FIG. 2 is a block diagram showing an electronic typesetting device as an embodiment of the present invention. The electronic typesetting device includes a CPU 10 and a bus line 12, and the bus line 12 includes a graphic data memory 14, a character writing data memory 16, a typesetting information memory 18, an area extraction computing device 20, The typesetting device 22 and the typeset data memory 24 are connected. A keyboard 30 and a mouse 32 are connected to the bus line 12 as input devices, and a color CRT 36 is output as an output device.
Are connected. Further, a magnetic disk 38 is connected as an external storage device. The area designating means in the present invention is realized by the mouse 32.
The keyboard 30 is used as the character-writing means, the area extraction arithmetic unit 20 is used as the feasible area recognition means, and the typesetting apparatus 22 is used as the flow-in execution means.

FIG. 3 is a flow chart showing the procedure of the typesetting work in this embodiment. In step S1, the operator uses the mouse 32 to specify a figure in the pouring area. FIG. 4 (a) shows a pouring area CR on the block BC.
It is explanatory drawing which shows the state in which was designated. Pour area C
The position and size of R are specified by specifying the positions of two points U1 and U2 on the diagonal line and the angle θ of the pouring region CR. The pouring region CR is a rectangle having a width Wr and a length Lr.

In step S2, the operator operates the mouse 3
2 is used to specify a figure (also called a “block figure”) in the flow-in prohibition region PR. Figure 4 (b) shows a block copy B
FIG. 6 is an explanatory diagram showing a state in which a flow-inhibited area graphic (mixed graphic of PR1 and PR2) is designated on C. The positions and sizes of the closed figures PR1 and PR2 are specified by designating the positions of the vertices V1 to V8 on their contours. The diameters of the arcs between the vertices V2 and V3 and between V6 and V7 are also specified.

2 for defining the contour of the flow-inhibited area PR
Of the two closed figures PR1 and PR2, the second closed figure PR2
Is included in the first closed figure PR1. in this way,
A figure (area) composed of a combination of a plurality of closed figures, and a figure in which some closed figures are included in other closed figures is called a "mixed figure". As will be described later, the pouring is prohibited by the two closed figures PR1 and PR2.
It is a region surrounded by (that is, a flow-in prohibition region PR). The pouring is not prohibited in the area outside the first closed figure PR1 and the area inside the second closed figure PR2.

A flow-in prohibited region PR (mixed pattern) composed of a flow-in region CR and closed patterns PR1 and PR2
The data for specifying is stored in the graphic data memory 14. FIG. 5 is an explanatory diagram showing data stored in the graphic data memory 14. In the graphic data memory 14, the size of each graphic, the type of the graphic (rectangular, circular, elliptical, mixed graphic, etc.), graphic usage (the graphic of the pouring area, the graphic of the pouring prohibited area, etc.), Graphic data (vertex coordinates, arc diameter, etc.) is stored.

In step S3, the operator designates from which character of the previously selected character group the character is to be poured. FIG. 6 is an explanatory diagram showing a character group stored in the character collection data memory 16. Each character is registered as a 2-byte code. Here, it is assumed that the first character is poured. In addition, when the character collection work is not performed in advance, the character collection work may be performed by inputting a character from the keyboard 30 in step S3. When the typesetting work is performed, the typesetting information shown in FIG.
Be registered with. The typesetting information includes the size of characters, the space between characters,
It includes the number of characters per line, the number of lines, and the number of columns. In step S4, the operator presses the typesetting start button. This button is used to select a certain key on the keyboard 30 or color CR
It is realized as a selection branch displayed on T36.

Steps S5 to S9 are operations automatically performed by the electronic typesetting device. First, in step S5, the area extraction arithmetic unit 20 extracts one row of rectangles from the flow area CR. FIG. 8 is a flowchart showing the detailed procedure of step S5, and FIG. 9 is an explanatory diagram showing the flow-in area CRa for one line. In step S51,
The width W1 of one line (corresponding to the height of the character) is determined from the size of the character stored in the typesetting information memory 18. In step S52, the line length Ls is calculated from the character width, the character space, and the number of characters in one line. The length Ls of one line is equal to or less than the length Lr (see FIG. 4A) of the casting region CR. If N type horizontal writing is designated by the typesetting information, N × Ls ≦ Lr. Here, for simplicity, a case where no columns are formed will be described.

