It will also be appreciated that new templates created by the document template creator tool are also made available to the document template selector tool.
  • the document template selector tool is particularly useful when the user 224 is mainly interested in preparing a report as the Book-type Generation Modules 206 will retain, in the final created electronic document 226, the layout the user 224 employed when he was preparing the electronic document 226. Thus, the user 224 can concentrate on writing his report, without worrying whether there will be content alignment changes in the final created electronic document.
  • the document template selector tool can also provide a step-by-step guide to assist the user 224 in aligning and formatting the contents on each page of the electronic document 226 to be created. For instance, a "poem" template will guide the user 224 to create a book of poems, while a "recipe" template will guide the user 224 to easily create a cooking manual.
  • the document layout tool of the Book-type Generation Modules 206 allows the user 224 to customise pre-defined templates.
  • the user 224 can also use the Book-type Generation Modules 206 to make further customisations, such as the manner in which each page of the electronic document 226 proceeds to the next.

  • Hierarchies, dynamic links and other intrinsic media properties are added, and certain original media properties are amended.
  • Hierarchies are priority levels that can be applied to an object, a group of objects, or even a portion of an object so that different portions of the same object can have different hierarchies.
  • real-time media processing is made more efficient.
  • a dynamic interrelationship can be created between the different objects concerned. For instance, when a higher hierarchy is assigned to a first image and a lower hierarchy is assigned to a second image, moving the first image will cause a corresponding movement to the second image. However, moving the second image will not cause a movement in the first image.
  • Dynamic links serve as signals embedded in an object in the electronic that once activated cause a separate pre-programmed event to occur. Dynamic links are used by the Action and Event Management Modules 212 and will be described in greater detail with reference to reference to Figs. 12 to 15.
  • Intrinsic media properties refer to properties added into the original data structure of objects imported into the electronic document.
  • an animated 2D media file may have a "speed" property included as part of its new data structure, so that when the animated media file is embedded into the electronic document, its animation speed can be controlled by its new intrinsic "speed” property.
  • Loading and Formatting Modules 208 amend original media properties, when an electronic picture file with data format "bmp" is loaded by the electronic authoring tool 200 and passed through the Loading and Formatting Modules 208, it no longer remains as data format "bmp", but rather data with a texture format having surface modulation properties.
  • the Loading and Formatting Modules 208 of the electronic authoring tool 200 provides mechanisms for loading external media that include: electronic picture files with data format such as “jpg”, “bmp”, “png” and “gif ; text files with data formats such as “doc”, “pdf ', “xml”, “html”, “txt” and “rtf; video files with data formats such as “avi” and “mpg”; sound files with data formats such as “wav", "mp3” and “midi”; and
