Methods

acceptsInput(Uint8List encoded) → bool
Recognizes input accepted by this codec before attempting a decode.
inherited
checkDecodedDimensions(int width, int height, int maxPixels) → void
Rejects dimensions that exceed maxPixels before allocating pixels.
inherited
decode(Uint8List encoded, {WebPDecodeOptions? decodeOptions}) → Image
Decodes encoded data.
inherited
decodeBytes(Uint8List encoded, {WebPDecodeOptions? decodeOptions}) → Image
Decodes bytes after shared format and allocation-option validation.
inherited
encode(Image input, {WebPEncodeOptions? encodeOptions}) → Uint8List
Encodes input.
inherited
encodeImage(Image image, {WebPEncodeOptions? encodeOptions}) → Uint8List
Encodes an image while format-specific options are in effect.
inherited
encodeImageWith(ParallelRunner runner, Image image, {WebPEncodeOptions? encodeOptions}) → Future<Uint8List>
Encodes an image through runner while format-specific options apply.
inherited
encodeWith(ParallelRunner runner, Image input, {WebPEncodeOptions? encodeOptions}) → Future<Uint8List>
Encodes input, offering runner the parts that can run independently.
inherited
fuse<R>(Codec<Uint8List, R> other) → Codec<Image, R>
Fuses this with other.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
