To my knowledge, MakeGrayScale property is to convert a page to gray scale. I have used the following code:
static string destinationpath = Application.StartupPath + @"\AsposeUtility";
Aspose.Pdf.Document doc = new Aspose.Pdf.Document(sourceMsgPath);
foreach (Page page in doc.Pages)
doc.Save(destinationpath + “ParsedPdf.pdf”);
Is this the right way to save the same pdf doc after making changes to the pages of the pdf ? Also , can you please let me know,if there’s a way to export the existing color pdf to black and white pdf ?
