The resulting color values are scaled to the precision of the destination image. Color conversion can be specified via an array of ColorSpace objects or an array of ICC_Profile objects. <p> If the source is a BufferedImage with premultiplied alpha, the color components are divided by the alpha component before color conversion. If the destination is a BufferedImage with premultiplied alpha, the color components are multiplied by the alpha component after conversion. Rasters are treated as having no alpha channel, i.e. all bands are color bands. <p> If a RenderingHints object is specified in the constructor, the color rendering hint and the dithering hint may be used to control color conversion. <p> Note that Source and Destination may be the same object. <p><P><DL><DT><B>See Also: </B><DD><A
