Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document data editing device, and particularly to editing a document in which vertical and horizontal characters are mixed on one page.

[Conventional technology]

With the recent advances in word processors, document data editing devices that electronically perform plate making have been developed. Such a document data editing device inputs document data created with a commercially available word processor, performs various editing operations, and prints a manuscript for plate making or directly prints onto a plate material. There are two types of editing methods: one in which a dot image with a lower dot density than the actual printed image is displayed, and the other in which the actual printed document dot image is displayed also in editing. In the former, a print image is created from word processor document data using coarse characters built into the system, managed by code, and edited. Creates an actual dot image during final output. In the latter case, an actual dot image is first created based on word processor document data, and editing is also performed on the dot image.

Here, in the former case, a general scrollable display is often used. If a scrollable display is used, there are constraints on the vertical and horizontal length of the display screen (vertical, horizontal), the vertical and horizontal length of one page of a document, and the writing direction of text in the document (vertical, horizontal). There isn't.

For example, when editing a document with characters written horizontally on horizontally long paper on a vertically long display, you can rotate the document 90 degrees and scroll the screen horizontally to edit the document, albeit partially. Can display the entire data.

In the latter case, a so-called bitmap type display with high resolution is often used as the display, but in many cases, the screen of the bitmap type display cannot be scrolled. In order to display the document in the above example on a vertically elongated display where the screen cannot be scrolled, it was necessary to specify a portion of the document and rotate and display each portion. Here, when specifying, the range must be determined by considering whether the area after rotation will fit within the display screen, and this specifying work is quite troublesome.

On the other hand, instead of scrolling the screen, there were devices that could rotate the display itself by 90 degrees. However, the rotation mechanism of the display itself has the disadvantage that the device itself is large and tends to be unstable.

[Problem that the invention seeks to solve]

This invention was made to deal with the above-mentioned circumstances,
The purpose is to provide a document data editing device that can display a document in which vertically written characters and horizontally written characters are mixed on a display that does not have a scrolling function in an orientation that is easy for the user to view.

[Means for solving problems]

The document data editing device according to the present invention reads document data in which vertically written characters and horizontally written characters are mixed, created by another device, and creates a print image using the tn document screen control unit 2.
2, and a display 5 that does not have a scrolling function and displays the print image read by the fair copy screen control unit 22.
2, detecting an area where the writing direction of characters is different from the basic direction while creating a print image by the fair copy screen control unit 22;

and.

[Effect]

According to the document data editing device according to the present invention, when the fair copy screen control unit 22 develops a print image in the image memory 40, a rectangular area whose format is different from the basic format is automatically registered in the document format management table 5B. Therefore, the user can specify a rectangular area that includes that point by simply specifying a point within the rectangular area with the mouse, without specifying each of the four corners of the rectangular area, and the user can rotate the specified rectangular area and display the characters. By displaying the images in an arrangement that is easy for the user to see, it is possible to easily check the printed image.

The character image editing control unit 20 has a data buffer 36°38
is connected. Data buffer! , 38 store data before and after rotation, respectively.

An image memory 40 for storing print images of documents is connected to the la document/image side control section 22 . document data storage section 42;
A character font data storage section 44 is also connected to the fair copy screen control section 22. The document data storage unit 42 stores document data (code data) created by another device (word processor) in the form of a storage medium such as a floppy disk. Here, it is assumed that a one-page document contains both vertically written characters and horizontally written characters. A display memory 46 and a frame memory 48 for displaying a printed image of a document are connected to the display screen control unit 24. ii! ii Image memory 401 display memory 4B, frame memory 48, data buffer 38.
It is also connected to 3a. The frame memory 48 stores a portion of the print image in the display memory 4G, and
The thinned out print image is stored via the thinning processing circuit 50. The data in the display memory 46 is displayed on the vertical display 5.
Displayed as 2.

An image processing processor 54 is connected to the character image editing control section 20 and the rotation control section 26 for rotating, enlarging, reducing, etc. the image. A data buffer 38.38 is connected to the image processing processor 54. A document format management table 56 is connected between the fair copy screen control section 22 and the rotation control section 26.

Sentence! An example of the F-format management table 5B is shown in FIG.

Table 56 shows a rectangular area in which the writing direction of characters in one page of a document in which vertical writing and horizontal writing are mixed is different from the basic direction (the horizontal writing part if vertical writing is the default; It stores the coordinates of the two corners (upper left, lower right) of the vertically written portion, and includes an entry number register B2 indicating the number of storage areas, and an upper left coordinate register 64-1 in the frame memory for each area. It includes a lower right coordinate register 66-1, an upper left coordinate register 68-1 in the image memory, and a lower right coordinate register 70-1 (i-1 to n). here,
The coordinate is X.

It is given in Y coordinate.

The operation of this embodiment will be explained.

