Examples of com.sun.image.codec.jpeg.JPEGImageEncoder.encode()

com.sun.image.codec.jpeg.JPEGImageEncoder.encode()
Encode a BufferedImage as a JPEG data stream. Note, some color conversions may takes place. The current JPEGEncodeParam's encoded COLOR_ID should match the value returned by getDefaultColorID when given the BufferedImage's ColorModel.
If no JPEGEncodeParam object has been provided yet a default one will be created by calling getDefaultJPEGEncodeParam with bi. @param bi The BufferedImage to encode.

  JPEGEncodeParam j2dEP = convertToJ2DJPEGEncodeParam(paramList, sm) ;
        ((JPEGParam)j2dEP).setWidth(ras.getWidth()) ; 
  ((JPEGParam)j2dEP).setHeight(ras.getHeight()) ;


  JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(baos, j2dEP) ;
  encoder.encode(ras) ;


  byte[] data = baos.toByteArray() ;


  ObjectOutputStream oos = new ObjectOutputStream(outputStream) ;
  oos.writeFloat(paramList.getFloatParameter("quality"));
