DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filling table creating apparatus for creating a filling table in which a filling amount indicating a space which can be deleted around a net image portion is registered for characters used for typesetting. .

[0002]

2. Description of the Related Art In an electronic plate making process, an electronic typesetting device is used for arranging a character group obtained by a typesetting device on an underprint document. The process of arranging a character group on a composition document is generally called “flowing”. The electronic typesetting device has a character spacing setting function for setting a uniform interval between characters. The data representing the image of each character is
It shows an image in which a character image portion is arranged in a predetermined virtual character frame. All characters used in typesetting usually have the same virtual character frame.

However, for example, the characters "1" and "A"
Since the width of the net image part is quite different between and, with the normal character setting, the space between the characters before and after the character "1" looks relatively wide, while the character before and after the character "a" Appear relatively narrow. In order to solve this problem, there is a method of presetting a character clogging amount indicating a width of a space that can be reduced around a net image portion of each character. FIG. 1 is an explanatory diagram showing the amount of character clogging. For the character "1", the vertical and horizontal left and right filling amounts Wt, Wb, Wf
, Wr are set. The portion of the character filling amount can be reduced, and the rectangular area indicated by the broken line in FIG. 1 is the minimum area of the character “1”. When such a character filling amount is used, when creating a shape (ie, font) of a character image, an operator sets the character filling amount in advance for each character, and indicates a correspondence between the character filling amount and each character. I was creating a filling table.

[0004]

However, since the amount of clogging of each character is generally different, an operator must individually determine the amount of clogging for all characters in one typeface. There was a problem that it required considerable space and time. The present invention has been made in order to solve the above-described problem in the related art, and has an object to provide a filling table creating apparatus that can easily create a filling table in which the filling amount of characters is registered. Aim.

[0005]

In order to solve the above-mentioned problems, a character filling table creating apparatus according to the present invention stores character image data representing a character image of each character for a plurality of characters of at least one typeface. Character image data storage means, input means for selecting one of the typefaces stored in the character image data, and, for each character of the selected typeface, the character image data stored in the character image data storage means. Based on the calculated width of the margin between the net image portion of each character and a predetermined character frame of each character,
A predetermined coefficient common to a plurality of characters of the selected typeface
Is multiplied by the width of the margin to calculate the amount of clogging of each character, the amount of clogging of each character calculated by the clogging amount calculation means, the character code of each character, Table creation means for creating a character filling table including typeface data indicating a typeface.

[0006]

[Function] For each character of the selected typeface , multiply the margin width between the net image part and the character frame by a certain coefficient.
Since calculating the shape packed amount by the operator does not need to specify the Jitsume amount for each character, a character packed table having registered the character packed amount of characters can be easily created.

[0007]

FIG. 2 is a block diagram showing an embodiment of a filling table creating apparatus according to the present invention. This filling table creation device includes a CPU 10 and a bus line 12, and the bus line 12 includes a ROM 14, a RAM 1
6, a filling amount calculating device 20, a filling table memory 22
And are connected. A keyboard 30, a mouse 32, and a digitizer 3 are provided as input devices on the bus line 12.
4, 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 character image data storage means in the present invention is realized by a magnetic disk 38. The input means is realized by the keyboard 30, the filling amount calculating means is realized by the filling amount calculating device 20, and the table creating means is realized by the CPU 10.

FIGS. 3 and 4 are flowcharts showing the procedure of the typesetting operation in this embodiment. Step S
In step 1, the operator inputs a typeface file name specifying a typeface from the keyboard 30. In step S2, the operator inputs a font coefficient K from the keyboard 30. The typeface coefficient K is a value used when determining the amount of clogging,
How to use it will be described later.

Steps S3 to S8 are steps for calculating the amount of clogging for each character of the designated font and creating a clogging table. In step S3, data for one character is read from the magnetic disk 38 from the font data file of the font specified in step S1, and stored in the RAM 16. The font data in this embodiment is vector data expressing a net image portion of a character as a vector, and is called a so-called outline font.

In step S4, the maximum value and the minimum value of the coordinate values of the contour points of the vector data of the read character are obtained. FIG. 5 is an explanatory diagram showing the vector data of the character "". The vector data of the character “ki” includes a first closed-loop vector composed of m contour points P1 to Pm, and n
A second closed loop vector including the contour points Q1 to Qn is included. FIG. 6 is a conceptual diagram showing a configuration of character vector data. Vector data of one character includes a character code (2-byte code), the number of closed loops, the number of contour points forming each closed loop vector, and the coordinate value (x, y) of each contour point. In step S4, the filling amount calculating device 20 determines the maximum values xmax and ymax and the minimum values xmin and ymin from these coordinate values. In FIG. 5, the circumscribed rectangle CR of the net image portion (hatched portion) of the character is the maximum value xmax, yma
x and the minimum values xmin, ymin.

