* move parts of SkPoint to SkPointPrivGravatar Cary Clark2017-11-08
| | | | | | | | | | | | Move specialized SkPoint methods to SkPointPriv. Use constexpr and inline initialization where possible.

* 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.

* Change SkTime::GetMSecs to double; ensure values stored in SkMSec do not ↵Gravatar benjaminwagner2016-03-25
| | | | | | | | | | | | | | | | | | | | | | | overflow. The following are currently unused in Android, Google3, Chromium, and Mozilla: - SkEvent - SkTime::GetMSecs - SK_TIME_FACTOR (also unused in Skia) - SkAutoTime I left uses of SkMSec more-or-less intact for SkEvent, SkAnimator, and SkInterpolator. SkInterpolator is used in Chromium, so I did not want to change the API. The views/ and animator/ code is crufty, so it didn't seem worthwhile to refactor it. Instead, I added SkEvent::GetMSecsSinceStartup, which is likely to be adequate for use in SampleApp. I also left SkMSec where it is used to measure a duration rather than a timestamp. With the exception of SkMovie, which is used in Android, all of the uses appear to measure the execution time of a piece of code, which I would hope does not exceed 2^31 milliseconds. Added skiatest::Timer to support a common idiom in tests where we want to measure the wallclock time in integer milliseconds. (Not used in tests/PathOpsSkpClipTest.cpp because it redefines things in Test.h.) Removed tabs in tests/StrokerTest.cpp. BUG=skia:4632 GOLD_TRYBOT_URL= https://gold.skia.org/search2?unt=true&query=source_type%3Dgm&master=false&issue=1811613004 Review URL: https://codereview.chromium.org/1811613004
* There can be only one (SkRandom)!Gravatar scroggo2014-12-15
| | | | | | | | | | | | | | | | | | | | | Remove SkLCGRandom. We already decided the new one was better, which is why we wrote the new SkRandom. Convert GMs that were using SkLCGRandom to use the improved SkRandom. Motivated by the fact that these GMs draw differently on some runs. We believe this to be a result of using the old SkLCGRandom. Add each of the tests that were using SkLCGRandom to ignore-tests.txt, since we expect they'll draw differently using SkRandom. Move a trimmed down version of SkLCGRandom into SkDiscretePathEffect. In order to preserve the old behavior, trim down SkLCGRandom to only the methods used by SkDiscretePathEffect, and hide it in SkDiscretePathEffect's cpp file.

* Draw more accurate thick-stroked Beziers (disabled)Gravatar caryclark2014-10-09
Draw thick-stroked Beziers by computing the outset quadratic, measuring the error, and subdividing until the error is within a predetermined limit. To try this CL out, change src/core/SkStroke.h:18 to #define QUAD_STROKE_APPROXIMATION 1 or from the command line: CPPFLAGS="-D QUAD_STROKE_APPROXIMATION=1" ./gyp_skia Here's what's in this CL: bench/BezierBench.cpp : a microbench for examining where the time is going gm/beziers.cpp : random Beziers with various thicknesses gm/smallarc.cpp : a distillation of bug skia:2769 samplecode/SampleRotateCircles.cpp : controls added for error, limit, width src/core/SkStroke.cpp : the new stroke implementation (disabled) tests/StrokerTest.cpp : a stroke torture test that checks normal and extreme values The new stroke algorithm has a tweakable parameter: stroker.setError(1); (SkStrokeRec.cpp:112) The stroke error is the allowable gap between the midpoint of the stroke quadratic and the center Bezier. As the projection from the quadratic approaches the endpoints, the error is decreased proportionally so that it is always inside the quadratic curve. An overview of how this works: - For a given T range of a Bezier, compute the perpendiculars and find the points outset and inset for some radius. - Construct tangents for the quadratic stroke. - If the tangent don't intersect between them (may happen with cubics), subdivide. - If the quadratic stroke end points are close (again, may happen with cubics), draw a line between them. - Compute the quadratic formed by the intersecting tangents. - If the midpoint of the quadratic is close to the midpoint of the Bezier perpendicular, return the quadratic. - If the end of the stroke at the Bezier midpoint doesn't intersect the quad's bounds, subdivide. - Find where the Bezier midpoint ray intersects the quadratic. - If the intersection is too close to the quad's endpoints, subdivide. - If the error is large proportional to the intersection's distance to the quad's endpoints, subdivide.
