Method Details
-
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
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
Returns the OutputStream associated with this ImageEncoder.- Specified by:
getOutputStream
in interfaceImageEncoder
