normalizeFile method

Future<NormalizedImage?> normalizeFile(String file, dynamic points, ColorMode color)

Normalize documents. file - path to the file. points - points of the document. Returns a NormalizedImage.

Implementation

Future<NormalizedImage?> normalizeFile(
    String file, dynamic points, ColorMode color) async {
  List<dynamic> jsOffsets = points.map((Offset offset) {
    return {'x': offset.dx, 'y': offset.dy};
  }).toList();

  NormalizedImage? image;
  if (_cvr != null) {
    try {
      dynamic rawSettings = await handleThenable(
          _cvr!.getSimplifiedSettings("NormalizeDocument_Default"));
      dynamic params = dartify(rawSettings);
      params['roi']['points'] = jsOffsets;
      params['roiMeasuredInPercentage'] = 0;
      params['documentSettings']['colourMode'] = color.index;
      await handleThenable(
          _cvr!.updateSettings("NormalizeDocument_Default", jsify(params)));
    } catch (e) {
      return image;
    }

    NormalizedResult normalizedResult =
        await handleThenable(_cvr!.capture(file, "NormalizeDocument_Default"))
            as NormalizedResult;

    image = _createNormalizedImage(normalizedResult);
  }

  return image;
