From 4bd0d99c11102514fb43328b67b7674165888619 Mon Sep 17 00:00:00 2001 From: Nicolas Pena Date: Thu, 2 Feb 2017 14:32:21 -0500 Subject: Add CPDF_PageContentGenerator::ProcessPath supporting path construction MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit See Table 4.9 for path construction operators. Ignoring v, y, because those can be replaced with the more powerful c operator. The code added will be called by public methods that do not exist yet.
