c# WinForm - SharpDX.Toolkit.Graphics绘制2D纹理

我想为一个c# WinForms应用程序实现硬件加速。原因是我必须绘制150 x 720p的图像和5 picturebox控件的时间太长(缩放+绘制图像)，因此处理和重新加载的问题。所以我处理了ShapeDX。

但是现在我卡住了，不知道如何绘制2D纹理。为了测试代码，我只需要一个测试按钮和一个PictureBox。

当我在PictureBox中运行代码时，DirectX (Draw或3D)也被加载。我承认黑色背景。但我不明白纹理必须如何绘制

        String imageFile = "Image.JPG";
        Control TargetControl = this.pictureBoxCurrentFrameL;
        int TotalWidth = TargetControl.Width;
        int TotalHeight = TargetControl.Height;
        SharpDX.Direct3D11.Device defaultDevice = new SharpDX.Direct3D11.Device(SharpDX.Direct3D.DriverType.Hardware, SharpDX.Direct3D11.DeviceCreationFlags.Debug);
        SharpDX.Toolkit.Graphics.GraphicsDevice graphicsDevice = SharpDX.Toolkit.Graphics.GraphicsDevice.New(defaultDevice);
        SharpDX.Toolkit.Graphics.PresentationParameters presentationParameters = new SharpDX.Toolkit.Graphics.PresentationParameters();
        presentationParameters.DeviceWindowHandle = this.pictureBoxCurrentFrameL.Handle;
        presentationParameters.BackBufferWidth = TotalWidth;
        presentationParameters.BackBufferHeight = TotalHeight;
        SharpDX.Toolkit.Graphics.SwapChainGraphicsPresenter swapChainGraphicsPresenter = new SharpDX.Toolkit.Graphics.SwapChainGraphicsPresenter(graphicsDevice, presentationParameters);
        SharpDX.Toolkit.Graphics.Texture2D texture2D = SharpDX.Toolkit.Graphics.Texture2D.Load(graphicsDevice, imageFile);
        //Now i should draw. But how?
        swapChainGraphicsPresenter.Present();/**/

使用Microsoft Visual Studio Community 2015Net 4, c# WinForm)和SharpDX-SDK-2.6.3!

c# WinForm - SharpDX.Toolkit.Graphics绘制2D纹理

我通过简单地切换到SlimDX (SlimDX Runtime . net 4.0 x64 2012年1月)解决了这个问题。msi， . net 4, Win10, MS Visual Studio Community 2015, Winforms App.)。有几个有用的教程。

要使用SlimDX，只需将唯一的DLL链接到您的项目!在安装了SlimDX之后，你会在你的C盘上找到这个slidx .dll文件。

重要的是要明白，你需要至少一个工厂和一个渲染目标的Direct2D。RenderTarget指向要使用的对象(控件/表单等)并接管绘图。

不需要交换链。可能由渲染目标内部使用。最大的部分是将位图转换成有用的Direct2D位图(用于绘图)。否则，您也可以从MemoryStream处理位图数据。

对于那些也在寻找解决方案的人:

        Control targetControl = this.pictureBoxCurrentFrameL;
        String imageFile = "Image.JPG";
        //Update control styles, works for forms, not for controls. I solve this later otherwise .
        //this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
        //this.SetStyle(ControlStyles.Opaque, true);
        //this.SetStyle(ControlStyles.ResizeRedraw, true);
        //Get requested debug level
        SlimDX.Direct2D.DebugLevel debugLevel = SlimDX.Direct2D.DebugLevel.None;
        //Resources for Direct2D rendering
        SlimDX.Direct2D.Factory d2dFactory = new SlimDX.Direct2D.Factory(SlimDX.Direct2D.FactoryType.Multithreaded, debugLevel);
        //Create the render target
        SlimDX.Direct2D.WindowRenderTarget d2dWindowRenderTarget = new SlimDX.Direct2D.WindowRenderTarget(d2dFactory, new SlimDX.Direct2D.WindowRenderTargetProperties() {
            Handle = targetControl.Handle,
            PixelSize = targetControl.Size,
            PresentOptions = SlimDX.Direct2D.PresentOptions.Immediately
        });
        //Paint!
        d2dWindowRenderTarget.BeginDraw();
        d2dWindowRenderTarget.Clear(new SlimDX.Color4(Color.LightSteelBlue));
        //Convert System.Drawing.Bitmap into SlimDX.Direct2D.Bitmap!
        System.Drawing.Bitmap bitmap = (System.Drawing.Bitmap)Properties.Resources.Image_720p;//loaded from embedded resource, can be changed to Bitmap.FromFile(imageFile); to load from hdd!
        SlimDX.Direct2D.Bitmap d2dBitmap = null;
        System.Drawing.Imaging.BitmapData bitmapData = bitmap.LockBits(new Rectangle(new Point(0, 0), bitmap.Size), System.Drawing.Imaging.ImageLockMode.ReadOnly, System.Drawing.Imaging.PixelFormat.Format32bppPArgb);//TODO: PixelFormat is very important!!! Check!
        SlimDX.DataStream dataStream = new SlimDX.DataStream(bitmapData.Scan0, bitmapData.Stride * bitmapData.Height, true, false);
        SlimDX.Direct2D.PixelFormat d2dPixelFormat = new SlimDX.Direct2D.PixelFormat(SlimDX.DXGI.Format.B8G8R8A8_UNorm, SlimDX.Direct2D.AlphaMode.Premultiplied);
        SlimDX.Direct2D.BitmapProperties d2dBitmapProperties = new SlimDX.Direct2D.BitmapProperties();
        d2dBitmapProperties.PixelFormat = d2dPixelFormat;
        d2dBitmap = new SlimDX.Direct2D.Bitmap(d2dWindowRenderTarget, new Size(bitmap.Width, bitmap.Height), dataStream, bitmapData.Stride, d2dBitmapProperties);
        bitmap.UnlockBits(bitmapData);
        //Draw SlimDX.Direct2D.Bitmap
        d2dWindowRenderTarget.DrawBitmap(d2dBitmap, new Rectangle(0, 0, bitmap.Width, bitmap.Height));/**/
        d2dWindowRenderTarget.EndDraw();
        //Dispose everything u dont need anymore.
        //bitmap.Dispose();//......

所以使用Direct2D非常简单，所有的代码都可以压缩到2个主线+绘图:

        SlimDX.Direct2D.Factory d2dFactory = new SlimDX.Direct2D.Factory(SlimDX.Direct2D.FactoryType.Multithreaded, SlimDX.Direct2D.DebugLevel.None);
        SlimDX.Direct2D.WindowRenderTarget d2dWindowRenderTarget = new SlimDX.Direct2D.WindowRenderTarget(d2dFactory, new SlimDX.Direct2D.WindowRenderTargetProperties() { Handle = targetControl.Handle, PixelSize = targetControl.Size, PresentOptions = SlimDX.Direct2D.PresentOptions.Immediately });
        d2dWindowRenderTarget.BeginDraw();
        d2dWindowRenderTarget.Clear(new SlimDX.Color4(Color.LightSteelBlue));
        d2dWindowRenderTarget.DrawRectangle(new SlimDX.Direct2D.SolidColorBrush(d2dWindowRenderTarget, new SlimDX.Color4(Color.Red)), new Rectangle(20,20, targetControl.Width-40, targetControl.Height-40));
        d2dWindowRenderTarget.EndDraw();
