split static method

Implementation

  final image = imglib.decodeImage(params.input);

  var x = 0, y = 0;
  final width = (image!.width / params.size).round();
  final height = (image.height / params.size).round();

  // split image to parts
  final parts = <imglib.Image>[];
  for (var i = 0; i < params.size; i++) {
    for (var j = 0; j < params.size; j++) {
      parts.add(imglib.copyCrop(image, x, y, width, height));
      x += width;
    }
    x = 0;
    y += height;
  }

  // convert image from image package to Image Widget to display
  final output = <Uint8List>[];
