Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing apparatus and method capable of outputting characters by performing a deformation process.

[Prior Art] Conventionally, as a method of expressing a character pattern, a method of using a dot pattern or a method of expressing a character pattern by arrangement of contour coordinate data of the contour shape has been generally used. Deformation processing such as rounding processing for character patterns is performed on those data.

[Problems to be Solved by the Invention] However, the conventional character processing device performs a uniform process on a given character pattern regardless of its type, and is not versatile. Attempting to have it requires a user to perform a complicated operation, and cannot respond to various requests in the shape deformation processing.

If it is determined that the first character type has not been transformed, or the first font type transformation processing has not been performed, an output unit that outputs characters is provided.

Further, the character processing device of the present invention includes a determination unit that determines whether a character to be output is an external character, and performs a deformation process when the determination unit determines that the character to be output is an external character. And output means for outputting a character by performing a deformation process when the character to be output is determined not to be an external character by the determination means.

Further, in the character processing method of the present invention, the character to be output is a character of the first character type or the first
A determining step of determining whether or not the character is a character of the first character type; and determining that the character to be output is a character of the first character type or a character of the first type in the first determining step. Or the first font type is transformed, and the character to be output is not a character of the first character type or a character of the first font type in the determination step. And a step of outputting a character without performing a first character type deformation process or a first typeface deformation process.

Further, the character processing method of the present invention includes a determining step of determining whether a character to be output is an external character, and when the character to be output is determined to be an external character in the determining step, does not perform a deformation process. And outputting the character by performing a deformation process when the character to be output is determined not to be an external character in the determination step.

[Example] Hereinafter, an example of the present invention will be described in detail and specifically with reference to the drawings.

FIG. 1 is a drawing that best illustrates the features of the present invention. In the figure, 1 is a central processing unit (CPU), 2 is a read only memory (ROM), 3 is a readable and writable memory (RAM), and 4 is a keyboard (K
B), 5 is a display device (CRT), 6 and 7 are external storage devices (FD and HD), and 8 is a system bus for transmitting and receiving data between the devices.

The program of this device (for example, FIG. 2, FIG. 3,
(Represented by a flowchart in the figure) exists in the ROM 2 or the RAM 3, and the CPU 1 performs a target process while sequentially reading out a program through the system bus 8.

FIG. 2 is a flowchart showing an example of the control means of the present embodiment. Using this flowchart, the operation of the present apparatus will be described in the following order.

First, the process represented by this flowchart is started by an input instructing to perform a character pattern deformation from KB4.

First, in step S1, the character pattern and its character code are stored in ROM2 or RAM3 or an external storage device.
It is input from FD6 or HD7 and stored in the designated area of RAM3. Next, in step S2, a character type is specified from the character code. At this time, the character type is specified by referring to a table showing the correspondence between character codes and character types as shown in FIG. This character type refers to hiragana, kanji, and the like.

Next, in step S3, the typeface information is read from the designated area of the RAM3. At this stage, character code, character type, and typeface information corresponding to the character pattern can be obtained. This font includes Mincho, Gothic, "COUR
IER "," CUBIC "," ELITE "," PICA "," MICRON ", and the like.

Next, in step S4, the case is classified according to the character typeface, and the processing corresponding to each typeface is continued.

FIG. 3 is a flow chart showing the flow of processing in the case of Mincho.

In step S5, Mincho type characters are further classified by character type. Next, in step S6,
Corresponding processing is performed for each classified character pattern classified by character type and typeface.

FIG. 4 is a flowchart showing the flow of processing in the case of hiragana. In the case of Hiragana, the procedure of character outline rounding processing is performed in RAM3 or ROM2 as step S7.
Or read from the external storage device FD6 or HD7,
Processing is performed on the contour data.

The rounding process referred to here is a process for performing the rounding process of the contour data as shown in FIG.

Finally, in step S8 in FIG. 2, the processed contour data is stored in another area of the RAM 3 or in an external storage device.
Output to FD6 or HD7 and end the entire process.

Character patterns targeted by the above series of processing procedures are:
It may be a dot pattern or an outline pattern expressing a character outline.

As an example to which this processing procedure can be applied, there is a character processing apparatus as described in Patent Application (2) filed on February 27, 1989.

The invention described above is to automatically perform contour extraction from a dot font pattern of a character, generate contour data as a contour list, process the contour list by a processing group as a filter group, and then generate a smooth outline font. . At this time, in the processing in the filter group, when it is desired to select a processing procedure using information on the character type and the font of the character pattern, the method of the present invention can be applied.

FIG. 6 shows the character outline pattern of the character "A" whose character type is Hiragana and the font type is Mincho, and the character "A" similar to the above pattern whose character type is the external character and the font type is registered as Mincho. This is an example where the processing procedure is changed according to the present invention. The portion indicated by the arrow in the figure is the portion subjected to the rounding process.

As shown in the figure, the characters registered as Hiragana
A beautiful font is generated by performing the processing according to the flowcharts of FIGS. 2, 3 and 4 and rounding off the corners. Since such processing is not performed, there is no change in the output pattern. This is because performing the rounding process on the external character pattern does not always lead to the improvement of the beauty of the font. Note that the rounding process used herein refers to, for example, a process as shown in FIG.

The same thing as FIG. 6 can be applied to the alphabetic pattern “a” as shown in FIG. When the alphabetic pattern "a" is registered as Mincho-type alphanumeric characters, and the process of transforming Mincho-type alphanumeric characters in FIG. 3 is performed by rounding the corners in the same manner as described above, the modification as shown in FIG. Done.

Through the above series of processes, different conversion processes corresponding to the character type or typeface of a character can be automatically selected and applied to a given character pattern.

[Other Embodiments] In this embodiment, the processing procedure is selected according to the character type and typeface of the character. However, it is needless to say that the processing procedure can be selected based on other information attached to the character such as the character size.

[Effects] As described above, according to the present invention, a character can be output by performing a deformation process suitable for a character type or a typeface.

In addition, characters can be output without performing deformation processing on external characters.
