问题描述
你好, 我想制作一个实时否定过滤器. (就像放大镜一样,但是应用负滤镜而不是缩放) 我现在所能做的就是使表格透明. 我已经在Window.Background上尝试过位图效果,但是它不起作用. 有什么办法可以反转所选区域的颜色吗? 谢谢.
解决方案要创建否定过滤器,您可以选中文章 [ ^ ]. 进行类似于放大镜应用程序的应用程序需要捕获屏幕(搜索代码项目,其中有很多),并确定要过滤的区域(最终将其渲染到某个地方).
Hello, I want to make a real-time negative filter. (Just like magnifier but apply negative filter instead of zooming) All I can do now is making the form transparent. I have tried Bitmap Effect on Window.Background but it''s not working. Is there any way to invert the color of the selected region ? Thank you.
解决方案 In order to create a negative filter you can check this article[^]. Making an appliation that works like the magnifier appliction involves captring the screen (search codeproject, it has plenty of those), and deciding on which area sould be filtered (and eventualy render it somewhere).更多推荐
