DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described by way of an example of a form editor that edits form data that is an image overlaid on print data.
[0014]
[First Embodiment]
FIG. 1 is a block diagram of a computer having a form creation function in this embodiment. This form creation function operates when the CPU 10 executes a basic input / output (I / O) program, an operating system (OS), and a form creation program. The basic I / O program is written in the ROM 11, and the OS is written in the hard disk (HD) 15. When the computer is turned on, the OS is read from the HD 15 into the RAM 12 by the IPL (Initial Program Loading) function in the basic I / O program, and the operation of the OS is started. The procedure of the form creation program will be described later. The form creation program and related data are recorded in the FD 14, and the configuration of the recorded contents is shown in FIG.
[0015]
The form editing program and related data recorded in the FD 14 can be loaded into the computer system through the FD drive 13. When the FD 14 is set in the FD drive 13, the form creation program and related data are read from the FD 14 under the control of the OS and the basic I / O program, and loaded into the RAM 12 to be operable. FIG. 16 shows the configuration of the layer form editing program in the storage medium.
[0016]
FIG. 2 shows a memory map in a state where the form editing program is loaded into the RAM 12 and can be executed.
[0017]
In this embodiment, the form editing program and related data are directly loaded into the RAM 12 from the FD 14 and executed. However, in addition to this, the form editing program and related data are temporarily stored (installed) in the HD 15 from the FD 14. The form may be loaded from the HD 15 to the RAM 12 when the form editing program is operated. The medium for recording the form editing program may be a CD-ROM, an IC memory card, or the like in addition to the FD.
[0018]
Form data created by the form editing program is stored in the HD 15, and is overlaid with print data by another application program that realizes overlay printing, and is output from the printer 18.
[0019]
<Overview of form overlay processing>
Before describing the form editing function according to the present invention, an overview of the entire form overlay processing will be described. FIG. 3 shows the flow of processing for the entire overlay printing including the form creation program. The form or composite form created by the form editing program (hereinafter also referred to as “form editor”) 311 is stored in the form data storage unit 312 prepared in the HD 15 or the like. The form is image data to be overlaid, and includes graphics, characters, or dot images. The composite form is a form configured in units of pages, and each page is configured by superimposing forms that are parts. You can also define special pages such as double-sided and copy. Each form (including a composite form) includes form data 312a representing the form itself and field attribute data 312b representing the position, character type, and the like of the print data combined with the form. Hereinafter, the composite form data may be referred to as FCX data, and the form data that is not combined and is the minimum unit may be referred to as FCP data. Hereinafter, the FCX data may be simply referred to as image data, and the FCP data may be referred to as component image data.
[0020]
These form data are converted into form print data 316a in a format interpretable by the printer 32 by a predetermined runtime library 315, and stored in a printer data storage unit 316 secured in the HD 15.
[0021]
On the other hand, print data for form overlay printing is generated by an appropriate business file 313 and stored in the text data storage unit 314. The data need only be in a format that can distinguish each field to be overlaid. For example, a commonly used format called CSV format can be used. This print data is also converted into print print data 316 b in a format that can be interpreted by the printer 32 by the runtime library 315 and stored in the print data storage unit 316.
[0022]
The form print data and print print data created in this way are output to the printer 21 by the operating system 317 and printer driver 318, where they are combined and printed.
[0023]
FIG. 4 shows an example of each of form data and print data, and an example of a sequence of print commands passed to the printer 32. FIG. 4C shows an example of a command sequence. First, there is a form data registration start command 411 following a command sequence for starting a print job, followed by form data 412 as shown in FIG. In this example, the form is one page, but it may be a composite form. Thereafter, there is a form data registration end command 413, followed by print data 415 and 416 sandwiched between an overlay print start command 414 and an overlay print end command 417. An example of print data is shown in FIG. In the example of FIG. 4C, since the print print data is for two pages, the form print data is also a composite form for two pages.
[0024]
When such a command sequence is sent to the printer 32, the printer temporarily stores the form print data in the form cache 321, rasterizes the print data and the form data, and combines them on the page buffer 323. This data is printed out from the print engine 324, and a target printed matter is obtained.
