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

com.sun.image.codec.jpeg.JPEGImageDecoder
This interface describes a JPEG data stream decoder. This decoder takes an InputStream that contains JPEG encoded image data. The JPEGImageDecoder will decode the JPEG image data according to the parameters set in a JPEGDecodeParam object. The resulting image data is returned in either a Raster or a BufferedImage.
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.
