DESCRIPTION OF THE PREFERRED EMBODIMENTS A character decoration device according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a diagram showing a configuration of a character decoration device according to an embodiment of the present invention.

In FIG. 2, the character modification device is an input device 11 composed of a keyboard for inputting characters and the like, a CPU (central processing unit) 12 for controlling various parts,
A CRT (display device) 13 that displays characters and the like, a document buffer 14 that stores input characters or processed characters, a print buffer 15 that expands outline data into a bit pattern, and a printer 16 that prints characters and the like. ,

Next, the operation of the character decoration device configured as described above will be described. When a character is input from the input device 11, a kana-kanji conversion device (not shown) creates a kana-kanji mixed sentence and stores it in the document buffer 14. The input characters are displayed on the CRT 13. When a print key (not shown) of the input device 11 is pressed, the CPU 12
Extracts the contents of the document buffer 14 character by character, and the character pattern corresponding to the extracted characters is stored in the character data storage device 1.
Take out from 7. The CPU 12 develops the character pattern in the print buffer 15 with the thickness set in the page buffer 18. The developed bit pattern is transferred to the printer 16 and finally printed.

Next, the outline of the modification processing by the character modification device of the present invention will be described. FIG. 3 is a diagram for explaining the outline of the modification processing of the character modification device of the present invention. First, FIG.
The outline data is read as shown in FIG. Next, as shown in FIG. 3B, character center information and character thickness information are created from the outline data.
Next, as shown in FIG. 3C, the created thickness information is converted into speed information, and vector information is created based on the converted speed information and center information. Finally, as shown in FIG. 3D, character data subjected to a predetermined modification processing according to the vector information is created.

Next, the above modification processing will be described in more detail. FIG. 1 is a flowchart illustrating a modification process by a character modification device according to an embodiment of the present invention.

First, in step S1, the document data pointer indicating the position of the character code is initialized.

Next, in step S2, the character size is extracted from the format information at the current cursor position and the character size is designated.

Next, in step S3, the character typeface is designated. Next, in step S4, various data of the paint system program, for example, a painting tool and a painting pattern are designated. FIG. 4 is a diagram illustrating an example of a paint system program. For example, as shown in FIG. 4, in a paint system program, dot data is written in the page buffer 18 by selecting a painting tool, selecting a painting pattern, and moving the mouse or pen. A brush, a pen, a brush, a spray, or the like can be selected as a painting tool. As the pattern to be applied, black solid, mesh, diagonal lines, etc. can be selected. Further, in a paint program, the character data can be subjected to a predetermined modification process depending on the speed at which the mouse or the like is moved. FIG. 5 is a diagram showing an example of character modification by the paint system program shown in FIG. If the speed of moving the mouse etc. is slow, thicken the dot data as shown in (a) of FIG.
As shown in (c), the density of dot data can be increased. Further, when the speed is high, the thickness of the dot data can be made thin as shown in FIG. 5B, or the density of the dot data can be made thin as shown in FIG. 5D.

That is, in the above paint system program, the mouse is used to interrupt the mouse at a constant time interval, and at the time of the interrupt, the relative position from the previous position is output. As the relative position, a method of returning in (x, y) relative coordinates, a method of returning in angle and length in polar coordinates, or the like is used. In addition, the distance moved is the amount of movement, that is, the speed, in a fixed time. Therefore, moving faster will increase the amount of movement, and moving slowly will decrease the amount of movement. On the other hand, when you practice with a brush, moving slowly will make the characters thicker, and moving faster will make them thinner. Therefore, depending on the speed of the mouse, when the distance between the two points is short, the two points are connected by a thick line, and when the distance is long, the two points are connected by a thin line. As a result, instead of the relative position and speed information output from the mouse, by providing vector information to the paint system program, the modification processing similar to the mouse operation can be performed.

Next, in step S5, the output position of the page buffer 18 is set. Next, step S6
In, the character code is retrieved from the document buffer 14,
Specify the character to output.

Next, in step S7, the pointer of the character data stored in the character data pointer 23 is initialized.

Next, in step S8, character part data is extracted. Next, in step S9, the part data in one bag is converted into center information and thickness information of the part. FIG. 6 is a diagram illustrating a method of obtaining center information and thickness information from outline data. As shown in FIG. 6, as a method of obtaining the center information and the thickness information from the outline data, for example, a tangent line of one minute unit of the outline of the outline data is obtained,
Establish a normal to the tangent. The center of the distance to the point where the normal line intersects with the contour line on the opposite side is the center point, and this coordinate is the center information. Further, the length from the fulcrum of the normal line to the intersection with the contour line on the opposite side becomes the thickness information. Therefore, the collection of these center points becomes the central information, and the collection of the distance from the fulcrum of the normal line to the intersection of the contour lines on the opposite side becomes the thickness information.

Next, in step S10, the thickness information obtained in step S9 is converted into speed information. Figure 7
FIG. 6 is a diagram showing a relationship between speed information and thickness information. Here, the thickness information is converted into speed information using the relationship shown in FIG. Next, the central information obtained in step S9 and the speed information obtained here are converted into vector information. The converted vector information is passed to the above paint system program.

Next, in step S11, the paint system program performs a predetermined modification process on the page buffer 18 based on the vector information, as in the case where the paint tool set in step S4 is used to move the page buffer 18. Output the dot data.

Next, in step S12, the pointer of the character data stored in the character data pointer 23 is updated.

Next, in step S13, it is confirmed whether or not the data is completed. If the data has been completed, the process proceeds to step S14, and if not completed, the process proceeds to step S8 and the subsequent processes are continued.

Next, in step S14, the pointer of the document buffer stored in the document buffer pointer 22 is updated.

Next, in step S15, it is confirmed whether or not the document to be output is completed. If it is completed, the process proceeds to step S16, and if it is not completed, the process proceeds to step S2 and the subsequent processes are continued.

Next, in step S16, the printer 16 prints the character which has been subjected to a predetermined modification process based on the dot data stored in the page buffer 18.

FIG. 8 is a diagram showing an example of characters output in the spray mode and the brush mode created by the above processing.

By the above processing, it is possible to create vector information using outline data having a small amount of information and perform a predetermined modification processing according to the vector information.

In the above embodiment, outline data has been described, but in the case of skeleton data, by using the center information and thickness information included in the skeleton data in steps S8 and S9 shown in FIG. It can be processed in the same manner.
