Examples of com.sun.image.codec.jpeg.JPEGImageEncoder

com.sun.image.codec.jpeg.JPEGImageEncoder
JPEGImageEncoder encodes buffers of image data into JPEG data streams. Users of this interface are required to provide image data in a Raster or a BufferedImage, set the necessary parameters in the JPEGEncodeParams object and successfully open the OutputStream that is the destination of the encoded JPEG stream. The JPEGImageEncoder interface can encode image data into interchange, and abbreviated JPEG data streams that are written to the OutputStream provided to the encoder.
Note that the classes in the com.sun.image.codec.jpeg package are not part of the core Java APIs. They are a part of Sun's JDK and JRE distributions. Although other licensees may choose to distribute these classes, developers cannot depend on their availability in non-Sun implementations. We expect that equivalent functionality will eventually be available in a core API or standard extension.
