Kinect v2 for windows：在c中調整顏色框架的大小＃

Question

任何人都知道，如果可能的話，如何降低顏色流的kinect框架分辨率？因爲全高清尺寸是太高了，我scope.Thanks 我已經找到了全高清幀此代碼：

private BitmapSource ToBitmap(ColorFrame frame) 
    { 
     int width = frame.FrameDescription.Width; 
     int height = frame.FrameDescription.Height; 
     PixelFormat format = PixelFormats.Bgr32; 

     byte[] pixels = new byte[width * height * ((PixelFormats.Bgr32.BitsPerPixel + 7)/8)]; 

     if (frame.RawColorImageFormat == ColorImageFormat.Bgra) 
     { 
      frame.CopyRawFrameDataToArray(pixels); 
     } 
     else 
     { 
      frame.CopyConvertedFrameDataToArray(pixels, ColorImageFormat.Bgra); 
     } 

     int stride = width * format.BitsPerPixel/8; 



     return BitmapSource.Create(width, height, 96, 96, format, null, pixels, stride); 


    }

我已經解決了在結尾添加該代碼

BitmapSource bitmap= BitmapSource.Create(width, height, 96, 96, format, null, pixels, stride); 
ScaleTransform scale=new ScaleTransform((Width/bitmap.PixelWidth),(Height/bitmap.PixelHeight)); 
TransformedBitmap tbBitmap = new TransformedBitmap(bitmap, scale); 

return tbBitmap; 

所以完整的方法是：

private BitmapSource ToBitmap(ColorFrame frame) 
    { 
     int width = frame.FrameDescription.Width; 
     int height = frame.FrameDescription.Height; 
     PixelFormat format = PixelFormats.Bgr32; 

     byte[] pixels = new byte[width * height * ((PixelFormats.Bgr32.BitsPerPixel + 7)/8)]; 

     if (frame.RawColorImageFormat == ColorImageFormat.Bgra) 
     { 
      frame.CopyRawFrameDataToArray(pixels); 
     } 
     else 
     { 
      frame.CopyConvertedFrameDataToArray(pixels, ColorImageFormat.Bgra); 
     } 

     int stride = width * format.BitsPerPixel/8; 
     BitmapSource bitmap= BitmapSource.Create(width, height, 96, 96, format, null, pixels, stride); 
     ScaleTransform scale=new ScaleTransform((640.0/bitmap.PixelWidth),(480.0/bitmap.PixelHeight)); 
     TransformedBitmap tbBitmap = new TransformedBitmap(bitmap, scale); 

     return tbBitmap; 
    }
