      • ImageEncoderImpl

        public ImageEncoderImpl​(java.io.OutputStream output,
                                ImageEncodeParam param)
        Constructs an ImageEncoderImpl with a given OutputStream and ImageEncoderParam instance.
    • Method Detail

      • getParam

        public ImageEncodeParam getParam()
        Returns the current parameters as an instance of the ImageEncodeParam interface. Concrete implementations of this interface will return corresponding concrete implementations of the ImageEncodeParam interface. For example, a JPEGImageEncoder will return an instance of JPEGEncodeParam.
        Specified by:
        getParam in interface ImageEncoder
      • setParam

        public void setParam​(ImageEncodeParam param)
        Sets the current parameters to an instance of the ImageEncodeParam interface. Concrete implementations of ImageEncoder may throw a RuntimeException if the params argument is not an instance of the appropriate subclass or subinterface. For example, a JPEGImageEncoder will expect param to be an instance of JPEGEncodeParam.
        Specified by:
        setParam in interface ImageEncoder
      • getOutputStream

        public java.io.OutputStream getOutputStream()
        Returns the OutputStream associated with this ImageEncoder.
        Specified by:
        getOutputStream in interface ImageEncoder
      • encode

        public void encode​(java.awt.image.Raster ras,
                           java.awt.image.ColorModel cm)
                    throws java.io.IOException
        Encodes a Raster with a given ColorModel and writes the output to the OutputStream associated with this ImageEncoder.
        Specified by:
        encode in interface ImageEncoder
        Throws:
        java.io.IOException

        Encodes a RenderedImage and writes the output to the OutputStream associated with this ImageEncoder.
        Specified by:
        encode in interface ImageEncoder
        Throws:
