createPDFFromMultipleImages method

  1. @override
Future<String> createPDFFromMultipleImages({
  1. required List<MergeInput> inputs,
  2. required String outputPath,
  3. PdfFromMultipleImageConfig config = const PdfFromMultipleImageConfig(),
})
override

Creates a PDF from multiple image files.

This method sends a request to the native platform to create a PDF from the images specified in the inputs parameter. The resulting PDF is saved in the outputPath directory.

Parameters:

  • inputs: A list of MergeInput to be converted into a PDF.
  • outputPath: The directory path where the created PDF should be saved.
  • config: A configuration object that specifies how to process the images.
    • rescale: The scaling configuration for the images (default is the original image).
    • keepAspectRatio: Indicates whether to maintain the aspect ratio of the images (default is true).

Returns:

  • A Future<String?> representing the result of the operation. If the operation is successful, it returns a string message from the native platform; otherwise, it returns null.

Implementation

@override
Future<String> createPDFFromMultipleImages({
  required List<MergeInput> inputs,
  required String outputPath,
  PdfFromMultipleImageConfig config = const PdfFromMultipleImageConfig(),
}) async {
  final inputPaths = await Future.wait(inputs.map(
      (MergeInput input) async => await DocumentUtils.prepareInput(input)));
  final JSArray<JSString> jsInputPaths = inputPaths.toJSArray();
  final JSString result =
      (await createPdfFromImages(jsInputPaths, config.toMap().jsify()).toDart)
          as JSString;
  return result.toDart;
