Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus for creating and editing a document having a large paper size, which is composed of various types of elements such as characters, figures, tables, graphs and images.

[0002]

2. Description of the Related Art In recent years, a document processing apparatus has a storage device and a storage area having a large capacity as the hardware becomes cheaper and the operability and processability are improved and improved. There is an increasing number of devices that simultaneously edit and process various data such as character data, graphic data, table data, graph data, and image data on a single display device in a large editing area. For document information with such a large area, edit operations can be performed simultaneously in areas that are far apart from each other, such as reducing the display, scrolling, changing the displayed area by switching pages, or displaying multiple identical documents at the same time. It was common to do

[0003]

However, when editing a large-sized document as described above with the conventional document processing apparatus, the operator scrolls the screen to display the document in a limited display area. The method of displaying the document, reducing the size of the document, or displaying a plurality of the same document was used. Therefore, when you want to edit areas that are separated from each other in the same document alternately, you can move the display area, operate across multiple display devices, or perform detailed operations on a reduced and small document. It is necessary to perform the operations, the number of operations of the mouse and the like is increased, and moreover, delicate editing operations are required, which has a drawback that the operability and the reliability of the document information are significantly deteriorated.

[0004]

In order to solve the above problems, the present invention provides means for setting an arbitrary number of areas as non-display areas which are not displayed on a display device when a document is displayed on the display device. A display function is provided to continuously display only the remaining area excluding the same area according to the setting and setting, and the same editing operation can be performed simultaneously on all displayed areas. Is.

[0005]

According to the present invention, by providing the above-mentioned means and using the function of setting the non-display area in the document being edited, the reduction display function or the function of simultaneously displaying a plurality of the same documents at the same time is used until once. Thus, it becomes possible to display, on a single display device, an arbitrary size of a distant area of a large paper size document that could not be displayed on the single display device.
Therefore, it is possible to operate the plurality of distant areas at the same time without distinguishing them on one display device while grasping the entire document in a size that is easy for the operator to see and operate. In addition, since the same document is not displayed multiple times, it is possible to perform the same operation without distinguishing each area, and a conflict occurs between the displayed document that has been edited and the displayed document that has not been edited. Of course, after the edited document is saved, the document that is not edited by mistake is not overwritten, and the document information can be edited more freely and quickly, and the maintainability is improved.

(Hereinafter, referred to as CPU), 12 is an external storage device that stores various programs and data, 13 is a main storage device (main memory) that stores various programs and data, and 14 is various input devices such as a keyboard and a mouse. An input device management unit that manages, a keyboard that inputs characters and the like, a mouse that inputs data such as coordinates, and a random access memory for display (17, V
RAM), 18 is a display control device for editing / controlling information in VRAM, 19 is a cathode ray tube (hereinafter referred to as CRT) display device for displaying information edited and controlled by the display control device 18, and 20 is a CPU and others. Is a bus for exchanging information with other devices. The operation of the embodiment configured as above will be described. FIG. 2 is a flowchart showing the flow of processing of the non-display area setting operation. First, a document editing operation event by the operator that occurs during the document editing process is extracted (S1). Next, the type of the extracted event is determined (S2), and if the result of the determination is that the event type is a non-display area setting request, the process proceeds to event extraction (S3). ), Otherwise proceeds to edit processing (S11). Next, the event retrieval (S
When the process proceeds to 3), the process proceeds to event determination (S4), and it is determined whether the extracted event is the end of the non-display area setting. If the event is a request to finish setting the hidden area, redisplay the document (S
Proceed to 9). If not, the type of the event extracted (S3) is determined (S5). If the event type is the first mouse button click (start point setting operation of non-display area), go to the start point setting (S6) .If the event type is the second mouse button click (end point setting operation of non-display area), end point. Proceed to setting (S7), and if dragging with the mouse, proceed to area setting (S8). In the start point setting (S6), the clicked coordinates of the mouse button are stored as the start point of the non-display area, and the process proceeds to S3. Further, in the end point setting (S7), the coordinates clicked by the mouse button are stored as the end point of the non-display area, and a line segment indicating the non-display area is displayed between the start point setting (S6) and S3. move on. Furthermore, in the area setting (S8), according to the movement amount and movement direction of the mouse,
The line segment is moved / transformed to determine the display area, and the process proceeds to S3.
In the case of the document redisplay (S9), the document is redisplayed on the display device according to the non-display area information set in the area setting (S8) or released in the area release (S10), and the process returns to S1. Area release (S10)
Then, all the non-display area information that is currently set is canceled and the process proceeds to document redisplay (S9). In the editing process (S10), enlargement, reduction, transformation,
After making edits suitable for the edit processing mode at that time, such as rotation and movement, and creating figures, tables, graphs, and documents according to the edit processing mode at that time, the process returns to S1. 3 to 11 show screens in each case in one embodiment of the present invention. FIG. 3 shows screen display information before setting a non-display area, and FIGS. 4 and 5 show setting operation of the non-display area. 6 shows the screen display information after the non-display area is set, and the change of the document information by the graphic drawing during the non-display area setting and the graphic drawing after the non-display area setting is released in FIGS. Note that, here, "region-independent" means that when the non-display area setting is cancelled, figures drawn across each area are not connected. It also means that data is supplemented and automatically drawn. In addition, an absolute figure means that a figure drawn while setting the non-display area has a similar shape after the non-display area setting is released. It means that the shape such as changes.

[0007]

As is apparent from the above embodiment, the present invention uses a function of setting a non-display area in a document being edited in a document having a large paper size that cannot be displayed on the display device at one time. This allows areas of the same document that are separated from each other to be displayed on one display device at a time in an arbitrary size. Therefore, it is possible to simultaneously operate a plurality of distant areas on one display device while grasping the entire document in a size that is easy for the operator to see and operate. Furthermore, by enabling editing to be performed over a plurality of areas displayed simultaneously on one display device, more editing operation functions can be realized. Also,
Since the same document is not displayed multiple times, the same operation can be performed without distinguishing each area, and a conflict may occur between the displayed document that was edited and the displayed document that was not edited. In addition, after the edited document is saved, the document not edited by mistake is not overwritten, and the maintainability of the document information is improved. Therefore, by using this function, it becomes possible to edit a large document more freely and more quickly, and also it is possible to improve maintainability.
