Description

Detailed Description of the Invention

[0001]

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 for arranging characters and figures along arbitrary lines.

[0002]

2. Description of the Related Art In an electronic plate making process, an electronic typesetting device is used for arranging a character string under a block. The conventional typesetting device has a function of arranging a character string on a straight line. However, depending on the printed matter, there is a case where it is desired to produce visual interest by arranging a character string along a curved line, for example.

[0003]

However, in the conventional typesetting device, it is difficult to arrange a character string along a curved line because the character string can only be arranged on a straight line. Therefore, conventionally, an operator manually pastes characters of a character string one by one along a curved line on a blockboard, which requires a considerable amount of time and effort.

The present invention has been made to solve the above-mentioned problems in the prior art, and an object thereof is to provide an electronic typesetting apparatus capable of arranging characters along arbitrary lines.

[0005]

In order to solve the above-mentioned problems, a first electronic typesetting device according to the present invention has at least a first input means for inputting a character string, and an arrangement of the character string. A reference line designating means for designating a layout reference line of an arbitrary shape, a second input means for designating an array specification for arranging the character string along the layout reference line, and according to the array specification. The size of each character of the character string is determined, and the position of each character along the arrangement reference line is determined based on the size of each character, and each character of the character string is set to the arrangement reference line. And a typesetting execution unit arranged along the line.

A second electronic typesetting device of the present invention is
First input means for inputting an image element in which characters and graphics are combined, reference line designating means for designating an arrangement reference line of an arbitrary shape for arranging the image element, and the arrangement reference line Second input means for designating an array specification for repeatedly arranging the image elements along the line, and the size of each image element repeatedly arranged according to the array specification, and determining the size of each image element. Based on the arrangement reference line, a position for repeatedly arranging the image element is determined, and a typesetting execution unit that repeatedly arranges the image element along the arrangement reference line is provided.

[0007]

In the first electronic typesetting device, the position of arranging each character of the character string on the arrangement reference line is determined, and each character is arranged in an arbitrary shape by associating the virtual line with the arrangement reference line. Since the character strings are arranged on the reference line, the character strings can be arranged along a line having an arbitrary shape.

Further, in the second electronic typesetting apparatus, the position where the image element is repeatedly arranged on the arrangement reference line is determined, and the image element is repeatedly arranged on the arrangement reference line of an arbitrary shape, so that the character and the graphic are combined. The containing image elements can be repeatedly arranged along a line of any shape.

【Example】

A. Embodiment in which Only Character Strings are Arranged FIG. 1 is a block diagram showing an electronic typesetting device as an embodiment of the present invention. This electronic typesetting device has a CPU 10
And a bus line 12, the bus line 12 includes a graphic data memory 14 and a character writing data memory 16
The typesetting information memory 18, the typesetting device 20, and the typeset data memory 28 are connected to each other. The bus line 12 has a keyboard 30 and a mouse 32 as input devices.
And a digitizer 34 are connected, and a color CRT 36 is connected as an output device. Further, a magnetic disk 38 is connected as an external storage device. The typesetting device 20 includes a vectorization executing means 22, a magnification calculating means 24, and a typesetting executing means 26. These means are realized by a software program executed by the CPU 10.

2 and 3 are flow charts showing the procedure of the typesetting work in this embodiment. Step S
In 1, the operator uses the digitizer 34 to create a placement reference line. FIG. 4 is an explanatory diagram showing a region PR of a photographic image drawn on a block and an arrangement reference line RL. The operator traces the placement reference line RL with the digitizer 34 to input graphic data representing the placement reference line RL.

In step S2, the operator designates the range of the character string to be typeset. FIG. 5 is an explanatory diagram showing a character string in which characters have been set in advance. The operator selects at least a part as a character string to be typeset from the character strings that have been preliminarily typed and displayed on the color CRT 36.

