Performance improvement for navigating named destinations in PDF documents

Abstract

PDF (Portable Document Format) documents have become popular in recent times. PDF documents have named destinations that have reference to info like page number, zoom level, scale factor etc. These named destinations should be resolved when user loads URL with named destination or select link in the PDF. Resolving named destinations in PDF is taking more time that affects response time in PDF after user selection or resolving named destination at the URL load time for rendering PDF in Chrome Browser. In this paper, we present a new dictionary based novel solution for improving time to resolve named destinations. Dictionary is the map of named destinations and corresponding page number in the PDF document. We then present the results of some tests on the purposed approach with the already existing approach to show that the purposed approach performs better compared to existing approach while creation of named destinations dictionary does not take significant time. We conclude that our algorithm can perform better as asynchronous message passing is avoided and we have access to page number corresponding to the named destination in constant time and in synchronous manner.
