Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention uses an interactive computer when creating a designated layout sheet from so-called rough manuscripts such as layout instructions and shooting instructions in printing magazines, catalogs and the like. The present invention relates to a method of laying out graphics in a drawing system such as a printing system for which efficiency is improved.

(Technical background of the invention and its problems) In order to create a photo original for printing, it is necessary to create a layout-designating sheet that indicates the layout of the photo and the position of the copy. For this reason, designers, etc.
Arrangement of photographs and letters and photograph contents (layout of subject)
Must be done by hand. Since the design work is inevitably corrected, the work is manually rewritten each time, and conventionally it took a lot of time and labor to obtain the final designated layout paper. That is, FIG. 9 is a magazine,
It shows how to create the layout of today's wide variety of printed materials found in books, catalogs, pamphlets, etc., and is a plan for commercializing various information and planning images.
Based on the above, we will create a shooting instruction document summarizing the details of the meeting such as photo shooting, and put a copy of the explanation and commentary of the specific content while considering the arrangement and shape, and how to create the entire image pattern. A rough manuscript is created by performing a so-called roughing operation 101 in which a layout instruction sheet as to how to construct the product is created and various examinations are performed so as to be appropriate as a product. Based on this rough original, the copy writer 102 creates a text original (copy) 103 that fits within a predetermined space, and typesets it with a phototypesetting machine or the like to form a phototyped character 104. On the other hand, the photographer 108 shoots according to the rough manuscript, creates a color manuscript (photograph) 109, and the designer 105 sets the color manuscript 10
9 and rough manuscript 101 are printed with a design or photograph trimmed to a predetermined size to create a designated paper (design) 106 for layout. After that, these allocation designated paper 106, color originals 109,
After the typesetting letters 104 were collectively collected under the finish man 110, further examined and partially modified,
The typesetting characters 104 are pasted on the mount 111, are made into a block 112 by using a block drawing machine, etc., and are convexly photographed 113, and later become a negative 114. In addition, the layout designated paper 106 and the color original (photo) 109 are instructed by the finish man 110, and the operator 115 causes the scanner 116 to color Y (yellow), M (magenta), C (cyan), and BK (black). After being disassembled, the film 114 is finally synthesized with the negative 114 described above.
At 118, it is sent to the plate making / printing step 119 for printing.

As described above, in the conventional system, not only the rough work of the layout instruction or the shooting instruction in the process of embodying the printed matter from the plan, but also the positioning of the graphic in the layout of the layout-designating paper 106 is manually performed. Therefore, it is strongly desired to improve the efficiency of the relatively monotonous trial and error repetitive work.

(Object of the Invention) The present invention has been made under the circumstances described above.
Based on a rough manuscript such as a layout manuscript or a shooting manuscript when creating a printed manuscript, a layout specification paper can be automatically created by an interactive computer to obtain the final manuscript quickly and accurately. Further, the mount for printing can be created based on these pieces of information, and the shape of the layout graphic can be arbitrarily changed. It is an object of the present invention to provide a graphic layout method in a drawing system such as a printing system.

(Summary of the Invention) The present invention relates to a graphic layout method in a printing system, and includes a menu display section for selecting various command menus and a display screen section for displaying an image corresponding to the contents of the menu. Interactive
In a system for performing layout drawing using a CRT display device, display the created polygon on the display screen, specify the frame change command from the command menu, and specify the side of the desired polygon with the cursor. , By moving the cursor on the specified side above,
By extending the two sides adjacent to the specified side and moving the intersection of the specified side and the two sides adjacent to the specified side,
By making a polygon having the moved intersection point as a vertex a new polygon, the shape of the polygon can be arbitrarily changed.

(Embodiment of the Invention) FIG. 1 is a block diagram showing an embodiment of the present invention. A computer (CPU) 30 for controlling the whole has a function generally called a mini computer. However, it is desirable that basic line drawing can be processed in bit units. A main storage device 31 and an auxiliary storage device 32 such as a floppy disk, a hard disk, an optical disk or the like are connected to the CPU 30 via a bus line, and a TV
An image input device 33 such as a camera, a scanner, or a CCD scanner is connected via an interface 33A. An output device 34 such as an electrostatic plotter, an XY plotter, or a laser beam printer is connected via an interface 34A, and a keyboard 35 for manually inputting necessary data and commands is connected. Further, such an image processing system is connected to a display system of a graphic display via interfaces 36A and 36B, and the display system is provided with a display controller 40 including a microprocessor or the like for controlling the overall display. This display controller 40 has a frame memory 41 and a CRT capable of full-scale display.
Input device such as a display device 42 and a tablet, mouse, light pen, etc. having a function as a man-machine interface
43 and are connected. According to the present invention, under such a configuration, the work of positioning a figure which repeats trial and error in creating the layout-designating paper 106 is computerized to improve the efficiency of the creating work.

In such a structure, in the present invention, first, the layout frame 50 as shown in FIG. 2 is displayed on the CRT display device 42 by a method described later. This display frame 50, as shown,
The desired command menu (eg A10 for copy registration)
Command, copy settings such as A11 command) are provided, and the menu display section 500 allows you to select the desired command with one touch, and the command area A1, A2, A3, ... Display screen section 60 that allows you to perform various tasks interactively
It is divided into 0 and 0. The layout frame 50 can change the size of the menu display unit 500 and the display screen unit 600 to any size as needed.

