Dithering is the most common means of reducing the color range of images down to the 256 (or fewer) colors seen in 8-bit GIF images. Dithering is the process of juxtaposing pixels of two colors to create the illusion that a third color is present.
What is the difference between dithered and non dithered GIF?
No Transparency Dither applies no dither to partially transparent pixels in the image. DiffusionTransparency Dither applies a random pattern that is usually less noticeable than Pattern dither. The dither effects are diffused across adjacent pixels.
