FIG. 1 is a diagram illustrating a structure of an electronic terminal apparatus for copying and maintaining a shape of characters included in a PDF (Portable Document Format) document according to an embodiment of the present invention.

Referring to FIG. 1, an electronic terminal apparatus 110 for copying and maintaining a shape of a character included in a PDF document according to an embodiment of the present invention includes a glyph information extracting unit 111, a glyph information storing unit 112 ) And a character inserting section (113).

Here, the electronic terminal device 110 for copying and maintaining the shape of a character included in the PDF document according to an embodiment of the present invention may be an electronic terminal device for browsing, creating or editing an electronic document such as a desktop PC, a mobile terminal, a PDA, a notebook, Lt; RTI ID = 0.0 > microprocessor-based < / RTI >

When a copy command to the first electronic document is applied to at least one character among a plurality of characters included in the PDF document, the glyph information extracting unit 111 extracts a glyph map (Glyph Map) included in the PDF document, And extracts the glyph information for the at least one character from the glyph information.

Here, the glyph map refers to a mapping table storing glyph information indicating the shape of the plurality of characters to render and display the plurality of characters on the PDF document.

The glyph information storage unit 112 generates a glyph table for managing glyph information and stores the glyph information for the at least one character in the glyph table.

The character inserting unit 113 renders the shape of the at least one character based on the glyph information for the at least one character stored in the glyph table and stores the rendered at least one character on the first electronic document .

In this case, according to an embodiment of the present invention, the glyph map stores the respective glyph information stored in the glyph map and index keys for indexing the respective glyph information in association with each other, If there are two or more identical characters, the glyph information and the index key for the two or more identical characters may be stored in association with each other on the glyph map.

Each of the plurality of characters may be assigned an index key for indexing the glyph information corresponding to each of the plurality of characters in the glyph map.

At this time, the glyph information extracting unit 111 stores the index key corresponding to the same index key assigned to each of the at least one character from the glyph map based on the index key assigned to each of the at least one character At least one of the at least one glyph information may be extracted as the glyph information for the at least one character.

The glyph information storing unit 112 may store the at least one glyph information in the glyph table, and the character inserting unit 113 may store the at least one glyph information in the glyph table based on the at least one glyph information stored in the glyph table. And render the shape of one character to insert the rendered at least one character on the first electronic document.

In this case, according to an embodiment of the present invention, the electronic terminal apparatus 110 for copying and maintaining the shape of characters included in the PDF document may further include a management key generation unit 114. [

The management key generation unit 114 generates a management key for each of the at least one glyph information based on the index key corresponding to each of the at least one glyph information when the extraction of the at least one glyph information is completed, And generates a management key for each of the at least one character based on the index key assigned to each of the at least one character.

In this case, the glyph information storage unit 112 may store the at least one glyph information and the management key for each of the at least one glyph information on the glyph table, and the character inserting unit 113 may store the glyph information The method comprising the steps of rendering the shape of the at least one character with reference to the stored glyph information corresponding to the same management key as the management key for each of the at least one character from the table, Can be inserted.

In addition, according to an embodiment of the present invention, the glyph information extracting unit 111 may include a duplicate checking unit 115 and a duplicate elimination extracting unit 116.

The duplicate checking unit 115 compares the index keys assigned to each of the at least one character with each other to check whether or not two or more characters to which the same index key is assigned among the at least one character are present.

When there are two or more characters to which the same index key is allocated among the at least one character, the duplicate elimination extracting unit 116 extracts duplicate characters from the glyph map by using an index key identical to an index key assigned to each of the at least one character Extracts only one piece of glyph information from the at least one piece of glyph information corresponding to two or more characters to which the same index key is assigned.

In addition, according to an embodiment of the present invention, after the rendered at least one character is inserted on the first electronic document, the glyph information extracting unit 111 extracts the plurality of characters included in the PDF document If at least one other character in the first electronic document is to be copied, an additional copy command to the first electronic document may be applied to extract at least one other character from the glyph map.

