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 interfaceImageEncoder
-
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 interfaceImageEncoder
-
getOutputStream
public java.io.OutputStream getOutputStream()
Returns the OutputStream associated with this ImageEncoder.- Specified by:
getOutputStream
in interfaceImageEncoder
-
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 interfaceImageEncoder
- Throws:
java.io.IOException
-
encode
public abstract 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.- Specified by:
encode
in interfaceImageEncoder
- Throws:
java.io.IOException
