decodeFrame abstract method

Image? decodeFrame(
  1. int frame
)

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.

Implementation

Image? decodeFrame(int frame);