[0025]
<Function of form editor>
The above is an overview of form overlay printing. Here, the form creation program (form editor) of this embodiment will be described with reference to the drawings.
[0026]
FIG. 5 is an example of a display screen when the user designates creation of a new form after the form editor is activated. Inside the window 501, a menu line is displayed at the top thereof, and a window 502 for selecting what an object to be newly created is displayed below the menu row. Here, three types of field data, form, and composite data can be selected. When the field data field 403 is selected, the procedure for editing the field attribute file 312b in FIG. When the form field 404 is selected, a procedure for editing one-page component form data is entered. The component form data alone can be form data for one page.
[0027]
When the composite form field 405 is designated, the screen moves to a composite form data editing screen shown in FIG. On the composite form data editing screen, the structure of the composite form data to be edited is displayed in the tree display field 602. On this screen, you can use a pointing device to move, delete, or insert a specified object on the screen, or to change the name of an object from the keyboard. Can do. When editing an existing composite form, the form editor can be called by specifying the name of the composite form data file. Thereby, the composite form data is read from the form data storage unit 312 and a tree reflecting the structure is displayed. The composite form display field (or preview field) 601 displays an image of the selected page in the composite form. Details of this will be described later.
[0028]
FIG. 7 shows an example of a tree (tree view) to be displayed. The root of each tree represents the entire composite form, and its lower node 802 represents a page constituting the composite form. A page represents one page to be printed, and there are several types depending on the configuration of the page itself. For example, pages 802a, 802b, and 802c that simply include a component form are composite forms in which the component forms underneath are stacked in order from the top. For example, the page 802a is configured by overlapping the component 02 on the component 01. In addition, there is a double-sided node 802c indicating that the page under it is printed on both sides. In addition, although not shown, there is a copy node indicating that a specified number of copies are repeatedly output. In the case of a double-sided page, there are further pages underneath, and in the tree view display, the upper page means the front side and the lower page means the back side.
[0029]
A node 809 that links pages together as a subtree indicates that the subtree is displayed, and “+” indicates that the subtree is not displayed. Hereinafter, a node indicating an object may be referred to as an item. Each node is displayed as an image object called an icon, and a line connecting the icons indicates that the node on the right side of the line is subordinate to the node on the left side.
[0030]
Printing is performed in units of pages, and each page includes at least one component form. In the case of a page having a plurality of component forms, a superposition of the component forms is printed as one page. The order of the part forms under the page in the tree view represents the order of overlapping when the part forms are overlapped, and the parts are stacked in order from the top in the tree view display. In other words, when the page is displayed, the component form at the bottom of the tree view is at the top.
[0031]
FIG. 8A shows an exemplary structure of a composite form data file representing a composite form. In FIG. 8, the composite form data “Test.fcx” is stored in a directory “c: ¥ Program Files ¥ Fcpro ¥ FORMWORK”. The content indicates that the page number field 101 is 3, and includes 3 print pages in total. The page name 102 is the name of the defined print page and is “Nenkin01”. The number of repetitions represents the number of times that the page is repeated. The page type field 104 is a standard page and indicates a normal page that is not double-sided or copied. The file name field is displayed with a full path, and the file name “Nenkin01.fcp” is written at the end. That is, it can be seen that this print page includes only “Nenkin01.fcp” as the component form.
[0032]
The next print page Nenkin02 includes three part forms “Nenkin02.fcp”, “Nenkin03.fcp”, and “Nenkin04.fcp”.
[0033]
FIG. 8B is a diagram in which the composite form data in FIG. The tree view accurately expresses the contents of the composite form data, and expresses the structure in a format that is easy to understand intuitively.
[0034]
<Edit composite form>
Next, a part of the processing procedure of the form editing program in this embodiment is shown in FIGS. The procedure of FIG. 9 is a procedure that is executed when the operator makes some input when the editing program is activated and the composite form is read.
