When should I use SnapsToDevicePixels in WPF 4.0?

Question

Can anyone suggest a guideline on when to use SnapsToDevicePixels in WPF 4.0?

Should it only be used occasionally if there is an issue, liberally throug

Answer 1

One case is if you are displaying an image or video. If you don't snap to device pixels (ie to the video screen's pixels) then some algorithm (interpolation, anti-aliasing) is used to position your image's pixels "in between" your screen's pixels, and what is displayed won't look as good as the original image would. The image would lose some sharpness.
