Abstract

PURPOSE: To simplify the processing related with a hatch precessing by rationally combining the producing of characters, the magnifying/reducing and the rotating of hatch data and logical operations. CONSTITUTION: Outline character data are transmitted from a host processing part 10 to an outline extension processing part. An outline extension pre- processing part 1 generates a hatch data transformation table based on the size of characters and the size of hatch data. Next, coordinates of the outline data are transformed in an outline extension coordinate transformation processing part 3 to transform the outline data into raster data. An outline internal hatch processing part 4 stores characters applied with a hatch processing in a character extension memory 5 while referring to the hatch transformation table and the hatch data by using the data processed in the outline extension coordinate transformation processing part 3. Then, a character data plotting part 23 executes the plotting display of the data of the character extension memory 5 to output it.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outline data hatching apparatus for performing a hatching process on outline data mainly used for character data.

[0002]

2. Description of the Related Art Characters used, for example, in headlines of newspapers and magazines often use a hatch pattern for the purpose of attracting or impacting the reader.

Conventionally, in order to use a hatch pattern for the characters of the headline, when the characters are hatched,
Characters are not treated as characters, but as a kind of figure. In general, when dealing with characters, many systems cannot display graphics, or the display of graphics is inconvenient, so hatching was performed when creating a headline or writing text. I could not confirm the letters. Therefore, when creating a document,
There is a demand for a function of displaying a hatched character as a character instead of a graphic.

Conventionally, when performing a hatching process on an outline character using an outline font, the outline character is expanded and then a logical operation is performed to perform the hatching process on the outline character.

Further, when it is necessary to enlarge / reduce or rotate the hatch data of a character in relation to the enlargement / reduction or rotation of the outline character itself to be hatched, the hatch data is enlarged. / After reducing or rotating, the hatching was done by logical operation.

The outline data storage unit 11 is a database that stores outline character data. The hatch data storage unit 12 is a database of hatch pattern data for hatch processing.

Character information such as headings, outline character data, and hatch pattern data are given from the upper processing unit 10, outline data storage unit 11 and hatch data storage unit 12 to an outline expansion preprocessing unit 13 of the outline expansion processing unit. To be

The outline expansion preprocessing unit 13 creates enlargement / reduction information based on character information such as a headline and outline character data, and supplies the hatch pattern data and its enlargement / reduction information to the hatch data enlargement / reduction unit 14. To do. The hatch data enlarging / reducing unit 14 enlarges or reduces the hatch pattern data according to the enlarging / reducing information, and supplies the hatch pattern drawing processing unit 16 with the hatch pattern data to perform a drawing process of the hatch pattern data, thereby creating a work memory for the hatch. It stores in 20.

Further, the outline expansion preprocessing unit 13 is
Character information such as headings and outline character data,
The outline character coordinate data is given to the outline expansion coordinate conversion unit 15 to convert the coordinates of the outline character data and expand it. The expanded outline character data is used for the outline internal filling part 17

[0014]

As described above, in the conventional outline character hatching processing, since the logical operation for the hatching processing is performed after the outline character is expanded, the processing takes a long time. Further, when the hatch pattern data is subjected to processing such as enlargement / reduction or rotation, the hatch data is enlarged / reduced or rotated in advance, and then the logical operation is performed, which further increases the processing time.

The present invention has been made in view of the above-mentioned circumstances, and simplifies the processing relating to the hatch processing by rationally combining character creation, hatch data enlargement / reduction, rotation, and logical operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an outline data hatch processing apparatus according to the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of an outline data hatch processing apparatus according to an embodiment of the present invention. In FIG. 1, the same parts as those in FIG. 7 are designated by the same reference numerals, and detailed description thereof will be omitted.

The outline data hatch processing apparatus of FIG. 1 comprises an outline expansion preprocessing unit 1, a hatch conversion table storage unit 2, an outline expansion coordinate conversion unit 3, an outline internal hatch processing unit 4, a character expansion memory 5, and an upper processing unit. It has an outline data storage unit 11, a hatch data storage unit 12, and a character data drawing unit 23.

Outline expansion preprocessing unit 1, hatch conversion table storage unit 2, outline expansion coordinate conversion unit 3, outline internal hatch processing unit 4, and character expansion memory 5.
Constitutes an outline expansion processing section. The parts configuring these outline expansion processing units are different from those in FIG. 7.

The upper processing unit 10, outline data storage unit 11, hatch data storage unit 12, and character data drawing unit 23 are the same as those in FIG. The outline expansion preprocessing unit 1 generates a hatch conversion table based on the character information provided from the upper processing unit 10 and the outline character data of the character corresponding to the character information extracted from the outline data storage unit 11.

When the outline character data is subjected to processing such as enlargement / reduction and rotation, a hatch conversion table corresponding to the processing such as enlargement / reduction and rotation is generated. The hatch conversion table storage unit 2 stores the hatch conversion table generated by the outline expansion preprocessing unit 1.

