A compound path contains two or more paths, holes are drawn where the paths overlap. All the paths in a compound path take on the style of the backmost path and can be accessed through its item.children list.
Creates a new compound path item and places it in the active layer.
Example — Create a circle shaped path with a hole in it:
If this is a compound path with only one path inside, the path is moved outside and the compound path is erased.
Otherwise, the compound path is returned unmodified.
Smooth bezier curves without changing the amount of segments or their points, by only smoothing and adjusting their handle points, for both open ended and closed paths.
Example — Smoothing a closed shape:
Example
If called on a CompoundPath, a new Path is created as a child and the point is added as its first segment. On a normal empty Path, the point is simply added as its first segment.
Draws a curve from the position of the last segment point in the path that goes through the specified through point, to the specified to point by adding one segment to the path.
Example — Interactive example. Click and drag in the view below:
Draws an arc from the position of the last segment point in the path that goes through the specified through point, to the specified to point by adding one or more segments to the path.

Closes the path. When closed, Paper.js connects the first and last segments.
See also: path.closed
If called on a CompoundPath, a new Path is created as a child and the point is added as its first segment relative to the position of the last segment of the current path.
Adds a segment relative to the last segment point of the path.
Example
Example — Drawing a spiral using lineBy:
The name of the item. If the item has a name, it can be accessed by name through its parent's children list.
Example
The item's position within the project. This is the rectangle.center of the item's bounds rectangle.
Example — Changing the position of a path:
Example — Changing the x coordinate of an item's position:
Specifies whether the item is visible. When set to false, the item won't be drawn.
Example — Hiding an item:
The blend mode of the item.
Example — Setting an item's blend mode:
The opacity of the item as a value between 0 and 1.
Example — Making an item 50% transparent:
Specifies whether the item functions as a guide. When set to true, the item will be drawn at the end as a guide.
Specifies whether an item is selected and will also return true if the item is partially selected (groups with some selected or partially selected paths).
Paper.js draws the visual outlines of selected items on top of your project. This can be useful for debugging, as it allows you to see the construction of paths, position of path curves, individual segment points and bounding boxes of symbol and raster items.
See also: project.selectedItems, segment.selected, point.selected
Example — Selecting an item:
Specifies whether the item defines a clip mask. This can only be set on paths, compound paths, and text frame objects, and only if the item is already contained within a clipping group.
The item that this item is contained within.
Example
var path = new Path(); // New items are placed in the active layer: console.log(path.parent == project.activeLayer); // true var group = new Group(); group.addChild(path); // Now the parent of the path has become the group: console.log(path.parent == group); // true
The children items contained within this item. Items that define a name can also be accessed by name.
Please note: The children array should not be modified directly using array functions. To remove single items from the children list, use item.remove(), to remove all items from the children list, use item.removeChildren(). To add items to the children list, use item.addChild(item) or item.insertChild(index, item).
Example — Accessing items in the children array:
Example — Accessing children by name:
Example — Passing an array of items to item.children:
The first item contained within this item. This is a shortcut for accessing item.children[0].
The next item on the same level as this item.
The previous item on the same level as this item.
The bounding rectangle of the item including stroke width.
The bounding rectangle of the item including handles.
The width of the stroke.
Example — Setting an item's stroke width:
The shape to be used at the corners of paths when they have a stroke.
Example — A look at the different stroke joins:
The dash offset of the stroke.
Specifies an array containing the dash and gap lengths of the stroke.
Example
The miter limit of the stroke.
When two line segments meet at a sharp angle and miter joins have been specified for item.strokeJoin, it is possible for the miter to extend far beyond the item.strokeWidth of the path. The miterLimit imposes a limit on the ratio of the miter length to the item.strokeWidth.
When passed a project, copies the item to the project, or duplicates it within the same project. When passed an item, copies the item into the specified item.
Rasterizes the item into a newly created Raster object. The item itself is not removed after rasterization.
Example — Rasterizing an item:
Perform a hit test on the item (and its children, if it is a Group or Layer) at the location of the specified point.
The optional options object allows you to control the specifics of the hit test and may contain a combination of the following values:
tolerance: Number - The tolerance of the hit test in points.
options.type: Only hit test again a certain item type: PathItem, Raster, TextItem, etc.
options.fill: Boolean - Hit test the fill of items.
options.stroke: Boolean - Hit test the curves of path items, taking into account stroke width.
options.segment: Boolean - Hit test for segment.point of Path items.
options.handles: Boolean - Hit test for the handles (segment.handleIn / segment.handleOut) of path segments.
options.ends: Boolean - Only hit test for the first or last segment points of open path items.
options.bounds: Boolean - Hit test the corners and side-centers of the bounding rectangle of items (item.bounds).
options.center: Boolean - Hit test the rectangle.center of the bounding rectangle of items (item.bounds).
options.guide: Boolean - Hit test items that have item.guide set to true.
options.selected: Boolean - Only hit selected items.