[0035]
First, it is determined whether the operation input by the operator is selection of a component form (step S901). The selection of the component form is executed when the operator selects a desired component form icon using the keyboard 16 or a pointing device (not shown) on the tree view of FIG. If it is determined that the part form is selected, the selection status of the part form is set (step S902). If it is determined that the component form is not selected, it is determined whether the instruction is a display instruction on the component form (step S903). The display instruction in the component form is performed by selecting a component form icon or a page icon on the tree view and inputting a display command or selecting display from a menu.
[0036]
If it is a display instruction, it is determined whether there is a selected form, that is, a component form in which the selection status is set (step S904). If there is, the editing status of the selected part form data is set (step S905), and the page to which the part form belongs is displayed (step S906). At this time, the component forms other than the component form in the selectable state are displayed in gray, and the fact that they are not in the editable state is displayed in an identifiable manner for the operator. If it is determined that the part form is not used, the page to which the part form belongs is displayed on the preview screen 600 as it is.
[0037]
On the other hand, if the input is not a display instruction, it is determined whether it is an editing operation (step S907). If the input is an editing operation, editing processing corresponding to the input is performed on the component form data and composite form data for which the editing status is set (step S907). Step S908). At this time, it is checked whether the input is in accordance with a predetermined sequence of editing operations. If it is not any input, processing corresponding to the input is executed (step S909).
[0038]
FIG. 10 shows the procedure of page display processing in step S906.
[0039]
First, in the selected page or the page including the selected part form, an attempt is made to obtain the first part form (step S201), and it is determined whether the part form exists (step S202). The part form image is displayed (step S203). Then, the next part form is obtained (step S204), the process returns to step S202, and page display processing is performed until there is no part form. Here, the order of the component forms may be the order in which the component form files included in the page are arranged, as shown in FIG.
[0040]
FIG. 11 shows the component form display process in step S203. First, the status of the component form to be displayed is set in the variable LS (step S301). The status of the part form includes an edit status and a display status, and each takes a value of ON or OFF.
[0041]
Next, it is determined whether or not the display of LS is ON (step S202). If the display is ON, the first graphic belonging to the layer is obtained (step S303), it is determined whether there is a graphic (step S304), and if there is no graphic, the process is exited. If there is a figure, the figure is displayed (step S30S). When the graphic display processing is completed, the next graphic belonging to the same component form is obtained (step S306), the process returns to step S304, and graphic display processing is performed until there is no graphic belonging to the same component form.
[0042]
FIG. 12 shows the graphic display process of step S305. First, the type of figure is determined (step S401). If it is a vector figure, vector figure display processing is performed (step S402). If it is a character, character display processing is performed (step S403). If it is an image, image display processing is performed (step S404). , Exit the process.
[0043]
FIG. 13 shows the vector graphic display process of step S402. First, the line color and the face color are obtained and set to the variables LC and FC, respectively (step S501), it is determined whether the status LS of the part form is edit ON (step S502), and if the edit status is OFF, LC, FC Each brightness is increased by a certain value (step S503). When the brightness value of the color is increased, it can be made light while maintaining the same hue. Next, a vector figure is drawn using LC and FC (step S504).
[0044]
In this way, the vector graphic belonging to the component form with the display status OFF is not displayed, the vector graphic belonging to the component form with the display status ON and the edit status ON is displayed normally, and the component with the display status ON and the edit status OFF is displayed. Vector graphics belonging to the form are displayed in a lighter color than usual.
[0045]
Similarly, in the character display process of step S403 shown in FIG. 14, first, the character color is obtained and set in the variable CC (step S601), and it is determined whether the status LS of the part form is the edit status ON (step S602). If the editing status is OFF, the brightness of CC is increased by a certain value (step S603). Next, a character is drawn using CC (step S604).
[0046]
Similarly, the image display process in step S404 shown in FIG. 15 first obtains the first pixel (step S701), determines whether there is a pixel (step S702), and exits the process if there is no pixel. If there is a pixel, it is determined whether the editing status is LS (step S703). If the editing status is OFF, the brightness of the pixel is increased by a certain value (step S704). Next, a pixel dot is drawn (step S70S), the next pixel is obtained (step S706), the process returns to step S702, and pixel drawing processing is performed until there are no more pixels.
