Missing content when converting PDF to image (png, jpeg) with Aspose.pdf. NET


I’m facing an issue when converting a PDF to a png image (when converting to jpeg image too).
No error is thrown, but some text and labels are missing in the generated image.

I figured out that this behaviour occurs when the source pdf has been built by “PDF Creator Pilot”.

I’m using the latest version of Aspose.PDF (v23.12).
Here is the code I run :

public static void ConvertPdfToPng(string pdfFilename)
            var pdfDocument = new Document(pdfFilename);

            foreach (var pdfPage in pdfDocument.Pages)
                var pngFilename = pdfFilename.Replace(".pdf", $"{pdfPage.Number}.png");

                using (var imageFileStream = new FileStream(pngFilename, FileMode.Create))
                    var resolution = new Resolution(300);
                    var pngDevice = new PngDevice(resolution);
                    pngDevice.Process(pdfPage, imageFileStream);

Here’s the source pdf : 5-22xB499xAVE408 - 2212231295.pdf (78.1 KB)

And the generated image : 5-22xB499xAVE408 - 22122312951.png (656.3 KB)
