These functions will be described later. A computer program (application program) for realizing each of these functions is provided by being recorded on a portable recording medium (portable recording medium) such as a floppy disk or a CD-ROM, and transferred from the portable recording medium to the hard disk device 36. Is done. Alternatively, the program supply device may supply the computer system via a communication path. When the computer program is executed, it is transferred from the hard disk device 36 to the memory 14 and stored therein.
[0022]
In the present invention, the “recording medium” is not limited to the portable recording medium described above, but is an internal storage device in a computer such as various RAMs and ROMs, or an external storage fixed to a computer such as a hard disk. The device is also included. That is, the “recording medium” of the present invention is a computer-readable medium and includes various media on which a computer program is recorded.
[0023]
The mount line drawing data loading means 14d loads the mount line drawing data from the hard disk device 36 storing the mount line drawing data as the original image data of the present invention into the line drawing data memory 16.
[0024]
FIG. 2 is an explanatory diagram illustrating an example of an image indicated by the mount line drawing data. The mount line drawing data is obtained by reading a prepared mount using a scanner, and the mount includes a plurality of (eight in the illustrated example) created by a computer typesetting machine, a plotter, or the like. Line drawings are pasted by hand. An image obtained by reading such a mount is shown in the figure. As illustrated, the image IM of the mount line drawing data includes eight line drawing images IMG1 to IMG8.
[0025]
The eight line drawing images IMG1 to IMG8 preferably have the same size and the same cutout area. In FIG. 2, numbers “1” to “8” are entered in the line drawing images IMG1 to IMG8, but this indicates the direction of the line drawing images IMG1 to IMG8 for convenience, as illustrated. The eight line drawing images IMG1 to IMG8 are all in the same direction.
[0026]
FIG. 3 is an explanatory diagram illustrating an example of an image of one line drawing. A line drawing constitutes one page of a printed matter such as a magazine. As shown in the figure, each image IMG (one of IMG1 to IMG8) of the line drawing represents a registration mark such as a center registration mark Ta and a square registration mark Tb.
[0027]
Returning to FIG. 1, the mount line drawing data display means 14 e is for displaying the mount line drawing data on the CRT 34.
[0028]
FIG. 4 is a flowchart showing a main routine of line drawing processing shown in a computer program stored in the memory 14 and executed by the CPU 10.
[0029]
As shown in FIG. 4, when the processing is started, the CPU 10 first loads the board line drawing data from the hard disk device 36 into the line drawing data memory 16 by the board line drawing data loading unit 14d (step S100). Next, the CPU 10 displays the mount line drawing data in the line drawing data memory 16 on the CRT 34 by the mount line drawing data display means 14e (step S110). Subsequently, the CPU 10 determines whether or not a command for performing imposition processing has been activated by the user using the keyboard 30 or the mouse 32 (step S120).
[0030]
If it is determined in step S120 that the command has not been activated, the process exits to “END” and ends the process. On the other hand, if it is determined in step S120 that the command is activated, the process proceeds to step S130.
[0031]
In step S130, the CPU 10 executes a subroutine for performing line drawing cutout processing, and cuts out a line drawing portion from the image of the mount line drawing data displayed in step S110. In subsequent step S140, the CPU 10 executes a subroutine for performing imposition page data generation processing, and generates imposition page data by pasting the cut line drawing onto the page surface. The processes in steps S130 and S140 are performed for any one line drawing. In the subsequent step S150, it is determined whether or not the processing has been completed for all the line drawings. If determined, the process returns to step S130 to move the processing target to the subsequent line drawing. If it is determined in step S150 that the processing has been completed for all the line drawings, the process ends by exiting to “END”.
[0032]
FIG. 5 is a flowchart showing a line drawing cut-out process called by a subroutine from the main routine. The processing shifts from step S130 (FIG. 4) of the main routine to the subroutine of FIG. 5. First, the CPU 10 executes processing for displaying a dialog box for line drawing cutout processing on the CRT 34 (step S131). The line drawing cutout processing dialog box is used to input numerical values necessary for the execution of the cutout area designating unit 14a, and further constitutes a part of the imposition information setting unit 14b to provide information necessary for imposition It is also possible to input.