[0047]
As described above, when a page or part form is selected and displayed, if the part form is selected, the part form is displayed in the normal color as being subject to editing, and the selected part is displayed. An unselected part form included in the same page as the form can be displayed in a thin color. If no part form is selected, all the part forms included in the designated page can be displayed as usual.
[0048]
FIG. 20 is a diagram of a display example when a component form is selected. In this case, the part 1 has a round figure at the top, the part 2 has a rectangle in the middle, and the part 3 has a triangle at the bottom. When a part 2021 is selected in the tree view, the part form is displayed as usual in an image display area 201 as an image 2011, and the others are displayed lightly as images 2010 and 2012. In this way, when editing a component form, not only the component form to be edited but also all the component forms included in the selected page are displayed. Further, in order to display the selected component form in an identifiable manner, the page configuration can be displayed in the tree view, and the synthesized page can be displayed. Further, since the selected component form can be identified while performing such display, the component form can be edited on the synthesized page image.
[0049]
In addition, when a component form is displayed as shown in FIG. 20, by selecting an icon of another component form in the tree view 202, the newly selected component form is set as an edit target, and the component that has not been selected. The form can be displayed again in the image display field 201 so as not to be edited. For this purpose, it is determined whether the selected component form is currently displayed between steps S901 and S902 in FIG. 9, and if it is displayed, the selection status of the component form is set, and then step S904 is performed. Branch to If not, the process branches to step S902 in FIG. When a certain part form is selected, selection of other part forms is cancelled.
[0050]
In this way, the display state of the selected page can be changed by operating the tree view.
[0051]
If no part form is selected, page display is performed with the variable EF cleared, and therefore, the parts are displayed in the order of overlapping parts files.
[0052]
[Modification of First Embodiment]
In the above-described embodiment, the display of the part form graphic being edited is a normal display, and the non-edited part form graphic is displayed in a lighter color than usual. Here, the vector graphic display processing step S402 and the character display processing step S403 in FIG. 12 are changed to the processes shown in the flowcharts of FIGS. 17 and 18, respectively. In steps S1003 and S1103, the vector graphic / Characters can be displayed in a specific line type / face type (color is an actual color) determined in advance.
[0053]
If the image display processing step S404 of FIG. 12 is changed to the processing of the flowchart shown in FIG. 19, the display of the image of the part form that is not being edited is the same size as the image and is determined in advance by setting. A specific line type, line color, surface type, or surface color can be displayed as a rectangle.
[0054]
In this way, an image that is not an editing target shows its area and does not display details, so that even if the image is complex, display processing does not take time.
[0055]
Also, in this embodiment, each component form is a single file, and there is separate composite form data that sets what the file of each component form is. In contrast, even data in which images such as all component forms are present in one file can be displayed in the same manner as in this embodiment.
[0056]
[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. In the present embodiment, the processing for three steps of steps S904 to S906 in FIG. 9 is replaced with FIG.
[0057]
When the user selects an item in the tree view and instructs to display it, first, the type of the item is determined (step S1401). If the type is a part file, a part selection display is performed (step S1402). If there is, page selection display is performed (step S1403).
[0058]
The component selection process in step S1402 is shown in FIG. First, the name of the selected part form item is set in the variable EF for storing the edit file name (step S1501). The name of this item is the same as the name of the corresponding file. Next, a page that is a parent item of the selected component form item is obtained (step S1502), and page display processing of the obtained parent page is performed (step S1503). The variable EF is referred to during various editing processes on the preview screen (corresponding to the display field 600 in FIG. 6), and is controlled so that contents other than those included in the part file having the name of the variable EF cannot be edited.
[0059]
The page display process in step S1503 is shown in FIG. In FIG. 23, first, an attempt is made to obtain a part file which is the lowest layer among the part files constituting the page to be displayed (step S1601), and it is determined whether it exists (step S1602). Then, it is determined whether the name of the obtained component file is the same as the content of the variable EF (step S1603). If they are not the same, the graphic contained in the component file is displayed on the preview screen (step S1604), and if they are the same, they are not displayed.
