Abstract

PURPOSE:To arrange a type row in a well-balanced state by adjusting the mutual intervals between types. CONSTITUTION:Front packing quantity Wf1 and rear packing quantity Wr1 showing width before and behind the net image part in an imaginary type frame are operated with respect to each selected type by a type packing quantity operation device. A composing apparatus determines the coordinates of each type on the basis of the calculated values and a type interval. It is unnecessary to preliminarily calculate the front and rear packing quantities Wf1, Wr1 with respect to each type and both quantites are calculated from type image data such as font data showing a type image. As a result, the spaces before and behind the net image part of each type can be equally arranged.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic typesetting device, and more particularly, to an electronic typesetting device capable of adjusting a character space of a character string.

[0002]

2. Description of the Related Art In an electronic plate making process, an electronic typesetting device is used for arranging a group of characters typed by a typesetting device on a block original. The process of arranging a character group on a block copy document is generally called "flowing". A conventional electronic typesetting device has a function of setting a space between characters for setting an equal interval between characters. The data representing the image of each character represents an image in which the image portion of the character is arranged in a predetermined virtual character frame. In addition, all characters used in typesetting usually have the same virtual character frame. The character spacing setting function in the conventional electronic typesetting device has been a function of setting the interval between virtual character frames.

[0003]

However, since the width of the net image portion is considerably different between the character "1" and the character "a", the character spacing before and after the character "1" can be reduced by the conventional character spacing setting. The space between the characters looks relatively wide, while the space between the characters before and after the character “a” looks relatively narrow. Therefore, there is a problem that the character strings cannot be well balanced.

The present invention has been made to solve the above-mentioned problems in the prior art, and provides an electronic typesetting device capable of arranging character strings in a well-balanced manner by adjusting the space between characters. The purpose is to

[0005]

In order to solve the above problems, an electronic typesetting apparatus according to the present invention is provided with a character size data indicating the size of a character frame of a character to be typed and a net image portion of each character. Typesetting information input means for inputting typesetting information including character spacing data indicating mutual intervals, character type input means for inputting a character string, and characters for storing character image data of a plurality of prepared characters Image data storage means, and position calculation means for calculating the position of the net image portion in the character frame based on the character image data stored in the character image data storage means for each character of the selected character string. And the mutual spacing of the net image parts of each character,
And a typesetting executing means for setting based on the interval indicated by the character spacing data, and thereby determining the arrangement of the selected characters.

[0006]

Since the position calculation means calculates the position of the net image portion of each character, and the typesetting execution means sets the mutual distance between the net image portions of each character based on the distance indicated by the character space data. You can adjust the space between each character in a good balance.

FIG. 1 is a block diagram showing an electronic typesetting apparatus as an embodiment of the present invention. This electronic typesetting device is C
The PU 10 and the bus line 12 are provided, and the bus line 12 includes a typed data memory 16, a typesetting information memory 18, a character closing amount calculation device 20, a typesetting device 22, and a typeset data memory 24. Are connected. A keyboard 30, a mouse 32, and a digitizer 34 are connected to the bus line 12 as an input device, and a color CRT 36 is connected as an output device. Further, a magnetic disk 38 is connected as an external storage device. The magnetic disk 38 stores font data representing a character image.

The typesetting information inputting means and the character writing means in the present invention are realized by the keyboard 30.
The character image data storage means is realized by the magnetic disk 38, the position calculation means is realized by the character closing amount calculation device 20, and the typesetting execution means is realized by the typesetting device 22.

FIG. 2 is a flow chart showing the procedure of the typesetting work in this embodiment. In step S <b> 1, the operator uses the keyboard 30 to input the character-giving data name of the character-grating data that has been character-gathered with the keyboard 30 in advance. FIG. 3 is a conceptual diagram showing the character collection data stored in the character collection data memory 16. One set of character data includes a character data name and a 2-byte code of a character that has been character-generated.

In step S2, the operator inputs the typesetting information using the keyboard 30. FIG. 4 is a conceptual diagram showing the typesetting information stored in the typesetting information memory 18. Typesetting information includes typeface (Mincho, Gothic, etc.), character size (series, 1st grade = 250 μm), character angle, typesetting direction, character spacing (character spacing), number of lines, number of lines, number of columns, etc. Contains the data of. In step S3, the digitizer 34 is used to instruct the typesetting start point on the screen of the color CRT 36. The relationship between the typesetting start point and the character position will be described later. In step S4, the character filling amount calculation device 20 reads from the character writing data memory 16 2-byte data for one character from the character writing data specified in step S1, and further, the font of the typeface specified by the typesetting information. The data of the character is read from the data.

In step S5, the character padding amount calculation device 20 calculates the leading padding amount and the trailing padding amount of the character read in step S4. FIG. 5: is explanatory drawing which shows the amount of closing of the character "KU". As shown in FIG. 5A, the net image portion (hatched portion) of the character “KU” is a closed loop vector in which n contour points P1 to Pn existing in the virtual character frame VF are connected. Represented by. The font data shown in FIG. 5B is vector data including the coordinate values of each contour point, and is a so-called outline font. In addition,
The virtual character frame VF is a square having a length L on one side, and the origin of the coordinates of each contour point is the origin O (upper left point) of the virtual character frame VF. The length (number of pixels) of one side of the virtual character frame VF is, for example, about 1000. The amount of padding is different between horizontal writing mode and vertical writing mode, but is calculated as follows. (1) In horizontal composition Front filling amount = xm (xm is the minimum x coordinate of contour points P1 to Pn) Rear filling amount = L−xu (xu is the maximum x coordinate of contour points P1 to Pn) (2 ) In case of vertical assembly Front filling amount = ym (ym is the minimum value of y coordinate of contour points P1 to Pn) Rear filling amount = L-yu (yu is maximum value of y coordinate of contour points P1 to Pn) Below, mainly An example of horizontal writing will be described.

