Abstract

PURPOSE:To prevent the generation of a boundary line between adjacent images when these images are inverted by applying the coordinate transformation to the right-left coordinate value and the upper-lower coordinate value of an image area based on the different expressions of transformation. CONSTITUTION:A coordinate transformation means 8 applies the coordinate transformation to the coordinate values of the right, left, upper and lower sides forming an image area with use of different expressions of transformation respectively. When an area to be inverted is specified by the means 8, a CPU 7 calls a program out of a memory device 6 to invert an image and computes the data on the corresponding image area to invert the image. As a result, a boundary line is never produced between the adjacent images when these images are inverted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document creation device having a function of displaying characters or figures on a display screen.

[Conventional technology]

2. Description of the Related Art Conventionally, document creation devices have been known in which images of characters or figures to be printed are displayed on a screen, and a user can create a document while viewing these images. In this type of document creation device, when creating a document, it may be operationally effective to change the display magnification of characters and figures displayed on the screen. For example, when the paper image cannot be completely displayed on the screen, it may be displayed in a reduced size, or it may be enlarged and displayed in order to draw a detailed figure. In this case, data regarding font size, paper size, etc. is held within the device, but the data units are the units of the display device or the units used for the displayed font. . However, in general, the dot density of the screen of a display device is coarser than that of a printing device such as a printer, and therefore, depending on the processing performed on the document, the display device may not be able to handle the dot density. For example, fine adjustments such as line pitch and character spacing are difficult to make on the screen, and may look bad when printed out. Therefore, the unit of data is changed to a unit that does not depend on the display device or printing device. A document creation device that is equipped with a computer is being considered.

In such a document creation device, the minimum unit inside the arranging device (hereinafter referred to as internal unit) and the minimum unit of the display device (hereinafter referred to as external unit) are set and converted using the conversion formula described later. , is performing the process of converting from internal units to external units.

For example, if the minimum unit inside the device is 1/100 mm and the minimum unit of the display device is 1/10, the formula for converting the internal unit to the external unit is: External unit - Internal unit / 10 ... Formula (1 ) (rounded to the nearest whole number). Therefore, when converting a length of 100 mm in internal units to external units, it becomes 100/10-10 cm.

[Problem to be solved by the invention]

However, when further inversion processing is performed on characters and figures displayed in a reduced size on a screen, the following problems may occur.

FIG. 3 is an explanatory diagram showing the coordinate system of the image displayed on the screen. Here, the character A with a width of 100 internal positions
An example in which two are arranged horizontally will be explained. In FIG. 3, the X coordinate values of the first character A are 1000 on the left and 199 on the right, and the X coordinate values of the second character A are 200 on the left and 299 on the right. At this time, when coordinate transformation is performed using the above equation (1) in order to invert the first character, the X coordinate value becomes 10 on the left side and 20 on the right side.

Similarly, the X coordinate value of the second character is 20 on the left and 30 on the right.
becomes. Since the reversal of the character A is performed on the area surrounded by each coordinate value of the Only the portion will be flipped twice. Therefore, only the part 20 is not inverted as a result, and there is a problem in that a boundary line is created between characters. In this example, the numbers below the decimal point are rounded off, but the same result will be obtained even if the numbers below the decimal point are rounded down or rounded up. For example, the coordinate value on the right side of the first character A is 200, and the coordinate value on the left side of the second character A is 200.
If it is 01, even if the decimal point is rounded down, the same value (20) will be obtained. Note that the coordinates in the upper/lower y-axis direction are omitted to simplify the explanation, but
Similarly, when characters are arranged vertically, there will be borders between the characters.

SUMMARY OF THE INVENTION An object of the present invention is to provide a document creation device that does not create boundaries between adjacent images when performing reversal processing.

[Means to solve the problem]

In order to solve the above-mentioned problems, in the document creation device according to the present invention, when performing reversal processing on images such as characters and figures displayed side by side horizontally or vertically, the right side and left side of each image area, as well as the A coordinate conversion means is provided which applies different conversion formulas to the upper and lower coordinate values and converts the coordinates based on each conversion formula.

[Effect]

Different transformation formulas are applied to the filling areas of images placed next to each other, but specifically, the conventional transformation formula is applied to the coordinate values on one side of the image, and the transformation formula is applied on the other side. For the coordinate values on the side, a different conversion formula is applied.

For example, in Figure 3, the conversion formula for the left side coordinate value of character A is the conventional formula (1), and the conversion formula for the right side coordinate value is: External unit - ((Internal unit + 1) / 10) - 1 (Round off to the nearest whole number.) Then, the internal coordinates on the right side of character A are ((internal unit +
1)/10), the second character A is converted to the closest value that can be adjacent to the left side, and then, by the operation of -1, it is converted to the closest value that can be adjacent to the right side.

