如何将 CF_DIBV5 从剪贴板 (Format17) 转换为透明位图？

GDI+ 不支持CF_DIBV5格式但是当多个应用程序将透明图像放入它们使用的剪贴板时CF_DIBV5（格式 17）保持 Alpha 通道的格式。

.NET Framework 无法处理CF_DIBV5格式，以便 .NET 应用程序无法将 Alpha 图像放入剪贴板或从剪贴板检索 Alpha 图像。

有没有c#代码支持CF_DIBV5从剪贴板到位图转换？

对不起！我正在回答我自己的问题：

[StructLayout(LayoutKind.Sequential)]
public struct BITMAPV5HEADER
{
  public uint bV5Size;
  public int bV5Width;
  public int bV5Height;
  public UInt16 bV5Planes;
  public UInt16 bV5BitCount;
  public uint bV5Compression;
  public uint bV5SizeImage;
  public int bV5XPelsPerMeter;
  public int bV5YPelsPerMeter;
  public UInt16 bV5ClrUsed;
  public UInt16 bV5ClrImportant;
  public UInt16 bV5RedMask;
  public UInt16 bV5GreenMask;
  public UInt16 bV5BlueMask;
  public UInt16 bV5AlphaMask;
  public UInt16 bV5CSType;
  public IntPtr bV5Endpoints;

  public UInt16 bV5Intent;
  public UInt16 bV5ProfileData;
  public UInt16 bV5ProfileSize;
  public UInt16 bV5Reserved;
}        
public static Bitmap CF_DIBV5ToBitmap(byte[] data)
{
    GCHandle handle = GCHandle.Alloc(data, GCHandleType.Pinned);
    var bmi = (BITMAPV5HEADER)Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(BITMAPV5HEADER));
    Bitmap bitmap = new Bitmap((int)bmi.bV5Width, (int)bmi.bV5Height, -
                               (int)(bmi.bV5SizeImage / bmi.bV5Height), PixelFormat.Format32bppArgb,
                               new IntPtr(handle.AddrOfPinnedObject().ToInt32()
                               + bmi.bV5Size + (bmi.bV5Height - 1) 
                               * (int)(bmi.bV5SizeImage / bmi.bV5Height)));
    handle.Free();
    return bitmap;
}
