Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus for processing image data such as characters and graphic images, and particularly having a vector font as font data.

[Conventional technology]

In general, when visual display of image-processed information in an image processing apparatus, for example, vector font information in which a position of each line segment information in one character is represented by a start position and an end position of a line segment corresponding to a dot position on a display screen is displayed. There has been proposed a device that stores and stores the information in a memory, and displays a character designated based on the vector font information on a display screen.

Display using vector font information is long, flat,
Various shapes such as italic and reverse italic can be modified.

[Problems to be solved by the invention]

However, in the conventional vector font information, since the character size ratio is predetermined for each character, such as JIS, it is impossible for the user to specifically transform a specific portion of one character as desired. There was a point.

Therefore, an object of the present invention is to solve such a problem and to provide a document processing apparatus capable of easily modifying predetermined vector font data into vector font data desired by a user. .

[Means for solving problems]

In order to achieve such an object, the present invention provides a character data input means for inputting character data, a storage means for storing the character data input by the input means, and the character stored in the storage means. Generating means for generating a character string pattern represented by a dot pattern using a vector font based on the data; and correcting a desired character pattern of the character string patterns generated by the generating means. And a changing means for changing the shape of the character pattern using a vector font based on the position information inputted by the position information input means. It is characterized by

Furthermore, the present invention is characterized in that the changing means changes the shape of the character pattern by moving a point or a width of a contour or a contour based on the position coordinates.

[Action]

In the present invention, for example, since the shape of a character input for document creation processing can be changed on the spot, the modification is easier than the modification of the vector font of a character generator or the like, and the content of document editing is highly functionalized. it can.

Moreover, the correction operation is further facilitated by changing the width of the outline of the character or moving the outline.

The feature point is moved to the fourth feature point shown in FIG. 6 (B).
Then, the x-coordinate y-coordinate of the feature point at the time when the click button is released, that is, the input position coordinate is the x-coordinate and y-coordinate of the corresponding feature point in the character in the shared area F2 instructed to be changed. Each value is rewritten (steps S11 → S12).

Therefore, return to step S8 and perform the recalculation of steps S8 to S9.
Performed by MPU / H6 and redisplay the corrected characters.

Although only the feature points are moved in this embodiment, if a contour moving mode such as changing the width of the contour is separately provided, the contour can be moved in the same manner, and the shape of the character can be changed more easily. Become.

When printing the character information that has been corrected in this way, MPU is added to the print font information based on the character information (character pattern information) stored in VRAM / H4 or the vector font information stored in PMEM / H15.・ Convert by H6 and store this font information in IMEM ・ H16. Then, the selection switch shown in FIG. 2 is switched from the IMEM / H16 in response to a print command from the operator, the font information from the IMEM / H16 is transferred to a desired printer, and the font information may be printed in a character form.

〔The invention's effect〕

As described above, according to the present invention, for example, the shape of the character input for the document creation processing can be changed on the spot, so that the modification is easier than the modification of the vector font of the character generator or the like, and the document editing can be performed. The contents of can be enhanced.

Moreover, the correction operation is further facilitated by changing the width of the outline of the character or moving the outline.