[0033]
FIG. 6 is an explanatory diagram showing a line drawing cutout processing dialog box. As illustrated, the line drawing cutout processing dialog box DB includes first to ninth data input fields d1 to d9 that prompt the user to input data. The first to ninth data input fields d1 to d9 are, in order, a cutout area size x, y coordinate value, a paste offset x, y coordinate value, a cursor display position offset x, y coordinate value, a job name, This is for inputting the cut file name and the page number of the page surface.
[0034]
The data input fields d1 and d2 of “Cutout area size” are used to specify the size of the rectangular frame of the cutout dedicated cursor displayed on the CRT 34 screen. FIG. 7 is an explanatory diagram showing a cut-out dedicated cursor. As shown in FIG. 7, the cut-out dedicated cursor CS is composed of a cross C1 and a rectangular frame C2, and the cut-out area of the line drawing can be determined by the rectangular frame C2. This cut-out dedicated cursor CS is displayed on the screen when the line drawing cut-out processing dialog box DB is displayed (step S132), and the cross C1 and the rectangular frame C2 move simultaneously using the mouse 32. The size S1 of the horizontal side of the rectangular frame C2 is changed according to the value input in the data input field d1 of “Cutout region size”, and the size S2 of the vertical side of the rectangular frame C2 is “Cutout region”. The size is changed according to the value input in the data input field d2.
[0035]
It should be noted that the size of the line drawing area that is most often used as an initial value is set in advance in the data input fields d1 and d2 for “cutout area size”. Once changed, the changed value is set when the line drawing cutout dialog box DB is activated next time.
[0036]
The “cursor display position offset” data input fields d5 and d6 designate the relative position of the rectangular frame C2 with respect to the cross C1 in the cut-out dedicated cursor CS. The reference point of the rectangular frame C2, here the rectangular frame C2 The distance between the lower left corner P1 and the intersection P0 of the cross C1 is determined by the value in the X direction and the value in the Y direction. That is, the size of S3 in the figure is changed according to the value input in the “cursor display position offset” data input field d5, and the size of S4 is input in the “cursor display position offset” data input field d6. It is changed by the value.
[0037]
Note that a value 0 is preset as an initial value in the data input fields d5 and d6 of “cursor display offset”. Once changed, the changed value is set when the line drawing cutout dialog box DB is activated next time.
[0038]
Next, how the user cuts out a line drawing using the cut-out dedicated cursor CS will be described. The user operates the mouse 32 while viewing the screen on which the line drawing to be cut out is displayed, here, the screen on which the mount image IM is displayed in step S110, and is dedicated to cutting out the line drawing area on the screen. Set the cursor CS. Specifically, since each of the line drawing images IMG included in the mount image IM displayed on the screen has dragonflies drawn thereon, as shown in FIG. 8, a specific dragonfly of the dragonflies is shown. Here, the intersection P0 of the cross C1 of the cut-out dedicated cursor CS is aligned with the left center registration mark Ta. As described above, the vertical and horizontal sizes of the rectangular frame C2 and the rectangular frame C2 for the cross C1 are determined according to the values of the data input fields d1 and d2 for the “cutout area size” and the data input fields d5 and d6 for the “cursor display position offset”. Therefore, by aligning the intersection point P0 of the cross C1 with the center registration mark Ta of the line drawing as described above, a rectangle is formed in an area of a predetermined size at a predetermined relative position from the center registration mark Ta in the line drawing. The frame C2 can be matched. Therefore, when the user inputs the values in the data input fields d1, d2, d5, and d6 corresponding to the type of the document to be a line drawing, the specific area ER in the line drawing (the area of effective data, the hatched portion in the figure). Can be selected in the rectangular frame C2. In this state, by clicking the button of the mouse 32, a specific area of the line drawing is designated by one point input.
[0039]
That is, in this embodiment, the area specifying means is configured to use the cut-out dedicated cursor CS. This area specifying means is characterized by the following points.
[0040]
An area designating device for designating an area of a predetermined shape on a display device screen,
Instructing the position on the screen, and a screen position indicating device that sends a specific signal in response to an operation from the operator,
A cursor that is movable in response to a command from the screen position indicating device, and a graphic part that is located at a relative position of the cursor and moves along with the movement of the cursor and has the same shape as the predetermined shape. Display control means for displaying on the screen;
Position information output means for outputting position information of the graphic part when receiving the specific signal from the screen position indicating device;
It is characterized by having.
