SharpDX.Direct2D1.位图处理在windows 8上崩溃

本文关键字：崩溃 windows Direct2D1 位图 处理 SharpDX | 更新日期: 2023-09-27 18:26:22

在应用程序完成处理几个SharpDx位图时，我遇到了一个奇怪的崩溃。该异常似乎是不可弥补的，并一直导致IIS崩溃。它并不是每次都会发生，也根本不会在windows7上发生。

使用DebugDiag生成崩溃报告：

有人能理解这次撞车事故吗？或者有人对我如何解决这个问题有什么建议吗？

SharpDX.Direct2D1.位图处理在windows 8上崩溃

终于有机会尝试@osexpert的建议。

我添加了一个新的类来存储流和使用流的各种类（WIC.BitmapDecoder、WIC.BitmapFrameDecode、WIC.FormatConverter），这样当程序完成位图时，它们可以按正确的顺序处理。

这已阻止错误出现。不幸的是，我仍然不知道为什么它只发生在Win8上。由于错误发生在某种程度上是随机的，因此Win7上的时间可能不同，因此错误没有发生。

我已经用你的建议解决了这个问题。这是我的旧代码，当我随机处理它时，它会崩溃。

internal class Direct2DTexture2D : ITexture2D, ID2DResource
{
    internal SharpDX.Direct2D1.Bitmap Texture2D;
    internal Direct2DTexture2D(IRenderTarget InRenderTarget, Bitmap InBitmap)
    {
        Direct2DResourceManager.OnResourceCreate(this);
        Direct2DRenderTarget RT = InRenderTarget as Direct2DRenderTarget;
        Texture2D = CreateFromBitmap(RT.RenderTarget, InBitmap);
    }
    internal Direct2DTexture2D(IRenderTarget InRenderTarget, string InFilePath)
    {
        Direct2DResourceManager.OnResourceCreate(this);
        Direct2DRenderTarget RT = InRenderTarget as Direct2DRenderTarget;
        var bitmap = (System.Drawing.Bitmap)System.Drawing.Image.FromFile(InFilePath);
        Texture2D = CreateFromBitmap(RT.RenderTarget, bitmap);
    }
    private SharpDX.Direct2D1.Bitmap CreateFromBitmap(SharpDX.Direct2D1.RenderTarget InRenderTarget, Bitmap InBitmap)
    {
        using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
        {
            InBitmap.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
            using (SharpDX.WIC.BitmapDecoder bitDecorder =
                new SharpDX.WIC.BitmapDecoder(Direct2DDrawingSystem.instance.ImagingFactory,
                ms,
                SharpDX.WIC.DecodeOptions.CacheOnDemand)
                )
            {
                using (SharpDX.WIC.BitmapFrameDecode bfDecode = bitDecorder.GetFrame(0))
                {
                    using (SharpDX.WIC.FormatConverter fConverter = new SharpDX.WIC.FormatConverter(Direct2DDrawingSystem.instance.ImagingFactory))
                    {
                        fConverter.Initialize(bfDecode, SharpDX.WIC.PixelFormat.Format32bppPBGRA, SharpDX.WIC.BitmapDitherType.None, null, 0, SharpDX.WIC.BitmapPaletteType.Custom);
                        return SharpDX.Direct2D1.Bitmap.FromWicBitmap(InRenderTarget, fConverter);
                    }
                }
            }
        }
    }
    public float width { get { return Texture2D.Size.Width; } }
    public float height { get { return Texture2D.Size.Height; } }
    public void Dispose()
    {
        Direct2DResourceManager.OnResourceDestroy(this);
        if (Texture2D!=null)
        {
            Texture2D.Dispose();
            Texture2D = null;
        }            
    }
}

此代码在代码周围使用using命令。下划线代码在所有平台上都能很好地工作，你可以看到：

    private System.IO.MemoryStream MemStream;

    internal SharpDX.Direct2D1.Bitmap Texture2D;
    internal Direct2DTexture2D(IRenderTarget InRenderTarget, Bitmap InBitmap)
    {
        Direct2DResourceManager.OnResourceCreate(this);
        Direct2DRenderTarget RT = InRenderTarget as Direct2DRenderTarget;
        CreateFromBitmap(RT.RenderTarget, InBitmap);
    }
    internal Direct2DTexture2D(IRenderTarget InRenderTarget, string InFilePath)
    {
        Direct2DResourceManager.OnResourceCreate(this);
        Direct2DRenderTarget RT = InRenderTarget as Direct2DRenderTarget;
        var bitmap = (System.Drawing.Bitmap)System.Drawing.Image.FromFile(InFilePath);
        CreateFromBitmap(RT.RenderTarget, bitmap);
    }
    private void CreateFromBitmap(SharpDX.Direct2D1.RenderTarget InRenderTarget, Bitmap InBitmap)
    {
        MemStream = new System.IO.MemoryStream();
        InBitmap.Save(MemStream, System.Drawing.Imaging.ImageFormat.Png);
        BitDecorder = new SharpDX.WIC.BitmapDecoder(Direct2DDrawingSystem.instance.ImagingFactory,
                            MemStream,
                            SharpDX.WIC.DecodeOptions.CacheOnDemand);
        BFDecorde = BitDecorder.GetFrame(0);
        fConverter = new SharpDX.WIC.FormatConverter(Direct2DDrawingSystem.instance.ImagingFactory);
        fConverter.Initialize(BFDecorde, SharpDX.WIC.PixelFormat.Format32bppPBGRA, SharpDX.WIC.BitmapDitherType.None, null, 0, SharpDX.WIC.BitmapPaletteType.Custom);
        Texture2D = SharpDX.Direct2D1.Bitmap.FromWicBitmap(InRenderTarget, fConverter);
    }
    public float width { get { return Texture2D.Size.Width; } }
    public float height { get { return Texture2D.Size.Height; } }
    public void Dispose()
    {
        Direct2DResourceManager.OnResourceDestroy(this);
        if (Texture2D!=null)
        {
            Texture2D.Dispose();
            Texture2D = null;
        }            
        if(fConverter!=null)
        {
            fConverter.Dispose();
            fConverter = null;
        }
        if(BFDecorde != null)
        {
            BFDecorde.Dispose();
            BFDecorde = null;
        }
        if(BitDecorder!=null)
        {
            BitDecorder.Dispose();
            BitDecorder = null;
        }
        if(MemStream!=null)
        {
            MemStream.Dispose();
            MemStream = null;
        }
    }
}

这段代码展示了如何通过sharpdx从C#位图创建direct2d图像。
