Methods

decode(Uint8List bytes, {int? frame}) → Image?

Decode the file and extract a single image from it. If the file is animated, and frame is specified, that particular frame will be decoded. Otherwise if the image is animated and frame is null, the returned Image will include all frames. If there was a problem decoding the Image, null will be returned.

override

decodeFrame(int frame) → Image?

Decode a single frame from the data that was set with startDecode. If frame is out of the range of available frames, null is returned. Non animated image files will only have frame 0. An Image is returned, which provides the image, and top-left coordinates of the image, as animated frames may only occupy a subset of the canvas.

override

isValidFile(Uint8List bytes) → bool

A light-weight function to test if the given file is able to be decoded by this Decoder.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

numFrames() → int

How many frames are available to be decoded. startDecode should have been called first. Non animated image files will have a single frame.

override

startDecode(Uint8List bytes) → DecodeInfo?

Start decoding the data as an animation sequence, but don't actually process the frames until they are requested with decodeFrame.

override

toString() → String

A string representation of this object.
