# TextItem

Extends `Item`

The TextItem type allows you to create typography. Its functionality is inherited by different text item types such as `PointText`, and `AreaText` (coming soon). They each add a layer of functionality that is unique to their type, but share the underlying properties and functions that they inherit from TextItem.

## Properties

`content`

The text contents of the text item.

#### Type:

- `String`

#### Example:Setting the content of a PointText item:

#### Example:

Run
`style`

The path style of the item.

#### Type:

- `Style`

#### Example:Applying several styles to an item in one go, by passing an object to its style property:

Run

#### Example:Copying the style of another item:

#### Example:Hiding an item:

Run
`blendMode`

The blend mode with which the item is composited onto the canvas. Both the standard canvas compositing modes, as well as the new CSS blend modes are supported. If blend-modes cannot be rendered natively, they are emulated. Be aware that emulation can have an impact on performance.

#### Values:

- `'normal'`, `'multiply'`, `'screen'`, `'overlay'`, `'soft-light'`, `'hard- light'`, `'color-dodge'`, `'color-burn'`, `'darken'`, `'lighten'`, `'difference'`, `'exclusion'`, `'hue'`, `'saturation'`, `'luminosity'`, `'color'`, `'add'`, `'subtract'`, `'average'`, `'pin-light'`, `'negation'`, `'source-over'`, `'source-in'`, `'source-out'`, `'source-atop'`, `'destination-over'`, `'destination-in'`, `'destination-out'`, `'destination-atop'`, `'lighter'`, `'darker'`, `'copy'`, `'xor'`

#### Example:

    var path = new Path();
    path.data.malcolm = new Point(20, 30);
    console.log(path.data.malcolm.x); // 20

            pets: ['Spot']
        }
    });
    console.log(path.data.pets.length); // 1

### Position and Bounding Boxes

`position`

The item’s position within the parent item’s coordinate system. By default, this is the `rectangle.center` of the item’s `bounds` rectangle.

#### Type:

#### Example:Changing the position of a path:

Run

#### Example:Changing the x coordinate of an item's position:

Run
`pivot`

The item’s pivot point specified in the item coordinate system, defining the point around which all transformations are hinging. This is also the reference point for `position`. By default, it is set to `null`, meaning the `rectangle.center` of the item’s `bounds` rectangle is used as pivot.

#### Default:

- `null`

#### Type:

- `Point`

`bounds`

The bounding rectangle of the item excluding stroke width.

#### Type:

Typical use case would be drawing a frame around the object where you want to draw something of the same size, position, rotation, and scaling, like a selection frame.

#### Type:

- `Rectangle`

`rotation`

The current rotation angle of the item, as described by its `matrix`. Please note that this only returns meaningful values for items with `applyMatrix` set to `false`, meaning they do not directly bake transformations into their content.

#### Type:

- `Number`

`scaling`

The current scale factor of the item, as described by its `matrix`. Please note that this only returns meaningful values for items with `applyMatrix` set to `false`, meaning they do not directly bake transformations into their content.

`matrix`

The item’s transformation matrix, defining position and dimensions in relation to its parent item in which it is contained.

#### Type:

- `Matrix`

`globalMatrix`

`viewMatrix`

The item’s global matrix in relation to the view coordinate space. This means that the view’s transformations resulting from zooming and panning are factored in.

Read only.

#### Type:

- `Matrix`

`applyMatrix`

Controls whether the transformations applied to the item (e.g. through `transform(matrix)`, `rotate(angle)`, `scale(scale)`, etc.) are stored in its `matrix` property, or whether they are directly applied to its contents or children (passed on to the segments in `Path` items, the children of `Group` items, etc.).

#### Default:

#### Type:

- `Boolean`

### Project Hierarchy

`project`

    var group = new Group();
    group.addChild(path);

    // Now the parent of the path has become the group:
    console.log(path.parent == group); // true

#### Example:Setting the parent of the item to another item

    var path = new Path();

    // New items are placed in the active layer:
    console.log(path.parent == project.activeLayer); // true

    var group = new Group();
    path.parent = group;

    // Now the parent of the path has become the group:
    console.log(path.parent == group); // true

    // The path is now contained in the children list of group:
    console.log(group.children[0] == path); // true

#### Example:Setting the parent of an item in the constructor

    var group = new Group();

    var path = new Path({
        parent: group
    });

    // The parent of the path is the group:
    console.log(path.parent == group); // true

    // The path is contained in the children list of group:
    console.log(group.children[0] == path); // true

`children`

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`().

`matches(options)`

Checks whether the item matches the criteria described by the given object, by iterating over all of its properties and matching against their values through `matches(name, compare)`.

See `project.getItems(options)` for a selection of illustrated examples.

#### Parameters:

#### Returns:

- ``Boolean`` — `true` if the item matches all the criteria, `false` otherwise

#### See also:

- ``getItems(options)``

`matches(name, compare)`

Checks whether the item matches the given criteria. Extended matching is possible by providing a compare function or a regular expression. Matching points, colors only work as a comparison of the full object, not partial matching (e.g. only providing the x-coordinate to match all points with that x-value). Partial matching does work for `item.data`.

See `project.getItems(options)` for a selection of illustrated examples.

#### Parameters:

- `name:` `String` — the name of the state to match against
- `compare:` `Object` — the value, function or regular expression to compare against

#### Returns:

- ``Boolean`` — `true` if the item matches the state, `false` otherwise

#### See also:

- ``getItems(options)``

`getItems(options)`

Fetch the descendants (children or children of children) of this item that match the properties in the specified object. Extended matching is possible by providing a compare function or regular expression. Matching points, colors only work as a comparison of the full object, not partial matching (e.g. only providing the x- coordinate to match all points with that x-value). Partial matching does work for `item.data`.

Matching items against a rectangular area is also possible, by setting either `options.inside` or `options.overlapping` to a rectangle describing the area in which the items either have to be fully or partly contained.

See `project.getItems(options)` for a selection of illustrated examples.

#### Options:

- `options.recursive: `Boolean`` — whether to loop recursively through all children, or stop at the current level — default: `true`
- `options.match: `Function`` — a match function to be called for each item, allowing the definition of more flexible item checks that are not bound to properties. If no other match properties are defined, this function can also be passed instead of the `options` object
- `options.class: `Function`` — the constructor function of the item type to match against
- `options.inside: `Rectangle`` — the rectangle in which the items need to be fully contained
- `options.overlapping: `Rectangle`` — the rectangle with which the items need to at least partly overlap

#### Parameters:

- `options:` `Object`⟋`Function` — the criteria to match against

#### Returns:

- `Array of `Item` objects` — the list of matching descendant items

#### See also:

- ``matches(options)``

`getItem(match)`

Fetch the first descendant (child or child of child) of this item that matches the properties in the specified object. Extended matching is possible by providing a compare function or regular expression. Matching points, colors only work as a comparison of the full object, not partial matching (e.g. only providing the x- coordinate to match all points with that x-value). Partial matching does work for `item.data`. See `project.getItems(match)` for a selection of illustrated examples.

#### Parameters:

- `match:` `Object`⟋`Function` — the criteria to match against

#### Returns:

- ``Item`` — the first descendant item matching the given criteria
