Fields Summary
public static final Class[]	STANDARD_OUTPUT_TYPE The STANDARD_OUTPUT_TYPE contains ImageInputStream.class.
protected Class[]	outputTypes The output types.
protected String[]	readerSpiNames The reader SPI names.

Constructors Summary
protected ImageWriterSpi() Instantiates a new ImageWriterSpi. throw new UnsupportedOperationException("Not supported yet");

Methods Summary
public abstract boolean	canEncodeImage(javax.imageio.ImageTypeSpecifier type) Checks whether or not the ImageWriter implementation associated with this service provider can encode an image with the specified type. param type the ImageTypeSpecifier. return true, if an image with the specified type can be encoded, false otherwise.
public boolean	canEncodeImage(java.awt.image.RenderedImage im) Checks whether or not the ImageWriter implementation associated with this service provider can encode the specified RenderedImage. param im the RenderedImage. return true, if RenderedImage can be encoded, false otherwise. return canEncodeImage(ImageTypeSpecifier.createFromRenderedImage(im));
public javax.imageio.ImageWriter	createWriterInstance() Returns an instance of the ImageWriter implementation for this service provider. return the ImageWriter. throws IOException if an I/O exception has occurred. return createWriterInstance(null);
public abstract javax.imageio.ImageWriter	createWriterInstance(java.lang.Object extension) Returns an instance of the ImageWriter implementation for this service provider. param extension the a plug-in specific extension object, or null. return the ImageWriter. throws IOException if an I/O exception has occurred.
public java.lang.String[]	getImageReaderSpiNames() Gets an array of strings with names of the ImageReaderSpi classes that support the internal metadata representation used by the ImageWriter of this service provider, or null if there are no such ImageReaders. return the array of strings with names of the ImageWriterSpi classes. return readerSpiNames;
public java.lang.Class[]	getOutputTypes() Gets an array of Class objects whose types can be used as output for this writer. return the output types. return outputTypes;
public boolean	isFormatLossless() Returns true if the format of the writer's output is lossless. The default implementation returns true. return true, if a format is lossless, false otherwise. return true;
public boolean	isOwnWriter(javax.imageio.ImageWriter writer) Checks whether or not the specified ImageWriter object is an instance of the ImageWriter associated with this service provider or not. param writer the ImageWriter. return true, if the specified ImageWriter object is an instance of the ImageWriter associated with this service provider, false otherwise. throw new UnsupportedOperationException("Not supported yet");
