Fixed layout electronic publications

According to some embodiments, techniques are described herein to assist a publisher to create fixed layout pages of an electronic publication. The techniques are useful for creating cookbooks, travel books, photography books, children's books, other “illustrated books”, or any other electronic publication where a fixed layout for at least some of the pages of the electronic publication is desirable. With the techniques, the publisher may embed fonts, select particular fonts and font sizes, assign visual content to fixed layout pages, and precisely position visual content at fixed positions on fixed layout pages. A scaling mechanism for an electronic reader device is also disclosed for scaling fixed layout pages to fit the size of a display screen of the reader device while maintaining the aspect ratio and assignment of visual content to fixed layout pages specified by the publisher.

Benefit Claim

This application claims the benefit as a Continuation of application Ser. No. 13/172,479, filed Jun. 29, 2011 the entire contents of which is hereby incorporated by reference as if fully set forth herein, under 35 U.S.C. §120. The applicants hereby rescind any disclaimer of claim scope in the parent application(s) or the prosecution history thereof and advise the USPTO that the claims in this application may be broader than any claim in the parent application(s).


The present invention relates generally to electronic publishing, and more particularly, to publishing and rendering an electronic publication in a fixed layout.

Today, the world of electronic publications enjoys increasing consumer awareness spurred by the recent availability of consumer electronic reader devices, or e-reader devices, such as those commercially available from well-known companies such as Apple, Barnes and Noble, and Sony. Electronic publishing data format standards have been developed and are being developed to provide publishers with a standardized set of rules and instructions for publishing electronic publications for different e-reader device platforms. An example of such a standard is the Electronic Publication (EPUB) standard developed by the International Digital Publishing Forum (IDPF). A current release of the ePub standard, 2.0.1, is available online at

Current electronic publishing data format standards are designed for re-flowable content and do not inherently support fixed layouts. This means that e-reader devices following these standards move visual content (e.g., text and images) from one page to another as necessary to fit visual content to the size of the e-reader device display screen and according user preferences. For example, current standards allow users to change the font or font size of text to suit their preferences. As the font or font size changes, an e-reader device may re-flow text as necessary so that the width of a line of text is no longer than the width of the screen thereby preventing the user from having to scroll or pan horizontally to read lines of the book. This may also result in visual content on a page re-flowing to the previous or next page or visual content on the previous or next pages re-flowing to a currently displayed page. Further, to mimic the behavior of actual physical books, many e-reader devices present visual content on pages that are displayed entirely on the screen of the e-reader device so that the user is not required to scroll or pan vertically when reading. As a result, if the font or font size is changed by the user, visual content initially on one page may re-flow to another page.

The re-flowable behavior of current standards and current e-reader devices is generally acceptable to publishers when the electronic publication consists largely of text with few or no images or images that are to be presented inline within text. However, some publishers may wish to publish an electronic publication in which the layout of visual content is fixed on pages and does not re-flow inter-page. Cookbooks, travel books, photography books, children\'s books, and other image intensive books are examples of types of electronic publications where a fixed layout may be desirable.

One possible solution to creating a fixed layout electronic publication is to capture or create a digital image of each entire page. An e-reader device may then display each image to the reader. However, this solution is less than optimal because the text of the page captured in an image typically would not be available as text data to useful text-based capabilities of many e-reader devices such as searching, bookmarking, highlighting and passage sharing. Further, if the dimensions of an image are not proportional to the dimensions e-reader device display, the e-reader device may split the image over multiple pages resulting in an unappealing presentation of the publication.

Based on the foregoing, it is clearly desirable to help publishers create fixed layout electronic publications in which a fixed relationship between visual content and pages may be maintained in e-reader device displays and in which text content is available to the e-reader devices as text data. The present invention fulfills these and other needs.

FIG. 2 shows a hierarchical file system view of an example electronic publication according to some embodiments of the invention.

FIG. 3 shows a flowchart of a sample rendering operation according to some embodiments of the invention.

FIG. 4 shows a flowchart of a sample scaling operation according to some embodiments of the invention.



As used herein, the term “electronic reader device”, or just “e-reader device”, refers to a physical platform (hardware and software) on which electronic publications are rendered. Non-limiting examples of e-reader devices include desktop computers, laptop computers, tablet computers, mobile/smart phones, dedicated e-reader devices, or any other computing device capable of or configured for rending electronic publications.

As used herein, the term “publisher”, unless otherwise indicated, refers to any human creator of an electronic publication. For example, the publisher may be the copyright owner of the content of the publication or an agent creating the publication on behalf of the copyright owner.

As used herein, the term “reader”, unless otherwise indicated, means a human user of an e-reader device.
