[Industrial application field]

The present invention relates to an end point shape changing method for a character creation device, and more particularly to an end point shape changing method for a character creation device that arbitrarily changes the end point shape of a character created by the character creation device.

In recent years, in-house printing, DTP (D
There is an increasing number of devices that hold character fonts in a vector format in which changing points on the contours of characters are represented as vector data, ranging from fonts to word processors.

In this way, when character fonts are stored in vector format, the amount of character data for one character is reduced compared to the character data in the full dot format that has been used in the past, and character data can also be stored for characters of different sizes. By enlarging or reducing vector character data of a basic size in a processing device, there is no need to prepare character data of various sizes, and a large amount of data can be reduced overall.

Although the amount of data has been reduced by the realization of vector characters, and the user needs to handle more characters and fonts are increasing year by year, it is impossible for manufacturers to cover all of them. Character creation devices that allow users to create the desired characters themselves are attracting attention because of the long delivery times and high costs when ordering them.

[Conventional technology]

In order to create one typeface in Japanese, compared to European languages, it is necessary to create a significantly larger number of characters. The number is about 100 characters/font for European languages, including symbols, but for Japanese, about 8,000 characters/font are required. Therefore,
It takes a lot of time and effort to create a new design and convert it into data when creating a new typeface, but some typefaces can create different typefaces by changing the shape of the end points. .

The square font shown in FIG. 7(A) can be changed to the round font shown in FIG. 7(B) by simply changing the shape of the end points of the characters.

It can be changed to a different body.

With conventional character creation devices, for example, when changing a square Gothic typeface to a round Gothic typeface, manual editing work is performed on each of the end points 10a to 10f of the square Gothic typeface. The characters had been changed to .

[Problem to be solved by the invention]

In the conventional apparatus, editing work must be performed manually for all endpoints of a character, resulting in a problem that the amount of editing work becomes enormous.

The present invention has been made in view of the above points, and an object of the present invention is to provide an end point shape changing method for a character creation device that changes the end point shape of a character automatically and at high speed.

[Means to solve the problem]

FIG. 1 shows a principle diagram of the system of the present invention.

In the figure, vector character data storage means 1 stores vector character data in which coordinates of displacement points of character outlines are expressed as vectors.

The flag adding means 2 adds a flag to the vector character data to indicate the end point data of the character of the vector character data.

The end point shape storage means 3 registers and stores vector data of the outline shape of the end point portion of a character.

The data processing means 4 processes the vector character data by changing each endpoint portion designated by the flag of the vector character data into vector data corresponding to the endpoint shape selected from the endpoint shape storage means 3.

[Effect]

In the present invention, since the flagged end α portion of vector character data is changed according to the end point shape of the data processing means 4 or the end point shape storage means 3, the end point shape of the character can be changed automatically and manually. Since there is less editing work required, high-speed processing is possible.

[Embodiment] FIG. 2 shows a block diagram of an embodiment of a character creation device according to the present invention.

In the figure, a vector character data storage section 20 stores vector character data in which the coordinates of the displacement points of the outlines of each character of the font as shown in FIG. 3 are expressed as vectors. The second vector character data is converted into full-dot character data by the data converter 21 and then transferred to the full-dot character data storage unit 2.
Further, the full-dot character data in the full-dot character data storage section 22 is converted into vector character data by the data conversion section 21 and stored in the vector character data storage section 20.

The vector character data read from the vector character data storage section 20 is displayed on the display section 25 through the vector character data processing section 23 and the drawing memory 24. When looking at a character as shown in FIG. 3 displayed on the display section 25 and specifying the end point shape starting points S1 to S6 and the end point shape end points El to E6 of each end point of the character, this instruction input can be performed using the input control i. The data is supplied to the vector character data processing section 23 through the wholesale section 27.

As a result, the vector character data processing unit 23 is configured as shown in FIG.
As shown in A), among the sequence of points along the character contour of vector character data, the above-mentioned end point shape starting point and ending point S1 to S6.
An end point shape start point flag S and an end point shape end point flag E are added for El to E6, respectively.

In addition, the input section 26 can be used to select an arbitrary end point, for example, an end point shape starting point,
End point S6. Select the end point of E6 and create a contour line shape (end point shape) of an arbitrary end point portion. This endpoint shape vector data is supplied to the vector character data processing section 23, where it is coordinate-converted into xy coordinates such that the starting point is on the origin and the ending point is on the X axis. Here, the end point shape start point, end point S6. Figure 5 (A) shows the X and Y coordinates of E6.
As shown in FIG.

Convert to y coordinate.

The vector data is registered and stored in the endpoint shape storage section 28 from the vector character data processing section 23.

Multiple types of vector data of this end point shape can be registered.

Next, when changing the end point shape of a character as shown in FIG. 3, the input section 26 selects the end point shape registered in the end point shape storage section 28 and instructs automatic correction. With this selection, the vector character data processing unit 23
The vector data of the selected end point shape is extracted and stored in the end point shape calling section 29, from which it is supplied to the vector character data processing section 23.

Vector character data J] [I engineering section 23 selects the end point shape starting point flag S of the vector character data shown in FIG.
from the addition position of the end point shape end point flag E to the addition position of the end point shape end point flag E are changed using vector data of the end point shape from the end point shape calling unit 29. In this case, the end point shape start point (Sl-S6) and end point (El to E6) of each end point on the character, and the start point (0, 0) and end point (x, , O) of the called end point shape, respectively.
), coordinate transformation as shown in FIG. 5(C) is performed using the following equation.

However, l is a subscript for distinguishing the end points, XE, -X.

X.

In equation (2), expansion or contraction is performed by the coefficient a,
A rotation is performed by an angle φ.

As a result, the vector character data in FIG. 4(A) is changed to the end point shape called from the addition position of flag S to the addition position of flag E, and becomes the vector character data in FIG. 4(B). The characters displayed on the display section 25 are automatically changed from the square Gothic font shown in FIG. 6(A) to almost the round Gothic font shown in FIG. 6(B).

Further, the vector character data processing unit 23 stores the vector character data shown in FIG. 4(B) in the vector character data storage unit.

However, the full-dot character data processing section 30 displays the full-dot character data from the full-dot character data storage section 22 on the display section 25 through the drawing memory 24, and displays the full-dot character data from the full-dot character data storage section 22 on the display section 25.
6, the full dot character data is processed by control through the input control unit 27, and the full dot character data is stored in the full dot character data storage unit 2.
Store in 2.

In this way, since the flagged endpoint portion of vector character data is changed according to the endpoint shape of the data processing means 4 or the endpoint shape storage means 3, the endpoint shape of the character can be changed automatically, and manual editing can be avoided. Since there is less work involved, high-speed processing is possible.

〔Effect of the invention〕

As described above, according to the end point shape changing method of the character creation device of the present invention, the end point shape of a character can be changed automatically and at high speed, requiring very little manual editing work, and is practical. Extremely useful.
