1 is a diagram illustrating a structure of a document editing apparatus that enables display of a document to which a font configured in an unsupported data format is applied according to an embodiment of the present invention.

Referring to FIG. 1 , a document editing apparatus 110 that enables display of a document to which a font configured in an unsupported data format is applied according to an embodiment of the present invention includes an alternative font table maintaining unit 111, a font It includes a data storage unit 112 , a font identifier verification unit 113 , a stored font verification unit 114 , a replacement font selection unit 115 , and a document reconstruction unit 116 .

The replacement font table maintaining unit 111 includes a font identifier for each of a plurality of different first fonts configured in a first data format and a replacement font (the replacement font) previously designated as being able to replace each of the plurality of first fonts. (The font is a font configured in the second data format) and stores and maintains a table of replacement fonts in which replacement font identifiers for each other are recorded in correspondence with each other.

For example, assuming that the name of the font configured in the first data format starts with 'A' and the name of the font configured in the second data format starts with 'B', the replacement font table contains Table 1 and Information may also be recorded.

Font identifiers for the plurality of first fonts Alternative font identifier for alternate fonts font name font identifier font name font identifier A used gothic A1 B gothic B1 A Shin Myeongjo A2 B Myeong-style B2 A new roll A3 B-rolling body B3 ... ...

The font data storage unit 112 stores a font identifier for each of a plurality of different second fonts configured in the second data format and font data for each of the plurality of second fonts in correspondence with each other.

Here, the font data is data used to apply a font format corresponding to characters included in the document when the document is loaded.

For example, according to the above-described example, information may be stored in the font data storage unit 112 as shown in Table 2 below.

Font names of the plurality of second fonts font identifier font data B gothic B1 font data 1 B Myeong-style B2 font data 2 B roll B4 font data 3 B magnification B5 font data 4 ... ... ...

When a first document is opened through a document writing program capable of loading only font data configured in the second data format, the font identifier check unit 113 reads the document data for the first document and writes it to the first document. A font identifier for a font applied to the included plurality of characters is checked.

Here, a font identifier for a font applied to a plurality of characters included in the first document is inserted in the document data.

When the font identifier for the font applied to the plurality of characters is identified as the first font identifier that is one of the font identifiers for each of the plurality of first fonts, the stored font check unit 114 is configured to replace the font identifier. After checking the first replacement font identifier recorded corresponding to the first font identifier from the font table, it is checked whether a font identifier matching the first replacement font identifier is stored in the font data storage unit 112 .

When it is confirmed that the font identifier matching the first alternative font identifier is stored in the font data storage unit 112 , the replacement font selection unit 115 may store the plurality of the font data stored in the font data storage unit 112 Among the font data for the second fonts, first font data corresponding to the first replacement font identifier is selected as the replacement font data.

The document reconfiguration unit 116 reconstructs the first document by loading the replacement font data from the font data storage unit 112 and applying a font format according to the replacement font data to the plurality of characters, and then reconstructs The first document that has been created is displayed on the screen.

For example, assuming that the font 'A middle-gothic' is applied to the plurality of characters included in the first document, only font data configured in the second data format with a font name starting with 'B' can be loaded. When the first document is opened through an existing document creation program, the font identifier check unit 113 reads document data for the first document and checks the font identifier for the font applied to the plurality of characters. can

At this time, when the font identifier for the font applied to the plurality of characters is identified as 'A1', which is the font identifier for 'A middle-gothic', the stored font check unit 114 is the replacement font as shown in Table 1 above. After checking 'B1', which is the font identifier for 'B Gothic', as the first replacement font identifier recorded in correspondence with 'A1' from the table, 'B1' and 'B1' are stored in the font data storage unit 112 as shown in Table 2 above. You can check whether a matching font identifier is stored.

At this time, when it is confirmed by the stored font checking unit 114 that a font identifier matching 'B1' is stored in the font data storage unit 112 as shown in Table 2, the alternative font selection unit 115 is the Among the font data for the plurality of second fonts stored in the font data storage unit 112 as shown in Table 2, 'font data 1', which is font data corresponding to 'B1', may be selected as the replacement font data.

