Invert brush

Is there an equivalent in WPF to BitBlt with DSTINVERT as the last argument?

(This inverts whatever is behind the brush)

Cheers

Sorry, there is not. Blend mode and ROP-type rendering are available if you
wish to leverage our BitmapEffects, but they are not built-in, and this will
allow you to blend between arbitrary *inputs*, though not with the back
buffer . The primary issue with ROPs as they are used in GDI is that they
implicitly require the back-buffer (as you say, "whatever is behind the
brush") to be present, while with a hierarchical retained scene graph, "what
is behind" may not exist yet, or it may be in the process of being
accumulated into a temporary buffer, etc, etc.
