createPDFFromMultipleImages method

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

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 objects representing the images 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 = inputs.map((input) => input.path).toList();
  final result = await methodChannel.invokeMethod<String>(
    'createPDFFromMultipleImage',
    {
      'paths': inputPaths,
      'outputDirPath': outputPath,
      'height': config.rescale.height,
      'width': config.rescale.width,
      'keepAspectRatio': config.keepAspectRatio,
    },
  );
  return result;