The outline expansion coordinate conversion unit 3 expands the outline character data corresponding to the character information extracted from the outline data storage unit 11 and converts the coordinates. The outline internal hatch processing unit 4 refers to the hatch conversion table stored in the hatch conversion table storage unit 2 and performs hatch processing on the outline character data expanded and coordinate-converted by the outline expansion coordinate conversion unit 3.

The character expansion memory 5 stores the outline character data that has been hatched by the outline internal hatch processing unit 4. The character data drawing unit 23 draws and outputs the character data using the outline character data stored in the character expansion memory 5.

That is, the outline character data is sent from the upper processing unit 10 to the outline expansion processing unit. The outline expansion preprocessing unit 1 generates a hatch data conversion table based on the character size and the hatch data size. Next, in order to convert the outline data into raster data, the outline expansion coordinate conversion processing unit 3 converts the coordinates of the outline data.

Using the data processed by the outline expanded coordinate conversion processing unit 3, the outline internal hatch processing unit 4 is referred to while referring to the hatch conversion table and the hatch data.
Stores the hatched characters in the character expansion memory 5.
The character data drawing unit 23 draws and displays the data in the character expansion memory 5 and outputs it.

Next, the operation of the outline data hatch processing apparatus having the configuration of FIG. 1 will be specifically described.
FIG. 2 is a flowchart of the outline expansion processing when there is no enlargement / reduction, rotation, etc.

First, when the outline expansion processing is started, the outline expansion coordinate conversion unit 3 creates an outline expansion coordinate conversion table (step S).
1). Based on the created outline expanded coordinate conversion table, the outline internal hatch processing unit 4 copies hatch data and performs hatch processing (step S2). The result is stored in the character expansion memory 5. The data drawing unit 23 draws characters using the data stored in the character expansion memory 5 (step S3).

In this case, as shown in FIG. 3, the outline character data has the coordinate information of the bending point, and the expanded coordinate conversion table is created based on this. The raster character of the hatched outline character data is generated using the expanded coordinate conversion table and the hatch data.

FIG. 4 is a flow chart of the outline expansion processing when there is enlargement / reduction and rotation. First, when the outline expansion processing is started, it is checked whether or not there is enlargement / reduction (step S11), and if there is no enlargement / reduction, the rotation angle is checked (step S1).
2). If it is determined in step S11 that there is enlargement / reduction, the scaling rate is calculated (step S1
3) and then to step S12.

Next, the coordinates in the X and Y directions are set according to the rotation angle and the scaling rate (step S1).
4) Then, the outline expansion preprocessing unit 1 creates a hatch data conversion table (step S15).

Then, the outline expanded coordinate conversion unit 3 creates an outline expanded coordinate conversion table (step S16), and based on the outline expanded coordinate conversion table and the hatch data conversion table.
The outline internal hatch processing unit 4 copies the hatch data and performs the hatch processing (step S17). The result is stored in the character expansion memory 5. The data drawing unit 23 draws characters using the data stored in the character expansion memory 5 (step S18).

If the hatch data has enlargement / reduction,
As shown in FIG. 5, an expanded coordinate conversion table is created based on the coordinate information of the bending points of the outline character data. Further, in the hatch data conversion table for enlargement / reduction, the source side coordinates are associated with the destination side coordinates for each of the X and Y coordinate axes. A raster character of the hatched outline character data is generated using the expanded coordinate conversion table, the hatch conversion table, and the hatch data.

When the hatch data is rotated, as shown in FIG. 6, an expanded coordinate conversion table is created based on the coordinate information of the bending points of the outline character data. In addition, the hatch data conversion table for rotation is X and Y.
3 is an inverse primary conversion table in which the coordinates on the source side are associated with the coordinates on the destination side for each coordinate axis. A raster character of the hatched outline character data is generated using the expanded coordinate conversion table, the hatch conversion table, and the hatch data.

In this way, since the hatching, which has conventionally been divided into the character creation and the logical operation, is combined into one processing, the hatching can be speeded up.
Further, even if the hatch data includes enlargement / reduction and rotation, it is performed as one process, so that the hatch process can be performed at high speed, and the processing time is significantly shortened.

The present invention is not limited to outline character data, and can be carried out in the same manner as described above when hatching other outline data.

[0040]

As described above, according to the present invention,
Generate a hatch conversion table for adding hatch to outline data based on specified outline data and hatch data, obtain outline coordinate data by expanding the outline data, and enter inside the outline coordinate data. , The hatch data is allotted by referring to the hatch conversion table and the hatch data, and the processing related to the hatch processing is simplified by rationally combining character creation, hatch data enlargement / reduction and rotation, and logical operation. Therefore, it is possible to provide a hatch processing device for outline data, which enables the hatch processing to be performed at high speed.
