ImageEncoder (org.apache.xmlgraphics:xmlgraphics-commons 2.7 API)

All Known Implementing Classes:

ImageEncoderImpl, PNGImageEncoder, TIFFImageEncoder
```
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

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`encode(Raster ras, ColorModel cm)`	Encodes a Raster with a given ColorModel and writes the output to the OutputStream associated with this ImageEncoder.
`void`	`encode(RenderedImage im)`	Encodes a RenderedImage and writes the output to the OutputStream associated with this ImageEncoder.
`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
```
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
```
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
```
OutputStream getOutputStream()
```
    Returns the OutputStream associated with this ImageEncoder.
  - encode
```
void encode(Raster ras,
            ColorModel cm)
     throws IOException
```
    Encodes a Raster with a given ColorModel and writes the output to the OutputStream associated with this ImageEncoder.
    
    Throws:
    
    IOException
  - encode
```
void encode(RenderedImage im)
     throws IOException
```
    Encodes a RenderedImage and writes the output to the OutputStream associated with this ImageEncoder.
    
    Throws:
    
    IOException