Then, the document reconstructing unit 116 loads 'font data 1' from the font data storage unit 112 as shown in Table 2, and 'B gothic font' is a font format according to 'font data 1' for the plurality of characters. After reconstructing the first document by applying ', the reconstructed first document may be displayed on the screen.

At this time, according to an embodiment of the present invention, the replacement font selection unit 115 determines that the font identifier matching the first replacement font identifier is not stored in the font data storage unit 112, A configuration for selecting font data may include a similarity database 120 , a Euclidean distance calculating unit 121 , and an alternative font selection processing unit 122 .

In the similarity database 120 , a font identifier for each of a plurality of fonts previously designated as applicable to characters and a characteristic vector designated in advance for each of the plurality of fonts based on a predetermined similarity between each font are stored in correspondence with each other has been

For example, information may be stored in the similarity database 120 as shown in Table 3 below.

Font names of multiple fonts font identifier characteristic vector B gothic B1 [0 1 2 3] B Myeong-style B2 [5 6 7 8] B-rolling body B3 [9 10 11 12] B roll B4 [13 14 15 16] B magnification B5 [15 16 17 18] ... ... ...

In this case, the characteristic vector stored in Table 3 is a vector value arbitrarily determined by a developer, and the developer pre-examines the characteristics of each of the plurality of fonts, and the more similar the fonts among the fonts, the more the Euclidean distance (Euclidean distance). Distance) may be assigned to each font so that the feature vector is calculated to be small. That is, the feature vector may be a measure for distinguishing the similarity between the respective fonts.

When it is determined that the font identifier matching the first replacement font identifier is not stored in the font data storage unit 112 , the Euclidean distance calculating unit 121 refers to the similarity database 120 and refers to the first replacement font identifier. A first feature vector stored in correspondence with . is checked, and a Euclidean distance between the first feature vector and a feature vector corresponding to each of the font identifiers of the plurality of second fonts is calculated.

Here, the Euclidean distance refers to a distance between two vectors and may be calculated according to Equation 1 below.

In Equation 1, D denotes a Euclidean distance, and p _i and q _i denote i-th components included in the two feature vectors. As the Euclidean distance between two feature vectors is small, the two vectors can be regarded as similar vectors, and as the Euclidean distance between two feature vectors increases, the two vectors can be regarded as dissimilar vectors.

The alternative font selection processing unit 122 selects, as a second alternative font identifier, a font identifier corresponding to a feature vector in which the Euclidean distance to the first feature vector is calculated as a minimum among font identifiers for the plurality of second fonts, , selects second font data corresponding to the second replacement font identifier from among the font data for the plurality of second fonts stored in the font data storage unit 112 as the replacement font data.

For example, the font applied to the plurality of characters was identified as 'A3', which is the font identifier for 'A Saegulrim' by the font identifier confirmation unit 113, and Table 1 by the stored font confirmation unit 114 Assume that 'B3' for 'B Gulimche' is identified as the first alternate font identifier recorded in correspondence with 'A3' from the alternative font table as shown in FIG.

At this time, when it is confirmed that 'B3' is not stored in the font data storage unit 112 as shown in Table 2, the Euclidean distance calculating unit 121 refers to the similarity database 120 as shown in Table 3, and ' '[9 10 11 12]', which is a stored first feature vector corresponding to B3', can be checked, and '[9 10 11 12]', which is the first feature vector, and The Euclidean distance between the feature vectors corresponding to each font identifier can be calculated.

The alternative font selection processing unit 122 selects a font identifier corresponding to a feature vector in which the Euclidean distance from the first feature vector '[9 10 11 12]' among the font identifiers for the plurality of second fonts is calculated as a minimum. A second alternative font identifier may be selected.

