Implementation

@override
Future<PdfAnnotationResult> openPDF({
  required String filePath,
  String? savePath,
  PDFAnnotationConfig? config,
}) async {
  final resolvedSavePath = savePath ?? _tempSavePath();

  try {
    File(resolvedSavePath).parent.createSync(recursive: true);
  } catch (e) {
    return PdfAnnotationResult.error(
        'Cannot create save directory: $e');
  }

  final args = <String, dynamic>{
    'filePath': filePath,
    'savePath': resolvedSavePath,
    ...?config?.toMap(),
  };

  final tempImagePaths = <String>[];
  if (config?.imagesToInsert != null && config!.imagesToInsert!.isNotEmpty) {
    try {
      tempImagePaths.addAll(await _saveImagesToTemp(config.imagesToInsert!));
    } catch (e) {
      return PdfAnnotationResult.error('Failed to prepare images: $e');
    }
    if (tempImagePaths.isNotEmpty) args['imagePaths'] = tempImagePaths;
  }

  try {
    return await _invoke(args);
  } finally {
    _cleanupTempImages(tempImagePaths);
  }
