createImageFromPDF method

@override Future<List<String>?> createImageFromPDF({ required String inputPath, required String outputPath, ImageFromPdfConfig config = const ImageFromPdfConfig(), })

Creates images from a PDF file.

This method sends a request to the native platform to extract images from the PDF file specified in the path parameter and saves the images in the outputDirPath directory.

Parameters:

• inputPath: The file path of the PDF from which images will be extracted.
• outputPath: The directory path where the images 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).
  • compression: The image compression level for the images, affecting file size, quality and clarity (default is ImageCompression.none).
  • createOneImage: Indicates whether to create a single image or separate images for each page (default is true).

Returns:

• A Future<List<String>?> representing a list of image file paths. If the operation is successful, it returns a list of file paths to the extracted images; otherwise, it returns null.

Implementation

@override
Future<List<String>?> createImageFromPDF({
  required String inputPath,
  required String outputPath,
  ImageFromPdfConfig config = const ImageFromPdfConfig(),
}) async {
  final result = await methodChannel.invokeMethod<List<dynamic>>(
    'createImageFromPDF',
    {
      'path': inputPath,
      'outputDirPath': outputPath,
      'height': config.rescale.height,
      'width': config.rescale.width,
      'compression': config.compression.value,
      'createOneImage': config.createOneImage,
    },
  );
  return result?.cast<String>();
