通过 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>TrackAsyncAction <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>告知给到 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Win2D <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>层。如此即可让 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Win2D <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>等待 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>LoadImageAsync <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>完成才完成资源创建逻辑，接着再执行 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Draw <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>绘制。如果没有使用 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>TrackAsyncAction <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>方式告知 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Win2D <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>的话，那可能在资源加载完成之前，就会进入到 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Draw <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>绘制导致状态不符合预期
换句话说，直接将 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Canvas_OnCreateResources <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>改为 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>async <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>void <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>是不可以的，一旦这么做了，那 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Win2D <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>层是无法感知到资源异步加载完成的，也就让 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Win2D <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>层无法知道在何时才是合适的触发渲染
完成图片资源加载逻辑之后，接下来进入到核心的 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Canvas_OnDraw <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>方法
图片的翻转在 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Win2D <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>里面，可以使用 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Transform2DEffect <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>特效来辅助实现，核心逻辑就是通过缩放矩阵当成2D翻转矩阵，将缩放的 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>X <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>和 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Y <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>传入负数即可分别实现对应方向的翻转。本文以下将演示如何将图片进行水平翻转。还请大家不用担心用到矩阵，本文这里不会直接用到多少矩阵知识，只是简单调用方法而已
先从字段 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>_canvasBitmap <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>获取 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>CanvasBitmap <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>类型的对象，保持稳定的话需要判断一次空，防止资源创建步骤出现诡异的事情导致没有创建成功

这里的中心点直接取宽度高度的一半是因为图片本身没有平移，且接下来的特效是基于当前图片的坐标系。相当于图片的左上角就是 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>0 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>0 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>点，直接取宽度高度一半就是刚好中心点的值

如此即可完成图片的左右翻转
有伙伴可能好奇，使用本文的特效方式对图片进行翻转，性能如何呢？答案是性能是特别高的，在 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Win2D <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>里面绝大部分特效对于 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>GPU <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>来说时间复杂度都是 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>O(1) <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>级，这是什么概念呢，用简单的话说就是 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>GPU <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>一口气就能做完，不耗资源的
以上就是本文提供的简单示例代码，在 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>WinUI <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>3 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>或 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>UWP <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>里面使用 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Win2D <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>进行翻转图片。本文以上的例子代码只是做水平左右翻转，相信阅读了以上内容的伙伴自己也能实现垂直翻转功能
再近一步，如果图片比较大或比较小，我想要再次缩放图片，让图片刚好在界面里面填充显示，可以如何实现？简单实现那还是使用 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Transform2DEffect <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>特效，在 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Win2D <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>里面可以特效套特效，此时的渲染效率依然是特别高的。在上文，咱使用缩放矩阵当成翻转矩阵，那接下来对图片的缩放就可以将缩放矩阵当成缩放矩阵了
将以上的 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>transform2DEffect <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>作为下一个 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Transform2DEffect <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>的输入源，在新的 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Transform2DEffect <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>对图片进行缩放，代码如下

最后再将 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>transform2DEffect2 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>输出到界面，代码如下

复制代码
以上代码的 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>transform2DEffect2 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>就是使用当前的 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>CanvasControl <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>的实际布局尺寸和图片的尺寸进行比例缩放，如此即可将图片拉伸填充到相同的尺寸。这一点是非常简单的，如果大家想不明白的话，试试拿出纸张和笔画一画，基础初中知识就可以理解
以上代码更多是和大家演示在 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Win2D <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>里面将两个特效进行叠加的写法。在实际应用里面，可以将上述两个 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Transform2DEffect <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>进行合并，因为这两个 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Transform2DEffect <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>都只是进行 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>TransformMatrix <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>叠加而已，可以进行更简单的数学计算。接下来部分需要用到点矩阵的知识，即上述的两个特效的叠加和对两个 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>TransformMatrix <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>矩阵进行相乘的结果是相同的。此时可以只用一个 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Transform2DEffect <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>然后将本文的两个 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Transform2DEffect <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>的 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>TransformMatrix <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>进行相乘即可，如此可以省略一次特效
尽管特效对于 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>GPU <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>来说大多都是不费资源的，对 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>Transform2DEffect <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>来说，资源使用量就更少了。但是能够通过基础 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>CPU <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>进行简单数学计算，还是能做非常多的性能提升的。这里需要额外说明的是性能是相对的，尽管说通过基础 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>CPU <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>进行简单数学计算能做非常多的性能提升，但是用人话说就是从一分钱提升到零点一分钱而已，约等于依然还是不用钱
为了更好的进行演示效果，我这里还在界面添加了一个 <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>ToggleButton <canvas:CanvasControl x:Name="Canvas" ClearColor="Black" CreateResources="Canvas_OnCreateResources" Draw="Canvas_OnDraw"/>用于点击的时候控制是否翻转，界面代码如下
