Description

An electronic device capable of quickly converting and loading annotations inserted in a PDF document into an editable format in an application editing tool and its operation method FORMAT EDITABLE BY THE APPLICATION EDITING TOOLS AND THEN LOAD THE ANNOTATIONS, AND THE OPERATING METHOD THEREOF}

The present invention relates to an electronic device capable of quickly converting and loading annotations inserted in a PDF document into an editable format in an application editing tool, and an operation method thereof.

PDF (Portable Document Format) documents are widely used by users because of their high compatibility with most operating systems and the fact that fonts, images, graphics, and document types of the original document can be maintained as they are. .

In this regard, recently, as portable terminals such as smart phones and tablet PCs are popular, application editing tools that support viewing and editing of documents in the portable terminals have appeared. These application editing tools support the import of a PDF document within the editing tool, so that the user can view or edit the PDF document using the application editing tool.

In general, a user creating a PDF document often inserts annotations into pages constituting the PDF document, as shown in FIG. 2 , in order to emphasize important content.

Application editing tools released on the market provide an annotation editing function to support users to edit annotations in a variety of formats in addition to the formats supported by the PDF-specific editing tool itself in PDF documents with annotations inserted. There are many cases. For example, if an annotation with a blue underline is inserted in a PDF document, and the available formats are limited to use only black, blue, and red as the color of the underline in the PDF editing tool, the application editing tool In many cases, it supports more diverse formatting, such as green or orange as the color of the underline.

In this way, in order to support changing the annotations inserted in the PDF document into more diverse formats in the application editing tool, the application editing tool, when the PDF document is imported, in the process of loading the PDF document, inserts into the PDF document After converting the annotation data into its own format designed to be editable in the application editing tool, it loads the annotations inserted into the PDF document in the converted proprietary format and displays them on the screen.

In this regard, in the process of loading a PDF document in which annotations are inserted, existing application editing tools convert all the pages constituting the PDF document to convert the annotation data into its own format, and construct each page. It was configured to search annotation data from data one by one. For this reason, when a PDF document with annotations is loaded through an existing application editing tool in an electronic device, there is a problem in that a lot of resources and time are consumed in loading the document.

If, when loading a PDF document with annotations inserted, it is first checked which page the annotations are inserted in, and only for the pages identified as having annotations inserted, the annotation data is added from the data constituting each page. If you can perform a search for PDF files, you will be able to minimize the resources and time required to load PDF documents through application editing tools.

The present invention proposes an electronic device capable of quickly converting and loading annotations inserted in a PDF document into an editable format in an application editing tool and an operating method thereof, so that the annotations are included in the electronic device through the application editing tool. We want to help minimize the resources and time required to load a PDF document that is available.

Referring to FIG. 1 , the electronic device 110 includes a page checking unit 111 and a page loading unit 112 .

The page confirmation unit 111 imports a document file for a first PDF (Portable Document Format) document composed of a plurality of pages through a preset application editing tool installed in the electronic device 110. When an event occurs, metadata constituting the first PDF document is checked to determine a page in which an annotation is inserted among the plurality of pages constituting the first PDF document.

Here, the meta data includes positional information on insertion points on the plurality of pages for annotations inserted into the first PDF document.

In general, PDF documents created according to the PDF document format standard include metadata that defines the format information of the PDF document. There may be information such as the table of contents of the document and the location information of annotations inserted into the PDF document.

Accordingly, the page checking unit 111 configures the first PDF document when an import event for importing a document file for the first PDF document occurs through the application editing tool installed in the electronic device 110. It is possible to check a page in which an annotation is inserted among a plurality of pages constituting the first PDF document by checking meta data of the first PDF document.

For example, a document file for 'PDF document 1' consisting of 'page 1, page 2, page 2, page 3, page 4, and page 5' is created through a preset application editing tool installed in the electronic device 110. Assume that an import event for importing occurs.

Here, among 'page 1, page 2, page 3, page 4, and page 5', it is assumed that 'page 1, page 3, page 4' does not have an annotation inserted, and 'page 2' shows the picture shown in FIG. Similarly, it is assumed that 'annotations 1, 2, and 3' are inserted, and 'page 5' has 'annotations 4 and 5' inserted as shown in FIG. 3 .

Then, the page verification unit 111 checks the meta data constituting 'PDF document 1' and selects 'page 1, page 2, page 3, page 4, and page 5' where the annotation is inserted, and 'page 2 , it can be confirmed that page 5' exists.

In this way, if it is confirmed by the page checking unit 111 that there is at least one page among the plurality of pages into which an annotation is inserted, the page loading unit 112 loads the at least one of the plurality of pages. For pages other than one page, the remaining pages are loaded without performing a search for annotation data in page data constituting each of the remaining pages, and for the at least one page, the at least one After searching for annotation data in page data constituting each page, the data format of each of the searched annotation data is converted into a first format designated in advance so as to be editable in the application editing tool, together with the at least one page. , The plurality of pages are loaded by loading annotations inserted into each of the at least one page.

