Description

WEB-BASED PRESENTATION EDITING APPARATUS FOR QUICK LOADING OF PRESENTATION DOCUMENTS THROUGH BROWSER AND OPERATING METHOD THEREOF}

The present invention relates to a web-based presentation editing apparatus capable of quickly loading a presentation document on a browser and a method of operating the same.

Recently, as computers, smartphones, tablet PCs, and the like are widely used, various kinds of electronic document-related programs for reading, creating, and editing electronic documents using such terminal devices have been released.

Such electronic document related programs include word processors that support the creation and editing of basic documents, data entry, arithmetic operations, spreadsheets to assist data management, and presentation programs to assist presenters.

In general, the presentation document, as shown in FIG. 1, has a master slide 110 that defines a background template which is preset as commonly applicable to a plurality of pages constituting the document, and is common to the plurality of pages. It consists of layout slides 120 defining at least one layout preset as applicable and slides containing individual content of each of the plurality of pages.

In relation to this, when a presentation document corresponding to a total of five pages exists, the master slide 110 is applied as a common background template to the five page document, and the layout slides 120 shown in FIG. ), A layout slide having any one of the layouts is additionally applied, and at the same time, slides including individual contents such as figures, pictures, and texts input by the user are additionally applied to each of the five pages.

In addition, when a user creates a presentation document, the user may determine a specific layout slide among the layout slides 120 in order to determine a master slide 110 to be commonly applied to the document and then create a page having a desired layout for each page. When the master slide and the layout slide are determined in this way, the user can create slides corresponding to each page by directly inserting individual contents such as figures, pictures, and text for each page.

As a result, the presentation document forms one page by combining the master slide, the layout slide, and the slide. The form of the master slide, the layout slide, and the page in which the slide is combined is shown in FIG. 2.

Relatedly, a master slide, a layout slide, and a slide are all composed of two layers, a background layer for representing a background such as the color of each slide, and an object layer for displaying an inserted object for each slide. have.

Accordingly, the presentation document forms a single page by stacking a background layer and an object layer of a master slide, a background layer and an object layer of a layout slide, a background layer and an object layer of a slide, as illustrated in FIG. 2. .

In more detail, as shown in FIG. 2, the presentation document includes the lower layer from the background layer of the master slide, the background layer of the layout slide, the background layer of the slide, the object layer of the master slide, the object layer of the layout slide, Object layers are sequentially stacked to form one page.

In the technique of loading an existing presentation document and displaying it on the screen, the background layer and object layer of the master slide corresponding to each page, the background layer and object layer of the layout slide, and the background layer of the slide are provided for each of a plurality of pages constituting the presentation document. After rendering all the object layers, the rendered layers for each page are stacked and displayed on the screen.

As a result, when the number of pages that make up a presentation document is large, the background layer and object layer of the master slide, the background layer and object layer of the layout slide, and the background layer and object layer of the slide are all rendered for each page. It took a lot of time before the document was loaded and displayed on the screen.

Recently, a web-based presentation document editing technology is introduced, which allows a presentation document to be displayed and edited through a browser. In the conventional web-based presentation document editing technology, when a presentation document is loaded in a browser, Likewise, the background layer and the object layer of the master slide, the background layer and the object layer of the layout slide, the background layer and the object layer of the slide are all rendered for each of the pages of the presentation document. Since the rendered layers are stacked and displayed on the screen, it takes a lot of time to load the presentation document.

For example, when a presentation document corresponding to 300 pages needs to be loaded in a browser, a technique of loading a presentation document through an existing browser is a master slide, a layout slide, and a slide for each of the 300 pages, as shown in FIG. Configure the Document Object Model (DOM) 310 for the background layer of the object and the DOM 320 for the object layers of the master slide, layout slide, and slide, and then create the DOM ( Based on the 310 and the DOM 320 of the object layer, the master slide, the layout slide, and the background layer of the master slide, the layout slide, and the object layer of the master slide, the layout slide, and the slide are all rendered for each of 300 pages.

The demand for technology is increasing recently because web-based presentation editing technology enables a large number of users to co-edit a document regardless of time and place. As the use of web-based presentation editing technology increases, a study on a technique for enabling fast loading when a presentation document is loaded in a browser is required.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. This description is not intended to limit the invention to the specific embodiments, it should be understood to include all changes, equivalents, and substitutes included in the spirit and scope of the invention. In describing the drawings, similar reference numerals are used for similar components, and unless otherwise defined, all terms used in the present specification, including technical or scientific terms, may be used in the art to which the present invention pertains. It has the same meaning as is commonly understood by someone who has it.

4 is a diagram illustrating a structure of a web-based presentation editing apparatus capable of quickly loading a presentation document through a browser according to an embodiment of the present invention.

