From 9c6204fc6c23ab35ec234781df182da570f6faef Mon Sep 17 00:00:00 2001 From: Lei Zhang Date: Tue, 8 May 2018 19:20:57 +0000 Subject: Add APIs to work with a FPDF_PAGERANGE. After getting a FPDF_PAGERANGE from FPDF_VIEWERREF_GetPrintPageRange(), one can now use FPDF_VIEWERREF_GetPrintPageRangeCount() to get the number of elements in the FPDF_PAGERANGE. One can then use FPDF_VIEWERREF_GetPrintPageRangeElement() to read the elements.
