### Changed ### Changed
- Loosely couple Node.js / Electron code to Canvas module, and treat its absence - Loosely couple Node.js / Electron code to Canvas module, and treat its absence
like a headless web worker context in the browser (#1103). like a headless web worker context in the browser (#1103).
- Split `PathItem#resolveCrossings()` into `#resolveCrossings()` and
`#reorient()` (#973).
- Clean up handling of `Item#_set()`, `#set()` and `#initialize()`:
- `#_set()` is for actually setting internal properties, e.g. on `Point`,
`Size`, so that derived classes can reuse other parts without having to
override each individual function (e.g. in `SegmentPoint`)
- `#set()` is a shortcut to `#initialize()` on all basic types, to offer the
same amount of flexibility when setting values, accepting object literals
as well as lists of value arguments.
- Add support for shorter `h` / `v` commands for horizontal / vertical lines in
SVG output.
- Implement new and shorter segments array notation:
- Close paths by including `true` as the last entry
- Allow nested segment arrays to be passed to `PathItem.create()` as well as
the `CompoundPath` constructor to create all sub-paths.
- Reflect `View#zoom` and `View#center` through matrix decomposition, and
implement additional decomposed properties such as `#scaling` and `#rotation`.
- Reduce various internal epsilon values for general improved precision while
maintaining reliability.
### Added
- Add `PathItem#compare()` as a way to compare the geometry of two paths to see
if they describe the same shape, handling cases where paths start in different
segments or use different amounts of curves to describe the same shape.
- Implement `Curve#hasLength()` as an optimized check for curve-length (#1109).
- Implement `Path#divideAt()`, similar to `Curve#divideAt()`.
- Node.js: Support v7, and keep testing v4 up to v7 in Travis CI.
- Bring back caching of `Item#rotation` and `#scaling`, but only allow matrix
decomposition-based properties on items with `#applyMatrix = false`
(#1004, #1177).
- Implement `Curve#classify()` to determine the type of cubic Bézier curve via
discriminant classification, based on an approach described by Loop and Blinn,
and use it to simplify curve self-intersection handling (#773, #1074, #1235).
- Add `Curve.getPeaks()` as a fast way to retrieve points that are often similar
to the more costly curvature extrema for use in curve offsetting.
- Expose `Curve. getCurveLineIntersections()` for use in curve offsetting.
- Add `Line.getDistance()` and use it in `Curve.getOverlaps()` (#1253).
- Implement `Segment#isSmooth()` and use it in handling of stroke-joins.
### Fixed ### Fixed
- Many improvements to boolean operations:
- Improve performance of boolean operations when there no actual crossings
between the paths, but paths may be contained within each other.
- Improve path tracing approach by implementing a branching structure and
sorting segments according to their reliability as starting points for
traces (#1073).
- Improve calculation and reliability of winding contributions.
- Improve code that resolves crossings and reorients compound-paths based
on how the sub-paths are nested.
- Fix issue where unite operation wrongly fills inner path (#1075).
- Better handle cases where one `Path` is open and the other closed (#1089).
- Solve `null` exceptions during complex boolean operations (#1091).
- Improve bidirectional curve-time rescaling in `divideLocations()` (#1191).
- Improve handling of intersections between touching curves (#1165).
- Improve reliability of `Curve#getIntersections()` (#1174).
- Fix `getOverlaps()` to always return overlaps in correct sequence (#1223).
- Improve handling of multiple crossings on the same curve.
- Improve and optimize fat-line clipping algorithm by checking if subdivided
curves are straight and falling back on line-line / line-curve approach if
they are.
- Improve tangent direction handling in `CurveLocation#isCrossing()`, by finding
unambiguous vectors, taking inception points and "peaks" into account
(#1073, #1074).
- Prevent `Path#getStrokeBounds(matrix)` from accidentally modifying segments - Prevent `Path#getStrokeBounds(matrix)` from accidentally modifying segments
(#1102). (#1102).
- Compatibility with JSPM (#1104). - Improve compatibility with JSPM (#1104).
- SVG Import: Correctly handle multiple sequential move commands (#1134).
- SVG Export: Properly handle generated IDs (#1138).
- SVG Export: Support multiple gradient offsets at 0 (#1241).
- Fix imprecision in `Numerical.findRoot()` (#1149).
- PaperScript: Prevent invalid JavaScript in assignment operators (#1151).
- Hit Tests: Improve handling of SymbolItem in#hitTestAll() (#1199).
- Hit Tests: Fix stroke hit-testing for rounded shape items (#1207).
- Fix matrix cloning for groups with `#applyMatrix = false` ( #1225).
- Correctly handle offset in `Curve#divideAt(offset)` (#1230).
- Fix `Line#getSide()` imprecisions when points are on the line.
- Docs: Fix documentation of `Project#hitTestAll()` (#536).
- Docs: Improve description of option.class value in `Project#hitTest()` (#632).
### Removed
- Remove `Numerical.TOLERANCE = 1e-6` as there is no internal use for it\
anymore.
