处理DDS文件时位图解码器崩溃

Question

我想在朋友的计算机上测试我的应用程序，以检查我的工作是否在其他人的机器上运行。(我是否包括了所有库？等等(

但是，当我加载 *.dds 纹理时，我的应用程序崩溃了。我在场景的 2D 背景中使用它们。以下是我用来加载DDS纹理并将其转换为位图的代码：

using (SharpDX.WIC.BitmapDecoder bitmapDecoder = new SharpDX.WIC.BitmapDecoder(ImagingFactory, new MemoryStream(iconInfo.Data, false), SharpDX.WIC.DecodeOptions.CacheOnDemand))
{
    using (SharpDX.WIC.FormatConverter formatConverter = new SharpDX.WIC.FormatConverter(ImagingFactory))
    {
        formatConverter.Initialize(bitmapDecoder.GetFrame(0), SharpDX.WIC.PixelFormat.Format32bppPRGBA, SharpDX.WIC.BitmapDitherType.None, null, 0.0, SharpDX.WIC.BitmapPaletteType.Custom);
        SharpDX.DataStream dataStream = new SharpDX.DataStream(formatConverter.Size.Height * formatConverter.Size.Width * 4, true, true);
        formatConverter.CopyPixels(formatConverter.Size.Width * 4, dataStream);
        _icons.Add(iconInfo.Name, new SharpDX.Direct2D1.Bitmap(renderTarget, new SharpDX.Size2(formatConverter.Size.Width, formatConverter.Size.Height), dataStream,
            formatConverter.Size.Width * 4, bitmapProperties));
    }
}

"iconInfo.Data"是DDS纹理的数据字节。

引发的异常是

SharpDX.SharpDXException: HRESULT: [0x88982F50], Module: [SharpDX.WIC], ApiCode: [WINCODEC_ERR_COMPONENTNOTFOUND/Componentnotfound], Message: Unknown
   at SharpDX.Result.CheckError()
   at SharpDX.WIC.ImagingFactory.CreateDecoderFromStream_(IntPtr streamRef, Nullable`1 guidVendorRef, DecodeOptions metadataOptions, BitmapDecoder decoderOut)
   at SharpDX.WIC.BitmapDecoder..ctor(ImagingFactory factory, Stream streamRef, DecodeOptions metadataOptions)

您知道是什么导致了问题吗？

Answer 1

DDS文件的WIC编解码器具有许多重要的限制。首先，它仅包含在 Windows 8.1 或更高版本中。其次，它仅支持 BC1/BC2/BC3(又名 DXT1-DXT5(格式。请参阅 MSDN

一般来说，您最好使用专门的DDS纹理加载器。