In relation to this, as in the above example, it is confirmed that only 'page 2 and page 5' of 'page 1, page 2, page 3, page 4, and page 5' have annotations inserted by the page confirmation unit 111. In this case, for 'page 1, page 3, and page 4', the page loader 112 proceeds to load 'page 1, page 3, and page 4' without performing a search for annotation data from each page data. And, for 'page 2 and page 5', a search is performed for annotation data from each page data, and the data format of each searched annotation data is converted into a first format designated in advance to be editable in the application editing tool. Then, along with 'page 2, page 5', you can load the annotations inserted into each page.

At this time, according to one embodiment of the present invention, the page load unit 112 is a specific configuration for loading each of the plurality of pages, and includes a table creation unit 113, a command confirmation unit 114, and a first load processing unit. (115) and a second load processing unit (116).

The table creation unit 113 is a page in which an annotation is inserted among the plurality of pages by the page checking unit 111, and if it is confirmed that the at least one page exists, the page number of each of the at least one page. and a command table in which trigger commands instructing to search for annotation data in page data constituting each page are recorded in correspondence with each other.

For example, as in the foregoing example, by the page checking unit 111, 'page 1, page 2, page 2, page 3, page 4, and page 5' are selected as 'page 2, page 5' to which annotations are inserted. Assume that 5' is confirmed to exist.

Then, the table creation unit 113 sends a trigger command instructing search for annotation data in page numbers '2 and 5' of 'page 2 and page 5' and page data constituting each page. A command table recorded in association with each other can be generated as shown in Table 1 below.

page number trigger command 2 trigger command 2 5 trigger command 5

In this way, when the command table is generated by the table creation unit 113, the command checking unit 114 refers to the command table when loading each of the plurality of pages, so that a load target is displayed on the command table. It is checked whether the page number of each page and the corresponding trigger command are recorded.

The first load processing unit 115, among the plurality of pages, when a first page on which a page number and a corresponding trigger command are not recorded on the command table is loaded, the page data constituting the first page is loaded. The first page is loaded based on the page data constituting the first page without performing a search for annotation data.

The second load processing unit 116, among the plurality of pages, when a second page in which a page number and a trigger command corresponding thereto are recorded on the command table is loaded, in page data constituting the second page, After searching for annotation data and identifying at least one annotation data from the page data constituting the second page, based on the remaining data except for the at least one annotation data among the data constituting the second page , After loading only the page from which annotations are excluded from the second page, and converting the data format of the at least one annotation data into the first format, the at least one annotation data converted to the first format As a basis, the annotations inserted in the second page are loaded so that the annotations inserted in the second page can be displayed on the second page in the first format.

Hereinafter, operations of the command confirmation unit 114, the first load processing unit 115, and the second load processing unit 116 will be described in detail by way of example.

First, as in the above example, assume that the command table shown in Table 1 is created by the table generating unit 113.

At this time, if 'page 1' among 'page 1, page 2, page 3, page 4, and page 5' is loaded, the command checking unit 114 displays 'page 1' on the command table as shown in Table 1 above. It can be confirmed that the page number '1' and the corresponding trigger command are not recorded.

Then, the first load processing unit 115 loads 'Page 1' based on the page data constituting 'Page 1' without performing a search for annotation data in the page data constituting 'Page 1'. can do.

After that, if 'page 2' among 'page 1, page 2, page 3, page 4, and page 5' is loaded, the command checking unit 114 displays 'page 2' on the command table as shown in Table 1 above. It can be confirmed that '2', which is the page number of ',' and 'trigger command 2' corresponding thereto are recorded.

Then, the second load processing unit 116 may perform a search for annotation data in the page data constituting 'page 2' and check at least one piece of annotation data from the page data constituting 'page 2'.

In this regard, as in the above example, when it is assumed that 'annotation 1, annotation 2, and annotation 3' are inserted in 'page 2' as shown in FIG. From the page data constituting 'Page 2', a search is performed for annotation data in the page data constituting 'Page 2', 'Annotation data 1, Annotation data', each of 'Comment 1, Annotation 2, and Annotation 3'. 2, comment data 3' can be checked.

Then, the second load processing unit 116 selects 'annotation 1,' 'annotation 1, After loading only the pages excluding Annotation 2 and Annotation 3, and converting the data formats of 'Annotation Data 1, Annotation Data 2, and Annotation Data 3' into the first format, the 'converted to the first format' Based on annotation data 1, annotation data 2, and annotation data 3, 'annotation 1, annotation 2, and annotation 3' can be displayed on 'page 2' in the first format, so that 'annotation 1, annotation 2, and annotation 3' are displayed. ' can be loaded.

