When exporting pages as PNG charts are flipped

12345678.pdf (3.2 MB)

static void Main(string[] args)
FileStream stream = new FileStream(“c:\temp\12345678.pdf”, FileMode.Open);
Document doc = new Document(stream);
PdfPageEditor editor = new PdfPageEditor(doc);
using (MemoryStream memoryStream = new MemoryStream())
new BmpDevice(new Resolution(300)).Process(doc.Pages[15], memoryStream);
Image b = Bitmap.FromStream(memoryStream);



We used following code snippet in our environment with Aspose.PDF for .NET 20.10 and did not notice any issue:

Document pdfDocument = new Document(dataDir + "12345678.pdf");
for (int pageCount = 1; pageCount <= pdfDocument.Pages.Count; pageCount++)
 string tmpImgToInsert = DateTime.Now.Ticks + ".png";
 using (FileStream imageStream = new FileStream(dataDir + tmpImgToInsert, FileMode.Create))
 var pngDevice = new PngDevice(new Resolution(300))
  RenderingOptions = new RenderingOptions()
   UseFontHinting = true
 pngDevice.Process(pdfDocument.Pages[pageCount], imageStream);
