Abstract: At a multifunction device with a display and a touch-sensitive surface, a plurality of objects are displayed on the display. The plurality of objects have a first layer order. A first contact is detected at a location on the touch-sensitive surface that corresponds to a location of a respective object of the plurality of objects. While detecting the first contact, a gesture that includes a second contact is detected on the touch-sensitive surface. In response to detecting the gesture, the plurality of objects are reordered in accordance with the gesture to create a second layer order that is different from the first layer order. In some embodiments, the position of the respective object within the first order is different from the position of the respective object within the second order.

Abstract: Alignment guides configured for velocity-sensitive behavior are disclosed. In one embodiment, during a user interface element move gesture, the gesture velocity is determined, and while moving the user interface element during the gesture, the user interface operates in a first or a second state with respect to displaying alignment guides. When the velocity of the user gesture exceeds a predefined velocity threshold, the display of the user interface is maintained in the first state, which does not include visibly displaying alignment guides. When the velocity of the user gesture is less than the predefined velocity threshold, the user interface is displayed in a second state that includes visibly displaying one or more alignment guides. In some embodiments, gesture velocity is used to set alignment guide attraction strength.

Abstract: Systems and methods are disclosed for an image editing process on an electronic device that uses an image mask to edit an image object. The image editing process may include an image mask overlying the image object and having a frame and an aperture. The image editing process may crop the image object based on the portions of the image object overlaid by the mask frame and the mask aperture. The image object and the image mask may be separately selected and manipulated by selecting different regions of the image object or the image mask. Additionally, a user may resize the image object by moving a slider, such as by touching and moving a slider knob along an axis.

Abstract: Systems and methods are disclosed for a z-order editing process that adjusts the z-ordering of selected objects displayed on a user interface. The z-ordering editing process may include identifying one or more selected objects and providing a z-ordering editing mode having an interactive graphical adjustment tool. The interactive graphical adjustment tool may receive user inputs indicating a desired direction for z-ordering adjustment. Changes in the z-ordering of the selected objects may be applied and dynamically previewed before ultimately being accepted by a user.
