XAML：
<Image Height="500"
MouseLeftButtonDown="image_MouseLeftButtonDown"
MouseRightButtonDown="image_MouseRightButtonDown"
Name="image"
Stretch="Fill"
Width="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;

正如 tkerwin 提到的，将 BitmapScalingMode 更改为 < XAML 图像代码中的 code>NearestNeighbor ：
As tkerwin mentioned, change the BitmapScalingMode to
NearestNeighborin you XAML Image code:也许您需要将位图缩放模式更改为最近邻居。
将
RenderOptions.BitmapScalingMode="NearestNeighbor"添加到您的 Image 标记中。Perhaps you need to change the bitmap scaling mode to nearest neighbor.
Add
RenderOptions.BitmapScalingMode="NearestNeighbor"to your Image tag.提高分辨率/比例而不进行抗锯齿。
发生的情况是 WPF 正在缩放图像，但“平均”像素，而不是进行更块状的缩放。
请参阅这篇文章：
像在 MS Paint 中一样调整位图大小
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.
