When a load command for the first electronic document is applied from the user 130 , the identifier check unit 114 checks the identifier of the first font applied to the first electronic document from the document data of the first electronic document do.

Here, the document data of the first electronic document includes information on the identifier of the first font applied to the first electronic document.

When the identifier of the first font is confirmed by the identifier confirmation unit 114 , the font confirmation unit 115 matches the identifier of the first font among the identifiers of the plurality of fonts stored in the data storage unit 111 . Check if the identifier exists.

When it is confirmed by the font checking unit 115 that there is no identifier matching the identifier of the first font among the identifiers of the plurality of fonts, the additional confirmation unit 116 refers to the font table and refers to the plurality of fonts. It is checked whether an identifier matching the identifier of the first font exists among the identifiers of the original fonts.

When the replacement font application unit 117 confirms that the identifier of the first original font exists as an identifier matching the identifier of the first font among the identifiers of the plurality of original fonts by the additional confirmation unit 116, After checking the identifier of the first replacement font corresponding to the first original font by referring to the font table, the first replacement font stored in the data storage unit 111 based on the identifier of the first replacement font Font data for is loaded to apply the first replacement font to each of the first characters included in the first electronic document on the first electronic document.

Hereinafter, the operations of the font confirmation unit 115 , the additional confirmation unit 116 , and the replacement font application unit 117 will be described in detail, for example.

First, it is assumed that a load command for the first electronic document is applied from the user 130 , and by the identifier verification unit 114 , the first electronic document applied to the first electronic document is obtained from the document data of the first electronic document. Assume that the identifier of the font is identified as 'B3'.

In this case, the font check unit 115 may check whether an identifier matching 'B3' exists among the identifiers of the plurality of fonts stored in the data storage unit 111 .

In relation to this, since identifiers of each of a plurality of predefined fonts are stored in the data storage unit 111 as shown in Table 1, such as 'A1, A2, A3, A4, A5', the font check unit 115 may store the data It can be confirmed that there is no identifier matching 'B3' among the identifiers of the plurality of fonts stored in the storage unit 111 .

In this way, when it is confirmed by the font confirmation unit 115 that there is no identifier matching 'B3' among the identifiers of the plurality of fonts, the additional confirmation unit 116 refers to the font table and refers to the plurality of originals. It can be checked whether an identifier matching 'B3' exists among the identifiers of the fonts.

In relation to this, in the font table as shown in Table 2, the identifier of each of the plurality of original fonts is recorded as 'B1, B2, B3, B4, B5', and among the plurality of original fonts, 'B3' is Since it is recorded as the identifier of 'original font 3', the additional check unit 116 may confirm the identifier of 'original font 3' as an identifier that matches 'B3' among the identifiers of the plurality of original fonts.

Then, the replacement font application unit 117 refers to the font table, checks the identifier of the first replacement font corresponding to 'original font 3', and based on the identifier of the first replacement font, the data storage unit ( 111) to load the font data for the first replacement font stored in 111) to apply the first replacement font to each of the first characters included in the first electronic document on the first electronic document can

In relation to this, in the font table as shown in Table 2, it is recorded that the first replacement font corresponding to 'original font 3' is 'Font 3' and the identifier of 'Font 3' is 'A3', so the replacement font is applied The unit 117 may identify 'A3' as the identifier of the first replacement font corresponding to 'original font 3'.

At this time, since the font data for 'font 3' stored in the data storage unit 111 as shown in Table 1 is 'font data 3', the replacement font application unit 117 stores data based on 'A3'. By loading 'font data 3' from the unit 111, 'font 3' may be applied to each of the first characters on the first electronic document.

In this way, when the first replacement font is applied to each of the first characters by the replacement font application unit 117, the layout adjustment unit 118 refers to the glyph table and the kerning table, and applies the first original font to the font. Based on the corresponding glyph width information and the kerning information corresponding to the first original font, the glyph width of each of the first characters and the character spacing between the first characters are adjusted in the first electronic document.

