Abstract

PURPOSE:To easily change the form of a character without preparing the character datum of the character-form by making the character into graphics and changing the form. CONSTITUTION:Passing points 102 are plurally included in a prototype character 101, the outline of the character can be formed by connecting between the passing points 102 by a straight line. The form of the character can be changed by changing an interpolation system between the passing points 102. A form changing character 103 is the character in which the interval between the passing points 102 is interpolated by Bezier curve. Besides, various forms of the character can be generated by optionally selecting the interpolation system of a three-dimensional curve, etc. And all the passing points are not interpolated by the curve of the same system, and the interpolation system can be changed according to the passing point. A passing point moving character 105 is made by moving the one part of the passing point of the form changing character 103 and thickening the part of the character. Thus, the form of the character can be changed by moving the passing point one by one.

Regarding.

[Prior Art] Generally, in a document creation device, character data such as vector font data is stored in correspondence with a character code.

When changing the size of such a character, the vector font data corresponding to the character code of the character to be changed is used to calculate enlargement/reduction and display.

Also, if you want to change the font of such characters.

The character to be changed is displayed in a dot pattern and then changed, and the vector font data is stored in association with the character code as a new character.

On the other hand, in a single document creation device, geometric figures can be manually created as graphic data, and the manually generated graphic data can be edited.

[Problems to be Solved by the Invention] In the above conventional technology, the shape of a character can only be changed by enlarging/reducing it, so in order to change one font, it is necessary to store it as a separate character, which increases the amount of data. The problem was that there were too many.

An object of the present invention is to make it possible to easily change the font of a character without preparing character data for the font by converting one character into a graphic and changing the shape.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an information processing system including an input device, a display device, a storage device, and a central processing unit. a first conversion means for converting an input character into character data such as vector font data corresponding to the character code of the character; and a data format in which the character data converted by the first conversion means can be treated as a graphic. (hereinafter referred to as graphical character data); and a changing means for changing the shape of the graphical character data converted by the second converting means.

Furthermore, it is preferable to provide a third means for converting the graphic character data converted by the second converting means into a character code.

Further, the third converting means can convert the graphic character data to the original character code by deleting other than the character code.

[Example" Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 6 is a block diagram showing the hardware configuration of a wort processor to which an embodiment of the present invention is applied.

In FIG. 6, 601 is an input device such as a keyboard for inputting characters, etc., 602 is a storage device for storing programs and various data, 603 is a display device such as a CRT display for displaying characters, etc., and 604 is a storage device 603. It is a control device that executes stored programs.

The control device 604 includes a character input section 605 and a character development section 60.
6, a character display section 607, a target designation section 608, and a character editing section 609.

When the character input unit 605 controls the input unit N601 and receives the input of one character, the character input unit 605 stores it in the storage device 603 as a character code.

The character development unit 606 searches the vector font data stored in the storage device 603, calls the vector font data corresponding to the character coat, and converts it to the data format of graphic character data, which will be described later.

Graphically convert characters into graphical character data.

The character display unit 609 displays graphical characters on the display device 603.
to be displayed.

When a part of the characters displayed on the display device b03 is specified by the input device 601, the target specifying unit 607
From among the graphic character data stored in step 3, graphic character data corresponding to the specified character is obtained.

The character editing unit 608 edits the graphic character data obtained by the target specifying unit 607 to change the font.

FIG. 5 is a diagram showing the data structure of graphic character data.

In this embodiment, the font of the characters is changed by treating and editing the characters as figures.

Graphicalization of characters can be realized by converting vector font data previously stored in the storage device 602 into data in the data format shown in FIG.

Therefore, the character expansion unit 606 compiles the vector phono 1-theme stored in the storage device 603 for the character whose font is to be changed, calls the vector font data corresponding to the character code of the character, and Convert to graphic character data according to the data format of graphic character data.

Note that in this embodiment, the font of each character in such a character string is changed at once, considering that the characters whose font is to be changed are often relatively short character strings such as headings and titles. In order to make it possible, data related to one character string is managed as graphic character data,
Each character may be managed as graphic character data.

As shown in FIG. 5, the graphic character data consists of a character string management section 501 and a character data section 502.

The character string management section 501 includes the number of characters 41150.3, 3D information @ 504 that stores the 3D method, a projection plane coordinate field 505, and a vanishing point coordinate field 506.

These fields are used when converting character strings into three-dimensional characters.

The character data section 502 contains data regarding each character constituting the character string, and includes an interpolation method type column 507 that stores the interpolation method.
, a corner modification information field 508, a character code field 509, and a component management information field 510 consisting of a component (outline) number field 510.
5 and a component coordinate column 516 that stores the number and coordinates of passing points of each component.

The interpolation method type column 507 is used when passing points are interpolated with a curved line, and the corner modification information column 508 is used when modifying the corner of one character.

Further, by leaving the character code column 509 and deleting data in other columns, it is possible to easily return to character data in code format.

Next, a method of changing the font of graphical characters in this embodiment will be explained with reference to FIGS. 1 to 4.

FIG. 1 shows an example of changing the C'-f-salary by interpolating passing points with a curve.

In FIG. 1, the original character lot is the character development part 606
It is a character made into a figure.

