* use reversePathTo in place of addPathReverseGravatar caryclark2016-11-07
| | | | | | | | | | | | | | Path ops was using addPathReverse, instead of reversePathTo. The former adds a moveTo always, and the latter requires that the caller add the moveTo if needed. Simplify the reversePathTo implementation.

* 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.

* Rewriting path writerGravatar caryclark2016-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | The path writer takes constructs the output path out of curves that satisfy the pathop operation. Curves contain lists of t/point pairs that may not be comparable to each other. To match up curve ends in the output path, look for adjacent curves to have a shared membership rather than comparing point values. Use path utilities to connect partial curve lists into closed contours. Share the angle code that determines if a curve has become a degenerate line with the path writer. Clean up some code on the way, and delete some unused functions.

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.

* Add base types for path opsGravatar caryclark@google.com2013-04-08
Paths contain lines, quads, and cubics, which are collectively curves. To work with path intersections, intermediary curves are constructed. For now, those intermediates use doubles to guarantee sufficient precision. The DVector, DPoint, DLine, DQuad, and DCubic structs encapsulate these intermediate curves. The DRect and DTriangle structs are created to describe intersectable areas of interest. The Bounds struct inherits from SkRect to create a SkScalar-based rectangle that intersects shared edges. This also includes common math equalities and debugging that the remainder of path ops builds on, as well as a temporary top-level interface in include/pathops/SkPathOps.h.
