Embodiment Construction

[0052]Various embodiments and aspects of the disclosure will be described with reference to details discussed below, and the accompanying drawings will illustrate the various embodiments. The following description and drawings are illustrative of the disclosure and are not to be construed as limiting the disclosure. Numerous specific details are described to provide a through understanding of various embodiments of the present disclosure. However, in certain instances, well-known or conventional details are not described in order to provide a concise discussion of embodiments of the present disclosure.

[0053]Some portions of the detailed descriptions which follow are presented in terms of algorithms which include operations on data stored within a computer memory. An algorithm is generally a self-consistent sequence of operations leading to a desired result. The operations typically require or involve physical manipulations of physical quantities. Usually, though not necessarily, the...

Abstract

At least certain embodiments of the present disclosure include an environment with user interface software interacting wit 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.

Description

FIELD OF THE DISCLOSURE[0001]This disclosure relates to application programming interfaces that provide gesture operations.COMPUTER PROGRAM LISTING[0002]A portion of the disclosure of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent & Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.[0003]Applicant has submitted herewith Computer Program Listings which are included as Appendix A, attached.BACKGROUND OF THE DISCLOSURE[0004]An API is a source code interface that a computer system or program library provides in order to support requests for services from a software application. An API is specified in terms of a programming language that can be interpretative or compiled when an application is built, rather than an explicit low level description of how data is l...
