I was trying to add some content to Infragistics WPF controls and some of the images used were blurry. I have tried setting SnapToDevicePixels, but to no visible effect. I did stumble upon a property in the Infragistics.Windows.Utilities class, called SnapElementToDevicePixels. I didn't know what it does, but I tried it anyway. Voila! The image got crisp and clear.

This is the comment from the property in the Infragistics WPF sources:

/// <summary>
/// SnapElementToDevicePixels Attached Dependency Property
/// </summary>
/// <remarks>
/// <p class="body">The SnapsElementToDevicePixels is meant to be used on elements such as an Image that
/// does not currently support SnapsToDevicePixels.</p>
/// <p class="note"><b>Note:</b> The RenderTransform of the element is used so you should not set the RenderTransform
/// on the same element on which you are setting SnapElementToDevicePixels to true. You may set the RenderTransform on
/// an ancestor element. Also, you should not set this property on an element that is an ancestor of one or more
/// elements that have this property set to true. In such a case the results are undefined since the child element's
/// RenderTransform could be calculated before that of the ancestor element. Since this property should be set on
/// discrete elements such as an Image, this scenario should not be required.</p>/// </remarks>

In order to use it, make sure you load the Infragistics.Windows namespace in your XAML:


and then set the Windows:Utilities.SnapElementToDevicePixels property to True.
