Encodes the supplied
Image
into a particular format and puts the result where specified or returns it as a
String.
With no arguments supplied, an
Array
of
String
values is returned that lists the recognized format names.
When no
format
is supplied, the encoding defaults to
JPEG.
A
destination
for the encoding can be a local file or a writable
URL,
namely a
CGI
script.
Alternatively, any wrtiable
Stream
can be supplied as an
output
sink.
When either a
destination
or an
output
stream is supplied, the built-in returns a non-zero value on success and zero, otherwise.
When these are not specified, the built-in returns a
String
containing the encoded image or
NULL
if the image could no be encoded.
This built-in is recommended over
encodeJPEG,
which will eventually be retired.
