Changed

  • Node.js: Support v7, and keep testing v4 up to v7 in Travis CI.
  • Node.js: Loosely couple Node.js / Electron code to Canvas module, and treat
    its absence like a headless web worker context in the browser (#1103).
  • Clean up handling of Item#_set(), #set() and #initialize():
    • Use #_set() 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)
    • Define #set() as 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.
  • SVG Export: Add support for shorter h / v commands for horizontal /
    vertical lines in SVG output.
  • JSON Import / Export: 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.
  • Split PathItem#resolveCrossings() into #resolveCrossings() and
    #reorient() (#973).

Added

  • Implement Path#divideAt(location), in analogy to Curve#divideAt(location).
  • 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 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.
  • Bring back caching of Item#rotation and #scaling, but only allow matrix
    decomposition-based properties on items with #applyMatrix = false
    (#1004, #1177).

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 tangent direction handling in CurveLocation#isCrossing(), by finding
    unambiguous vectors, taking the curve's loop, cusp, inflection, and "peak"
    points into account (#1073, #1074).
  • Prevent Path#getStrokeBounds(matrix) from accidentally modifying segments
    (#1102).
  • 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 issue with Curve#isStraight() where handles were checked incorrectly
    for collinearity (#1269).
  • 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.