At this time, the glyph information storage unit 112 checks whether the same glyph information as the glyph information of the at least one other character is already stored on the glyph table, and determines whether the glyph information of the at least one other glyph And the character insertion unit 113 may further store the at least one other character based on the glyph information of the at least one other character stored in the glyph table, May be rendered to further insert the rendered at least one other character on the first electronic document.

Hereinafter, with reference to FIG. 2 and FIG. 3, the operation of the electronic terminal device 110 for copying and maintaining the shape of characters included in a PDF document according to an exemplary embodiment of the present invention will be described in detail.

FIGS. 2 and 3 are diagrams for explaining an electronic terminal device 110 for copying and maintaining the shape of characters included in a PDF document according to an embodiment of the present invention.

2, a copy instruction to the first electronic document 220 for at least one character indicated by the reference numeral 211 among a plurality of characters included in the PDF document 210 by the user The glyph information extracting unit 111 can extract the glyph information for at least one character 211 from the glyph map included in the PDF document 210. [

Here, the glyph information will be described in detail with reference to an example shown in FIG. 3 as information on a predetermined character shape for rendering and displaying specific characters on the screen.

As shown in Fig. 3, assume that a character "a" is rendered on the screen and displayed. At this time, the glyph information for "a " means coordinate information for points indicated by dots in reference numeral 310. [

That is, in order to render and display "a" on the screen, as shown at 310, there may be a number of points with an outline of the image "a "quot; a "may be displayed.

Here, the glyph information means vector data represented by coordinate values on a two-dimensional plane with respect to a plurality of points having an outline of an image "a" shown at reference numeral 310,

In this way, since the glyph information for the character "a" is composed of the vector data as shown in the reference numeral 320, the electronic terminal device is based on the coordinate values included in the glyph information 320 for the character & So that the character image "a" can be completely rendered and displayed on the screen, as shown at 330. [

As described above, the glyph information 320 for the character "a " indicates that the glyph information 320 for the point indicated by the reference numeral 310 is " Vector data represented by coordinate values.

Here, the glyph map refers to a mapping table storing glyph information indicating the shape of the plurality of characters in order to render and display the plurality of characters on the PDF document 210.

In this regard, in the gripe map, each of the glyph information stored in the glyph map and an index key for indexing the respective glyph information are stored in association with each other, and two or more identical characters exist among the plurality of glyphs In this case, the glyph information and the index key for the two or more identical characters are stored in association with each other on the glyph map.

For example, the PDF document 210 of the embodiment of FIG. 2 may include a glyph map in which information as shown in Table 1 below is stored.

Glyph information for a plurality of characters The glyph information for the character "Choi" Glyph information about the character "near" The glyph information for the character "de" ... Index key Index key 1 Index key 2 Index key 3 ...

Basically, the glyph map stores both the glyph information for the plurality of characters included in the PDF document 210 and the index key corresponding thereto, as shown in Table 1 above. However, in the PDF document 210, Is a duplicate character appearing more than once on the PDF document 210, such as "desktop "," laptop ", etc., for which the glyph information for the "top" The index keys are not stored in the PDF document 210 for the number of times of duplication, but are stored in association with each other.

For each of the plurality of characters included in the PDF document 210, an index key for indexing the glyph information corresponding to each of the plurality of characters in the glyph map is assigned.

For example, with regard to the character "Choi" among the plurality of characters included in the PDF document 210, since the index key corresponding to the glyph information for the character "Choi" Index key 2 "corresponding to the character" near "in Table 1 is" index key 2 " May be assigned.

When a copy instruction to the first electronic document 220 is applied by the user to at least one character 211 indicated by the reference numeral 211 among the plurality of characters included in the PDF document 210 under this situation , The glyph information extraction unit 111 corresponds to an index key identical to an index key assigned to each of at least one character 211 from the glyph map based on the index key assigned to each of the at least one character 211 So that at least one of the stored pieces of glyph information can be extracted.

For example, since the index key assigned to the character "Choi" is "Index key 1 ", the glyph information extraction unit 111 extracts the index key 1 Quot ;, and the index key assigned to the character "near" is "index key 2" for the character "near" The extraction unit 111 can extract the glyph information for the character "near" stored in association with the "index key 2" from the glyph map shown in Table 1 above. In this way, the glyph information extractor 111 can extract the at least one glyph information corresponding to each of the at least one character 211 from the glyph map.

