L_INT LBitmap::Pointillist(uSize, crColor, uFlags)
Converts image colors into randomly placed dots to create a Pointillist painting, and uses the background color to fill the area between dots.
Dot size, in pixels.
Flags that indicate which background and dot type to use. You can use a bit wise OR ( | ) to specify one flag from each group.
|POINTILLIST_IMAGE||[0x0001] Use the image as the background.|
|POINTILLIST_COLOR||[0x0002] Fill the background with crColor.|
|POINTILLIST_STICKER||[0x0010] Use Dots that will overlap like stickers.|
|POINTILLIST_POINT||[0x0020] Use Dots that will adjust like bubbles.|
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
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.
Use the LBitmap::RomanMosaic function to divide the bitmap into rectangular or arc-shaped cells and then fill each cell with a color chosen randomly from the colors of each tiles pixels.
Use the LBitmap::Mosaic function to impose a mosaic effect on a bitmap by dividing the bitmap into tiles of a specified size and changing the color of all pixels in each tile to the average color of pixels within the tile.
Use the LBitmap::Pixelate function to divide the bitmap into rectangular or arc-shaped cells and then recreate the image by filling those cells with the minimum, maximum, or average pixel value, depending upon the effect that was selected.
Use the LBitmap::MosaicTiles function to make an image look like a mosaic made from tiles. Tiles can be rectangular or arc-shaped, depending upon the coordinate system used to draw the tiles.

This function 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 bitmap has a region, this function works only on the region. If the bitmap does not have a region, this function works on the entire bitmap.
This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.
This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
