Abstract

At least certain embodiments of the present disclosure include an environment with user interface software interacting with a software application to provide gesture operations for a display of a device. A method for operating through an application programming interface (API) in this environment includes transferring a scaling transform call. The gesture operations include performing a scaling transform such as a zoom in or zoom out in response to a user input having two or more input points. The gesture operations also include performing a rotation transform to rotate an image or view in response to a user input having two or more input points.

Claims

1. In an environment with a device having a display with multiple views and user interface software interacts with a software application, a method for operating through an application programming interface (API), comprising:

transferring a rotation transform call to determine a rotation transform for a view associated with a user input having a plurality of input points.

2. The method of claim 1, further comprising:

transferring a start rotation gesture call;

transferring a gesture rotation progress call; and

transferring a rotation gesture end call.

3. The method of claim 1, wherein the rotation transform comprises a minimum and maximum degree of rotation for associated minimum and maximum rotation views.

4. The method of claim 3, wherein the user input causes the view to temporarily rotate past a maximum degree of rotation prior to the view snapping back to the maximum degree of rotation.

5. The method of claim 1, wherein transferring the rotation transform call is either one of issuing, initiating, invoking and receiving the scaling transform call.

6. The method of claim 1, wherein the device is one of:

a data processing device, a portable device, a portable data processing device, a multi touch device, a multi touch portable device, a wireless device, and a cell phone.

7. A machine readable medium storing executable program instructions which when executed cause a data processing system to perform a method comprising:

transferring a rotation transform call to determine a rotation transform for a view associated with a user input having a plurality of input points.

8. The medium of claim 7, further comprising:

transferring a start rotation gesture call;

transferring a gesture rotation progress call; and

transferring a rotation gesture end call.

9. The medium of claim 7, wherein the rotation transform comprises a minimum and maximum degree of rotation for associated minimum and maximum rotation views.

10. The medium of claim 9, wherein the user input causes the view to temporarily rotate past a maximum degree of rotation prior to the view snapping back to the maximum degree of rotation.

11. The medium of claim 7, wherein transferring the rotation transform call is either one of issuing, initiating, invoking and receiving the scaling transform call.

12. The medium of claim 7 wherein the data processing system is one of:

a data processing device, a portable device, a portable data processing device, a multi touch device, a multi touch portable device, a wireless device, and a cell phone.

13. The medium of claim 7, wherein the rotation transform call is transferring through an application programming interface to determine a rotation transform for a view associated with a user input having a plurality of input points.

14. A platform for performing gesture operations, comprising:

a processing unit coupled to an input panel;

a memory coupled to the processor; and

one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the processing unit, the programs including;

instructions for transferring a rotation transform call through an application programming interface to determine a rotation transform for a view associated with a user input having a plurality of input points.

15. The platform of claim 14, wherein transferring the rotation transform call is either one of issuing, initiating, invoking or receiving the rotation transform call.

16. The platform of claim 14, wherein the rotation transform comprises a minimum and maximum degree of rotation for associated minimum and maximum rotation views.

17. The platform of claim 14, wherein the user input causes the view to temporarily rotate past a maximum degree of rotation prior to the view snapping back to the maximum degree of rotation.

18. A framework for performing scrolling operations, comprising:

a directory for storing one or more programs and associated resources, wherein the programs contain instructions that when executed provide an application programming interface to specify a rotation transform for a view associated with a user input having a plurality of input points.

19. The framework of claim 18, wherein the rotation transform comprises a minimum and maximum degree of rotation for associated minimum and maximum rotation views.

20. The framework of claim 18, wherein the user input causes the view to temporarily rotate past a maximum degree of rotation prior to the view snapping back to the maximum degree of rotation.