At this time, the redundancy check unit 115 compares the index keys allocated to each of the at least one character 211 with each other to determine whether there is at least one character among the at least one character 211 to which the same index key is allocated And the duplicate elimination extracting unit 116 assigns to each of the at least one letter 211 from the glyph map when there are two or more characters to which the same index key is assigned among the at least one letter 211 When extracting the at least one piece of glyph information stored in association with the same index key as the index key, extracts only one piece of glyph information from the pieces of glyph information corresponding to two or more characters to which the same index key is assigned can do.

In this regard, in the embodiment of FIG. 2, for the character "top" of at least one character 211, characters that are duplicated twice or more on the PDF document 210, such as "desktop & The redundancy check unit 115 can confirm that the index key assigned to the character "top " is duplicated twice or more by the words" desktop & When extracting the at least one piece of glyph information stored corresponding to an index key identical to an index key assigned to each of at least one character 211 from the glyph map, , It is not possible to extract two pieces of the same glyph information by the word "laptop ", but only one piece of glyph information for the character" top "

When the at least one glyph information is extracted from the glyph map, the management key generation unit 114 generates a management key for each of the at least one glyph information based on the index key corresponding to each of the at least one glyph information, And generate a management key for each of at least one character 211 based on the index key assigned to each of the at least one character 211. [

In this regard, the management key generation unit 114 applies an index key corresponding to each of the at least one glyph information to a predetermined key generation function as an input, thereby generating a management key for each of the at least one glyph information can do.

The management key generation unit 114 also applies an index key assigned to each of the at least one character 211 as an input to the selected key generation function to generate a management key for each of the at least one character 211 Lt; / RTI >

For example, the management key generation unit 114 applies "index key 1" as an input to the selected key generation function since the index key corresponding to "index key 1" is associated with the glyph information for the character "best" Management key 1 "can be generated with the management key corresponding to the glyph information for the character" Choi ", and the index key assigned to the character " ) Can generate "management key 1" with a management key corresponding to the character "best" by applying "index key 1"

Thus, the management key corresponding to the glyph information for the character "Choi " and the management key corresponding to the character" Choi " can all be generated using the "management key 1"

When the generation of the management key for each of the at least one glyph information and the management key for each of the at least one character is completed, the glyph information storage unit 112 generates a glyph table for managing glyph information The at least one glyph information and the management key for each of the at least one glyph information may be associated with each other on the glyph table.

For example, when a management key corresponding to the glyph information for the character "Choi" among the at least one glyph information is generated by the "management key 1 ", and a management key corresponding to the glyph information for the character" Key 2 ", and the management key corresponding to the glyph information for the character "de" is generated as "management key 3 ", information may be stored on the glyph table as shown in Table 2 below.

At least one glyph information The glyph information for the character "Choi" Glyph information about the character "near" The glyph information for the character "de" ... Management key Management key 1 Management Key 2 Management Key 3 ...

Then, the character inserting unit 113 refers to the stored glyph information corresponding to the same management key as the management key for each of the at least one character 211 from the glyph table, and displays the shape of the at least one character 211 And then insert at least one rendered character 221 on the first electronic document 220, as shown at 221. [

For example, as a result of generating a management key for each of at least one character 211 based on an index key assigned to each of at least one character 211 by the management key generation unit 114, Management key 3 "is generated for the character" da ", the character inserting section 113 generates the character string" management key 1 " The shape of the character "Choi" is rendered on the first electronic document 220 by referring to the glyph information for the character "Choi" stored in correspondence with the "management key 1" And the shape of the character "near" is rendered on the first electronic document 220 with reference to the glyph information about the character "near" stored corresponding to the "management key 2 "Quot; and " stored "corresponding to" management key 3 " It is possible to render and insert the shape of the character "de" on the first electronic document 220 by referring to the glyph information about the character.

Thus, after at least one rendered character 221 on the first electronic document 220 has been inserted, the at least one other character among the plurality of characters included in the PDF document 210 by the user When an additional copy instruction to the first electronic document 210 is applied, the glyph information extracting unit 111 can extract the glyph information for the at least one other character from the glyph map according to the above-described method of extracting the glyph information .

