Device, method, and graphical user interface for manipulating a user interface object

摘要

In some embodiments, an electronic device with a display and a touch-sensitive surface displays a user interface object. The device detects a first contact and a second contact concurrently on the touch-sensitive surface. The device determines which contact of the first contact and the second contact is a topmost contact, a bottommost contact, a leftmost contact, and a rightmost contact on the touch-sensitive surface. While continuing to detect the first contact and the second contact, the device detects movement of the first contact across the touch-sensitive surface, and concurrently moves two edges of the user interface object that correspond to the first contact in accordance with the detected movement of the first contact, including horizontally moving one of the two edges and vertically moving the other of the two edges.

1. A method, comprising:
at a computing device with a display and a touch-sensitive surface:
simultaneously displaying on the display:
a digital image; anda cropping mask rectangle for the digital image, wherein the cropping mask rectangle has four edges comprising a top edge, a bottom edge, a left edge, and a right edge;while simultaneously displaying the digital image and the cropping mask rectangle, detecting a first contact and a second contact concurrently on the touch-sensitive surface;determining which contact of the first contact and the second contact is a topmost contact on the touch-sensitive surface;determining which contact of the first contact and the second contact is a leftmost contact on the touch-sensitive surface; andwhile continuing to detect the first contact and the second contact on the touch-sensitive surface:
detecting movement of the first contact across the touch-sensitive surface; andconcurrently moving on the display two edges of the cropping mask rectangle that correspond to the first contact in accordance with the detected movement of the first contact, including horizontally moving one of the two edges and vertically moving the other of the two edges, wherein movement of the two edges of the cropping mask on the display is independent of whether the first contact or the second contact are detected at a location on the touch-sensitive surface that corresponds to a location on the display of an edge of the cropping mask rectangle.
