Constructor Details

PICTImageWriter

public PICTImageWriter()

PICTImageWriter

protected PICTImageWriter(ImageWriterSpi pProvider)

Constructs an ImageWriter and sets its originatingProvider instance variable to the supplied value.

Subclasses that make use of extensions should provide a constructor with signature (ImageWriterSpi, Object) in order to retrieve the extension object. If the extension object is unsuitable, an IllegalArgumentException should be thrown.

Parameters:

pProvider - the ImageWriterSpi that is constructing this object, or null.
