Abstract

PURPOSE:To obtain bit map data which still have good quality by reducing data of a KANJI(Chinese character) outline font. CONSTITUTION:A stroke information storage part 1 is stored with a group of stroke information consisting of stroke identifiers showing respective standard shapes of strokes of KANJI, relative sizes of the standard shapes on the KANJI, and the relative coordinates of the strokes on the KANJI. An outline information storage part 2 is stored with a group of coordinates of definition points determining the outlines of the standard shapes of the strokes indicated by the stroke identifiers. At a data input part 3, the character code, font, and size of object KANJI are determined. A stroke information retrieval part 4 obtains a stroke information group on the basis of the character code. An outline information retrieval part 5 retrieves the outline information storage part 2 on the basis of the font and stroke identifier as keys to obtain the outlines of the strokes. A bit map generation part 5 determines the size and position according to the character size, relative size, and relative coordinates to compose KANJI, thereby obtaining bit map data filling the inside.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a font data creation / expansion method, and more particularly to a font data creation / expansion method for obtaining bitmap data of a kanji from an input kanji typeface, size and character code.

[0002]

2. Description of the Related Art In recent years, the resolution of display-type devices has been increasing more and more, and due to the popularization of desktop publishing (DTP), which is one of the simple publications, there is a demand for fonts capable of high-quality output at any size. Is increasing.

Fonts are data for displaying characters and are roughly classified into bitmap fonts and vector fonts. Bitmap fonts define a character image as a set of dots, but the quality of the font is extremely degraded by scaling, so it is not suitable for use in high-resolution devices. On the other hand, since the vector font defines a character image by a sequence of dots, the amount of data increases with respect to the bitmap font, but the quality does not deteriorate due to scaling.

The outline font is a kind of vector font, and a curve connecting the point sequences from each partial point sequence is generated, the outline of the character is determined by the composition, and the inside is filled to obtain the image. Outline fonts are device-independent, and are capable of producing high-quality images of any size for any resolution, but on the other hand, they have a huge amount of data and require complicated processing.

[0005]

While the above-mentioned conventional outline font enables high-quality output, the amount of data in the font is enormous, and it is necessary to expand each character into a bitmap, thus improving processing efficiency. Is decreasing.
In addition, especially for a Kanji font, many points are required to define an image and the number of characters is very large. Therefore, in order to use this, a large-capacity storage device and a high-speed processor configuration are required. There is a problem.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
The embodiment of FIG. 1 comprises a stroke information storage unit 1, an outline information storage unit 2, a data input unit 3, a stroke information search unit 4, an outline information search unit 5, and a bitmap generation unit 6.

The stroke information storage unit 1 stores stroke information for each of a plurality of Chinese characters. FIG. 2 is a block diagram showing the content of stroke information stored in the stroke information storage unit 1. The stroke information for each Chinese character is a character code for the Chinese character, the number of strokes of the Chinese character, the stroke identifier for each stroke, and the relative size. , And individual stroke information composed of relative coordinates. The kanji stroke count is the number of dots and strokes that make up the kanji. The stroke identifier is a code for identifying the basic stroke with the standard form of the dots and strokes forming the Chinese character as the basic stroke. The relative size indicates the size of the stroke on the kanji relative to the basic stroke, and the relative coordinate indicates the position of the stroke on the kanji area.

The outline information storage unit 2 stores, as outline information, a plurality of definition points that determine an outline for each of a plurality of basic strokes for each typeface and their coordinate groups. FIG. 3 is a diagram showing a configuration of outline information stored in the outline information storage unit 2. By connecting these coordinate points, a basic stroke point or a stroke image is generated.

The operation of the embodiment of FIG. 1 having the above configuration will be described. The data input unit 3 determines a character code, a typeface, and a size of a Chinese character according to data input from the outside. The stroke information retrieval unit 4 is the data input unit 3
The stroke information storage unit 1 is searched by using the character code obtained from the above as a key to obtain stroke information including stroke identifiers, relative sizes, and relative coordinates of all strokes of the target Chinese character. The outline information search unit 5 acquires the definition point coordinates of all the basic strokes of the specified Chinese character from the outline information storage unit 2 using the typeface determined by the data input unit 3 and the stroke identifier acquired by the stroke information search unit 4 as keys. To do.

FIG. 4 is a flow chart of the process of the bitmap generation unit 6. The process of the bitmap generation unit 6 will be described with reference to the flow chart of FIG. 4. The bitmap generation unit 6 shows the number of strokes obtained from the stroke information. It is checked whether or not all strokes have been processed (step 101), and when the stroke count processing has been completed, the target kanji bitmap is determined. If the stroke count processing has not been completed, the outline definition point coordinate group obtained from the next stroke identifier retrieved by the outline information storage unit 5 is extracted (step 102). Next, according to the size of the Chinese character obtained by the data input unit 3, the coordinates of the defined point coordinate group obtained in step 102 are
The image is enlarged or reduced with respect to the origin of the image obtained from these coordinates (step 103). By this processing, the coordinates of the point of the designated Chinese character or the defining point that determines the outline of the image are obtained. Next, offset processing is performed on the coordinates of these definition points using the relative coordinates obtained from the stroke information (step 104). By this processing, the definition point that determines the outline can be moved to the regular position of the stroke of the Chinese character. Next, the coordinates of these definition points are connected to create an outline, and dots are filled in the outline to obtain bitmap data (step 105). The bit map data obtained here and the bit map data obtained in the preceding stroke are combined (step 106). When the processing of steps 101 to 106 is performed for all the character strokes, the bitmap data of the entire kanji is obtained from step 106.

[0013]

As described above, the present invention obtains definition points of stroke outlines according to the typeface and size of designated Kanji characters from the standard forms of strokes constituting Kanji, and fills those outlines. Combining bitmap data,
Since the target kanji bitmap data is obtained, there is an effect that high quality kanji bitmap data can be created with a smaller data amount than the conventional kanji outline font data amount.
