Methods

decodeAnimation(List<int> bytes) → Animation?

Decode all of the frames from an animation. If the file is not an animation, a single frame animation is returned. If there was a problem decoding the file, null is returned.

override

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.

override

decodeHdrFrame(int frame) → HdrImage?

Decode a single high dynamic range (HDR) frame from the data that was set with startDecode. If the format of the file does not support HDR images, the regular image will be converted to an HDR image as (color / 255). 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.

inherited

decodeHdrImage(List<int> bytes, {int frame = 0}) → HdrImage?

Decode the file and extract a single High Dynamic Range (HDR) image from it. HDR images are stored in floating-poing values. If the format of the file does not support HDR images, the regular image will be converted to an HDR image as (color / 255). If the file is animated, the specified frame will be decoded. If there was a problem decoding the file, null is returned.

inherited

decodeImage(List<int> bytes, {int frame = 0}) → 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.

override

decodePsd(List<int> bytes) → PsdImage?

Decode a raw PSD image without rendering it to a flat image.

isValidFile(List<int> 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(List<int> 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.

Operators

operator ==(Object other) → bool

The equality operator.
