* Stop using SkTSwap.Gravatar Ben Wagner2018-06-19
| | | | | | | | | | | | | Use std::swap instead. It does not appear that any external user specializes SkTSwap, but some may still use it. This removes all use in Skia so that SkTSwap can later be removed in a smaller CL. After that the <utility> include can be removed from SkTypes.h.

* fix fuzzersGravatar caryclark2016-10-20
| | | | | | | | | | | | | | | Many old pathops-related fuzz failures have built up while the codebase was under a state a flux. Now that the code is stable, address these failures. Most of the CL plumbs the debug global state to downstream routines so that, if the data is not trusted (ala fuzzed) the function can safely exit without asserting.

* 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.

* harden and speed up path op unit testsGravatar caryclark@google.com2013-07-16
| | | | | | | | | | | | | | | | | | | PathOps tests internal routines direcctly. Check to make sure that test points, lines, quads, curves, triangles, and bounds read from arrays are valid (i.e., don't contain NaN) before calling the test function. Repurpose the test flags. - make 'v' verbose test region output against path output - make 'z' single threaded (before it made it multithreaded) The latter change speeds up tests run by the buildbot by 2x to 3x.

* path ops near exactGravatar caryclark@google.com2013-07-15
| | | | | | | | | | | | | | | | | Modify line intersections to first - match exact ends - compute intersections - match near ends where the exact ends are preferred, then near matches, then computed matches. This pulls matches towards existing end points when possible, and keeps intersection distances consistent with different line/line line/quad and line/cubic computations.

* Add intersections for path opsGravatar caryclark@google.com2013-04-08
This CL depends on https://codereview.chromium.org/12827020/ "Add base types for path ops" The intersection of a line, quadratic, or cubic with another curve (or with itself) is found by solving the implicit equation for the curve pair. The curves are first reduced to find the simplest form that will describe the original, and to detect degenerate or special-case data like horizontal and vertical lines. For cubic self-intersection, and for a pair of cubics, the intersection is found by recursively approximating the cubic with a series of quadratics. The implicit solutions depend on the root finding contained in the DCubic and DQuad structs, and the quartic root finder included here.
