摘要：Character morphing between slides of a presentation is disclosed. In certain implementations, Characters with varying styles within separate slides are matched and can be animated during slide transitions using distance field morphing. In certain embodiments, this involves matching characters on both an outgoing and incoming slide and providing a morphing process in order to smoothly transition from the outgoing slide to the incoming slide. Additionally, different techniques may be provided along with the distance field morph to further improve the slide transition process.

主权项：1. A non-transitory, tangible computer-readable medium having instructions stored thereon, wherein the instructions, when executed by a processor cause acts to be performed comprising: analyzing an outgoing slide and an incoming slide of a slideshow presentation to identify one or more text characters on each of the outgoing slide and the incoming slide; performing a matching operation on the identified text characters to identify one or more pairs of matched text characters, each matched text character pair comprising a matched text character on the outgoing slide and a corresponding matched text character on the incoming slide; determining whether the matched text character on the outgoing slide and the corresponding matched text character on the incoming slide differ in character style; creating a distance field of an outline of the matched text character on the outgoing slide and a distance field of the corresponding matched text character on the incoming slide upon a finding of a difference in character style; and gradually morphing the distance field of the outline of the matched text character of the outgoing slide to the distance field of the outline of the corresponding matched text character on the incoming slide to generate a transitional animation that is executed when transitioning from the outgoing slide to the incoming slide.
