)

The global applyfilter function

Implementation

List<int>? applyFilter(Map<String, dynamic> params) {
  Filter? filter = params["filter"];
  imageLib.Image image = params["image"];
  String filename = params["filename"];
  List<int> _bytes = image.getBytes();
  if (filter != null) {
    filter.apply(_bytes as dynamic, image.width, image.height);
  }
  imageLib.Image _image =
      imageLib.Image.fromBytes(image.width, image.height, _bytes);
  _bytes = imageLib.encodeNamedImage(_image, filename)!;

  return _bytes;