In step S3, an array specification of character strings is input. Here, the array specification is a specification indicating any one of the following three array methods. (1) Inclined typesetting: Characters are arranged on the arrangement reference line RL while sequentially changing their sizes. When using this arrangement method, specify the size of the first character and the size of the last character of the character string. (2) Even typesetting: Character strings are arranged uniformly over the entire length of the arrangement reference line RL. At this time, the size of the characters is adjusted so that they can be arranged evenly. (3) Normal typesetting: Character strings are arranged in a predetermined size along the arrangement reference line RL.

In step S4, vectorization executing means 2
2 divides the arrangement reference line RL into minute line segments to form a multi-vertex figure. This process is generally called vectorization.
Here, the multi-vertex figure refers to a figure formed by sequentially connecting a plurality of straight line segments. The multi-vertex figure has a type that forms a closed region like a polygon figure, and the placement reference line R in FIG.
There is a type such as L that does not form a closed region. The graphic data of the arrangement reference line RL as a multi-vertex graphic is stored in the graphic data memory 14.

FIG. 6 is a conceptual diagram showing the data of the arrangement reference line RL stored in the graphic data memory 14. As the figure, in addition to the multi-vertex figure, there are straight lines, arcs and the like. FIG. 7 is an enlarged view showing an arrangement reference line RL which is vectorized and is composed of a plurality of vertices P1 to P11.

In step S5, the typesetting execution means 26 calculates the length Li and the total length L of each line segment of the arrangement reference line RL based on the coordinate data of the vertices P1 to P11 of the arrangement reference line RL. Next, in step S6 of FIG.
The typesetting executing means 26 determines whether the array specification input in step S1 is inclined typesetting, uniform typesetting, or normal typesetting, and executes any one of steps S7, S8, and S9.

In the case of inclined typesetting (step S7), first, the magnification calculating means 24 calculates the bias value B according to the following equation. B = {(series of ending character)-(series of starting character)} / (number of characters) Here, the series of characters is a unit representing the size of the character, and the first class corresponds to 0.25 mm. The series K (i) of the i-th character in the character string is calculated according to the following equation. K (i) = (series of start character) + INT (B · i) where INT represents an operation that takes only the integer part of the numerical value in parentheses.

The typesetting executing means 26 determines the position of each character on the virtual straight line based on the size of the character thus obtained. The virtual straight line is a line segment having the same length as the total length L of the arrangement reference line RL. Figure 8
(A) is a figure which shows the character string arrange | positioned on the virtual straight line by the process of step S7. As a result of the processing in step S7, the series of each character and the position of the lower left point (indicated by a white circle in the figure) of each character are determined. The position of the lower left point is represented by the distance from the starting point IP of the straight line. This distance corresponds to the distance from the starting point P1 of the arrangement reference line RL.

In the case of uniform typesetting (step S8), the magnification calculating means 24 calculates the series K of each character according to the following equation,
The typesetting executing means 26 determines the position of each character on the virtual straight line. K = INT {(total length L of placement reference line) / (number of characters)}

FIG. 8B is a view showing character strings arranged on a virtual straight line for uniform typesetting and normal typesetting. However, the size of each character is different between the uniform typesetting and the normal typesetting. Also in the uniform composition and the normal composition, the size of each character and the position of the lower left point of each character on the virtual straight line are determined.

Steps S10 to S13 are executed by the typesetting executing means 26. In step S10, the cumulative length TL for obtaining the actual position of each character on the arrangement reference line RL is initialized to zero. In step S11, the position and the angle of each character on the arrangement reference line RL are obtained corresponding to the position of each character on the virtual straight line. Figure 9
[Fig. 6] is an explanatory view showing a character string arranged on the arrangement reference line RL in normal typesetting. As shown in FIG. 9, the starting point IP of the virtual straight line is associated with the starting point P1 of the arrangement reference line RL, and the lower left point (white circle) of each character is determined according to the distance measured from the starting point P1 along the arrangement reference line RL. Position) is determined. Further, the angle θ of each character is set equal to the angle of the line segment where the lower left point of each character exists.

In step S12, the position and angle of the lower left point of the character obtained in step S11 is the typesetting information memory 1
Registered in 8. FIG. 10 is an explanatory diagram showing data registered in the typesetting information memory 18. In step S13, it is determined whether or not all the characters in the character string have been processed. If not, the process returns to step S11, and the processes of steps S11 and S12 are executed for the next character.

