SharpDx에서 png로 저장

Question

Direct2D에서 SharpDx로 Metro 응용 프로그램을 개발합니다. 나는 deviceContext을 사용하여 약간의 그림을 그렸다. 어떻게 사진을 png 파일로 저장할 수 있습니까?

솔루션 :

public class Direct2DImageEncoder 
    { 
    private readonly Direct2DFactoryManager factoryManager; 
    private readonly Bitmap wicBitmap; 
    private readonly WicRenderTarget renderTarget; 

    private readonly int imageWidth, imageHeight; 

    public Direct2DImageEncoder(int imageWidth, int imageHeight, int imageDpi) 
    { 
     this.imageWidth = imageWidth; 
     this.imageHeight = imageHeight;  

     factoryManager = new Direct2DFactoryManager(); 

     wicBitmap = new Bitmap(factoryManager.WicFactory, imageWidth, imageHeight, SharpDX.WIC.PixelFormat.Format32bppBGR, BitmapCreateCacheOption.CacheOnLoad); 
     var renderTargetProperties = new RenderTargetProperties(RenderTargetType.Default, new PixelFormat(Format.Unknown, AlphaMode.Unknown), imageDpi, imageDpi, RenderTargetUsage.None, FeatureLevel.Level_DEFAULT); 
     renderTarget = new WicRenderTarget(factoryManager.D2DFactory, wicBitmap, renderTargetProperties); 
     renderTarget.BeginDraw(); 
     renderTarget.Clear(Colors.White); 
    } 

    public void Save(Stream systemStream, Direct2DImageFormat format) 
    { 
     renderTarget.EndDraw(); 

     var stream = new WICStream(factoryManager.WicFactory, systemStream); 
     var encoder = new BitmapEncoder(factoryManager.WicFactory, Direct2DConverter.ConvertImageFormat(format)); 
     encoder.Initialize(stream); 

     var bitmapFrameEncode = new BitmapFrameEncode(encoder); 
     bitmapFrameEncode.Initialize(); 
     bitmapFrameEncode.SetSize(imageWidth, imageHeight); 
     bitmapFrameEncode.PixelFormat = SharpDX.WIC.PixelFormat.FormatDontCare; 
     bitmapFrameEncode.WriteSource(wicBitmap); 

     bitmapFrameEncode.Commit(); 
     encoder.Commit(); 

     bitmapFrameEncode.Dispose(); 
     encoder.Dispose(); 
     stream.Dispose();  
    } 
    } 

    public class Direct2DFactoryManager 
    { 
    private readonly SharpDX.WIC.ImagingFactory wicFactory; 
    private readonly SharpDX.Direct2D1.Factory d2DFactory; 
    private readonly SharpDX.DirectWrite.Factory dwFactory; 

    public Direct2DFactoryManager() 
    { 
     wicFactory = new SharpDX.WIC.ImagingFactory(); 
     d2DFactory = new SharpDX.Direct2D1.Factory(); 
     dwFactory = new SharpDX.DirectWrite.Factory(); 
    } 

    public SharpDX.WIC.ImagingFactory WicFactory 
    { 
     get 
     { 
     return wicFactory; 
     } 
    } 

    public SharpDX.Direct2D1.Factory D2DFactory 
    { 
     get 
     { 
     return d2DFactory; 
     } 
    } 

    public SharpDX.DirectWrite.Factory DwFactory 
    { 
     get 
     { 
     return dwFactory; 
     } 
    } 
    } 

    public enum Direct2DImageFormat 
    { 
    Png, Gif, Ico, Jpeg, Wmp, Tiff, Bmp 
    } 

    public class Direct2DConverter 
    { 
    public static Guid ConvertImageFormat(Direct2DImageFormat format) 
    { 
     switch (format) 
     { 
     case Direct2DImageFormat.Bmp: 
      return ContainerFormatGuids.Bmp; 
     case Direct2DImageFormat.Ico: 
      return ContainerFormatGuids.Ico; 
     case Direct2DImageFormat.Gif: 
      return ContainerFormatGuids.Gif; 
     case Direct2DImageFormat.Jpeg: 
      return ContainerFormatGuids.Jpeg; 
     case Direct2DImageFormat.Png: 
      return ContainerFormatGuids.Png; 
     case Direct2DImageFormat.Tiff: 
      return ContainerFormatGuids.Tiff; 
     case Direct2DImageFormat.Wmp: 
      return ContainerFormatGuids.Wmp; 
     } 
     throw new NotSupportedException(); 
    } 

    #endregion 
    }
