Pointillism is a painting technique where the image is composed of tiny, separate dots of primary color. Non-primary colors are created by placing primary colors beside each other and allowing the "mixing" to be performed when the image is viewed.
This method supports 12- and 16-bit grayscale and 48- and 64-bit color images. Support for 12- and 16-bit grayscale and 48- and 64-bit color images is available only in the Document/Medical toolkits.
If the image has a region, this method works only on the region. If the image does not have a region, this method works on the entire image.
This method does not support signed data images.
This command does not support 32-bit grayscale images.

Run the PointillistCommand on an image.