By the way, when it is necessary to change, correct, move, or delete the display position of the layout figure that has been input and displayed, for example, by lightly touching a desired command menu of the menu display unit 500 with a light pen. (For example, if the command is a split command, touch the A1 command.) Corresponding contents are displayed in color on the display screen 600 or the menu display 500 in real time, and after the desired command work is completed, the output device 34 outputs the 1 to the recording paper 53. Make a hard copy of the layout image for the frame by specifying "Copy" of the A24 command. In this case, the output device
The sizes of the output image of 34 and the display image of the CRT display device 42 are made to correspond one-to-one so that the difference in impression between the image actually hard-copied and the display image is reduced. In addition, all input, selection, and designation operations are performed with the input device 34 and CR.
This is performed by using the command menus A1, A2, A3, ... Displayed on the T display device 42 according to each work flow.

By the way, when drawing and laying out figures on the screen 50,
Especially when drawing a complicated shape such as a polygon, it is very difficult to connect continuously with ruled lines by hand, and it is not possible to change or move the shape of the polygon. It is more difficult and complex. Therefore, in the present invention, the polygon is drawn by designating the vertices of the polygon to be drawn, and the layout drawing is facilitated by changing the shape and moving it easily. I am trying to get to.

Next, the operation will be described in detail with reference to the flowcharts of FIGS.

FIG. 3 is a flowchart for drawing a polygon, and when drawing a polygon is required during the design work (step S1), the "polygon" command (A1
9) is designated (step S2), and then one of the vertices of the polygon is designated (step S3). Then, when the second vertex is designated next (step S4), the space between the start point and the second point is recognized as the first side and is connected as a line (step S5). Similarly, vertices and their edges are formed (step S6), and by finally pressing the end key after designating the nth vertex, the edges between the nth start points are formed (step S7). This completes the polygon. The recognition number is input to this polygon (step S8), and then registered (step S9) to finish.

The process of drawing this polygon will be described as an image 60 in the display screen 600 of FIG. 2. First, the cursor is set at the start point P1 and data is input, and then the cursor is set at the second point P2. And input data, side h1
Is drawn. Similarly, when the cursor is set at the final point Pn and data is input, a side h (h-1) is drawn, and when the end key is pressed, the side hn is drawn and the polygon is completed. Then, this polygon is registered with an identification number in case it is moved later.

Next, FIG. 4 is a flowchart for changing the already drawn polygonal shape. After designing (step S11), the "frame change" command (A3) is specified (step S12) The side of the polygon to be changed is specified (step S13). Then, the two sides in contact with the designated side are recognized (step S14), and when the cursor on the designated side is moved (step S15), the intersection with the preceding two sides is also moved (step S16). If there is no other side to move (step S17), register this new polygon (step S17).
18) Then finish.

The process of changing this polygon is shown in FIGS. 6 (A) and 6 (B).
First, when the side h11 to be changed is designated by the cursor, the two sides h12 and h13 in contact with this side h11 are recognized. Then, when the cursor is moved, the side h11 is moved in parallel, and as shown in FIG.
When moved to, sides 12 and 13 are accordingly extended (or shortened) until they intersect side h14, such as sides 15 and 16, respectively. Depending on the movement of the side designated by the cursor, for example, the quadrangle may become a triangle. At that time, even if the designated side is further moved at the time of becoming the triangle, the state of the triangle may be maintained. It is also possible to make the triangle smaller.

FIG. 5 is a flow chart for moving the already drawn polygon, and the "group move" command (16A) is specified during the design work (step S21) (step S2).
2) After that, when the polygon to be moved is designated (step S23), a search is performed in the horizontal / vertical direction from the designated point to confirm whether the designated point is inside the polygon (step S23).
S24) This is because if the specified point exists inside the polygon, it is possible to confirm that the specified point is inside the polygon because the sides of the polygon and the horizontal and vertical lines intersect at four points. is there. However, when two or more locations intersect in the same direction, only the first intersection is taught as one location. Then, the registration number of this polygon is searched (step S25), and the polygon itself is moved to an arbitrary location (step S25).
26) and finish.

The horizontal / vertical direction search when moving this polygon is shown in FIG. 7 and explained. First, assuming that the cursor is designated at an arbitrary point P21 inside the polygon, the horizontal and vertical directions will be centered around this point P21. If the search line is extended, it will intersect at points P25 and P23 on the sides h21 and h22 in the horizontal direction and at points P22 and P24 on the sides h21 and h23 in the vertical direction at a total of four places. Regarding this intersection, since only the first intersection in the same direction is recognized, if there are no specified points inside the polygon, there will not be four intersections,
It can be recognized that the polygon is specified no matter which position is specified inside the polygon. Next, when the registration number of this polygon is searched, the entire polygon can be moved as a whole.

In this way, polygons can be drawn, changed, and moved easily, but when registering polygons, it is possible to save memory capacity by storing only the coordinate values of each vertex, and to change the shape. In this case, only the changed state of the movement of the specified side is explained here, but this can be easily changed if only the intercept of the linear equation is used as the variable. However, if the gradient is also used as a variable, the shape can be freely changed.

When the complete positioning of the graphic is performed as described above, it is stored in the auxiliary storage device 32 according to the flowchart of FIG. 8 (step S52), or a hard copy is made on paper or the like by the output device 34 (step S51). ). Thus, the hard copy obtained from the output device 34 is used as the designated allocation paper 106 in printing. Further, a part of the information created here can be used as information for creating a printing mount, and the printing mount is created using a plotter based on this information. Further, when inputting a picture pattern, the processing information can also be used as the designated paper for allocation by treating the color original as the picture pattern.

(Effects of the Invention) As described above, according to the method of the present invention, the process of creating the designated designated paper in the trial and error process embodied from the plan is computerized from the conventional manual work, and is processed in real time at high speed and accurately by automation. The layout drawing time, the movement and the shape change can be done easily, so that the layout drawing time can be greatly shortened and the various print demands of today can be quickly achieved. It has a great advantage that it can cope.
