Pixelate Transform

Changes an image into squares whose colors are the average of the colors of the corresponding pixels in the image. If you use one input image, the square dimension evolves from one pixel when the Progress property is 0 to MaxSquare pixels when Progress is 1. If you use two input images, the square dimension ranges from one pixel when Progress is 0 to MaxSquare pixels when Progress is 0.5, while averaging the pixels of the first image, and from MaxSquare pixels back to one pixel when Progress is 1, while averaging the pixels of the second image.

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.