By repeating this process, the page loader 112 can load 'page 1, page 2, page 3, page 4, and page 5' respectively.

Also, according to one embodiment of the present invention, the electronic device 110 may further include a display unit 117 .

After the plurality of pages are loaded by the page loader 112, the display unit 117 displays a display command for displaying a third page, which is any one of the at least one page, on the screen by the user 130. When this is applied, the third page is displayed on the screen, and the annotations inserted in the third page are overlapped and displayed on the upper layer of the third page being displayed on the screen.

For example, according to the above-described example, the page loader 112 determines that 'page 1, page 2, page 3, page 4, and page 5' have been loaded, and then, by the user 130, ' When it is assumed that the display command for displaying page 2' is applied on the screen, the display unit 117 displays 'page 2' on the screen and simultaneously displays 'annotations 1, 2, and 3' on the screen. It can be displayed by overlapping it on the upper layer of 'Page 2' being displayed.

Also, according to one embodiment of the present invention, the electronic device 110 may further include a file generator 118.

After the plurality of pages are loaded by the page loader 112 and editing of the annotations inserted into the at least one page is performed by the user 130, the file creation unit 118 performs the editing of the at least one page. When an export event for exporting a document file for the first PDF document occurs through an application editing tool, the PDF document supports the data format of annotation data for annotations inserted into each of the at least one page. After re-converting to a data format for the first PDF document, a document file for the first PDF document is created.

For example, according to the above-described example, it is assumed that 'page 1, page 2, page 3, page 4, and page 5' constituting 'PDF document 1' have been loaded by the page loader 112, and the user 130 ), after editing of 'Annotation 1, Annotation 2, Annotation 3, Annotation 4, and Annotation 5' is performed, an export event for exporting a document file for 'PDF document 1' through the application editing tool is generated. If it is said to have occurred, the file creation unit 118 reconverts the data format of the annotation data for 'Annotation 1, Note 2, Note 3, Note 4, and Note 5' into a data format supported by the PDF document, and then ' A document file for 'PDF document 1' can be created.

In addition, according to an embodiment of the present invention, the electronic device 110 may further include a hiding processing unit 119, an annotation display unit 120, and an unhidden unit 121.

After the plurality of pages are loaded by the page loader 112, the hiding processor 119 applies a command to hide annotations inserted into the at least one page by the user 130. If so, the annotations inserted in the at least one page are hidden.

The annotation display unit 120 is in a state in which a fourth page, which is any one of the at least one page, is displayed on the screen after the annotation inserted into the at least one page is hidden by the hiding processing unit 119. , When a pointing input pointing to a first point within a preset separation distance from any one of the first annotations inserted in the fourth page is generated by the user 130, the first annotation is displayed for a preset display time. while temporarily displayed on the screen, and when the display time elapses, processing is performed so that the first annotation disappears in a fade-out form.

After the first annotation is temporarily displayed on the screen by the annotation display unit 120, before the display time elapses, the unhiding unit 121 is within the distance from the first annotation by the user 130. If the pointing input is additionally generated, the hiding process for the first annotation is canceled so that the first annotation can be continuously displayed on the screen.

Hereinafter, operations of the hiding processing unit 119, the annotation display unit 120, and the hiding canceling unit 121 will be described in detail, for example.

First, according to the above example, the page loader 112 assumes that 'page 1, page 2, page 3, page 4, and page 5' have been loaded, and then, by the user 130, ' If it is assumed that the command to hide annotations for hiding annotation 1, annotation 2, annotation 3, annotation 4, and annotation 5 is authorized, the hiding processing unit 119 displays “comment 1, annotation 2, annotation 3, annotation 4, annotation 5”. ' can be hidden to prevent it from being displayed on the screen.

After that, as shown in FIG. 4 , in a state where 'page 5' is displayed on the screen, a first point 410 within a preset separation distance from 'annotation 5' by the user 130 When it is assumed that a pointing input pointing to is generated, the annotation display unit 120 may temporarily display 'annotation 5' on the screen for a preset display time, as shown in FIG. 5 .

Here, the pointing input means an input applied through a pointer of an input device such as a mouse or a touch input generated according to a user's touch.

At this time, when the preset display time is '10 seconds', the annotation display unit 120 displays 'annotation 5' in a fade-out form when '10 seconds' elapse after 'annotation 5' is temporarily displayed on the screen. It can be processed to disappear with .

However, after 'annotation 5' is temporarily displayed on the screen by the annotation display unit 120, before '10 seconds' elapses, as shown in FIG. 6, 'annotation 5' is displayed by the user 130 When it is assumed that a pointing input pointing to the second point 610 within the separation distance is additionally generated, the unhiding unit 121 displays 'Annotation 5' so that 'Annotation 5' can be continuously displayed on the screen. You can cancel the hiding process for .