The above is a method for calculating the amount of padding of a character represented by vector data, but the amount of padding can be similarly calculated for a character represented by bitmap data. That is, in the case of bit map data, for example, the maximum value and the minimum value of the coordinates of the pixel whose bit data value is “1” are searched, and the same calculation as above is performed based on these values, thereby reducing the space. The amount can be calculated. Characters registered as external characters are usually represented by bitmap data, but the character filling amount can be calculated in this way.

In step S6, the typesetting device 22 determines the coordinates of the characters after typesetting. FIG. 6 is an explanatory diagram showing the filling amount of characters and the coordinates after typesetting. In FIG. 6A, the leading padding amount Wfi and the trailing padding amount Wri of each character are calculated in step S6. FIG. 6B shows the arrangement of characters when the space G is 0, and FIG. 6C shows the arrangement of characters when the space G is not 0. The coordinate X1 of the arrangement point RP1 (lower left point of the character frame) of the first character "KU" is calculated as follows. X1 = Xs−Q × Wf1 / L (1) Here, Xs is the X coordinate of the typesetting start point ST, Q is the size of the character designated by the typesetting information, and Wf1 is the leading justification amount of the first character,
L is the size of the virtual character frame.

When the character gap G is 0, the arrangement point of each character after the second character "su" is calculated as follows. Xi = Xi-1 + Q * (L-Wri-1) / L-Q * Wfi / L (2) where Xi is the X coordinate of the i-th character and Wri-1 is (i-
1) The trailing padding amount of the character, Wfi is the leading padding amount of the i-th character. When the first character is arranged according to the expression (1) and the second character is arranged according to the expression (2), the arrangement shown in FIG. 6B is obtained.

On the other hand, when the character gap G is not 0, the following expression (2a) is used instead of the expression (2). Xi = Xi-1 + Q * (L-Wri-1) / L-Q * Wfi / L + G (2a) FIG. 6 (c) shows the result of arrangement according to the equation (2a).

Returning to FIG. 2, in step S7, it is determined whether or not the arrangement has been determined for all the characters included in the character-gathering data. If not completed, the process returns to step S5 and steps S5 to S7 are repeated. This determines the placement for all characters in the string. The formatted data indicating the image of the character string after the formatting is stored in the formatted data memory 24. FIG. 7 is an explanatory diagram showing the contents of the formatted data memory 24. In the formatted data memory 24,
The character code of each character of the character string, the coordinates of the lower left point of the character frame, and the typesetting information are stored. The formatted character image is reproduced based on the formatted data.

According to the above-described embodiment, the leading and trailing padding amounts of the characters that have been picked up are calculated, and based on these values, the mutual distance between the net image portions of the characters is made equal to the character gap G. Since it is set, it is possible to evenly arrange the spaces before and after the net image portion of each character by appropriately specifying the value of the character gap G. Further, since the leading padding amount and the trailing padding amount are calculated by the character padding amount calculation device 20 based on the font data of the characters, it is not necessary to calculate the leading padding amount and the trailing padding amount for each character in advance. In particular, since one set of Japanese typefaces contains several thousand characters, it takes a considerable amount of time and effort to calculate the amount of filling characters in advance. However, in the above embodiment, it is not necessary to calculate the amount of filling characters in advance. , It has the advantage that you can adjust the balance of character strings without much time and effort.

The present invention is not limited to the above-described embodiments, but can be carried out in various modes without departing from the scope of the invention, and the following modifications can be made. (1) In the above embodiment, the character padding amount calculation device 20 calculates the leading padding amount and the trailing padding amount of each character. However, instead of calculating the leading padding amount and the trailing padding amount, a virtual character frame is drawn for each character. Other types of data that represent the position of the net image portion in may be obtained. For example, as shown in FIG. 8, the x coordinate xm of the starting point of the net character image portion and the width Ln of the net character image portion based on the origin O of the virtual character frame VF are defined as
It may be used instead of the front-packing amount and the back-packing amount.

(2) In the above embodiment, the mutual distance between the net image portions of the respective characters is set to be equal to the character gap G. However, the actual distance may be the character gap G plus a predetermined margin. . Further, a value obtained by multiplying the character gap G by a predetermined ratio may be set as the actual interval. That is, the mutual distance between the net image portions of the respective characters may be set based on the distance indicated by the character spacing data of the typesetting information.

[0020]

As described above, according to the electronic typesetting apparatus of the present invention, the position calculating means calculates the position of the net image portion of each character, and the typesetting executing means calculates the net image portion of each character. Since the mutual intervals are set based on the intervals indicated by the inter-character data, it is possible to adjust the character strings in a balanced manner.