1 of the document data stored in the document data storage section 42
The page is read. The fair copy screen control section 22 reads out the dot image of the corresponding character from the character font data storage section 44 based on the character code and function code (data related to the format of the character, indicating vertical writing, horizontal writing, etc.) therein. A print image for one page is created in the image memory 40. Here, the document has the same aspect ratio as the screen,
Suppose that most of the characters are written horizontally on horizontally long paper. In other words, horizontal writing is the basic format in this case.

Figure 3 shows frame memory 48 and data buffer 36.3.
FIG. The data in this frame memory 48 is displayed on a portrait display 52.

That is, the horizontally long document data is rotated 90 degrees clockwise, written into the frame memory 48, and displayed on the display 52 as a vertically long document. As previously mentioned,
Since horizontal writing is set as the basic format, an area such as the rectangular area 7B that includes "Kakiku" is a range of a format different from the basic format.

In the process of creating this print image, the fair copy screen control unit 22 detects a rectangular area with a format different from this basic format based on the function data, and selects the two corners (top left,
(lower right) coordinates are registered in the document format management table 52.

Here, the coordinate values (address) of the image memory 4° are also registered as the coordinate values of the frame memory. The fair copy screen control unit 22 updates the data in the total number of entries register 62 of the document format management table 56 every time this rectangular area is registered.

Sentence! The F format management table 58 registers all rectangular areas in formats different from the basic format.

While displaying or editing a print image, the portrait display 52
The parts of the screen that are not vertically written (for example, "
If the user wishes to display the contents of the rectangular area 76) including "Drawing" in a format that is easy for the user to view, that is, in vertical writing on the screen, an instruction signal for partial rotation of the screen is input from the keyboard 12 to the main control unit 1o, and the rotation control unit 26 is operated.

When the mouse I4 is operated to move the mouse cursor into the rectangular area 7B whose contents are to be confirmed by rotating it and set the cursor, the human control unit 18 reads the coordinate position of the mouse cursor and stores it in the cursor address register 32. Set to .

The rotation control unit 2G searches the document format management table 56 and detects whether the coordinate position of the cursor address register 32 corresponds to any of the rectangular areas registered in the document format management table 56. When a rectangular area of the frame memory 48 including the coordinate position of the cursor address register 32 is detected, the data of the rectangular area is cut out from the frame memory 48 and transferred to the data buffer 36. After this, the data in the frame memory 48 is erased. In this way, since the rotation process is performed using thinned-out data, less data is required than when performing the rotation process using original image data, and the rotation process can be performed at high speed.

The rotation control unit 26 operates the image processing processor 54 to perform counterclockwise rotation processing on the image data in the data buffer 3G, and writes the processing result to the data buffer 38.

The left-rotated rectangular area is transferred to the frame memory 48 and then to the portrait display 52, where only the area 76 including "Kakiku" is displayed, and "Kakiku" is displayed in vertical writing. This allows the user to easily check the printed image without tilting his/her head. Furthermore, while the print image is being expanded from the document data storage unit 42 to the image memory 40, areas whose format differs from the basic format are automatically registered in the document format management table 56, so the user can select each rectangular area one by one. Even without specifying the four corners, by simply specifying one point within the rectangular area with the mouse, the rectangular area including that one point can be rotated and displayed, making it easy to operate.

The above explanation was an example in which the image is partially rotated and displayed, but a case in which the entire horizontally long paper is rotated to confirm the contents will be described next. In this case, keyboard 12
Enter instructions for total rotation from . The rotation control unit 2B transfers the entire data in the frame memory 48 onto the data buffer 36, performs counterclockwise rotation processing as in the above case, and transfers the result to the data buffer 38.

At this time, the rotation control unit 26 determines whether the vertical and horizontal sizes of the rotated area 78 fit within the vertical and horizontal sizes of the frame memory 48, and if they exceed the area of the frame memory 48, the data buffer 38 is The frame memory 48 is divided into two parts according to the size of the frame memory 48, and the left divided area and right divided area are transferred to the frame memory 48 in a time-division manner according to instructions from the keyboard 12, and are displayed separately as a left divided area and a right divided area.

After the user confirms the contents of the document, the main control section 10 causes the display screen control section 24 to perform thinning processing by inputting an end signal from the keyboard.

Thinning means that the thinning processing unit 50 reduces the data in the display memory to 1
The result is transferred to the frame memory 48, and the screen returns to the display screen of the entire document based on the thinned data.

The above operations can be performed after creating a print image from document data for each page.

In this case, a document format management table 5B may be provided for each page.

Note that this invention is not limited to the embodiments described above, and can be modified in various ways without changing the gist of the invention.

Although the area to be registered is a rectangular area, an area other than a rectangle may be registered.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to provide a document data editing device that can display a document in which vertically written characters and horizontally written characters are mixed in an easy-to-view orientation on a display that does not have a scrolling function.
