C#WinForm-SharpDX.Toolkit.Graphics绘制二维纹理
我想为C#WinForms应用程序实现硬件加速。原因是我必须绘制150 x 720p的图像，而5个picturebox控件花费的时间太长（缩放+图像绘制），因此存在处理和重新加载问题。 所以我处理了ShapeDX 但是现在我被卡住了，不知道如何绘制2D纹理。为了测试代码，我只有一个测试按钮和一个图片盒 当我在PictureBox中运行代码时，也会加载DirectX（Draw或3D）。我承认黑色背景但我不明白纹理必须如何绘制。C#WinForm-SharpDX.Toolkit.Graphics绘制二维纹理,c#,winforms,sharpdx,slimdx,C#,Winforms,Sharpdx,Slimdx,我想为C#WinForms应用程序实现硬件加速。原因是我必须绘制150 x 720p的图像，而5个picturebox控件花费的时间太长（缩放+图像绘制），因此存在处理和重新加载问题。 所以我处理了ShapeDX 但是现在我被卡住了，不知道如何绘制2D纹理。为了测试代码，我只有一个测试按钮和一个图片盒 当我在PictureBox中运行代码时，也会加载DirectX（Draw或3D）。我承认黑色背景但我不明白纹理必须如何绘制。 String imageFile = "Image.J

感谢您的帮助。我只需切换到SlimDX（SlimDX运行时.NET 4.0 x64 2012年1月.msi、.Net4、Win10、MS Visual Studio Community 2015、Winforms App.）即可解决问题。有几个有用的教程 要使用SlimDX，只需将唯一一个DLL链接到您的项目！安装SlimDX后，您将在您的C驱动器的某处找到此SlimDX.dll文件 必须了解Direct2D至少需要一个工厂和一个渲染目标。RenderTarget指向要使用的对象（Control/form/etc）并接管图形 不需要交换链。可能由渲染目标在内部使用。最大的部分是将位图转换为有用的Direct2D位图（用于绘图）。否则，您也可以从MemoryStream处理位图数据 对于那些正在寻找解决方案的人：

您需要多久更新一次UI？每秒多少次？你可能只需要使用GDI，我每秒可以获得150x720p的帧数。是5倍不同的震源（30 fps）。2x 720p视频（30 fps）2x 720p视频帧（具有已识别的模式）1x 720p视频帧（具有最终结果模式识别）分为多个线程。最终计算也在单独的螺纹上执行。所有图像都是从不同的线程生成的，并且是异步的。显然，性能与控制类似。我认为使用GDI比使用控件更好。因此，您可以控制绘图（例如放置框架、处置等），但我更喜欢使用直接绘图。有人能帮我解决直接绘图问题吗？有人知道吗？如果你只画2D的东西，你应该使用Direct2D。我很确定SharpDX已经包装好了。DirectDraw已被标记为不推荐使用大约十年了。你使用它的方式与我过去的做法不同。而且它的实现并不简单，所以我不知道在这里包含所有代码是否合适。我看看能不能把东西拼起来，但可能需要一段时间。应该有一个带有SharpDX的Direct2D示例。尝试一下，然后让我知道你是否需要帮助。你需要多久更新一次你的用户界面？每秒多少次？你可能只想使用