In step S5, the maximum values xmax, ymax
And the minimum values xmin and ymin are used to determine the upper, lower, left and right margin values (width of the margin) of the net image portion. Upper margin value = L-ymax Lower margin value = ymin Left margin value = xmin Right margin value = L-xmax where L is the length of one side of the virtual character frame VF. Here, the lower left point of the virtual character frame VF is set as the coordinate origin O.

In step S6, based on the above margin value,
The character clogging amount is calculated according to the following equation. Upper character filling amount Wt = K × (upper margin value) × 100 / L = K (L−ymax) × 100 / L (%) Lower character filling amount Wb = K × (lower margin value) × 100 / L = K (Ymin) × 100 / L (%) Left character filling amount Wf = K × (Left margin value) × 100 / L = K (xmin) × 100 / L (%) Right character filling amount Wr = K × (Right margin) Value) × 100 / L = K (L−xmax) × 100 / L (%) As can be understood from these equations, the amount of character filling is represented by a ratio (percentage) to the length L of one side of the virtual character frame VF. Have been. The typeface coefficient K is a value commonly applied to all characters included in one typeface, and is set to a desired value of 1 or less (for example, 0.8).

The reason why the amount of filling is defined by the ratio to the virtual character frame VF is that the absolute value of the amount of filling can be easily obtained at the time of typesetting. That is, in the typesetting processing, the actual size of the character is specified separately from the general length L of the virtual character frame VF. As described above, if the filling amount is defined as a ratio to the virtual character frame VF, the absolute value of the filling amount at the time of typesetting can be obtained by multiplying the designated character size by the filling amount.

FIG. 7 is an explanatory diagram showing the minimum character area MR defined by the character clogging amount calculated as described above.
That is, in the typesetting processing, adjacent characters can be brought close to each other until the minimum character region MR touches. Since the minimum character region MR is larger than the circumscribed rectangle CR of the net character image, even when the character strings are brought close to each other until the minimum character region MR touches, the net image portions of adjacent characters may touch each other. Can be prevented. If the typeface coefficient K is set to a numerical value less than 1, there is an advantage that net character portions can be prevented from contacting each other.

In a step S7, the calculated amount of filling is registered in the filling table memory 22. FIG. 8 is an explanatory diagram showing a character filling table registered in the character filling table memory 22. In the filling table, a font code indicating a font, a character code indicating a character, and four filling amounts are registered.

Returning to FIG. 3, in step S8, it is determined whether the processing has been completed for all the characters of the font selected in step S1, and if not, step S8 is performed.
3 and repeat the processing of steps S3 to S8. With the above processing, the amount of clogging is obtained for all the characters of one font, and a clogging table is created.

Next, in step S9 of FIG. 4, a character string is displayed on the color CRT 36 with the minimum character area MR of each character in contact. The operator observes the displayed character string and determines in step S10 whether or not it is necessary to change the character clogging amount. If it is necessary to change the character filling amount, the character filling table shown in FIG. 8 is displayed on the color CRT 36 in step S11, and the character filling amount of the desired character is changed. Thereafter, the process returns to S9, and the character string is displayed again according to the changed character filling amount. By repeating steps S9 to S11, it is possible to make adjustments so as to obtain an optimal amount of character filling. Steps S9 to S11 may be performed as needed, and may not be performed.

According to the above embodiment, one typeface coefficient K is used for all characters in one typeface, and the amount of character clogging is calculated by multiplying the net image margin by the typeface coefficient K. A filling table can be created easily and quickly. Further, if the apparatus of the above embodiment is used, creation of character image data has already been completed, and even for a typeface whose data does not include a filling table, there is an advantage that a filling table can be easily created. is there.

The present invention is not limited to the above-described embodiment, but can be implemented in various modes without departing from the gist of the present invention. For example, the following modifications are possible. (1) In the above embodiment, the amount of character clogging is represented by the ratio to the length L of one side of the virtual character frame VF. Instead, it is represented by another value such as the number of pixels in the virtual character frame VF. May be. However, the length L of one side of the virtual character frame VF
Expressing the ratio in terms of the ratio of the character size to the designated character size has the advantage that the absolute value of the character size at the time of typesetting can be obtained by multiplying the character size by the character size.

(1) In the above-described embodiment, the amount of clogging is calculated by multiplying the font coefficient K by the margin value. However, the amount of clogging may be calculated by another calculation. For example, the character clogging amount may be obtained by adding a predetermined value to the margin value.

[0022]

As described above, according to the character filling table creating apparatus of the present invention, the width of the margin between the net image portion and the character frame is calculated for each character of the selected typeface. Since the amount of clogging is calculated by multiplying the width of this margin by a certain coefficient , the operator does not need to specify the amount of clogging for each character. The effect is that it can be created.
