DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external character font generating apparatus for generating external characters.

[0002]

2. Description of the Related Art Conventionally, a word processor is provided with a vector font output device for displaying, printing and outputting document data with high quality. In this vector font output device, for example, font data in which the outline part of a character is represented by a coordinate sequence or a function sequence is stored in a font memory in a one-to-one correspondence with each character. Unregistered characters are registered as external characters. In this case, a dot font arbitrarily created by the user is printed as it is, or a vector font is automatically generated from this dot font and printed.

[0003]

However, when a dot font created by a user is printed as it is, only external characters are messy and uncomfortable, and even when a vector font is automatically generated, the overall balance is lost. However, only the external characters emerge because they are not generated in the intended form. Therefore, it is conceivable to directly create an external character as a vector font. However, it is difficult to create the external character, and the amount of data is increased. An object of the present invention is to make it possible to create an external character font from existing font data.

[0004]

According to the present invention, there is provided character font storage means for storing a plurality of character fonts obtained by combining a plurality of vector parts which are constituent elements of a character;
Display means for displaying a desired character font among a plurality of character fonts stored in the character font storage means;
A vector part designating means for designating a plurality of vector parts to be grouped among the plurality of vector parts of the character font displayed by the display means, and a plurality of vector parts designated by the vector part designating means. Grouping means for grouping, changing means for appropriately changing the arrangement position and size of each vector part grouped by this grouping means, group parts for which the arrangement position and size are appropriately changed by this changing means, and others. And an external character font creating means for creating an external character font having a desired shape by combining the vector parts described above.

DESCRIPTION OF THE FUNCTIONAL BLOCK DIAGRAM (FIG. 1) Font data storage means 1 stores font data for each character component. For example, the font data (for example, a vector font) is stored corresponding to a line, a point, a radical, or the like of one stroke constituting a character. The designation means 2 is an external input device for designating font data stored in the font data storage means 1. The external character creating means 3 creates an external character font by combining the font data specified by the specifying means 2 according to the character shape.

[0006]

An embodiment will be described below with reference to FIGS. First, an outline of a data structure of a character font or the like will be described. FIG. 2 shows a state in which a character font "complete" is constructed by assembling various parts in which character components are made into parts, and this character font is roughly divided into higher-order parts constituting a radical. It is possible to combine "U-kan" and other characters of the "original" character as parts. Upper parts and character fonts consist of a combination of multiple base parts, etc., according to character shapes.Base parts represent character components such as a single line or point, and are basic parts that cannot be further disassembled. , Itself constitutes one outline font, but the “crown” (upper part) is composed of four base parts, and the character font “gen” is also composed of a plurality of base parts.

FIG. 3 is a diagram for explaining the data structure of a part. The base part is composed of skeleton data, flesh data, end shape data, and the like. The skeleton data represents a line segment passing through the center of the character component. In the present embodiment, the type of the skeleton data is (1), and the skeleton is represented by a straight line.
(2) A skeleton represented by a Bezier curve.
(3) Some skeletons are represented by a part of an ellipse. Note that there is a small circle such as a symbol without a skeleton, and this is also treated as a part of the skeleton data. The flesh data indicates the distance from the skeleton as a second-order polynomial (Ax ² + Bx +
The outline data is created by sequentially calculating the thickness from the skeleton based on the skeleton data and the thickness data based on the quadratic polynomial. The shape data at both ends is used to define the line end shape such as the scale of the brush, the end of the circle, etc. Simply by specifying the line end shape, the specified type of line end part is automatically generated, and The size of the line end component is automatically controlled according to the thickness of the line to which the line end component is connected.

The data structure of the character font is composed of the part number (or other character recognition number) of the upper part or the base part, the arrangement position, the enlargement ratio, etc. For example, as shown in FIG. It can be configured by reading three times with changing the length and arrangement position of the skeleton. The data structure of the upper part also includes a part number, an arrangement position, an enlargement ratio, and the like, like the data structure of the character font.

FIG. 4 shows the skeleton of the base part 1/2 times as wide,
It is transformed to 1.4 times in height, and such magnification is defined in the character font and upper part, but in this case, the thickness and both ends shape of the base part do not change, Only the shape changes. FIG.
Is obtained by applying the same magnification as that of FIG. 4 to “oblique payment”. In the case of such an oblique line, it is only necessary to multiply the vertical and horizontal directions of the skeleton. In this case, since the thickness is always defined as a distance in a direction perpendicular to the skeleton, an oblique line as if rotated in a pseudo manner is obtained.

FIG. 6 is a block diagram showing the configuration of the external character font creating device. The main processing control unit 11 controls the overall operation of the external character font creation device according to various programs. For the character code input from the key input device 12, refer to the font definition storage unit 13 or the user font definition storage unit 14. To retrieve the corresponding character, sequentially extract the base parts constituting the character from the base part library 15, change the skeleton data by multiplying the skeleton, and refer to the flesh data and the like. An operation of generating outline data and developing the outline data in the display memory 16 is performed for each base part. Note that the contour data filling process is performed after the contour data is generated. The dot pattern data in the display memory 16 generated in this manner is displayed and output from the CRT display device 17.

The font definition storage unit 13 stores font data corresponding to all characters that can be output, and defines combinations of base parts constituting the characters. For example, the radical of the word "word" consists of six horizontal lines and two vertical lines, where each horizontal line is arranged and how long, and each vertical line is where and how long. Is defined for each line segment. The font definition storage unit 13 is constituted by a ROM (Read Only Memory), and the contents are fixedly stored by the manufacturer.

