Methods
-
decode(Uint8List data, {int? frame})
→ Image?
-
Decode the file and extract a single image from it. If the file is
animated, the specified
frame will be decoded. If there was a problem
decoding the file, null is returned.
inherited
-
decodeFrame(int frame)
→ Image
-
Decode a single frame from the data stat 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 AnimationFrame
is returned, which provides the image, and top-left coordinates of the
image, as animated frames may only occupy a subset of the canvas.

numFrames()
→ int

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