Converting images to grey scale is a nice trick to bring elements to user attention by “turning off” other elements. You could use a trick like this to “activate” or “deactivate” an element. Anyways, here is how you change an image to grey scale in WPF:
img.Source =
new FormatConvertedBitmap(
(BitmapSource)img.Source,
PixelFormats.Gray16,
BitmapPalettes.Gray16, 0
);
Hope it helps !
