System.NullReferenceExcept PDF printing after image replace

[[email protected]]

I am having trouble with printing a pdf after replacing an image in that PDF.

PdfImage image = PdfImage.FromImage(bmp);
PdfPageBase page = doc.Pages[0];
page.ReplaceImage(0, image);
doc.Print();

The will work if I save the pdf to file and then reload it before the print.

If you were using an old version, I first suggest you use the latest Spire.PDF Pack(Hot Fix) Version:5.1.16.
If the issue still happens, please provide your input PDF for further investigation.
