paperjs/paper.js v0.14.0

on GitHub

Added

• Add options.handlers to PaperScript.execute(), to export further global
  handlers next to onFrame, onResize and the tool's, for hosts that call
  them themselves, such as Scriptographer's onStop.
• Add Tool#eventInterval, as Scriptographer had it, to fire onMouseDrag again
  at an interval while the mouse button is held, also when the mouse doesn't
  move.
• Add Project#scope, View#scope, Item#scope and Tool#scope, to get from
  each of them to its PaperScope (#1634).
• Add Group#isolated, to draw a group or layer through a temporary canvas, so
  that the blend modes of its children, such as 'destination-out', only apply
  within it, like CSS's isolation: isolate (#474).
• Add View#dispatchMouseEvent() and View#dispatchKeyEvent(), to feed mouse
  and key events from hosts without a DOM, such as workers, through the same
  handling as the DOM's events, for tools, items and views.
• Add settings.scaleStrokes, to scale the stroke widths of paths and
  compound paths along with their content when matrices are applied (#2098,
  #1514).
• Add the paper-sourced.js build, in which a project's items can be backed
  by a host document through Project#source: items are created as light
  shells from the host's records, and load their content and children from
  the host on first access, so a script costs what it touches. Includes
  HostItem, for the host's own kinds of nodes (#2203).
• Add Project#trackChanges and Project#takeChanges(), to let hosts that
  keep their own document update only the items that changed, and export
  ChangeFlag (#2202).

Changed

• Path.RegularPolygon() follows Illustrator: it stands on a flat bottom edge
  for any number of sides, and its segments run counterclockwise from its top
  vertex, or with an even number of sides, from the right end of its top edge.
  This changes the segment order of all regular polygons, and turns those with
  a multiple of 6 sides onto an edge (#1787).
• Hit-test transparent fills, as in SVG: only items without a fill color are
  not hit through their fill (#1157).
• paper.install() keeps what the target scope has already, such as the
  native Event, MouseEvent and Symbol, and PaperScript doesn't shadow
  existing globals with Paper.js's classes of the same name either (#1832,
  #1652).
• Item#importJSON() into an existing item resets the fields that the JSON
  leaves out, so the item ends up the same as a newly imported one, with its
  place in the scene graph and its event handlers kept (#1425, #1324).
• Canvases without resize get their CSS size from the view on every screen,
  not only at pixel ratios other than 1, where the page's CSS won (#2088).
• #hitTestAll() reports every segment and handle of a path within the
  tolerance, closest first, followed by its stroke or fill hit, instead of only
  the first hit per path (#1294).

Fixed

• Create the tool in PaperScript for all of its global handlers, also for
  scripts that only define onActivate() or onDeactivate(), and document
  Tool#onActivate and Tool#onDeactivate.
• Keep Key.modifiers in sync with the flags of mouse events, so modifier keys
  pressed or released while the page didn't have the focus don't stay wrong
  (#1140).
• Keep Paper.js's own blend modes, which CSS doesn't have, such as
  'destination-out', through SVG export and import, in a
  data-paper-blend-mode attribute (#1296).
• Throw a clear error when creating an item without a project, instead of a
  null access deep inside the constructor (#1889).
• Free the pixels of temporary canvases when they're released, which their pool
  kept allocated at their largest size for the life of the page.
• Keep the size of rasters in JSON, so imported rasters have their size and
  bounds before their image has loaded, or if it fails to load (#1598).
• Fix the frame timer of workers and Node.js running forever after any script,
  which kept hosts from seeing scripts end.
• Fix touch scrolling over empty parts of a canvas whose items have mouse
  handlers (#1930).
• Fix mouse events reaching items and views through elements that cover the
  canvas, such as menus. Drags still reach beyond them (#992).
• Fix the points of #hitTestAll() results of items inside transformed
  groups, which were in the items' own coordinates.
• Support strokeScaling: false on text, exactly for uniform scaling (#1703).
• Fix the view size of canvases inside elements with CSS transforms, which
  only scale the canvas on screen.
• Fix italic and oblique font weights in SVG export and import, which SVG
  keeps in font-style (#937).
• Fix onFrame in web workers, where views have no element (#2200).
• Fix PaperScope#execute() in web workers (#2201).