As described above, in this embodiment, the character strings are arranged on the virtual straight line according to the specified array specification,
The position and angle of each character on the placement reference line are determined by associating this virtual straight line with the placement reference line. Therefore, the character strings can be easily arranged on the arrangement reference line of an arbitrary shape with various arrangement specifications.

B. Example in which characters and figures are arranged In the second example, image elements in which characters and figures are combined are repeatedly arranged along the arrangement reference line. The apparatus in the second embodiment is the same as that in the first embodiment, and only the function of each means in the typesetting apparatus 20 is different. FIG. 11 is a flowchart showing a processing procedure in the second embodiment.

In step S21, the arrangement reference line RL is created. This is the same process as step S1 in FIG. In step S22, the operator inputs a character and a graphic, and the original image element for copying (hereinafter
(Called “original image element”). FIG. 12 is a diagram showing an original image element including a circle, a triangle, and a character “Ai”. In step S23, the operator uses the mouse 32 to indicate the position of the reference point RP of the original image element (FIG. 12).
reference). In step S24, the operator instructs the number of times of copying and the magnification. For example, when arranging one original image element and two copies, the number of copies is designated as twice, the magnification of the first copy is designated as 70%, and the magnification of the second copy is designated as 50%. However, the magnification may specify the same value for all the copies.

In step S25, step S4 in FIG.
Similarly, the vectorization executing means 22 converts the arrangement reference line RL into a minute line segment. In step S26, the typesetting execution means 26 calculates the total length L of the arrangement reference line RL, and the step S26
The copying interval is calculated by dividing the total length L by the number of times of copying designated in 24 (two times in this embodiment).

In step S27, the typesetting executing means 26 calculates the position and angle of the image element on the arrangement reference line RL. FIG. 13 is a diagram showing the positions of the arrangement reference line RL and the arrangement points RP1 to RP3 of the three image elements. A reference point RP (see FIG. 12) of the image element is arranged at each of the arrangement points RP1 to RP3. In this example, the number of copies is two, so the distance obtained by dividing the arrangement reference line RL by 2 is the distance between the image elements. The angle of the image element depends on each placement point RP
It is set to be equal to the angle θ of the line segment of the arrangement reference line RL in 1 to RP3.

In step S28, the magnification calculation means 24 enlarges or reduces the original image element by the designated magnification, and arranges the image element at positions RP1 to RP3 on the arrangement reference line RL. However, one image element to be processed is arranged in step S28.

FIG. 14 is a diagram showing a scale-converted image element. In the magnification conversion, the coordinates (Xc, Yc) of the respective coordinate points Q1 to Q4 of the figure and the lower left points Q5 to Q7 of the character are converted according to the following formulas to obtain the converted coordinates (Xc, Yc).
Is required. Xc = X + (X-Xr) * Yc = Y + (Y-Yr) * M Here, (Xr, Yr) is the coordinate of the reference point RP, and M is a magnification. Further, the length and size of the radius r1 of the circle and the series of characters are converted according to the following equation. LLc = LL · M where LL is the length before conversion and LLc is the length after conversion.

In step S29, it is determined whether or not the processing has been completed for all image elements. If not, steps S27 and S28 are repeated,
The next image element is placed on the placement reference line RL. Figure 15
FIG. 8 is a diagram showing image elements arranged at the respective arrangement points RP1 to RP3 in this way.

In the above embodiment, the position of the reference point of each image element to be copied is obtained on the arrangement reference line RL, and each image element is arranged at the position of the reference point according to the designated magnification. There is an advantage that image elements having different magnifications can be easily arranged along an arbitrary line. The image arranged as shown in FIG. 15 has a color CRT 36.
Is displayed on the color CRT 36, the operator can immediately check the image on the color CRT 36 and can correct it if necessary.

