Thanks for your inquiry. Please note that MS Word document is flow document and does not contain any information about its layout into lines and pages. Therefore, technically there is no “Page” concept in Word document. Pages are created by Microsoft Word on the fly.
Aspose.Words uses our own Rendering Engine to layout documents into pages. Please check using the DocumentLayoutHelper sample from the offline samples pack. This sample demonstrates how to easily work with the layout elements of a document and access the pages, lines, rows, spans etc.
Hope this helps you. Please let us know if you have any more queries.