Returning to FIG. 3, in step S6, the area extraction arithmetic unit 20 extracts one line of the flowable area, and in step S7, the typesetting device 22 flows in the one line of the flowable area of the set character group. To do. Figure 10
It is a flowchart which shows the detailed procedure of step S6.
In step S61, all the figures are rotated by θ degrees so that the rotation angle of the pouring area CR becomes 0 degree. Figure 11
FIG. 6 is an explanatory diagram showing a flow-in area CRa and a flow-in prohibition area PR for one line after rotation.

In step S62, the pouring prohibited area P
It is determined whether R is a mixed figure and, if it is a mixed figure, whether it is a hollow figure. In the example of FIG. 4B, the clockwise vector graphic PR1 is defined as being filled (pouring is prohibited), and the counterclockwise vector graphic PR2 is being defined as an internal void (do not prohibit pouring). Therefore, by examining the vector directions of the vector figures PR1 and PR2 that form the pouring prohibited area PR, it is possible to determine whether or not the mixed figure is a hollow figure.

In step S63, one figure out of a plurality of closed figures forming the mixed figure is taken out. In FIG. 4B, either closed figure PR1 or PR2 is taken out. In step S64a, as shown in FIG. 11, the intersection point P between the line segment L1 at the upper end of the flow-in area CRa for one line and the contour of the closed figure PR1 forming the flow-in prohibition area PR.
1. Calculate the x coordinate of P4. At this time, the line segment L1 is assumed to be a straight line of infinite length. In step S65, it is determined whether or not the process of step S64a has been completed for all the mixed figures. If not completed for all the mixed figures, the process returns to step S63 to repeat the processes of steps S63 and S64a, and if completed, the process proceeds to step S66. Therefore, here, the x-coordinates of the intersection points P2 and P3 with the contour of the closed figure PR2 are obtained. If it is determined in step S62 that the figure is not a mixed figure, the same process as step S64a is performed in step S64b, and the process proceeds to step S66.

In step S66, x at intersections P1 to P4
Rearrange the coordinates in ascending order. In step S67, n
No pouring is allowed between the (n + 1) th intersection and the (n + 1) th intersection. Here, n is an odd number of 1 or more.

In step S68, steps S62 to S62 are performed for the line segment L2 at the lower end of the flow-in region CRa for one line.
The same processing as 67 is performed to obtain intersections Q1 to Q4 and the range of pouring prohibition. Then, in step S69, the pourable region for one line is determined. Pourable area FR
As shown in the lower part of FIG. 11, 1a, FR1b, and FR2 are portions that are not prohibited to be poured in the length Lr of the casting region Lr.

Returning to FIG. 3, in step S7, the flowable area F for one row extracted in step S6 is fetched.
The typesetting device 22 pours the typesetting into the R1a, FR1b, and FR2. That is, the character groups stored in the character writing data memory 16 can be filled into the areas FR1a and FR1.
It is arranged in 1b and FR2. In step S8, the process moves to the start point of the next line in the flow-in region CR. In step S9, it is determined whether or not all the characters have been poured, and if not completed, the process returns to step S5 and the processes of steps S5 to S8 are repeated.

FIG. 12 is a diagram showing the flowable area FR (hatched) which is determined by the area extraction calculation device 20. As the pourable region, in the pouring region CR, the first type pourable region FR1 that exists outside the outer peripheral contour of the pouring prohibited region PR and the second type that is surrounded by the pouring prohibited region PR are included. The flowable area FR2 is recognized.

FIG. 13 shows two types of pourable areas FR.
It is a figure which shows the state which a part of character group was continuously poured in 1, FR2. In this way, the two types of pourable regions FR1 and FR2 are handled as continuous regions,
It is possible to pour characters continuously.

It is also possible that the user selects at least one of the first-type flowable area FR1 and the second-type flowable area FR2 so that the character group is flowed into only the selected flowable area. is there. Figure 14
An example is shown in which the character group is selectively poured only into the second type flowing area FR2. As described above, by making it possible to select at least one of the two types of flowable regions FR1 and FR2, there is an advantage that the characters can be flowed in various modes according to the preference of the user.

By calculating the pourable area as described above, it is possible to easily carry out the typesetting even for the pouring prohibited area having a complicated shape formed by the mixed figure.

The present invention is not limited to the above embodiments, but can be implemented in various modes without departing from the scope of the invention.
