RadialWipe Transform

Generates a radial wipe (a wipe of the second image over the first that sweeps radially) of a specified type. The CRRWS_CLOCK and CRRWS_WEDGE radial wipe types start at 12 o'clock and are centered on the image. CRRWS_CLOCK sweeps the second image clockwise over the first image. CRRWS_WEDGE sweeps the second image simultaneously clockwise and counterclockwise from 12 o'clock over the first image. The CRRWS_RADIAL wipe starts with its center in the upper-left corner of the image and sweeps down from the top in a radial arc.

Note To use this transform, you need to have Microsoft® DirectX® Media 6, Microsoft Internet Explorer 5, Microsoft Windows® 98 Second Edition, or Windows 2000 installed.