The user font definition storage unit 14 stores font data having the same data structure as the font definition storage unit 13, and defines an external character font arbitrarily registered by the user. The user font definition storage unit 14 is constituted by a RAM (random access memory).
The external character font desired by the user is written in the user font definition storage unit 14.

The base parts library 15 stores base parts capable of forming various characters. The base parts library 15 is formed of a RAM, the contents of which are fixedly stored by the manufacturer. It is.

The group buffer 18 stores the external character font 1
When defining on a screen, a set of base parts (for example, radicals) is defined as a group in the middle of the definition, and a set of base parts is temporarily stored until the group is arranged. .

FIG. 7 shows a data structure table stored in the base part library 15. here,
The base part is the smallest character component that cannot be further disassembled, and some have two or more skeletons in addition to one skeleton. For this reason, the data structure table has N blocks (N = 1, 2,...) Corresponding to the number of skeletons. Each block data has a different data amount depending on the shape of the skeleton. That is, when the skeleton is a straight line, the data amount is from the first variable to the tenth variable, when the Bezier curve is, the data amount is from the first variable to the fourteenth variable, and when the skeleton is part of an ellipse, the first variable is the first variable. To the twelfth variable, and in the case of a small circle, the data amounts to the first to fourth variables. The first variable (8 bits) defines the shape (kind) of the skeleton by its lower two bits. When the value is "00", it is a straight line, when it is "01", it is a Bezier curve, and when it is "10", it is a part of an ellipse , "11" indicates a small circle. In the first variable, the other bits, that is, the upper 6 bits define the shape of the line end. Of these 6 bits, the upper 3 bits indicate the shape of the start end, and the other 3 bits indicate the shape of the end end. The line shape of the first variable “000” is a straight line cut,
“001” indicates a semicircle cut,..., “111” indicates every other brush at the end of the vertical line. Thus, eight types of line end shapes are prepared in advance.

The second to fourth variables indicate flesh data indicating the thickness when the skeleton shape is a part of a straight line, a Bezier curve, or an ellipse, and indicate the size when the skeleton shape is a small circle. When the skeleton is a straight line, the fifth to eighth variables indicate the position coordinates of the start point and end point of the line segment in the skeleton data. When the skeleton is a Bezier curve, the fifth to twelfth variables are skeleton data and indicate the position coordinates of the start point, first control point, second control point, and end point of the line segment. When the skeleton is part of an ellipse, the fifth to tenth variables
The variables indicate the center coordinates, radius, start angle, and end angle of the ellipse. The ninth and tenth variables when the skeleton is a straight line, the thirteenth and fourteenth variables when a Bezier curve is used, and the eleventh and twelfth variables when part of an ellipse is a straight line cut at the start point. The correction value indicates the straight-line cut correction value at the end point, and the correction value (+
31 to -32) are defined. This correction value indicates how much the cut surface is inclined when the line end is cut by a straight line, and a line end component is added along the cut surface. On the other hand, the upper 2 bits are control data for font change,
This control data is used when changing the Mincho style to the Gothic style.

Next, the operation of this embodiment will be described. FIG. 8 shows a display screen when defining an external character font, and is a screen of a process of referring to a character "word" defined in the font definition storage unit 13 and picking up parts necessary for creating an external character. In this case, in this embodiment, since each stroke is composed of independent base parts, the necessary base parts are sequentially designated for each stroke. Now, when the cursor (arrow in the figure) is set at the base part required for external character registration and the base part is specified for each stroke, the specified base part has the position and magnification in the word "word". The data is copied to the group buffer 18 as it is. Here, when all the base parts constituting the radical "Ninben" of the "word" are sequentially designated, the "Gonben" is copied into the group buffer 18 as one group. At this time, if a reference position is provided in the group buffer 18, the entire group can be handled as one part. As a result, the position can be moved in units of groups and the line thickness can be reduced by specifying the magnification. Enlargement / reduction is possible without changing, and another character can be used as a base without breaking the entire balance.

FIG. 9 shows the character components extracted from the left side of the word "word" as described above, that is, the parts extracted from the right side of the part having the radical "Ninben" as a group and the other characters "total". An example is shown in which an external character is created by combining the components, that is, all the character components other than the radical "Itohen" on the left (parts in black in the figure) as a group. In this case, since two group parts are formed in the group buffer 18, a temporary part number is added to each of them, and these are called to create an external character on the display screen in a form to specify a position and a magnification. When the display screen is checked and a desired external character is created by designating the position and the magnification, the key input device 12 gives a transfer instruction to transfer the character to the user font definition storage unit 14. The unit 11 stores the external character font in the group buffer 18 in the user font definition storage unit 14. At this time, the group buffer 1
The reference position in 8 and the base part position in the group are combined to determine the position of each base part, and the same is done for the magnification and registered in the user font definition storage unit 14. With this, the external character font has the same data structure (part number,
(Position, magnification), the data amount is very small.

In the above embodiment, the external characters are all created by assembling the base parts which are the built-in character components. Therefore, the symbols and the like having the non-incorporated parts should be created with the external characters. Can not. Therefore, if a user base parts library is further provided to assemble base parts arbitrarily created by a user, all symbols, figures, and the like can be created as external characters.

According to the present invention, existing character fonts can be displayed, necessary vector parts can be grouped from among them, the position and size can be changed, and these can be combined to create an external character. You can easily select character components and check the balance of bias, which is a component part of the entire existing character font, and group the necessary parts and easily change the position and size of bias, etc. Because external characters can be created, external characters can be easily created.
