Abstract

PURPOSE:To easily edit an article covering the right and left pages by displaying an editing subject on a bit map display device approximately in an actual size, in a spread form and in a state equivalent to a printed state. CONSTITUTION:A bit map memory area of a main storage circuit 3 is decided from the dot pitch of a bit map display device 5, and a memory area equivalent to two sheets of forms is secured when an editing task is designated in a spread form. The editing subject data such as the characters, the graphics, the images, etc., received from a floppy disk device 8 are converted into the dot data so that an editing subject is displayed approximately in an actual size based on the layout data on the positions, the forms of characters, the height of characters, etc., given to the editing data. Then the dot data are written into the bit map memory area. The evolved contents are displayed on a display device 5 via a video control circuit 4. In such a constitution, the contents of an article covering both right and left pages can be easily edited.

Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention is applicable to bitmap display devices for characters, graphics, etc.
The present invention relates to a device that performs editing while displaying an object to be edited, such as an image.

(Prior Art) In a conventional electronic typesetting device, the content of a page or sheet of paper to be edited is displayed on a display device.

(Problem to be Solved by the Invention) For this reason, for example, when editing a magazine or the like, it is extremely difficult to edit an article that spans left and right pages in a two-page spread.

Furthermore, even if characters are specified in various fonts, character heights, etc., they are displayed in standard fonts on the display screen, making it difficult to get a clear image of how they will actually be printed, which is inconvenient.

The present invention has been made to solve these problems, and its purpose is to provide a device for editing by displaying the actual printing time, size, font, etc. on a display device in a double-page spread state. It is something to do.

(Means for Solving the Problems) In order to solve the above problems, an electronic editing device according to the present invention includes:
In the main memory circuit of the main processor, a bitmap memory area is secured that corresponds to the dot pitch of the bitmap display device and can accommodate at least two specified sheets of paper in a spread format. Based on the layout data of the position, font, and height of the characters on the paper assigned to this data, arithmetic processing is performed so that the editing target is displayed in approximate actual size, and the data is written as dot data in the bitmap memory area. At the same time, the correspondence between each data to be edited and the address of the bitmap memory area is managed and stored, and the range within the bitmap memory area specified by the display range specifying means is converted into a video signal and displayed on the bitmap display device. It is characterized by causing

In addition, dot data in the bitmap memory area in the range specified by movement of the cursor etc. on the display screen of the bitmap display device and the bitmap memory area corresponding to the movement position based on the movement data specified by the cursor etc. It may be provided with a means for overwriting display by performing a logical sum operation with the dot data.

Furthermore, it is desirable to have means for changing the layout data to be edited in a specified range by moving a cursor or the like on the display screen of the bitmap display device.

(Function) The object to be edited, such as characters, figures, images, etc., is displayed on a bitmap display device in substantially actual size, in a two-page spread state, and in a state equivalent to a printed version.

Furthermore, it is possible to select an arbitrary area on the display screen and move the selected area to overlap another area.

Additionally, you can select any area and change the font and height of the font.

Since the correspondence between the address of the bitmap memory area and the data to be edited is managed and stored, the contents edited on the screen can be saved.

(Example) Embodiments of the present invention will be described below based on the accompanying drawings.

FIG. 1 is a system configuration diagram of an electronic editing device according to the present invention.

The electronic editing device 1 is connected to a main processor 2, a main memory circuit 3, a video control circuit 4, a bitmap display device (hereinafter simply referred to as a display device) 5, and a human output control microprocessor (IloMPU) 6. It consists of input and output equipment.

In this embodiment, the input devices include an image scanner 7, a floppy disk device 8, a keyboard (K/B) 9,
A mouse 10 and a printer 11 as an output device are provided.

Main bus 1 connects main processor 2, main memory circuit 3, video control circuit 4 and human output control microprocessor 6.
2, and the display device 5 is connected to the video control circuit 4. In addition, an input/output bus 1 is connected between the input/output control microprocessor 6 and each input/output device 7 to 11.
Connected by 3.

In this embodiment, the operating system (O5) and application programs are input from the Flobi disk device 8, and these are resident in the main memory circuit 3 via the input/output control microprocessor 6. In addition, the dot patterns of characters are also stored in the main memory circuit 3.
It is configured to be moved inside.

Document data created with a word processor (not shown) or the like is input from a floppy disk device 8 using a floppy disk as a medium. Image data other than character codes may be included. Note that document input may be performed directly using the keyboard 9 of the electronic editing device 1, and image data may be directly input using the image scanner 7.

The main processor 2 displays on the display device 5 guidance on the paper size to be edited and whether to edit in two-page spread format, and when these are specified, the necessary bitmap memory area is secured in the main memory circuit 3. . The bitmap memory area is determined based on the dot pitch of the bitmap display device 5, and a memory area for two sheets of paper is secured when double-page editing is specified.

Then, the data to be edited, such as characters, figures, images, etc., manually inputted from the floppy disk device 8 is determined based on the layout data of position, font, and height of the characters given to the editing data, so that the data to be edited is approximately the actual size. Convert it to dot data so that it is displayed as an image, and write it to the bitmap memory area.

Character data including kanji, symbols, etc. can be printed using a dot pattern corresponding to the character code (for example, 16Xl [i or 24X
24 dots) specified through calculation processing.
This conversion work is performed by the main processor 2.

The contents developed as dot data in the bitmap memory area in the main memory circuit 83 are displayed on the display device 5 via the video control circuit 4. If two sheets of paper cannot be displayed on the screen, use keyboard 9 or mouse 10.
The display range can be selected by .

It also has a function of moving a cursor on the screen using a mouse 10 or the like to move a specified range of data to be edited.

The main processor 2 stores the original data to be edited manually from the floppy disk device 8 or the like in the main memory circuit 3, and also expands this original data into dot data to which address in the bitmap memory area. Similarly, correspondence information regarding the number of times and times is stored in the main memory circuit 3.

Therefore, when movement of a specific range is requested, the main processor 2 performs the movement process while performing an OR operation between the dot data of the range to be moved and the dot data of the moving light. At the same time, the main processor 2 updates the position data on the paper that is added to the original data.

Furthermore, when a request is made to change the font or character height of a specified range of characters, the main processor 2 performs arithmetic processing again based on the character dot pattern and writes the changed dot data to the bitmap memory area. , is configured to update the font and font height data attached to the original data.

With the above configuration, as shown in the explanatory diagram of FIG.
In addition to displaying two sheets of paper spread out on the screen, you can place and edit shapes and image data across both sheets of paper, and you can also write text on top of the shapes and image data. You can edit overwriting and change the font and height of characters at specific locations.

(Effects of the Invention) As explained above, the editing device according to the present invention displays the contents of two sheets of paper on the display screen in a two-page spread state and with approximately the same actual size as the printed version, so that articles that span the left and right pages can Contents can be easily edited.

In addition, since the selected range is moved in overwrite mode, it is possible to overlay image data and document articles, etc. Also, the font and height of the selected part can be changed, and the changed content can be changed. Since each page can be saved, editing for two pages can be done at the same time.
