There are multiple settings in PDF-Tools that feature Page Range specification:
Figure 1. Page Range Setup Dialog Box
•Select All to specify to all pages.
•Select Custom to specify a custom page range:
•Use commas to delimiter individual pages.
•Use hyphens to delimiter page ranges.
•Use commas to delimiter page ranges if multiple page ranges are being defined.
•Use a dash before a page number to determine all pages from the beginning of the document to the specified page. For example -7 defines all pages from the beginning of the document to page seven.
•Use a dash after a page number to determine all pages from the specified page to the end of the document. For example 7- defines all pages from page seven to the end of the document.
•Use the caret symbol (^n) to specify the document page that is n pages from the end of the document, or use (^n-^n) to specify a page range from the end of the document. For example, ^2 specifies the second-last page of the document, and ^1-^5 specifies the last five pages of the document.
•Use the Subset menu to specify a subset of custom page ranges as desired. The options are All Pages, Odd Pages Only and Even Pages Only.
•Note that when you are specifying a custom page range it is not necessary for the order of pages to be sequential, or for each value in the range to be unique.