Referring to FIG. 4, the web-based presentation editing apparatus 410 capable of quickly loading a presentation document through a browser according to an embodiment of the present invention includes a slide checker 411, a first renderer 412, and a first renderer 412. 2 includes a rendering unit 413 and a screen display processing unit 414.

The slide checking unit 411 may define a background template which is preset to be applicable to a plurality of pages constituting the presentation document from the presentation document when the load command of the presentation document is applied in the browser. Identify at least one layout slide that defines a slide and at least one layout that is preset as commonly applicable to the plurality of pages and a plurality of slides containing individual content of each of the plurality of pages do.

Here, as described above with reference to FIG. 1, the master slide may exist as one or more slides defining a preset background template that is commonly applicable to a plurality of pages. For example, if there is a presentation document corresponding to 10 pages, master slide 1 may be applied to pages 1 to 5 and master slide 2 may be applied to pages 6 to 10.

The layout slide refers to a slide that defines a predetermined layout that is commonly applicable to a plurality of pages under a specific master slide, as illustrated in FIG. 1, and the slide refers to a user on each of the plurality of pages. Means a slide for representing the inputted individual content.

In addition, the master slide, layout slide, and slides are all composed of two layers, a background layer for representing a background such as the color of each slide, and an object layer for displaying an inserted object for each slide. .

As such, when the at least one master slide, the at least one layout slide, and the plurality of slides are confirmed from the presentation document through the slide checker 411, the first renderer 412 may perform the at least one master. The background layer and the object layer of the slide and the background layer and the object layer of the at least one layout slide are rendered.

The second renderer 413 renders the background layer and the object layer of the plurality of slides one by one for the plurality of pages.

In this case, according to an embodiment of the present invention, the web-based presentation editing apparatus 410 capable of quickly loading a presentation document through a browser may further include a DOM constructing unit 415.

When the at least one master slide, the at least one layout slide, and the plurality of slides are identified from the presentation document, the DOM configuration unit 415 may determine a document object model for a background layer and an object layer of the at least one master slide. (Document Object Model: DOM), a DOM for the background layer and the object layer of the at least one layout slide, a DOM for the background layer and the object layer of the plurality of slides.

For example, if the presentation document is composed of 300 pages in total, and is composed of 2 master slides, 10 layout slides, and 300 slides corresponding to 300 pages, the DOM configuration unit 415 is illustrated in FIG. As shown in the figure, the DOM 511 for the background layer of the two master slides and the DOM 512 for the object layer can be configured, and the DOM 521 and the object layer for the background layer of the ten layout slides. The DOM 522 may be configured, and the DOM 531 for the background layer of the 300 slides and the DOM 532 for the object layer may be configured.

In this case, the first renderer 412 renders the background layer and the object layer of the at least one master slide based on the DOM of the background layer and the object layer of the at least one master slide, and the at least one layout slide. The background layer and the object layer of the at least one layout slide may be rendered based on the DOM of the background layer and the object layer.

The second renderer 413 may render the background layer and the object layer of the plurality of slides one by one for each of the plurality of pages based on the DOM of the background layer and the object layer of the plurality of slides.

When the first page is selected as a page to be displayed on the screen through the browser among the plurality of pages, the screen display processing unit 414 renders the background layer, the object layer, and the rendering of the at least one master slide. A background layer and an object layer of the first master slide corresponding to the first page among the background layer and the object layer of the completed at least one layout slide, the background layer and the object layer of the plurality of rendered slides, and a first layout The background layer and the object layer of the slide, the background layer and the object layer of the first slide are stacked and displayed on the screen.

In this case, according to an exemplary embodiment of the present invention, the screen display processing unit 413 may have a background layer of the first master slide and a background of the first layout slide from a lower layer of the screen, as shown in the structure of the figure illustrated in FIG. 2. The radars are stacked on the screen by laminating a layer, a background layer of the first slide, an object layer of the first master slide, an object layer of the first layout slide, and an object layer of the first slide. The display of one page can be processed.

As a result, the web-based presentation editing apparatus 410 capable of quickly loading the presentation document through the browser according to the present invention, when a load command for the presentation document is applied on the browser, the at least one master slide constituting the presentation document. Renders the background layer and the object layer and the background layer and the object layer of at least one layout slide only once, and renders the background layer and the object layer of the slides corresponding to each page for each page. When a specific page is selected, the master slide, layout slide, background layer and object layer corresponding to the page are stacked and displayed on the screen. Compared to the traditional way of loading a presentation layer that renders both the background layer and the object layer for a slide, the number of renders can be reduced, resulting in faster document loading.

In this case, according to an embodiment of the present invention, the web-based presentation editing apparatus 410 capable of quickly loading a presentation document through a browser further includes a rendering checking unit 416 and a priority rendering processing event generating unit 417. can do.