[0041]
Data entry fields d3 and d4 of “Paste offset” in FIG. 6 are used to specify an offset value with respect to the origin of the page surface when imposing the cut line image on the page surface. That is, as shown in FIG. 9, when the line drawing 1M is pasted on the page surface PL, the origin PL0 of the page surface PL and the reference point of the line drawing 1M (here, the lower left as well as the reference point of the rectangular frame C2) The x-direction component Sx and the y-direction component Sy of the line segment connecting the corner portion lM0 are designated by the “Paste offset” data input fields d3 and d4.
[0042]
Note that a value 0 is set in advance in the data entry fields d3 and d4 for “Paste offset”. Once changed, the changed value is set when the next line drawing process cutout process dialog box DB is activated.
[0043]
In the “job name” data input field d7 in FIG. 6, a job name for specifying a set of page planes on which the cut line image is pasted is designated. A data input field d8 of “Cut out file name” is used to specify a file name for specifying the cut out line drawing. The “page number” data input field d9 is used to specify the page number of the page surface on which the cut line image is pasted. Here, the relationship between terms such as “line drawing”, “page surface”, and “job” will be described again. When considering page composition, one page of printed matter corresponds to one “line drawing”, and in the case of imposition of 8 pages, one image plane on which 8 pages are laid out is “page surface”. The job corresponds to the entire printed matter.
[0044]
Note that nothing is set as a default in the “job name” data input field d7, and when the next line image cutout processing dialog box DB is activated, the previously input characters are left as they are. In the “page number” data input field d9, a value 1 is preset as an initial value, and the value is incremented by 1 each time the next line image cutout processing dialog box DB is activated.
[0045]
Returning to FIG. 5, when the line drawing cutout dialog box DB and the cutout dedicated cursor CS are displayed in steps S131 and S132, the CPU 10 subsequently inputs the first to ninth data input in the line drawing cutout processing dialog box DB. A key input from the keyboard 30 by the user to the columns d1 to d9 is accepted (step S133), and a mouse input by the user using the cut-out dedicated cursor CS is accepted (step S134). Thereafter, a process is performed to determine which button of the “calculation” button BT1 or “cancel” button BT2 in the line drawing cutout process dialog box DB is clicked by the mouse 32 (step S135). If it is determined that the “Calculation” button BT1 is clicked, it is determined that both the key input from the line drawing cutout processing dialog box DB and the key input from the cutout dedicated cursor CS are correct, and the process proceeds to step S136. On the other hand, if it is determined in step S135 that the “cancel” button BT2 has been clicked, it is determined that these inputs are incorrect, and the process returns to step S133.
[0046]
In step S136, the CPU 10 performs the line drawing cutout process dialog box DB.FromVarious input data are read and stored in the memory 14. In step S137, the CPU 10 reads line drawing data of the line drawing area set by the cut-out dedicated cursor CS, that is, the line drawing area determined by the rectangular frame C2 of the cut-out exclusive cursor CS, as line drawing cut-out data, and stores it in the memory 14. Remember. Thereafter, the CPU 10 advances the process to “return” and exits from the “line image cut-out process”.
[0047]
FIG. 10 is a flowchart showing the imposition page data generation process in which a subroutine call is made from the main routine. When the processing shifts from step S140 (FIG. 4) of the main routine to the subroutine of FIG. 10, the CPU 10 firstly executes a job corresponding to the job name among the various data read in step S136 of the line drawing cutout processing (FIG. 5). Processing for selecting a directory is performed (step S141). Next, a process of selecting a page directory corresponding to the page number among the various data is performed (step S142).
[0048]
FIG. 11 is an explanatory diagram showing a directory structure of imposition page data. As shown in the figure, the imposition page data includes directories for each job such as “job A” and “job B”, and each job directory has an arbitrary number (in the figure, M1 and M2 are arbitrary). Directory of pages) is formed. In the directory of each page, a page layout file PF indicating the position where the line drawing data pasted on the page is pasted and a plurality of line drawing files LF indicating each line drawing data pasted on the page are included. Stored. In step S141, one job directory is specified. In step S142, one page directory in the job directory is specified.
