How can i remove already existed page number...?

I am trying to add Page numbers in a pdf which already have page numbers at page bottom.
Now I want to remove the preassigned page numbers and add new page numbers from initial....
I didn't find any method like addfooter or removefooter(even fileStamp existing...)..Is there any method to do so.....through which I can edit the footer of the pdf file.

I am also looking for how can I edit Header of a pdf file.

Hi,

Thank you for considering Aspose.

Removing page number is not supported directly. As a workaround you can stamp a blank image at the position of the page number.

As for editing page header, it is also not supported directly. You can try replacing text or stamp image.
