Dithering is not necessary for PNG-24 because pixels can be semitransparent in PNG-24 files, while they must be either fully transparent or fully opaque in GIF and PNG-8 files. To create the appearance of soft, transparent edges in GIF and PNG-8 files, specify a matte color in Photoshop or ImageReady that is the same as the background color of your web page. See Figure 10-7 for a comparison.
