问题

I need

XAML:

<Image Height="500"

C#:

  wbmap = new WriteableBitmap(50, 50, 500, 500, PixelFormats.Indexed8, palette);
  wbmap.WritePixels(new Int32Rect(0, 0, wbmap.PixelWidth, wbmap.PixelHeight), pixels, wbmap.PixelWidth * wbmap.Format.BitsPerPixel / 8, 0);
  image.Source = wbmap;

回答1:

As tkerwin mentioned, change the BitmapScalingMode to NearestNeighbor in you XAML Image code:

RenderOptions.BitmapScalingMode="NearestNeighbor"

回答2:

Perhaps you need to change the bitmap scaling mode to nearest neighbor.

Add RenderOptions.BitmapScalingMode="NearestNeighbor" to your Image tag.

回答3:

Increase resolution / scale without anti-aliasing.

Whats happening is WPF is scaling the image but "averaging" the pixels, rather than doing a more blocky scale.

Resize bitmap like in MS Paint
