animate: true | { delay: num, easing: string } | false

Animate transformations. Works best in combination with apply() (see the functions section below).

Default: { delay: 700, easing: 'linear' }

attrs: { fill: hex, stroke: hex }

Sets the attributes of the handles.

Default: { fill: '#fff', stroke: '#000' }

`customCorners: { size: num, distance: num, corners: [ { action: string: image: string }, ... ] } | false

Specify custom images and events for corner handles.

The corners array should contain 4 objects, one for each corner starting top left going clockwise.

Valid actions: drag, rotate, scale or a custom string. Actions are emitted as events in the callback.

Default: false

boundary: { x: int, y: int, width: int, height: int } | false

Limits the drag area of the handles.

Default: dimensions of the paper

distance: num

Sets the distance of the handles from the center of the element (num times radius).

Default: 1.3

drag: true | [ 'center', 'self' ] | false

Enables/disables dragging.

Default: [ 'center', 'self' ]

draw: [ 'bbox', 'circle' ]

Additional elements to draw.

Default: false

keepRatio: true | [ 'axisX', 'axisY', 'bboxCorners', 'bboxSides' ] | false

Scale axes together or individually.

Default: false

range: { rotate: [ num, num ], scale: [ num, num ] }

Limit the range of transformation.

Default: { rotate: [ -180, 180 ], scale: [ 0, 99999 ] }

rotate: true | [ 'axisX', 'axisY', 'self' ]|false

Enables/disables rotating.

Default: [ 'axisX', 'axisY' ]

scale: true | [ 'axisX', 'axisY', 'bboxCorners', 'bboxSides' ] | false

Enables/disables scaling.

Default: [ 'axisX', 'axisY', 'bboxCorners', 'bboxSides' ]

snap: { rotate: num, scale: num, drag: num }:

Snap transformations to num degrees (rotate) or pixels (scale, drag).

Default: { rotate: 0, scale: 0, drag: 0 }

snapDist: { rotate: num, scale: num, drag: num }

Snap distance in degrees (rotate) or pixels (scale, drag).

Default: { rotate: 0, scale: 0, drag: 7 }

size: num | { axes: num, bboxCorners: num, bboxSides: num, center: num }

Sets the radius of the handles in pixels.

Default: 5


A callback function can be specified to capture changes and events.



Programmatically apply transformations (see the example above).

hideHandles( opts )

Removes handles but keeps values set by the plugin in memory. By default removes all drag events from the elements. If you'd like to keep then while the handles are hidden, pass {undrag: false} to hideHandles().


Shows handles hidden with hideHandles().

setOpts( object, function )

Update options and callback.


Removes handles and deletes all values set by the plugin.


Updates handles to reflect the element's transformations.
