CDXBaseNTo1::DoDither Method

This topic documents a feature of Visual Filters and Transitions, which is deprecated as of Windows Internet Explorer 9 and obsolete as of Internet Explorer 10.

Determines whether the transform output should be dithered.


BOOL DoDither(VOID) const;

Return Value

Returns a Boolean value indicating whether to dither the output. If TRUE, the transform should dither its result to the output surface. If FALSE, it should write the new values unmodified.


Transforms are expected to implement dithering in their output. This significantly improves the quality of results when rendering the output to low color-precision surfaces.
