Abstract

PURPOSE:To automatically arrange a character string corresponding to an optional curve by calculating the length of the line of a line graphic or the line of a closed graphic outline and arranging the characters of the character string in specific relation according to the line length. CONSTITUTION:In a uniting process for a closed graphic and characters, it is checked whether or not a line drawing selected in S0501 is curve data and when so, curve data are converted into straight line group data in S0502. When the graphic is straight line data on a straight line, polygon, etc., the line length of the line is calculated in S0503. In S504, the positions of the respective characters are calculated from the number of characters of the character string and the character size of each character obtained from a character string data management data and the calculated line length. In S0505, the angle of rotation of each character is determined according to the gradient of the straight line of the straight line group corresponding to the calculated character position. In S0506, a character pattern read out of a font memory is moved and rotated according to the obtained character position and the angle of rotation and written in a buffer memory.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character string arranging method. In particular, the present invention relates to a technique used for arranging character strings along a line in a word processor having a desktop publishing display function (DTP display function) to create a presentation document or a leaflet document.

[0002]

2. Description of the Related Art For a presentation document or a leaflet document, it is necessary to arrange a figure and a character in association with each other.
It has been proposed in the past. In a conventional document creating apparatus for creating a document including characters, figures, images, etc., a character string 0802 is converted into a figure 08 by a mouse operation as shown in FIG.
It was integrated by moving and arranging it on 01.

That is, it is well known that the character string 0802 is moved so that the graphic 0801 and the display position are overlapped with each other, and then the two are integrated into one and processed as one object. Note that the square black dots in FIG. 8 are displayed in order to make it easier to understand the existence of the area with each figure / character.

However, this integration apparently handles only two data as one data, and when the user wants to create the data as shown in FIG. 9 (a), the user himself / herself writes the character string one by one. After determining the size of the, it was necessary to place it in the appropriate position. Further, when it is desired to display as shown in FIG. 9 (b), as shown in FIG. 9 (c), first, a graphic 0901 is created, then characters 0902 to 0906 are created, and then each character is processed by rotation or the like. Had to be done and placed in the proper position.

As described above, the efficiency of creating a character string on a line often used in a presentation document or a leaflet document is very poor. To evenly arrange a character string along an arbitrary curve, create this arbitrary curve, enter the character you want to arrange, and use the keyboard or mouse to move it character by character on this curve. , I had to operate while looking at the screen so that the character strings were even.

Therefore, it is difficult to arrange the character strings along the arbitrary curve so as to be exactly equal, and when the character string is updated or the shape of the curve along which the character string is desired to be updated is updated. , It is necessary to redo all the arrangement of character strings, and the processing efficiency is very poor. It should be noted that regarding the arrangement of a character such as a line or a polygon and a character in association with each other, it is also shown in the following materials.

Japanese Laid-Open Patent Publication No. 4-347779 (G06F15 / 6
2) shows a technique for setting the size and position of a character written in a graphic according to the size of the graphic.
Further, Japanese Patent Application Laid-Open No. 1-194076 (G06F15 / 60) discloses a technique of arranging a frame of a character to be written in a figure from the center of gravity of the figure. Also, the actual Kaihei 1-3
Japanese Patent No. 5448 discloses a technique of arranging pictograms according to the pattern of a figure.

Further, Japanese Patent Application Laid-Open No. 61-282974 (G
06F15 / 66), once the characters are placed on the line figure, the relationship between them is memorized, and when the line figure is deformed,
In response, techniques for rearranging characters have been shown.

Next, details of the integrated processing unit 0106,
That is, the details of S0403 and S0404 will be described with reference to FIGS.
Will be described with reference to. First, it is checked whether the line figure selected in S0501 is curve data such as a spline or Bezier. If it is curve data, the process proceeds to S0502, and if it is straight line (polygon) straight line (group) data, the process proceeds to S0503. .

In step S0502, the curve data is converted into straight line group data by a known method. In S0503, the line length of the line is calculated. In the case of a curve, the straight line lengths are calculated for all the lines using the straight line group data obtained in S0502. S
The number of characters 0210 and the character size (width) of each character obtained from the character string data management table (Fig. 2c) in 0504.
The position of each character is calculated from 0209 and the line length calculated in S0503 so that the character string is evenly arranged on the line curve (a calculation method will be described later).

In step S0505, the rotation angle of each character is determined from the inclination of the straight line in the line group corresponding to the character position calculated in step S0504. At this time, the rotation angle is determined based on the designated information by the character arrangement designating means (not shown). For example, when the arrangement of characters is designated in the direction normal to the line curve, the characters are rotated so that the arrangement is as shown in FIG. When the arrangement of characters is specified in the tangential direction with respect to the line curve, the characters are rotated so that the arrangement is as shown in FIG. When the character arrangement is not specified, the rotation processing is not performed and the arrangement is as shown in FIG. 7C.

In step S0506, the character pattern read from the font memory (not shown) is moved and rotated based on the character position and rotation angle information obtained in steps S0504 and S0505 and written in the image buffer. Next, the method of calculating the uniformly arranged position of each character in S0504 of FIG. 5 will be described with reference to the flowchart of FIG.

In FIG. 6, the coordinates of the left center of each character are calculated as an example. Check the number of characters in the character string in S0601
If there is only one character, the process proceeds to S0602, and the coordinates are obtained such that this one character is located at the center of the line curve. If the number of characters is 2 or more, the process proceeds to S0603. In S0603, the coordinates of the starting point of the line curve are obtained as the first character position of the character string.

In step S0604, the character spacing s is calculated. Figure 5
If the line curve length calculated in S0503 is L, the number of characters in the character string is N, and the total width of all characters in the character string is W, then s =
(L-W) / (N-1). In S0606, the distance from the first character to the character whose position is to be calculated is calculated, and S06
At 07, the coordinates on the line curve distant from the start point of the line curve by the distance are calculated and used as the coordinates of the character.

For example, the distance from the first character to the nth character is l (n), and the nth character width is w (n).
Then, l (n) = 1 (n-1) + w (n-1) + s. That is, the coordinates on the line curve distant by l (n) from the starting point of the line curve are the coordinates of the nth character. In this embodiment, even if the character strings are evenly arranged once along the curved line and then the character strings are updated or the shape of the curved line is updated, the evenly arranged positions of the character strings are automatically calculated and repositioned. To do. For this reason,
It is possible to accurately and evenly arrange the character strings and reduce the processing time. Especially when the figure is a line figure,
The character string data is processed and rearranged along the trajectory of the line of the figure.

In this embodiment, in the case of the closed figure, the character string is arranged inside the closed figure. However, the present invention is not limited to this. For example, in the case of the closed figure, the contour line of the closed figure is used. The character string may be arranged by calculating the arrangement position based on the length. Further, in this embodiment, the character string is arranged on the line,
The present application is not limited to this, and for example, character strings may be arranged at positions separated along a line.

Further, in the present embodiment, the graphic and the character string are displayed, but the display of the graphic may be erased after this integration processing so that only the character string is displayed. The display of the graphic is erased by changing the attribute of the graphic to transparent. Further, in the present embodiment, the character strings are evenly arranged, but the present application is not limited to this, and for example, the character strings may be arranged so that the intervals are gradually narrowed.

Further, although the character width of the character string is not changed in the present embodiment, the present invention is not limited to this. For example, the character width of the character string may be gradually narrowed and the character width of the character string may be decreased. You may arrange so that the point number of the character of a row may become small gradually.

[0045]

According to the present invention, the arrangement position of the character of the character string can be determined according to the line length, so that the user does not have to set the arrangement position of the character string, and the creation efficiency is improved. .