If the font identifier corresponding to the feature vector in which the Euclidean distance to the first feature vector '[9 10 11 12]' is calculated is selected as 'B5', the alternative font selection processing unit 122 is 'B5' 'Font data 4', which is font data corresponding to , may be selected as the replacement font data.

Then, the document reconstructing unit 116 loads 'font data 4', which is the replacement font data, from the font data storage unit 112 as shown in Table 2, and a font according to 'font data 4' for the plurality of characters. After the first document is reconstructed by applying the form 'B magnification', the reconstructed first document may be displayed on the screen.

At this time, according to an embodiment of the present invention, the document editing apparatus 110 maintains the font width table in a configuration for maintaining the layout of the existing document even when the font format according to the replacement font data is applied to the first document. It may further include a part 117 .

The font width table maintaining unit 117 maintains a font width table in which a font identifier for each of the plurality of first fonts and preset character width information corresponding to each of the plurality of first fonts are recorded in correspondence with each other. Save and keep

Here, the width information for each character means size information on the horizontal axis width of each character when any one of the plurality of first fonts is applied to each of the plurality of characters.

For example, information may be recorded in the font width table as shown in Table 4 below.

Font names of the plurality of first fonts font identifier Width information per character message horizontal axis width A used gothic A1 go 10 thing 8 ... ... A Shin Myeongjo A2 go 9 thing 7 ... ... A new roll A3 go 8 thing 6 ... ... ... ... ... ...

In this case, according to an embodiment of the present invention, the document reconstruction unit 116 may include a width information check unit 118 and a document reconstruction processing unit 119 .

When the first font data is selected as the replacement font data, the width information check unit 118 checks the width information for each first character recorded corresponding to the font according to the first font identifier from the font width table. .

The document reconstruction processing unit 119 loads the replacement font data from the font data storage unit 112 and applies a font format according to the replacement font data to the plurality of characters, but based on the width information for each first character By adjusting the width of each of the plurality of characters, the first document is reconstructed and then the reconstructed first document is displayed on the screen.

For example, the font identifier for the font applied to the plurality of characters by the font identifier check unit 113 is confirmed as 'A1', which is the font identifier for 'A Middle Gothic', and is applied to the plurality of second fonts. Assuming that 'font data 1' corresponding to 'B1' is selected as the replacement font data among the font data for You can check the width information for each first character recorded in correspondence with 'A Middle Gothic'.

Then, the document reconstruction processing unit 119 loads 'font data 1' from the font data storage unit 112 as shown in Table 2, and 'B gothic font', which is a font format according to 'font data 1' for the plurality of characters. ', but by adjusting the width of each of the plurality of characters based on the width information for each first character, the first document can be reconstructed, and the reconstructed first document can be displayed on the screen .

That is, if a character 'A' exists among the plurality of characters, the first document may be reconstructed by adjusting the horizontal axis width of the character 'A' to '10'.

In addition, according to an embodiment of the present invention, the replacement font selection unit 115 includes the operation processing unit 123 , the candidate font identifier selection unit 124 , the candidate font name display unit 125 , and the change font selection unit 126 . may include more.

After the reconstructed first document is displayed on the screen, when a command to change the replacement font for the plurality of characters is received from the user, the calculation processing unit 123 refers to the similarity database 120 to the replacement font data. A second characteristic vector stored corresponding to a font identifier for a font according to the corresponding font is checked, and a Euclidean distance between the second characteristic vector and a characteristic vector corresponding to each of the font identifiers of the plurality of second fonts is calculated.

The candidate font identifier selection unit 124 is configured to select at least one candidate corresponding to at least one feature vector whose Euclidean distance to the second feature vector is calculated within a preset reference distance among font identifiers for the plurality of second fonts. Select the font identifier as the change candidate font identifier.

When the at least one candidate font identifier is selected as the change candidate font identifier, the candidate font name display unit 125 displays information on the font name for each of the at least one candidate font identifier on the screen.

When a selection command for a first candidate font identifier among the at least one candidate font identifier is received from the user, the change font selection unit 126 selects the plurality of second fonts stored in the font data storage unit 112 . 3rd font data corresponding to the first candidate font identifier from among the font data for , is selected as the change font data.

