56 dot enlarged font is a vector font conversion circuit
14 through a conversion procedure such as a contour extraction process and a contour line tracking process (here, a tracking scan in a counterclockwise direction starting from a contour point at the upper left corner), and X as shown in FIGS. 6 to 8.
-Converted into absolute vector data represented by a Y coordinate sequence (here, absolute vector data obtained by tracking and scanning counterclockwise starting from the contour point at the upper left corner) and further converted into relative vector data as shown in FIG. After the conversion, it is stored in the vector font storage unit 15. The contour extraction mechanism at the time of generating the vector font at this time is disclosed in Japanese Patent Application No. 62-21002, Japanese Patent Application No. 62-21003, Japanese Patent Application No. 62-21003, etc. The playback mechanism is disclosed in Japanese Patent Application
No. 162878 and Japanese Patent Application No. 62-244302.

As shown in FIG. 5 (A), the font vectorized by the vector font conversion circuit 14 has many irregularities on an edge portion, which is not preferable in design. Therefore,
The vector font stored in the vector font storage unit 15 is read into the vector graphic editor 16, and unnecessary irregularities on the edge portions are removed to form a beautiful form as shown in FIG. 5 (B).

FIG. 2 shows an editing processing screen of the vector font storage unit 15 at this time, and FIGS. 3 and 4 show modified examples.

Fig. 18 (a1, a2) shows the pattern transition state due to the creation (addition) of the entire contour forming the closed loop structure, and Fig. (B1, b2) shows the pattern transition state due to the deletion processing. FIGS. (C1, c2) show pattern transition states showing examples, and FIGS. 11 to 17 show each editing processing flow.

Here, as the editing processing screen of the vector font storage unit 15, as shown in FIG. 2, the entire editing target font is displayed in the right half of the display screen, and the editing font among the editing fonts is displayed in the left half. A part of the font whose frame is specified as the target is enlarged and displayed. When inserting a contour point, "Insert" is designated by a mouse cursor or the like in the work menu on the display screen shown in FIG. 2, and further, FIG. 3 (b)
As shown in (1), the position of the contour point to be inserted is designated by the cursor c. As a result, the corrected outline after the insertion of the outline points is displayed as shown in FIG. 3 (b).

To delete unnecessary contour points, specify [Delete] from the work menu on the display screen shown in FIG. 2 with the mouse cursor, and further delete unnecessary contour points as shown in FIG. Is designated by the cursor c. Thereby, as shown in FIG. 4 (b), the corrected outline after the deletion of the outline point is displayed.

Also, when correcting the contour points, specify [Correction] with the mouse cursor from the work menu on the display screen shown in FIG.
By moving the outline point to be corrected with the cursor c, the corrected outline dotted line is displayed.

Specific examples of these editing processes are shown in FIGS.
18 and the transition state diagram shown in FIG. 18, the data conversion state diagram shown in FIG. 9, the data structure diagram shown in FIG. 10, and the flow charts shown in FIGS. 11 to 17. Therefore, the description is omitted here.

The vector font data cleaned and corrected by the vector graphic editor 16 is stored in the cleaning vector font storage unit 17.

The vector font data after cleaning correction stored in the cleaning vector font storage unit 17 is converted into a dot font by a vector font reproducing circuit 18 with a dot matrix according to dot conversion magnification designation information xc. For example, a 10-point character required for a 400 DPI printer is 56 × 56 dots, but the vector font reproduction circuit 18 has 56/256 dot conversion magnification designation information xc.
By setting, an external character pattern of 56 × 56 dots can be easily created. Similarly, external character patterns such as 40 × 40 dots and 32 × 32 dots required for printers such as 300 DPI and 300 DPI are dot conversion magnification designation information xc such as 40/256 and 32/256.
Can be easily created by setting.

The external character pattern (for example, 24 characters) after the dot matrix conversion created by the vector font
× 24 dots, 32 × 32 dots, 48 × 48 dots, 56 × 56 dots,
80 × 80 dots) are stored in the converted dot font storage unit 19.

By using the above-described dot matrix conversion method according to the embodiment of the present invention, the same external character pattern having an arbitrary dot matrix configuration can be quickly obtained with a simple operation from the external character pattern already created with a certain dot matrix configuration.

Note that the above-described dot matrix conversion method for registered character types uses facsimile, typesetting,
It can be applied to image processing machines and the like.

[Effects of the Invention] As described above, according to the present invention, in order to create a new registered character type pattern that is enlarged from a registered character type pattern having a dot matrix configuration, the registered character type pattern is first enlarged, and then the enlarged. The registered character type pattern is once converted from the dot matrix configuration to a vector font pattern, and the outline can be edited by the user based on the converted character type pattern of the vector font pattern.

As described above, since the user and the contour can be easily edited with respect to the enlarged character type pattern having the dot matrix configuration, the process of creating a new registered character type pattern in which the registered character type pattern having the dot matrix configuration is enlarged can be performed easily and easily. Can be done quickly.
