renderPdfPage method

@override Future<Uint8List?> renderPdfPage({ required int pdf, required int page, int? x, int? y, int? width, int? height, double? scale, Color background = const Color(0xFFFFFFFF), })

Converts a given page from a given pdf to a bitmap.

Optionally crop the output image to a given x and y coordinate with a given width, height.

With the scale argument you can control the output resolution. Default scale is 1 which means that the output image has exactly the size of the PDF.

Optionally set the background color which will be used instead of transparency.

Implementation

@override
Future<Uint8List?> renderPdfPage({
  required int pdf,
  required int page,
  int? x,
  int? y,
  int? width,
  int? height,
  double? scale,
  Color background = const Color(0xFFFFFFFF),
}) async {
  PdfImageRendererPageSize size;

  if (width == null || height == null) {
    size = await getPdfPageSize(pdf: pdf, page: page);

    width ??= size.width;
    height ??= size.height;
  }

  final image = await methodChannel.invokeMethod<Uint8List>('renderPDFPage', {
    'pdf': pdf,
    'page': page,
    'x': x,
    'y': y,
    'width': width,
    'height': height,
    'scale': scale,
    'background': '#${background.value.toRadixString(16)}',
  });
  return image;