16 and 17 are flow charts showing the processing procedure when either one of the sawtooth line and the wavy line can be selected as a figure. Step S3
In 1, the operator inputs an arrangement reference line, as in step S21 of FIG. In step S32, the operator inputs a character string to be a copy source. Step S
At 33, the position of the reference point of the saw line or the wavy line with respect to the character string is designated. FIG. 18 is a diagram showing the position of the character string “A” (one character in this example) and the reference point RP. FIG. 18A shows the case of a saw wire, and FIG.
(B) shows the case of a wavy line.

In step S34, the operator selects the sawtooth line or the wavy line, and instructs the number of times of copying and the magnification of each copy. The number of copies referred to here is the number of peaks of a saw line or a wavy line. In step S35, the height h of the amplitude is designated. The height h of the amplitude is the height of the peak of the saw line or the wavy line (see FIG. 18).

Steps S36 to S39 are processes corresponding to steps S25 to S28 of FIG. 11, respectively. In step S36, the arrangement reference line RL is converted into a minute line segment. In step S37, the total length of the arrangement reference line RL is obtained, and the distance between the reference points of the saw line or the wavy line is obtained according to the number of copies.

In step S38, the position and angle of the character string on the placement reference line are calculated. Here, the position of the character string is the position where the reference point RP shown in FIG. 18 is arranged. In step S39, the character string is enlarged or reduced at the designated magnification and is arranged at the arrangement point on the arrangement reference line RL. FIG. 19 is a diagram showing characters arranged along the arrangement reference line RL. However, in this example, the magnification of all character strings is 100%.

In step S40, as shown in FIG. 20, the position of the apex PP of the mountain of the saw or wavy line is determined based on the current position of the placement point RP1, the position of the next placement point RP2, and the amplitude h. To do. FIG. 20 (a) shows the saw wire thus obtained, and FIG. 20 (b) shows the wavy line. Note that the peaks may be arranged on one side of the arrangement reference line RL as shown in FIG.
As shown in (b), peaks may be arranged alternately on both sides of the arrangement reference line RL.

The sawtooth line or wavy line figure data thus created is registered in the figure data memory 14 in step S41. Note that steps S38 to S41
Creates a mountain of saw or wavy lines. In step S42, it is determined whether or not a sawtooth line or a wavy line has been created for the entire length of the placement reference line RL. If not, the process returns to step S38 and the processes of steps S38 to S41 are repeated.

As described above, in the above embodiment, the arrangement reference line and the character string are designated, the saw line or the wavy line is selected, and the character string and the mountain of the saw line or the wavy line are selected along the arrangement reference line. Since it is repeatedly copied and arranged repeatedly, it is possible to easily combine a figure having a large number of repetitions such as a saw line or a wavy line with a character string and to arrange it along an arbitrary line.

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-described embodiment, the operator inputs the placement reference line using the digitizer 34. However, for example, a figure drawn on the blockboard is read and a part of the line is used as the placement reference line. May be.

(2) In the above embodiment, the processing is performed by the vector for converting the arrangement reference line RL including a curve into a minute line segment. However, a geometric curve such as an arc is converted into a minute line segment. Instead, the characters and figures may be arranged as they are as geometric curves. This is because if it is a geometric curve, the distance on the curve can be calculated. When the arrangement reference line RL includes an arc, the angle of the character arranged on the arc is set equal to the angle of the tangent line of the arc at the lower left point of the character. However, if vectorization is performed as in the above-described embodiment, the distance on the arrangement reference line is relatively easy to calculate, which has the advantage of shortening the processing time.

[0040]

As described above, in the first electronic composition apparatus of the present invention, the position where each character of the character string is arranged on the arrangement reference line is determined, and the virtual straight line and the arrangement reference line are associated with each other. Since each character is arranged on the arrangement reference line of an arbitrary shape by adding, there is an effect that a character string can be arranged along a line of an arbitrary shape.

Further, in the second electronic typesetting apparatus, the position where the image element is repeatedly arranged on the arrangement reference line is determined, and the image element is repeatedly arranged on the arrangement reference line having an arbitrary shape. There is an effect that the image elements to be included can be repeatedly arranged along a line having an arbitrary shape.