At this time, when the third font data is selected as the changed font data, the document reconstruction unit 116 loads the changed font data from the font data storage unit 112 and stores the changed font data for the plurality of characters. After the first document is reconstructed by applying a font format according to the above, the reconstructed first document may be displayed on the screen.

For example, if it is assumed that the first document is reconstructed by applying 'B gothic font', which is a font format according to 'font data 1', to the plurality of characters as in the previous example, the operation processing unit 123 may perform the reconstructed After the first document is displayed on the screen, when a command to change the replacement font for the plurality of characters is received from the user, the font identifier for 'Gothic B' with reference to the similarity database 120 as shown in Table 3 above '[0 1 2 3]', which is a stored second feature vector corresponding to 'B1', can be checked, and '[0 1 2 3]', which is the second feature vector, and the plurality of second fonts A Euclidean distance between feature vectors corresponding to each of the font identifiers can be calculated.

In addition, the candidate font identifier selection unit 124 is configured to calculate at least a Euclidean distance between the font identifiers for the plurality of second fonts, '[0 1 2 3]', which is the second characteristic vector, within a preset reference distance. At least one candidate font identifier corresponding to one characteristic vector may be selected as the change candidate font identifier.

In this regard, if the at least one candidate font identifier is 'B2' and 'B4', the candidate font name display unit 125 displays 'B Myeongjo font' and 'B Gurum, which are font names for 'B2' and 'B4', respectively. ' can be displayed on the screen.

At this time, as 'B roll' is selected from 'B Myeongjo font' and 'B roll' displayed on the screen from the user, when a selection command for 'B4' among 'B2' and 'B4' is received, change font selection The unit 126 changes the font data 'font data 3' corresponding to 'B4' among the font data for the plurality of second fonts stored in the font data storage unit 112 as shown in Table 2 above. data can be selected.

In this way, when 'font data 3' is selected as the changed font data, the document reconfiguration unit 116 loads 'font data 3' from the font data storage unit 112 as shown in Table 2 above, and adds it to the plurality of characters. After the first document is reconstructed by applying 'B Gurim', which is a font format according to 'font data 3', the reconstructed first document may be displayed on the screen.

In addition, according to an embodiment of the present invention, the replacement font selection unit 115 includes a character region extraction unit 127 , a replacement character generation unit 128 , a matrix generation unit 129 , an operation matrix generation unit 130 , It may further include an alternative character font confirmation unit 131 and a detailed alternative font selection unit 132 .

After the reconstructed first document is displayed on the screen, the text area extraction unit 127 receives a font detailed adjustment command for the first character among the plurality of characters from the user, the text area extracting unit 127 is configured to pre-enclose the first character. By generating a rectangular area of a predetermined size, the rectangular area is extracted as the first character area.

The replacement character generating unit 128 is configured to generate a second font that exists in the first character area based on font data for the remaining fonts except for a font that matches the font applied to the first character among the plurality of second fonts. By changing the font of the first character to a font corresponding to each of the remaining fonts, replacement character areas corresponding to each of the remaining fonts (the size of the replacement character areas are the same as the size of the first character area) ) is created.

The matrix generator 129 divides the first text area and the replacement text area into nxn partial rectangular areas each consisting of n horizontal and n vertical areas, respectively, and then, for each of the nxn partial rectangular areas, When a part of the first character is included in each of the nxn partial rectangular regions, a code of 1 is assigned, and when a part of the first character is not included, a code of 0 is assigned, so that the first character region and an nxn matrix for each of the replacement character regions.

The operation matrix generating unit 130 calculates a Hadamard product of an nxn matrix for each of the replacement character regions with an nxn matrix for the first character region, thereby generating the replacement character regions. Create an nxn operation matrix corresponding to each.

Here, the Hadamard product means an operation of multiplying each component in a matrix or vector of the same size. When there are two matrices '[abc]' and '[xyz]', A matrix can be expressed as '[ax by cz]'.

