load method

Future load(
  1. dynamic imageFile,
  2. Size viewportSize
)

The load method loads the image asynchronously and sets the image dimensions, viewport ratio, and raw image data.

Implementation

Future load(dynamic imageFile, Size viewportSize) async {
  loader = Completer();
  dynamic decodedImage;

  if (imageFile is ImageItem) {
    height = imageFile.height;
    width = imageFile.width;

    image = imageFile.image;
    viewportRatio = imageFile.viewportRatio;

    loader.complete(true);
  } else if (imageFile is File || imageFile is XFile) {
    image = await imageFile.readAsBytes();
    decodedImage = await decodeImageFromList(image);
  } else {
    image = imageFile;
    decodedImage = await decodeImageFromList(imageFile);
  }

  if (decodedImage != null) {
    height = decodedImage.height;
    width = decodedImage.width;
    viewportRatio = viewportSize.height / height;

    loader.complete(decodedImage);
  }

  return true;
}
