Examples of ImageWriterSpi

ae.javax.imageio.spi.ImageWriterSpi
The service provider interface (SPI) for ImageWriters. For more information on service provider classes, see the class comment for the IIORegistry class.
Each ImageWriterSpi provides several types of information about the ImageWriter class with which it is associated.
The name of the vendor who defined the SPI class and a brief description of the class are available via the getVendorName, getDescription, and getVersion methods. These methods may be internationalized to provide locale-specific output. These methods are intended mainly to provide short, human-writable information that might be used to organize a pop-up menu or other list.
Lists of format names, file suffixes, and MIME types associated with the service may be obtained by means of the getFormatNames, getFileSuffixes, and getMIMEType methods. These methods may be used to identify candidate ImageWriters for writing a particular file or stream based on manual format selection, file naming, or MIME associations.
A more reliable way to determine which ImageWriters are likely to be able to parse a particular data stream is provided by the canEncodeImage method. This methods allows the service provider to inspect the actual image contents.
Finally, an instance of the ImageWriter class associated with this service provider may be obtained by calling the createWriterInstance method. Any heavyweight initialization, such as the loading of native libraries or creation of large tables, should be deferred at least until the first invocation of this method. @see IIORegistry @see ae.javax.imageio.ImageTypeSpecifier @see ae.javax.imageio.ImageWriter
