Hi,

What would be the optimal way, performance-wise, to work with Subset of pages as far PdfViewer is concerned ?

The subset would always be contiguous, e.g. Page 32-128. From the user perspective, only that Subset exists.
Some PDFs might be in the few 100s of MB, so extracting spans of pages to file is out of the question, it should be in-memory.

Bearing in mind I am just getting acquainted with Pdfium, so far I have considered the following strategies:
  • Inherit _startPage and _endPage
  • ImportPages in a new virtual Document (seems performance-unfriendly)

What view mode should support this behavior?
Should it be SinglePageView, VerticalView, HorizontalView or each of them?

SinglePageView and VerticalView minimum.
HorizontalView is a plus.

Thank you for your work on the rendering issue Paul and the team.

Any update on this question ?
I'm just looking for confirmation or pointers. Is inheriting _startPage and _endPage the way to go ?
