* 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.

Extended tests (150M+) run to completion in release in about 6 minutes; the standard test suite exceeds 100K and finishes in a few seconds on desktops.

* cumulative pathops patchGravatar caryclark2015-03-26
| | | | | | | | | | | | | | | | | | | | | Replace the implicit curve intersection with a geometric curve intersection. The implicit intersection proved mathematically unstable and took a long time to zero in on an answer. Use pointers instead of indices to refer to parts of curves. Indices required awkward renumbering. Unify t and point values so that small intervals can be eliminated in one pass. Break cubics up front to eliminate loops and cusps. Make the Simplify and Op code more regular and eliminate arbitrary differences. Add a builder that takes an array of paths and operators. Delete unused code.

* Fix last pathops skp bugGravatar caryclark2014-06-18
| | | | | | | | | | | | | | | | | | | | | | This fixes the last bug discovered by iterating through the 800K skp corpus representing the top 1M websites. For every clip on the stack, the paths are replaced with the pathop intersection. The resulting draw is compared with the original draw for pixel errors. At least two prominent bugs remain. In one, the winding value is confused by a cubic with an inflection. In the other, a quad/cubic pair, nearly coincident, fails to find an intersection. These minor changes include ignoring very tiny self-intersections of cubics, and processing degenerate edges that don't connect to anything else.

* 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.

* convert pathops to use SkSTArray where possible.Gravatar caryclark@google.com2013-06-17
| | | | | | | | | | | | | | | | | | Replace SkTDArray with SkTArray and use SkSTArray when the probable array size is known. In a couple of places (spans, chases) the arrays are constructed using insert() so SkTArrays can't be used for now. Also, add an optimization to cubic subdivide if either end is zero or one.

* 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
