• step 2310 the processing unit then sets the presentation width of the second computer graphics 54 associated with the foreground to approximately zero.
• the processing unit now iteratively enlarges the displayed width of the sixth computer graphics 52 in the right foreground 34 with variable step size and speed, and increasingly obscures the view of the second computer graphic 54 positioned in the right background 32, as shown in FIG 18, until the sixth
• a new layout record is requested or created locally, or the existing layout record is updated with new computer graphics such that the pages exposed as a result of the page flip operation (51 and 52 after backward scrolling, or 55 and 56 after scrolling forward) form the first and second computer graphics of the updated layout data record, and the respective following page pair of page sequence, the third and fourth, as well as the respective preceding page pair of page sequence form the fifth and sixth computer graphics of the updated layout data record, after which the reload method can be reapplied.
• the method can be used to display only one of the two layout areas, in particular for page-through. If the number or order of the pages contained in the digital document does not correspond to the present schema of three consecutive pairs of pages, then in digital format Document missing pages will be replaced by transparent graphics. In order to achieve a faster page layout, a graphic preload can be additionally started after the loading of each page in order to advance the next required graphics into the buffer of the WWW browser.
• the proposed system animates the page-turning process in digital documents represented by computer graphics, and due to the special assignment of the computer graphics to a layout data set, allows the animation process to be realized by computation and memory-efficient assignment and attribute setting operations, which can be implemented on a wide variety of technical platforms with little technical effort.
• embodiments may include both systems in which the animation functions and the data processing necessary therefor are integrated on a user device (described with reference to FIG. 1 and the method description) and further those in which the data rendering functions required for the animation are located on a user-remote system component, such as a server, while the animation functions are implemented on the user device, in this case a client, with reference to FIG and the procedure description).
• the animation and data rendering functionalities may, in an implementation as described with reference to FIG. 1, be implemented in software that includes instructions describing the features of the implemented method, and which is contained in the memory 114 (not shown).
• the data rendering functionality may be implemented in a data rendering software that supports the data processing functionality
• the software may be executed on a general-purpose processor while relying on common Internet technologies, such as the functions provided by a web browser or web server, and commands (eg, JavaScript, PHP). To fall back on.
• the devices 1 and 3 can each be implemented by means of a web browser installed on a stationary or mobile computer, which receives the page graphics to be displayed together with JavaScript commands for the animation from a web server.
• the above-described software can thus be brought into the memory of the device 1 and 3 and executed there when the WWW page is displayed by the browser.
• the data preparation (data editing software) and animation (animation software ) and the page graphics to be displayed are sent from a web server and received by a web client, and the layout Data structure in the web client built (dynamic DOM structure) and brought to the animated presentation.
• the finished layout data structure in the form of an HTML or XML or SGML file, the commands for animation (animation software) and the page graphics to be displayed are sent from a web server and through a web Client received and brought to the animated presentation.
• the present system can operate with a variety of different storage and delivery types of graphic digital documents.
• the page graphics may be stored in a database as a result of graphics pages in an Adobe PDF document, or other types of documents having graphics encoded pages, or generated dynamically.
• the page graphics may also be stored in a file system provided with appropriate file and / or directory structures.
• a WWW browser which calls a corresponding WWW page, be populated with the layout data structure in the form of an HTML page and associated graphics, and the browser can in the same way with suitable for the execution of the animation process scripting programs, such as JavaScript to be set up.
