* Enabling the canvas bit to turn the clip stack into a flat replace exposed ↵Gravatar caryclark2014-06-17
| | | | | | | | | | | | | | | | | | around 100 failures when testing the 800K skp set generated from the top 1M web sites. This fixes all but one of those failures. Major changes include: - Replace angle indices with angle pointers. This was motivated by the need to add angles later but not renumber existing angles. - Aggressive segment chase. When the winding is known on a segment, more aggressively passing that winding to adjacent segments allows fragmented data sets to succeed. - Line segments with ends nearly the same are treated as coincident first. - Transfer partial coincidence by observing that if segment A is partially coincident to B and C then B and C may be partially coincident.

* Mike R: please sanity check SkPostConfig.hGravatar commit-bot@chromium.org2014-04-14
| | | | | | | | | | | | | | | | | | | | | | | | Mike K: please sanity check Test.cpp and skia_test.cpp Feel free to look at the rest, but I don't expect any in depth review of path ops innards. Path Ops first iteration used QuickSort to order segments radiating from an intersection to compute the winding rule. This revision uses a circular sort instead. Breaking out the circular sort into its own long-lived structure (SkOpAngle) allows doing less work and provides a home for caching additional sorting data. The circle sort is more stable than the former sort, has a robust ordering and fewer exceptions. It finds unsortable ordering less often. It is less reliant on the initial curve tangent, using convex hulls instead whenever it can. Additional debug validation makes sure that the computed structures are self-consistent. A new visualization tool helps verify that the angle ordering is correct. The 70+M tests pass with this change on Windows, Mac, Linux 32 and Linux 64 in debug and release.

* path ops -- rewrite angle sortGravatar caryclark@google.com2013-06-04
| | | | | | | | | | | | | | | | | | | | | | | | This is a major change resulting from a minor tweak. In the old code, the intersection point of two curves was shared between them, but the intersection points and end points of sorted edges was computed directly from the intersection T value. In this CL, both intersection points and sorted points are the same, and intermediate control points are computed to preserve their slope. The sort itself has been completely rewritten to be more robust and remove 'magic' checks, conditions that empirically worked but couldn't be rationalized. This CL was triggered by errors generated computing the clips of SKP files. At this point, all 73M standard tests work and at least the first troublesome SKPs work.

* Add implementation of path opsGravatar caryclark@google.com2013-04-08
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. Review URL: https://codereview.chromium.org/13094010 git-svn-id: http://skia.googlecode.com/svn/trunk@8553 2bbb7eff-a529-9590-31e7-b0007b416f81
