From 818b0cc1b8b0c4acc565e8e2cb8b0b61aa5a300e Mon Sep 17 00:00:00 2001 From: "caryclark@google.com" Date: Mon, 8 Apr 2013 11:50:46 +0000 Subject: Add implementation of path ops This CL depends on https://codereview.chromium.org/12880016/ "Add intersections for path ops" Given a path, iterate through its contour, and construct an array of segments containing its curves. Intersect each curve with every other curve, and for cubics, with itself. Given the set of intersections, find one with the smallest y and sort the curves eminating from the intersection. Assign each curve a winding value. Operate on the curves, keeping and discarding them according to the current operation and the sum of the winding values. Assemble the kept curves into an output path.