[0049]
Returning to FIG. 10, the CPU 10 then determines whether line drawing data has already been pasted on the page indicated in the page directory based on whether data already exists in the page directory selected in step S <b> 142. (Step S143). Here, if it is determined that data exists, it is determined whether or not the data in the page directory can be deleted (step S144). This determination of deletion is made from the result of the key input by displaying a dialog box on the screen of the CRT 34 and prompting the user to input a key. If it is determined in step S144 that the data can be deleted, all data existing in the page directory is deleted (step S145). On the other hand, if it is determined in step S143 that no data exists, or if it is determined in step S144 that no data is to be deleted, no data is deleted.
[0050]
Thereafter, the CPU 10 performs processing for opening the page layout file in the page directory selected in step S142 (step S146). FIG. 12 is an explanatory diagram showing the data structure of the page layout file PF. As shown in the figure, the page layout file PF includes a page number field Fa for storing a page number, a page size field Fb for storing a page size, and n (n is an arbitrary number of 1 or more) pasted on the page. This is a structure including paste information fields Fc (1) to Fc (n) for storing paste information of line drawing data.
[0051]
The paste information fields Fc (1) to Fc (n) are a paste line image file name, a paste area type, a paste area size X component, a paste area size Y component, a paste offset X component, and a paste offset Y. Each of the component fields f1, f2, f3, f4, f5, and f6 is provided.
[0052]
After execution of step S146 in FIG. 10, the CPU 10 pastes the data of the cutout file name, cutout area size, and pasting offset of the various data read in step S136 into the page layout file PF opened in step S141. Write information field Fc (k) (where k is an arbitrary number from 1 to n) (step S147). Here, the field to be written is “Fc (k)” indicates that the writing position is the position that follows the past of the pasting information field Fc written so far.
[0053]
Specifically, the cut-out file name data read in step S136 is pasted into the pasted line drawing file name field f1, the cut-out area size X component data is pasted into the pasted area size X component field f3, and the cut-out area size Y component is displayed. The paste offset area size Y component data is pasted into the paste area size Y component field f4, the paste offset area size X component data is pasted into the paste offset X component field f5, and paste offset. Write in the Y component field f6.
[0054]
Subsequently, the CPU 10 writes a value 1 indicating that the paste area has a rectangular shape in the paste area type field f2 (step S148). Thereafter, the CPU 10 closes the opened page layout file PF (step S149).
[0055]
Thereafter, the CPU 10 performs a process of writing the line drawing cut-out data read in step S137 as a line drawing file in the job directory selected in step S141 (step S150). When the line drawing file is written in step S146, the process proceeds to “return” and exits from the “imposition page data generation process”.
[0056]
As described above, the imposition page data generation processing having such a configuration is executed for each line drawing, and when the processing for all line drawing is completed (step S150 in FIG. 4), the imposition page data shown in FIG. Built.
[0057]
Note that, using the imposition page data created in this way, a page product, in the example shown in FIG. FIG. 13 is an explanatory diagram showing the plate surface P of one printing sheet of 8 pages. In FIG. 13, numbers “1” to “8” are entered on each page, and this represents the orientation of the page for convenience. As shown in the drawing, the upper four of the eight pages are in an inverted state, and the lower four are in an upright state. In the subsequent process, the orientation of each page is set separately as imposition pattern data, and a printing paper plate is created from the imposition pattern data and the imposition page data described above. Note that the process of creating the printing plate is not particularly related to the present invention, and therefore the description thereof is omitted here.
[0058]
According to the line drawing processing apparatus of this embodiment, which has been described in detail above, imposition information such as page numbers and pasting information is set from a dialog box each time a line drawing is cut out using the cut-out dedicated cursor CS. Therefore, it is not necessary to select each line drawing again in the order of page numbers after all the line drawings have been cut out as in the prior art. Therefore, imposition of a plurality of line drawings can be performed with good workability. In addition, since the imposition information is keyed in from the dialog box, it is not necessary to perform the work of moving the line drawing data to the holder as in the prior art, so that the operability is more excellent.
[0059]
In addition, this invention is not restricted to said Example, In the range which does not deviate from the summary, it is possible to implement in various aspects.
[0060]
For example, in the above-described embodiment, the line drawing is cut out using a dedicated cursor, but instead, a normal cursor that indicates only one point is used to indicate two diagonal positions of the rectangle. It is good also as a structure which defines a cutting-out area | region by this. At this time, the imposition information of “pasting offset”, “job name”, “cut file name”, and “page number of the page surface” described above is data using a dialog box as in the configuration of the above-described embodiment. It should be possible to input.
