How to convert a text-type PDF to an image-type pdf that cannot be edited or copied

How to convert a text-type PDF to an image-type pdf that cannot be edited or copied?
I tried to convert each page of the PDF document into a image, and then merge all the images into a new PDF document, but that would be more troublesome.Is there a quicker way to implement Aspose.pdf?
