2017-10-04Unify parsing of cross ref table v4.Artem Strygin
We can use 'Prev' value of first-page cross-reference table trailer for load main cross-reference table, instead of 'T' value of Linearized header (Offset of first entry in main cross-reference table). This is better solution, because this is allow us check entry count in main cross-ref table and unify loading of main cross-ref table with loading methods of non linearized document. See PDF specification: http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/PDF32000_2008.pdf#678 (page 678, Example 3/part 3) Change-Id: I59dcf3c73a0fb561221ded78e827e40535dbd717 Reviewed-on: https://pdfium-review.googlesource.com/13810 Commit-Queue: Art Snake <art-snake@yandex-team.ru> Reviewed-by: dsinclair <dsinclair@chromium.org>
