WebStandard ordered dithering, which uses the Bayer threshold matrix, is: Threshold =COLOR(256/4,256/4,256/4);/* Estimated precision of the palette */ For each pixel,Input,in the original picture: Factor =ThresholdMatrix[xcoordinate %X][ycoordinate %Y]; Attempt =Input +Factor *Threshold Color =FindClosestColorFrom(Palette,Attempt) WebOrdered dithering is an image dithering algorithm. It is commonly used by programs that need to provide continuous image of higher colors on a display of less color depth. For example, Microsoft Windows uses it in 16-color graphics modes. It is easily distinguished by its noticeable crosshatch patterns. order double glazed windows online
