Benefits of technology

The technical effect that this patented technology can be used for carrying out various types of meetings or collaborative projects on paper-based materials such as PowerPoint® slides are described by these inventors.

Problems solved by technology

The technical problem addressed in this patented solution relates to improving the load time on an opened presentation file when there are complicated items like images that may slow down its processing. Additionally, users who want immediate access to their pages have difficulty navigating quickly due to limited screen space available during scrolling displays.

specific Embodiment approach

[0025] figure 2 A general flowchart of the improved method for presentation document loading is presented. The specific implementation mode that the present invention adopts is as follows:

[0026] (1) Import the document first (step S1);

[0027] (2) Judging the document, and comparing it with the presentation filter to determine whether it is a document corresponding to the presentation (step S2);

[0028] (3) If it is a presentation document, open up a new thread (step S3), the main way to open the thread is as follows: OpenOffice creates multi-threaded functions for different platforms and repackages them, which are defined in the class osl::Thread , before loading the slideshow document, by inheriting the above class, using the virtual function void run() of this class to throw a sub-thread, while creating the sub-thread, it is actually for each thread in TLS (Thread Local Storage ) to create their own global variables to occupy memory blocks to prevent data exception...

Abstract

The invention discloses a method for asynchronously loading power point documents, which is a thread management method for loading the power point documents by using an impress component in OpenOffice. The method comprises the following steps of: 1, introducing a document; 2, judging the document, contrasting through a power point filter and judging whether the document is a corresponding power point document; 3, if the document is the power point document, developing a new document resolving sub thread; and 4, after the document resolving sub thread resolves a document template, controlling to make a master thread execute continuously through a function so as to build and display a power point module view framework, and controlling the continuous interaction between the master thread for the view displaying and the resolving sub thread. When a large power point document is uploaded, a remarkable effect is achieved.