[0060]
Then, an attempt is made to obtain the next part file included in the same page (step S1605), and the process returns to step S1602 and is repeated until there is no part file. If there is no part file, it is determined whether the file name is set in the variable EF (step S1606). If it is set, the file having the name stored in the variable EF is displayed at the top of the preview screen (step S1607). ). Note that the display of the part file graphic in step S1604 and step S1607 is executed in the same procedure as in FIG. 12 in the first embodiment. By doing so, the part file being edited is displayed at the top, so that it is easy to edit without being hidden by the figure of another part file.
[0061]
FIG. 25 is a diagram illustrating an example of a displayed component form. In the tree view 252, “Part 2” on the “Cover” page is selected, and the part form “Part 1”, “Part 2”, and “Part 3” included in the “Cover” page are displayed on the preview screen 252. The Among these, the selected “component 2” is displayed at the top. In FIG. 25, part 1 includes a circle 2510, part 2 includes a rectangle 2511, and part 3 includes a triangle 2512. In this example, since the component 2 is selected, the rectangle 2511 that should be hidden by the triangle 2512 of the component 3 is displayed at the top in the order of the component form.
[0062]
FIG. 24 shows the page selection process in step S1403 of FIG. First, the variable EF is cleared (step S1701), the selected page is obtained (step S1702), and page display processing of the obtained page is performed (step S1703). The page display process in step S1703 is the process shown in FIG. Thereby, when a part form is not selected but a page is selected and display is instructed, the part forms included in the page are sequentially displayed. As this order, for example, as shown in FIG. 8A, the order of the component form files included in the page defined in the composite form data may be used.
[0063]
As described above, when a component form is selected, the selected component form is displayed on the other component form in order to display the entire page so that the component form is overlaid. The part form can be edited while viewing the image of the entire page.
[0064]
[Third Embodiment]
In the second embodiment, the case where a document is composed of component files and page items has been described. However, it is also conceivable that a double-sided page can be set as an item constituting a document.
[0065]
The double-sided page is composed of two pages. For example, the tree view of FIG. 7 includes pages named “page 01”, “page 02”, “page 00”, “double-sided” and double-sided pages in order from the top. ”And“ Page 02 ”. In this case, the process of FIG. 26 is performed instead of the flowchart of FIG. 21, and the display for the double-sided page is performed.
[0066]
FIG. 26 shows that when a double-sided icon is selected and instructed to be displayed on the tree view, including item selection display and page selection display as well as double-sided selection display as the item type, step S2104 is executed. .
[0067]
FIG. 27 shows details of step S2104. First, the variable EF is cleared (step S2201), the preview screen area is divided into two parts for the front side and the back side (step S2202), and the front page constituting the selected double-sided page item is obtained (step S2203). . The page display process of the page obtained here is performed according to the procedure of FIG. 23, and the front page is displayed in one of the divided preview screen areas (step S2204). However, here, the play view screen is divided side by side, and the front page is displayed on the left side of the divided preview screen area.
[0068]
Next, the back page is obtained (step S2205), and page display processing of the obtained page is performed (step S1206). Here, the back page is displayed in the area on the side where the front page is not displayed. Steps S2204 and S2206 are the processing of FIG.
[0069]
In this way, when the double-sided page item is selected, the preview screen can be divided into two as shown in FIG. Similarly to the case where the page item is selected, the page display is performed in a state where the variable EF is cleared. For this reason, the front side and the back side of the double-sided item can be viewed simultaneously.
[0070]
In addition, when a part form for a page that constitutes both sides is selected, the part form is displayed at the top of the part form that constitutes a page. It becomes easy to check the contents.
[0071]
【The invention's effect】
As described above, according to the present invention, the component image can be displayed so that the entire image can be easily grasped, or the displayed component image can be edited. As a result, the component image can be observed or edited while viewing the positional relationship between figures including different component images. In addition, the front side image and the back side image of the double-sided page can be displayed at a time.
