| | | | | | | | | | | | | | Curve intersections with extreme numbers may cause the intersection template code to loop forever.

* interpolation of coincidence must be local to a single spanGravatar caryclark2016-09-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pathops makes up intersections that it doesn't detect directly, but do exist. For instance, if a is coincident with b, and b is coincident with c, then for where they overlap a is coincident with c. The intersections are made up in different ways. In a few places, the t values that are detected are interpolated to guess the t values that represent invented intersections. The interpolated t is not necessarily linear, but a linear guess is good enough if the invented t lies between known t values. Additionally, improve debugging. This passes the extended release test suite and additionally passes the first 17 levels in the tiger test suite; previously, path ops passed 7 levels. The tiger suite is composed of 37 levels in increasing complexity, described by about 300K tests.

* pathops coincident workGravatar caryclark2016-08-31
| | | | | | | | | | | | | This is working towards fixing all bugs around simplifying the tiger. This installment simplifies the point-t intersection list as it is built rather than doing the analysis once the intersections are complete. This avoids getting the list in an inconsistent state and makes coincident checks faster and more stable.

| | | | | | | | | | | | | | | | The addT() function is a workhorse of pathops. Make it simpler, removing branches and parameters. Separate addOpp() into const and modify parts.

* add pathops debuggingGravatar caryclark2016-08-25
| | | | | | | | | | | | | | | | | | | Pathops has many points of failure, most of which are triggered by extreme data generated by fuzzers. It's difficult to figure out which failure point was triggered when the operation gives up. Add instrumentation so that the failure can be debugged when the data is well-behaved. Also, add a check that looks for a sequence of coincident points on multiple edges that are out of order when compared to each other.

* remove point aliasesGravatar caryclark2016-08-24
| | | | | | | | | | | | | | | | This removes the notion of keeping track of every different t value that resolves to the same or a similar point. Other fixes make this concept unnecessary, and removing it simplifies the code. This removes an allocation, and speeds up paths with many overlapping curves.

* pathops coincidence and security rewriteGravatar caryclark2016-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most changes stem from working on an examples bracketed by #if DEBUG_UNDER_DEVELOPMENT // tiger These exposed many problems with coincident curves, as well as errors throughout the code. Fixing these errors also fixed a number of fuzzer-inspired bug reports. * Line/Curve Intersections Check to see if the end of the line nearly intersects the curve. This was a FIXME in the old code. * Performance Use a central chunk allocator. Plumb the allocator into the global variable state so that it can be shared. (Note that 'SkGlobalState' is allocated on the stack and is visible to children functions but not other threads.) * Refactor Let SkOpAngle grow up from a structure to a class. Let SkCoincidentSpans grow up from a structure to a class. Rename enum Alias to AliasMatch. * Coincidence Rewrite Add more debugging to coincidence detection. Parallel debugging routines have read-only logic to report the current coincidence state so that steps through the logic can expose whether things got better or worse. More functions can error-out and cause the pathops engine to non-destructively exit. * Accuracy Remove code that adjusted point locations. Instead, offset the curve part so that sorted curves all use the same origin. Reduce the size (and influence) of magic numbers. * Testing The debug suite with verify and the full release suite ./out/Debug/pathops_unittest -v -V ./out/Release/pathops_unittest -v -V -x expose one error. That error is captured as cubics_d3. This error exists in the checked in code as well.

* fix security bugGravatar caryclark2016-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fix is a tradeoff. It changes intersection to treat a case where one coincident run is intersected at one point and the other edge is not as continuing to be a span. The old code tried to treat this as a single point. The old code is probably right, but this change alone made the data structures inconsistent. Later, extending the coincident runs would fail by incorrectly discarding the single point intersection. As a result, this fixes the security test and one other, but makes a different test fail. Isolating the failure uncovered a reduced case that fails with and without the change, so there are more serious problems here. Those problems are addressed in a separate CL. Many of the test edits below remove ill-thought out debugging messaging that fire off global state, which isn't usable in a multi-threaded test environment. In the end, with this fix, all existing tests (modulo one new failure and one new non-failure) pass in debug and in the extended release test suites.

| | | | | | | | | | | | | The C++ standard library uses the name "release" for the operation we call "detach". Rewriting each "detach(" to "release(" brings us a step closer to using standard library types directly (e.g. std::unique_ptr instead of SkAutoTDelete). This was a fairly blind transformation. There may have been unintentional conversions in here, but it's probably for the best to have everything uniformly say "release".

* add helper to create fancy underlinesGravatar caryclark2016-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a couple of utility functions to SkPaint that return the bounds of glyphs between a pair of lines. The common use case envisioned generates the edges of descenders between the top and bottom bounds of an underline to allow computing a stroke that skips those descenders. The implementation stores a linked list in each glyph containing the bounds of the lines parallel to the advance and the outermost intersections within those bounds. When the glyph cache is constructed, the glyph path is intersected with the bounds and the extreme min and max values within the bounds is added to an intercept. Share the text to path iter to construct the data. Make a half-hearted attempt to support vertical text; while the vertical implementation is complete; surrounding code (e.g. paint align) has short-comings with vertical.
