Methods

decodeRegion(Rectangle rect, double sampleSize) → ImageWrapper

Method is used to decode rectangle region in the image specified by rect. rect area to render Rectangle sampleSize if set to a value > 1, requests the decoder to subsample the original image, returning a smaller image to save memory. Returns constructed bitmap

override

newInstance(Uint8List data) → BitmapRegionDecoder

Method is used to create instance of BitmapRegionDecoder data raw image data (could be raw svg string) Returns nstance of decoder, which could be used for decoding byte array to bitmap.

override

newInstanceFromImage(Image data) → BitmapRegionDecoder

Creates decoder from Image without copying raw bytes again. data image instance (e.g. from SDK pipeline); must remain valid while decoder is used Returns decoder instance or null on error

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.