At this time, according to an embodiment of the present invention, the layout adjusting unit 118 is a specific configuration for adjusting the glyph width of each of the first characters and the character spacing between the first characters, and the size checking unit 119 . , a grip adjustment unit 120 and an interval adjustment unit 121 may be included.

First, when the first replacement font is applied to each of the first characters on the first electronic document, the size check unit 119 checks the font size of each of the first characters.

The glyph adjusting unit 120 checks the reference glyph width value corresponding to each of the first characters among the reference glyph width values for the plurality of characters corresponding to the first original font recorded in the glyph table, and then Based on a reference glyph width value corresponding to each of the first characters and a font size of each of the first characters, the glyph width of each of the first characters is adjusted in the first electronic document.

At this time, according to an embodiment of the present invention, the glyph adjustment unit 120 may adjust the glyph width of each of the first characters on the first electronic document to a width adjustment value calculated according to Equation 1 below. there is.

는 상기 제1 문자들 중 i번째 문자에 대한 너비 조정 값으로,

는 상기 i번째 문자에 대응되는 기준 글립 너비 값을 의미하고,

는 상기 i번째 문자의 폰트 크기를 의미하며, T는 상기 기준 폰트 크기를 의미한다.here,

is a width adjustment value for the i-th character among the first characters,

is a reference glyph width value corresponding to the i-th character,

denotes the font size of the i-th character, and T denotes the reference font size.

In this way, when the glyph width of each of the first characters is adjusted on the first electronic document by the glyph adjusting unit 120 , the spacing adjusting unit 121 divides the first characters into two consecutive characters. Check the first character pairs to be used, and check the reference kerning value corresponding to each of the first character pairs among the reference kerning values for the plurality of character pairs corresponding to the first original font recorded in the kerning table do.

Then, the spacing adjusting unit 121 based on the reference kerning value corresponding to each of the first character pairs and the font size of the character positioned at the front of the two characters constituting each of the first character pairs, In the first electronic document, a character spacing between two characters constituting each of the first character pairs is adjusted.

At this time, according to an embodiment of the present invention, the spacing adjusting unit 121 on the first electronic document, the character spacing between the two characters constituting each of the first character pairs, in Equation 2 below It can be adjusted with the kerning adjustment value calculated accordingly.

는 상기 제1 문자쌍들 중 j번째 문자쌍에 대한 커닝 조정 값으로,

는 상기 j번째 문자쌍에 대응되는 커닝 값을 의미하고,

는 상기 j번째 문자쌍을 구성하는 두 개의 문자들 중 전단에 위치하는 문자의 폰트 크기를 의미하며, T는 상기 기준 폰트 크기를 의미한다.here,

is a kerning adjustment value for the j-th character pair among the first character pairs,

means a kerning value corresponding to the j-th character pair,

denotes the font size of a character located at the front end of the two characters constituting the j-th character pair, and T denotes the reference font size.

Hereinafter, the operations of the glyph adjusting unit 120 and the spacing adjusting unit 121 will be described in detail, for example.

First, as in the above example, the reference font size is '10(pt)', the first original font is called 'original font 3', and the first characters included in the first electronic document are ' Let's assume it's an autumn sky. In addition, it is said that 'Font 3' is applied to each of 'Autumn Sky' by the replacement font application unit 117, and the font size of each 'Autumn Sky' is set to '12 (pt) 11 ( Assume that it is confirmed as pt) 10(pt) 10(pt)'.

At this time, the glyph adjustment unit 120 may check the reference glyph width value corresponding to each of 'Autumn Sky' among the reference glyph width values for a plurality of characters corresponding to 'original font 3' recorded in the glyph table. .

In relation to this, in the glyph table as shown in Table 3 above, it is recorded that the reference glyph width value corresponding to 'a' among the reference glyph width values for a plurality of characters corresponding to 'original font 3' is '4 (mm)' Therefore, the glyph adjustment unit 120 may check the reference glyph width value corresponding to 'a', such as '4 (mm)'.