The original character 101 includes a plurality of passing points 102, and by connecting the passing points 1.02 with a straight line,
It is possible to form the outline of characters.

By changing the interpolation method between passing points 102, the font of the characters can be changed.

The font-changed character 103 is a character obtained by interpolating between the passing points 102 using a Bezier curve. In addition, by freely selecting an interpolation method such as a cubic curve, it is possible to create characters in various fonts. Furthermore, instead of interpolating all passing points using the same curve, it is also possible to change the interpolation method by using one passing point.

The passing point moving character 105 is obtained by moving a part of the passing point of the font change character 103 and making a part of the character thicker.

By moving the passing points one by one in this way, the font can be changed.

The additional passing points 107 are obtained by adding additional passing points 106 between the passing points of the font change character 103 and interpolating them using the same curve as the other parts. In this way, by adding passing points, the font of input characters can be changed.

FIG. 2 shows an example of changing the font by modifying the corners of characters.

By displaying the corner portions as circular arcs like the arc-modified character 201, a Gothic character can be changed to a round Gothic character. This is for all passing points of one character,
Two line segments 203 and 204 connected to the modified passing point 202
This can be achieved by finding a circular arc 205 that is tangent to , and connecting line segments 203 and 204 using this circular arc 205.

Furthermore, like the corner chamfered modification character 206, the font can be changed by cutting the corner chamfer length 207 from two line segments connected to a passing point and connecting the end points of each line segment with another straight line.

FIGS. 3 and 4 show an example of converting graphic characters into three-dimensional characters and changing the font.

In FIG. 3, a circumscribed rectangle of an original character 301 is found, and a projection plane 302 is determined by moving this rectangle. next,
A depth figure 305 whose vertices are two adjacent points 303 and 304 among the passing points and their projected passing points 305 and 306 is displayed. At this time, the display order of the number J) colophon figures 305 is to display them in order from those closest to the original characters 301.

In the example shown in FIG. 3, the projection plane 304 is located at the lower right of the original character 301, so the figure on the left side is displayed first. Regarding the top and bottom, the top shape is displayed first.

Finally, the original figure 301 is displayed and three-dimensional characters 308 are created.

In FIG. 4, first, a vanishing point 401 is determined, and a grid is created by connecting the vanishing point 401 and each passing point with straight lines. Next, the circumscribed rectangle of the original character 403 is adjusted to the grid, and the rectangle is reduced while maintaining the similarity, and the projection plane 403 is
Determine and display. After that, as in the case of Figure 3,
A depth figure 405 whose vertices are two adjacent passing points 404 and 405 and their projected passing points 406 and 407 is displayed. At this time, the drawing order of the depth figures 505 is determined in descending order of the distance to the vanishing point 401. Finally, the original characters 403 are displayed and three-dimensional characters 409 are created.

In this embodiment, several methods of changing the font as described above are prepared, and the user specifies the character or character string for which the font is to be changed, and selects a changing method from one of the several provided changing methods. You can choose from among them.

Next, user operations will be explained using FIGS. 7 and 8.

First, an example of operation in which the font is changed by interpolating the passing points of one character will be described.

As shown in FIG. 7(a), the user can
Move the upper cursor 702 to the range start point 801, which is the first character of the change range, and the range end point 802, which is the last character.
Specify the character string whose font you want to change by specifying the two locations.

In response to this, a method selection window 803 for selecting an interpolation method is displayed as shown in FIG. 7(b). When the user moves the cursor 702 to select an arbitrary interpolation method and presses the execution key, the font of the specified character string will be changed according to the selected interpolation method.

In this case, the processing in this embodiment is such that when the target specifying unit 607 in FIG. 6 receives a character string specified by the user, it obtains graphic character data corresponding to this, and the character editing unit in FIG. When 60g receives the interpolation method selected by the user, it searches the calculation method column 901 of the interpolation calculation table shown in FIG. The purpose is to calculate an interpolation curve and change the shape of the corresponding string.

The above is an example of changing the font of a character string that has already been input, but it may also be possible to first select a method and then interpolate the input string using the selected method. .

Next, an example of operation when moving one passing point will be explained.

As shown in FIG. 8(a), the user first moves the cursor 702 on the display screen 701 to a passing point of the character to be transformed, and performs a target designation operation. At this time, the designated passing point is displayed as a target so that it can be distinguished from other passing points.

Next, as shown in FIG. 8(b), when the cursor 702 is moved, the passing point of the character moves in accordance with the cursor 702. At this time, text based on the moved point is temporarily displayed so that the user can confirm it. When the passing point has been moved to the position desired by the user, press the execution key. This allows the shape of one character to be changed by moving the passing point of one character.

In addition to this, when establishing a new passing point, similarly,
All you have to do is specify the position where the passing point is to be inserted, and then specify the position of the new passing point using the cursor 702.

As explained above, in this embodiment, one character is managed as a graphic, and the font is changed by editing this.

Therefore, it is only necessary to store the character data converted into one graphic and the method of changing the font when editing, and there is no need to store character data for each font.

In addition, it is easy to convert graphical character data back to normal coat format character data, so even if you cannot change the font to the desired font, you can easily restore it to its original state.

[Effects of the Invention] As explained above, according to the present invention, the font is changed by treating characters as figures.

This has the effect that there is no need to prepare character data for many fonts.
