Methods

decodeAnimation(List<int> data) 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
decodeHdrImage(List<int> data, {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.
override
decodeImage(List<int> data, {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
isValidFile(List<int> data) bool
Is the given file a valid TIFF image?
override
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) TiffInfo
Validate the file is a Gif image and get information about it. If the file is not a valid Gif image, null is returned.
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.