The rendering checker 416 selects the first page as a page to be displayed on the screen through the browser among the plurality of pages by the user before the rendering of the background layer and the object layer of the plurality of slides is completed. In this case, it is determined whether rendering of the background layer and the object layer of the first slide corresponding to the first page among the plurality of slides is completed.

When the rendering processing event generator 417 determines that the rendering of the background layer and the object layer of the first slide is not completed, the rendering processing event generating unit 417 generates a priority rendering processing event for the background layer and the object layer of the first slide. Let's do it.

In this case, when the priority rendering process event occurs, the second rendering unit 413 stops rendering of the background layer and the object layer of the plurality of slides and preferentially renders the background layer and the object layer of the first slide. Can be processed.

When the background rendering and the object layer of the first slide are first rendered, the screen display processing unit 414 performs the background layer and the object layer and the first layout of the first master slide corresponding to the first page. The background layer and the object layer of the slide, the background layer and the object layer of the first slide may be stacked and displayed on the screen.

In relation to this, when a presentation document is loaded, the number of master slides and layout slides constituting the presentation document is limited regardless of the number of pages of the presentation document, while the slides for each page are numbered according to the number of pages. Can be a lot. Accordingly, the rendering of the background layer and the object layer for the master slide and the layout slide performed in the first renderer 412 is completed relatively quickly, but the background layer and the object for the slides performed in the second renderer 413 are relatively fast. Rendering a layer can take some time.

If the presentation document is composed of 300 pages, the rendering of the master slide and the layout slide is completed in the first rendering unit 412, while the slide corresponding to 1 to 20 pages in the second rendering unit 413 is completed. If the selection command is authorized to allow the user to display 30 pages of the document on the screen while the rendering is completed only for, the rendering of the background layer and the object layer for the slide corresponding to page 30 has not been performed yet. Therefore, the screen display processing unit 414 may not display a document corresponding to 30 pages on the screen.

In order to prevent such a problem, the rendering checker 416 may, when a selection command for displaying the first page on the screen is applied by the user, the background layer and the object layer of the first slide corresponding to the first page. You can check whether or not rendering has been completed. If the second rendering unit 413 determines that the rendering of the background layer and the object layer of the first slide is completed, the screen display processing unit 414 may perform the rendering of the first master slide, the first layout slide, The first page may be displayed on the screen by stacking the background layer and the object layer of the first slide.

However, if it is confirmed in the second rendering unit 413 that the rendering of the background layer and the object layer of the first slide has not yet been completed, the rendering processing event generator 417 firstly performs the background layer and the first layer of the first slide. The first rendering processing event may be generated for the object layer. In this case, the second rendering unit 413 stops rendering the background layer and the object layer of the plurality of slides in response to the first rendering processing event. First rendering of the background layer and the object layer of the first slide may be processed. Then, when the first rendering of the background layer and the object layer of the first slide is completed, the screen display processing unit 414 may perform the rendering of the first master slide, the first layout slide, the background layer of the first slide, and By stacking the object layers and displaying them on the screen, the display of the first page can be normally processed.

In this case, according to an embodiment of the present invention, when the presentation document is loaded, the second rendering unit 413 may apply a display command of a specific page by the user before rendering of slides corresponding to each page is completed. The rendering order determining unit 418 and the rendering processor 419 may be included as a configuration for allowing the page to be normally displayed on the screen.

The rendering order determining unit 418 counts the number of individual content objects inserted in each of the plurality of slides, and determines the rendering order for each of the plurality of slides in the order of decreasing number of individual content objects.

Here, the individual content object inserted in each of the slides refers to a content object such as a figure, a picture, or a text inserted by a presentation document editor on each page. The content object is a master that constitutes each page. It exists on a slide, a layout slide, and a slide. In this case, the rendering sequence determination unit 418 may count the number of individual content objects inserted in each of the plurality of slides.

If the presentation document is composed of 300 pages, the plurality of slides will be 300. At this time, the rendering sequence determination unit 418 counts the number of individual content objects inserted in each of the 300 slides. The rendering order number for each of the 300 slides may be determined in the order of the smallest number of individual content objects.

The rendering processor 419 sequentially processes one background layer and one object layer for each of the plurality of slides according to the rendering order determined for each of the plurality of slides.

That is, since the smaller the number of individual content objects inserted in the slide, the less time the rendering process takes. Therefore, the rendering processor 419 may first complete the rendering process from slides in which the individual content objects are inserted. Therefore, when a user applies a screen display command for a specific page, even if rendering of the plurality of slides is not completed, if the rendering of the slide corresponding to the page is completed first, the screen display processing unit ( 414 may preferentially display the page on the screen, so that the user can normally view the page selected by the user.
