Examples of ColorConvertOp

ae.java.awt.image.ColorConvertOp
This class performs a pixel-by-pixel color conversion of the data in the source image. 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.
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.
If a RenderingHints object is specified in the constructor, the color rendering hint and the dithering hint may be used to control color conversion.
Note that Source and Destination may be the same object.