The replacement character font check unit 131 counts the number of component values of 1 included in the nxn operation matrix corresponding to each of the replacement character areas, and then the component value of 1 among the replacement character areas is maximized. A first replacement character area corresponding to the counted nxn operation matrix is selected, and a font identifier of a first font corresponding to the first replacement character area among the font identifiers of the remaining fonts is checked.

The detailed replacement font selection unit 132 converts fourth font data corresponding to the font identifier for the first font among the font data for the remaining fonts stored in the font data storage unit 112 as detailed replacement font data. choose

At this time, when the fourth font data is selected as the detailed replacement font data, the document reconstruction unit 116 loads the detailed replacement font data from the font data storage unit 112 and provides the detailed replacement font for the first character. After the first document is reconstructed by applying a font format according to data, the reconstructed first document may be displayed on the screen.

For example, if it is assumed that the first document is reconstructed by applying 'B gothic font', which is a font format according to 'font data 1', to the plurality of characters as in the previous example, the character area extraction unit 127 is reconfigured. After the first document is displayed on the screen, when a detailed font adjustment command for a character 'a' among the plurality of characters is received from the user, as shown by a blue line in reference numeral 210 of FIG. Similarly, by creating a rectangular area of a predetermined size surrounding the character 'a', the rectangular area may be extracted as the character area 210 .

The replacement character generating unit 128 is configured to generate a character area ( 210), by changing the font of the character 'A' to a font corresponding to each of the remaining fonts, it is possible to generate replacement character areas corresponding to each of the remaining fonts.

Thereafter, assuming that n is '4', the matrix generating unit 129 generates '4' x '4' of the text area 210 and the replacement text area, each of '4' horizontally and '4' vertically. It can be divided into four partial rectangular regions. In addition, the matrix generating unit 129 may generate a portion of the letter 'A' in each of the '4' x '4' partial rectangular regions for each of the '4' x '4' partial rectangular regions. '4' x '4' for each of the character area 210 and the replacement character areas by assigning a code of 1 if included and assigning a code of 0 if not included in the first character You can create a matrix of

2, after the matrix generator 129 divides the text area 210 into '4' x '4' partial rectangular areas, each of the '4' x '4' partial rectangular areas A figure is shown for explaining a process of generating a matrix 230 of '4' x '4' for the character area 210 by assigning a code of 1 or 0 to .

The matrix generator 129 divides the text area 210 into '4' x '4' partial rectangular areas, as shown by reference numeral 220, and then adds each of the '4' x '4' partial rectangular areas. By assigning a code of 1 if the part of the character called 'A' is included, and assigning a code of 0 if the part of the character called 'A' is not included, as shown in reference numeral 230, the character area 210 A matrix 230 of '4' x '4' may be generated for .

In this way, the matrix generator 129 generates a matrix 230 of '4' x '4' for the character region 210 and then '4' x '4' for each of the replacement character regions. You can create a matrix of

The operation matrix generator 130 calculates a Hadamard product of a matrix of '4' x '4' for each of the replacement character regions and a matrix of '4' x '4' for the character region 210 . By doing so, it is possible to generate an operation matrix of '4' x '4' corresponding to each of the replacement character regions.

In addition, the replacement character font check unit 131 may count the number of component values of 1 included in the operation matrix of '4' x '4' corresponding to each of the replacement character regions.

If, among the replacement character regions, a 'B roll' is applied to the character 'A' as the replacement character region corresponding to the operation matrix of '4' x '4' in which the component value of 1 is maximally counted. When the 'alternative character area 1' is selected, the replacement character font check unit 131 is the font identifier 'B4' for 'B Gulim' corresponding to the 'alternative character area 1' among the font identifiers for the remaining fonts. can be checked.

Then, the detailed alternative font selection unit 132 is added to the font identifier 'B4' for 'B Gurum' among the font data for the remaining fonts stored in the font data storage unit 112 as shown in Table 2 above.
