Abstract

An electronic publication and methods and components thereof including a user interface. The electronic publication can be provided by e-mail or similar transmission add contains its own executable file for presentation of the publication without a user requiring a preloaded application software. The electronic publication addresses the processor for calculation and the operating system for increased functionality to minimize the size of the executable file and the publication as a whole. The publication contains a user interface incorporating a page-turn and provides a non-linear travel of the free edge of the tog page across a revealing page so as to imitate a substantially constant rotation of the page. The animation sequence throughout the page-turn is performed on the basis of actual elapsed time since commencement of the animation rather than at predetermined intervals so as to make the individual steps throughout the animation independent of the processor speed. The page-turn also incorporates a 3-dimensional representation by increasingly stretching the vertical axis of the rotating edge of the page as it approaches the central axis of rotation of the page.

Claims

1. An electronic publication comprising:

an executable application; and

a document for publication having a plurality of pages;

wherein the application and publication comprise a unitary file in assembly code to address a compatible processor directly and containing a plurality of commands to address sub-routines in a compatible operating system to provide a graphical output of the publication on a display screen.

2. An electronic publication as claimed in claim 1, wherein said hardware processor comprises a microprocessor in one of a computer and an Internet capable device.

4. An electronic publication as claimed in claim 1, wherein said operating system comprises a Microsoft Windows operating system.

5. An electronic publication as claimed in claim 4, wherein said application provides said publication with a page transition effect in the manner of an animation similar to the turning page of a print publication.

6. An electronic publication as claimed in claim 5, wherein said application addresses said Microsoft Windows operating system to perform the following steps:

requesting a repaint of the display screen;

calculating the elapsed time from initiation of the page-turn animation upon receiving an indication said Microsoft Windows operating system is ready to repaint the screen;

calculating the position of the turning page in accordance with the elapsed time;

instructing said Microsoft Windows operating system to repaint the display screen with a frame of said animation; and

requesting a further repaint of the display screen.

7. An electronic publication as claimed in claim 6, wherein the turning page is stretched in a direction parallel to the axis of its rotation and compressed in a direction orthogonal to its axis of rotation and the quantity of stretch and compression is calculated in accordance with one of the position of the turning page, and said elapsed time, in a frame of said animation.

8. An electronic publication as claimed in claim 5, wherein at least one of an image and text on a turning page of said animation is calculated on a pixel by pixel basis by mapping pixels from a prior frame of said animation to corresponding positions on said turning page.

10. A method of providing an electronic publication as claimed in claim 8, wherein said application is in assembly code to address a compatible processor directly and containing a plurality of commands to address sub-routines in a compatible operating system to provide a graphical output of the publication on a display screen.

3. An electronic publication as claimed in claim 3, wherein said hardware processor comprises a PC compatible microprocessor.

9. A method of providing an electronic publication comprising:

producing an executable application;

producing a document for publication containing a plurality of pages; and

distributing said electronic publication as a unitary file comprising both said application and said document for publication;

wherein said application presents said electronic publication as a graphical output on a display screen including a page transition effect between a first page and a subsequent page in the form of an animation of a turning page.