The value converted using the above-mentioned conversion formula will never become the same numerical value in adjacent coordinate values even if the numbers below the decimal point are rounded off or rounded down or rounded up. The same applies to the conversion equations for the upper and lower sides of the image.

Therefore, the left/right coordinate values on the X coordinate axis and the upper/lower coordinate values on the y coordinate axis, which constitute one image area, are transformed using different conversion formulas, and based on the transformed coordinate values, By inverting the image, it is possible to prevent the same part from being inverted twice.

〔Example〕

An embodiment of the document creation device according to the present invention will be described below.

FIG. 1 is a block diagram showing the basic configuration of a document creation device according to the present invention. This document creation device consists of a CRTI for displaying characters, figures, etc. on the screen, and a CRT.
A CRT control unit 2 that controls the display on the I, a keyboard device 3 that inputs commands, character strings, numerical values, etc.
a pointing device 4, such as a mouse, for selecting a display area etc. displayed on the TI with a cursor;
It is composed of a disk device 5 in which a group of dictionaries for hiragana-kanji conversion are stored, a memory device 6, and a CPU (central processing unit) 7.

A memory area (not shown) of the memory device 6 stores programs such as an operating program that manages the basic operations of this document creation device and various application programs, as well as human input from the keyboard device 3 and pointing device 4. Data such as characters and numbers are stored.

The CPU 7 is a circuit that controls the entire device and performs arithmetic processing on various data.
A program connected to instructions from the pointing device 4 is read from the memory device 6, and arithmetic processing is executed on the manually entered data. In addition, when inverting adjacent images, the CPU 7 applies different conversion formulas to the right and left sides, as well as the upper and lower coordinate values of each image, and converts the coordinates based on each conversion formula. It includes coordinate conversion means 8 for performing the following.

Next, the coordinate value conversion formula applied by the coordinate conversion means 8 will be explained. In the above-mentioned Figure 3, if the conversion formula for the left coordinate value of letter A is the same as before, the conversion formula for the right coordinate value is: External unit - Round ((internal unit + 1) / 10) -
1...Equation (2) (round off to the nearest whole number). Note that Round( ) represents a function that rounds off a numerical value below the decimal point.

Also, if the conversion formula for the right-hand coordinate value of letter A is the same as before, the conversion formula for the left-hand coordinate value is external unit - Round
((Internal unit - 1)/10) + 1...Formula (3) (round off to the nearest whole number).

To explain equation (2) using Figure 3, first, the internal coordinates on the right side of the first character A are ((internal unit + 1)/1
0) to convert it to the closest value adjacent to the left side of the second character A, and then convert it to the closest value adjacent to the right side by setting that value to -1. are doing. According to this, even if the number below the decimal point is rounded off, rounded down or rounded up, the converted value will not be the same value, so the same part will not be inverted twice. do not have. This also applies to equation (3).

Further, by applying the same formula to converting the values of the upper and lower coordinate values on the y-axis, it is possible to prevent the values from being inverted twice at the same portion.

The coordinate conversion means 8 described above performs coordinate conversion by applying different conversion formulas to four types of coordinate values, ie, left side, right side, upper side, and lower side, which constitute one image area. When the area to be inverted is specified by the coordinate conversion means 8, the CPU 7 calls a program for inverting the image from the memory device 6, calculates the data of the corresponding image area, and inverts the image.

Next, the processing procedure of the coordinate conversion means 8 when converting the coordinate values of the image area to be reversed will be explained using the flowchart shown in FIG.

First, the coordinate conversion means 8 converts the given coordinates into the abscissa (X
If the coordinate is an abscissa coordinate, it is determined whether it is a left coordinate (step 101).
Step 1o2). Here, if the coordinates are on the left side, the left side coordinates are converted (step 103), and if the coordinates are not on the left side, the right side coordinates are converted (step 104).

Further, in step 101, if the given coordinate is not the abscissa coordinate, it is cut off from the ordinate (y?# coordinate), and it is further determined whether the given coordinate is the upper coordinate (step 105). Here, if the coordinates are on the upper side, the upper coordinates are converted (step 106); if the coordinates are not on the upper side, the lower coordinates are converted (step 107). Coordinate conversion means 8
In step 108), each time the coordinate transformation process is completed, it is determined whether the coordinate transformation process has been performed four times.
The process from step 101 is repeated until the transformation of the four coordinates constituting the image area to be reversed is completed.

〔Effect of the invention〕

As explained above, in the document creation device according to the present invention, different conversion formulas are applied to the coordinate values of the right and left sides and the upper and lower sides of the image area, and the coordinates are calculated based on each conversion formula. Since the conversion is performed, even if the numbers below the decimal point of the converted value are rounded off,
Or, even if you round down or round up, adjacent coordinates between adjacent images will never have the same value, and the same part will be 2
It is never reversed. Therefore, it is possible to provide a document creation device that does not create a boundary line between adjacent images even when the images are inverted.
