Zigzag Transform

Changes one image into another in a zigzag pattern. The output image is divided into a grid. The cells in the grid change from the first image to the second image in a zigzag order. The zigzag pattern starts in the upper-left corner and moves in the following order: first row, left to right; second row, right to left; third row, left to right again; and so on.

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.
