Getting almost white page when converting PDF file to Png

Hi,

I’m experiencing an issue when converting PDF file to Png.
The rendered png is almost empty / white.

Here is the code I run, with Aspose.Pdf in v20.3.0.0 :

    var pdfFilename = @"D:\TestFile.pdf";
    var pdfDocument = new Document(pdfFilename);
    int pageRank = 1;
    foreach (var pdfDocumentPage in pdfDocument.Pages)
    {
        var pngFileName = pdfFilename.Replace(".pdf", $"-{pageRank}.png");
        using (var imageFileStream = new FileStream(pngFileName, FileMode.Create))
        {
            var resolution = new Resolution(300);
            var pngDevice = new PngDevice(resolution);
            pngDevice.Process(pdfDocumentPage, imageFileStream);
            imageFileStream.Close();
        }
        pageRank++;
    }

And here is the pdf used; Facture 4137394.pdf (109.0 KB)
