C# 结合 GDI+ 和 OpenGL/DirectX
背景：我目前在我的 C# 项目中使用自定义控件（基本控件只是绘制自定义外观和感觉（使用 gdi+？））。 这些控件中的大多数都有用于不规则形状等的透明部分。
问题：我希望在一组控件上覆盖一个半透明（不规则形状）面板。 目前，我将覆盖面板剪切到涉及的控件区域。 这工作得很好，结果看起来也不错，但过程太慢了。
问题：是否有某种方式可以通过混合一点 OpenGL/DirectX 并让显卡执行所有必要的渲染而不是依赖相当慢的 CPU 来加速渲染过程？
Background: I am currently using custom controls within my C# project (basic controls just drawing a custom look and feel (using gdi+?)). The majoritiy of these controls have transparent segments for irregular shapes etc.
Problem: I am looking to overlay a semi-transparent (irregularly shaped) panel over a group of controls. Currently I Clip the covering panel to the region of the controls involved. This works fine and the results look good, however the process is so slow.
Question: Is there some manner I can speed up the rendering process by mixing in a little OpenGL/DirectX and getting the video card to perform all the necessary rendering rather than relying on the rather slow CPU?

AFAIK 你不能真正混合 GDI+ 和 OpenGL/DX。
如果您的性能下降，并且绝对确定这是 GDI+ 的瓶颈，而不是代码的瓶颈，那么放弃 GDI+ 并用 DX 替代可能是有意义的/OGL。 （不过，您必须编写自己的控件，这将是 @$$ 中的一个主要痛苦）
或者，对于更简单的方法，请尝试 WPF/Silverlight！ 默认情况下它是可定制和可换肤的，并且基于 DX。
AFAIK you can't really mix GDI+ and OpenGL/DX.
If you're getting slow performance and are absolutely sure that it's a bottleneck in GDI+ rather than in your code, than it could make sense to ditch GDI+ and replace it with DX/OGL. (You would have to write your own controls, though, which would be a major pain in the @$$)
Or, for a simpler approach, try WPF/Silverlight! It's customizable and skinnable by default and it's based on DX.
看看 WPF 和 Silverlight。 你晚上会睡得更好。
Look at WPF and Silverlight. you would sleep better at night.
您是否尝试过在控件上打开 DoubleBuferring 以查看是否可以提高性能？

Did you try turning on DoubleBuferring on your controls to see if that gives you a performance boost?