In addition, since the font size of 'a' checked by the size check unit 119 is '12(pt)', the glyph adjustment unit 120 adjusts the width adjustment value for 'a' according to Equation 1 above. After calculating as 4.8 (mm)', in the first electronic document, the glyph width of 'a' may be adjusted to '4.8 (mm)'.

In this way, the glyph adjustment unit 120 may adjust the glyph width of each 'autumn sky' on the first electronic document to the width adjustment value calculated according to Equation 1 above.

In this way, when the glyph width of each 'Autumn Sky' is adjusted by the glyph adjusting unit 120, the spacing adjusting unit 121 converts the first character pairs divided into two consecutive characters from 'Autumn Sky' to 'Autumn, Eulha' , sky'.

Then, the interval adjusting unit 121 selects a reference kerning value corresponding to each of 'Autumn, Eulha, and Sky' among the reference kerning values for a plurality of character pairs corresponding to the first original font recorded in the kerning table. can be checked

At this time, it is confirmed that the reference kerning value for 'autumn' among the reference kerning values for a plurality of character pairs corresponding to 'original font 3' recorded in the kerning table as shown in Table 4 is '0.5 (mm)' In the case of 'A', the font size of 'A' was confirmed to be '12 (pt)' by the size check unit 119, so the spacing adjusting unit 120 adjusts the kerning for 'Autumn' according to Equation 2 above. After the value is calculated as '0.6 (mm)', the character spacing between 'A' and 'B' constituting 'Autumn' on the first electronic document may be adjusted to '0.6 (mm)'.

In this way, the spacing adjusting unit 121 adjusts the character spacing between 'A' and 'B', the character spacing between 'B' and 'Ha', and the character spacing between 'Ha' and 'Neul', respectively, in the above equations. It can be adjusted with the kerning adjustment value calculated according to 2.

According to an embodiment of the present invention, the electronic terminal device 110 may further include a font changing unit 122 , a glyph readjusting unit 123 , and an interval readjusting unit 124 .

First, the font changing unit 122 applies the first replacement font to each of the first characters on the first electronic document, and a character between the glyph width of each of the first characters and the first characters After the interval is adjusted, when a font change command instructing to change the font of the first characters to a second font that is one of the plurality of fonts is applied from the user 130, it is stored in the data storage unit 111 The font data for the second font is loaded and the second font is applied to each of the first characters.

When the second font is applied to each of the first characters by the font changing unit 122 , the glyph readjustment unit 123 calculates the glyph width of each of the first characters in the first electronic document, the math Adjust again with the width adjustment value calculated according to Equation 1.

When the glyph width of each of the first characters is adjusted again, the spacing adjusting unit 124 adjusts the spacing between the two characters constituting each of the first character pairs on the first electronic document, the equation Adjust again with the kerning adjustment value calculated according to 2.

Hereinafter, the operations of the font change unit 122 , the glyph readjustment unit 123 , and the interval readjustment unit 124 will be described in detail, for example.

First, as in the above example, the first characters are called 'Autumn Sky', and 'Font 3' is applied to each of the first characters on the first electronic document by the replacement font application unit 117, After the character spacing between each glyph width of 'Autumn Sky' and 'Autumn Sky' is adjusted by the layout adjustment unit 118, the user 130 sets the font of 'Autumn Sky' to one of the plurality of fonts ' Assume that a font change command instructing to change to font 1' is applied.

In this case, the font change unit 122 may load the font data for 'Font 1' stored in the data storage unit 111 and apply 'Font 1' to each of 'Autumn Sky'.

In relation to this, since the font data for 'font 1' stored in the data storage unit 111 as shown in Table 1 is 'font data 1', the font change unit 122 loads 'font data 1' to ' For each of the 'Autumn Sky', 'Font 1' can be applied.

In this way, when 'Font 1' is applied to each of 'Autumn Sky' by the font changing unit 122, the glyph readjustment unit 123 sets the glyph width of each of the first characters on the first electronic document, the The width adjustment value calculated according to Equation 1 may be adjusted again.

