Load multiple pages with [page] attribute option

I want to set page ranges (like 3-5) for a 7 page PDF document which is already rendered in the PDF viewer. How to achieve this with [page] attribute ?

The [(page)] attribute controls which page is shown first when the PDF is loaded (or when the attribute changes). Hence it takes a simple number.

What do you want to achieve with the page range? Does "3-5" mean that the first pages are excluded from the PDF viewer, so you can't scroll to these pages?

Yes.. 3-5 range means user will have to see the 3rd, 4th & 5th pages only from original 7 page document.
I am expecting same as how google chrome print range works.

After an hour of Googling, I believe that Mozilla's PDF.js library doesn't support that feature. ngx-extended-pdf-viewer is a simple wrapper around PDF.js, so that's bad news.

However, I can offer a workaround. Have you discovered the Hummus library already? Among many things, it can generate PDF files consisting of a few pages of the original file. As far as I can see, it's a server-side library.