The glyph information storage unit 112 may further store the glyph information for the at least one other character on the glyph table according to the glyph information storing method described above, It is possible to check first whether or not the same glyph information as the glyph information for the at least one other character is already stored on the glyph table before further storing the glyph information for the character.

If it is determined that the same glyph information as the glyph information for the at least one other character is already stored on the glyph table, the glyph information storage unit 112 stores the overlapped glyph information on the glyph table Since there is no need to store again, only the remaining glyph information other than the overlapping glyph information among the glyph information for the at least one other character can be additionally stored on the glyph table.

Then, the character inserting unit 113 renders the shape of the at least one other character based on the glyph information of the at least one other character stored in the glyph table according to the above-mentioned character inserting method, And may further insert the rendered at least one other character on the electronic document 220.

As a result, the electronic terminal device 110 for copying the shape of the characters included in the PDF document according to the embodiment of the present invention, when a copy command to another electronic document is applied to specific characters included in the PDF document Extracting the glyph information for the specific characters from the glyph map included in the PDF document, storing the glyph information on the predetermined glyph table, and extracting, based on the glyph information for the specific characters stored in the glyph table, The shape of specific characters is rendered and inserted on the other electronic document so that the shape of the specific characters can be copied to another electronic document while maintaining the same shape as that on the PDF document.

FIG. 4 is a flowchart illustrating a method of copying shape preservation for characters included in a PDF document of an electronic terminal device according to an exemplary embodiment of the present invention.

In step S410, when a copy instruction to the first electronic document is applied to at least one character among a plurality of characters included in the PDF document, the glyph map included in the PDF document The glyph information for the at least one character is extracted from the mapping table in which the glyph information indicating the shape of the plurality of characters is stored so as to render and display characters on the PDF document.

In step S420, a glyph table for managing glyph information is generated and the glyph information for the at least one character is stored in the glyph table.

In operation S430, the shape of the at least one character is rendered based on the glyph information of the at least one character stored in the glyph table to insert the rendered at least one character on the first electronic document do.

In this case, according to an embodiment of the present invention, the glyph map stores the respective glyph information stored in the glyph map and index keys for indexing the respective glyph information in association with each other, If there are two or more identical characters in the glyph map, the glyph information and the index key for the two or more identical characters may be stored in the glyph map in association with each other, An index key for indexing the glyph information corresponding to each of the plurality of characters may be allocated.

At this time, in step S410, based on the index key allocated to each of the at least one character, at least one character string corresponding to the index key assigned to each of the at least one character from the glyph map Can be extracted as the glyph information for the at least one character.

At this time, in step S420, the at least one glyph information may be stored in the glyph table. In step S430, based on the at least one glyph information stored in the glyph table, May be rendered to insert the rendered at least one character on the first electronic document.

According to an embodiment of the present invention, a method of copying shape preservation for a character included in a PDF document of the electronic terminal device may include a step of, when extraction of the at least one piece of glyph information is completed, Generating a management key for each of the at least one glyph information based on the index key and generating a management key for each of the at least one character based on the index key assigned to each of the at least one character As shown in FIG.

According to an embodiment of the present invention, the generating of the management key may include inputting an index key corresponding to each of the at least one glyph information as input to a predetermined key generation function, The management key for each of the at least one character can be generated by applying the index key assigned to each of the at least one character to the selected key generation function as an input .

At this time, in step S420, the at least one glyph information and the management key for each of the at least one glyph information may be stored in correspondence with each other on the glyph table. In step S430, Rendering the shape of the at least one character with reference to the stored glyph information corresponding to the same management key as the management key for each character of the first electronic document and then inserting the rendered at least one character on the first electronic document .

Also, according to an embodiment of the present invention, in step S410, index keys allocated to each of the at least one character are compared with each other so that at least one character among the at least one character, Determining whether or not at least one of the at least one of the at least one character and the at least one character has the same index key assigned to the at least one character; And selecting and extracting only one piece of glyph information from the at least one piece of glyph information corresponding to two or more characters to which the same index key is assigned when extracting the corresponding at least one piece of glyph information.