In relation to this, according to the above-described example, since the width adjustment value for 'a' calculated according to Equation 1 is '4.8 (mm)', the glyph readjustment unit 123 in the first electronic document, You can adjust the glyph width of ' to '4.8 (mm)' again.

In this way, the glyph readjuster may re-adjust the glyph width of each 'autumn sky' to the width adjustment value calculated according to Equation 1 above.

In this way, when the glyph width of each 'Autumn Sky' is adjusted again, the spacing adjustment unit 124 adjusts the spacing between the two characters constituting each of 'Autumn, Eulha, Sky' on the first electronic document, The kerning adjustment value calculated according to Equation 2 may be adjusted again.

In relation to this, according to the above-described example, since the kerning adjustment value for 'autumn' calculated according to Equation 2 is '0.6 (mm)', the interval readjusting unit 124 is between 'A' and 'B'. You can adjust the character spacing back to '0.6(mm)'.

In this way, the spacing adjustment unit 124 calculates the character spacing between 'A' and 'B', the character spacing between 'B' and 'Ha', and the character spacing between 'Ha' and 'Neul', respectively. It can be adjusted again with the kerning adjustment value calculated according to Equation 2.

That is, when a load command for an electronic document to which a font not supported is applied from the user 130 is applied, the electronic terminal device 110 determines that each of the characters included in the electronic document corresponds to the original font. After applying the preset replacement font, the layout of each of the characters may be adjusted to match the layout of the original font based on the glyph width information and the kerning information corresponding to the original font. In addition, after the replacement font is applied to the characters and the layout of each of the characters is adjusted, the electronic terminal device 110 changes the font applied to the characters from the user 130 to the second font. When a font change command is applied to do this, after changing the font of the characters to the second font, the layout of each of the characters may be adjusted again.

On the other hand, since there is a limit in pre-specifying an alternative font corresponding to each original font for a myriad of original fonts, in some cases, the electronic terminal device 110 and the user 130 provide the replacement font in advance. A load command for an electronic document to which an unspecified original font is applied may also be applied.

Therefore, according to an embodiment of the present invention, when the load command for the electronic document to which the original font to which the replacement font is not previously specified is applied, the replacement font application unit 117 receives from the user 130, As a configuration for applying a preset basic font to characters included in the electronic document, the basic font application unit 125 may be included.

In relation to this, when it is confirmed that an identifier identical to the identifier of the first font does not exist among the identifiers of the plurality of original fonts recorded in the font table, the basic font application unit 125 is configured to perform the data storage unit 111 ) to load font data for a preset default font from ) and apply the default font to each of the first characters on the first electronic document.

Here, the basic font is a font included in the plurality of fonts.

For example, it is assumed that the identifier of the first font applied to the first electronic document is identified as 'C1' from the document data of the first electronic document by the identifier confirmation unit 114 .

At this time, since the identifiers of the plurality of fonts are stored in the data storage unit 111 as shown in Table 1, such as 'A1, A2, A3, A4' and 'A5', the font check unit 115 is the plurality of fonts. It can be confirmed that there is no identifier matching 'C1' among their identifiers. In addition, in the font table as shown in Table 2, since identifiers of the plurality of original fonts are recorded as 'B1, B2, B3, B4', the additional check unit 116 determines ' among the identifiers of the plurality of original fonts'. It can be confirmed that the identifier matching C1' does not exist.

At this time, if the preset basic font is called 'Font 2', the basic font application unit 125 loads the font data for 'Font 2' from the data storage unit 111 and displays the first font on the first electronic document. 1 For each of the characters, 'Font 2' may be applied.

In relation to this, since the font data for 'font 2' stored in the data storage unit 111 as shown in Table 1 is 'font data 2', the basic font application unit 125 receives 'from the data storage unit 111'. Font data 2' may be loaded and 'font 2' may be applied to each of the first characters on the first electronic document.
