Interface ImageEncoder
- All Known Implementing Classes:
- ImageEncoderImpl
- public interface ImageEncoder
An interface describing objects that transform a BufferedImage or Raster into an OutputStream.
This interface is not a committed part of the JAI API. It may be removed or changed in future releases of JAI.
| Method Summary | |
void |
encode(java.awt.image.Raster ras,
java.awt.image.ColorModel cm)
Encodes a Raster with a given ColorModel and writes the output to the OutputStream associated with this ImageEncoder. |
void |
encode(java.awt.image.RenderedImage im)
Encodes a RenderedImage and writes the output to the OutputStream associated with this ImageEncoder. |
java.io.OutputStream |
getOutputStream()
Returns the OutputStream associated with this ImageEncoder. |
ImageEncodeParam |
getParam()
Returns the current parameters as an instance of the ImageEncodeParam interface. |
void |
setParam(ImageEncodeParam param)
Sets the current parameters to an instance of the ImageEncodeParam interface. |
| 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.
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.
getOutputStream
public java.io.OutputStream getOutputStream()
- Returns the OutputStream associated with this 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.
encode
public void encode(java.awt.image.RenderedImage im) throws java.io.IOException
- Encodes a RenderedImage and writes the output to the
OutputStream associated with this ImageEncoder.
