Abstract
The invention relates to a graphics primitive input method and a keyboard for Dongba characters, and belongs to the field of computer word-processing. The input method has the following steps: firstly, the four primary structures of Dongba characters: a single structure, an up-and-down structure, a left-and-right structure and an encircled structure are coarsely coded into d, s, z and b respectively; secondly, Dongba characters are decomposed into the following graphics primitives: a dot, a straight line, a circle, a circular curve, a left diagonal, a right diagonal, a vertical line, a vertical curve, an elliptic curve and a rectangle, the second coding is carried out and at the same time the appearing numbers of the graphics primitives are coded; and then, the coarse coding and the secondary coding of each character are combined in sequence, thereby obtaining the graphics primitive input method of Dongba characters. Tests of the method show the keycode rate is far lower than that of a spelling input method of Dongba characters. The method is characterized in that the method is simple and easy to learn, thereby enabling persons who can't read and write the Dongba characters to input the Dongba characters into computers, and facilitating the promotion and the spread of the Dongba characters.
Description
Technical field
The invention belongs to the minority language field of information processing.
Background technology
It is Yi Zhi Naxi language that dto-mba writing belongs to Balti, has 2120 pictographs, is unique being handed down in world's ancient writing, and a kind of literal that also lives so far, for the research world literal developing history important value is arranged.Domestic and international research for Dongba character starts from the beginning of the eighties of last century, and the U.S., Japan, a lot of colleges and universities in Europe and research institution have all carried out deep research to Dongba character now.Traditional Dongba character information processing technology adopts manual modes such as manual drawing, scanning, plate-making; Because the Dongba character font is extremely complicated; For example there is multiple ways of writing in the literal such as
of Dongba character; Grasp writing of 2120 everyday characters, need the time in 10 years at least.This manual treatment effeciency is low, is not suitable for the needs of modern text information processing, needs a kind of method that can export Dongba character accurately.We have developed the Dongba character spelling input method, need the user to grasp the pronunciation of Dongba character by sound output Dongba character, and this can't carry out the computing machine typing for the people who is ignorant of pronunciation.To this situation, the present invention has designed DongBa character primitive input method and keyboard.
Summary of the invention
The common structure of Dongba character has: independent body structure, up-down structure, left and right sides structure, these four kinds of primary structures of investing mechanism.Which alone structure like?
vertical structures such as?
etc.; around structures such as?
, etc.; surrounding structures?
and so on.
At first we encode to the Dongba character structure, and the volume of independent body structure is d, up-down structure be written as s; Left and right sides structure be written as z; Investing mechanism be written as b, so just Dongba character has been carried out one-level and has slightly encoded, next to carry out secondary and carefully encode four kinds of structures of Dongba character.
Dongba character is a kind of pictograph, differently with Chinese character is that it does not have the notion of radical, therefore can not equally propose to encode and keyboard map according to radical according to the Five-stroke Method.Generally come unique figure of sign in " computer graphics " and " tactic pattern identification " with a plurality of orderly pels.Dongba character exactly is exactly a kind of pictograph, and form of presentation that also can reference pattern carries out pel to Dongba character and extracts, and then pel is carried out effective input method coding and computer keyboard mapping.
The common fundamental element that is used for describing figure is pel just, a bit, straight line, circle, circular curve, left oblique line, right oblique line, vertical line, vertical curve, elliptic curve, these several kinds of element figures of rectangle.These several kinds of pels are encoded, and coding is shown in table 1 DongBa character primitive coding schedule in detail.
Dongba character is owing to be to contain numeral in the structure of a lot of literal of a kind of pictograph, and this Chinese character and other minority languages have distinct difference.Like the quantity of dice
mid point, the quantity of burning
vertical curve, the quantity of treasure
circle etc., these all need carry out the coding of quantity.To pel repeat quantity occurs and carried out respective coding, y (), e (two), s (three), f (four), w (five), l (six), q (seven), b (eight), j (nine), d (many).
Table 1 Dongba character secondary coding schedule
| Pel | The point | Straight line | Circle | Circular curve | Left side oblique line |
| Coding | a | b | c | f | g |
| Pel | Right oblique line | Vertical line | Vertical curve | Elliptic curve | Rectangle |
| Coding | h | i | g | k | l |
For Dongba character we take from top to bottom, from left to right, coded sequence from outside to inside, according to the coding rule of discussing among the present invention making code table of encoding.After according to the foregoing invention content Dongba character having been carried out structure and figure primitive encoding, also need carry out computer keyboard mapping to it, the mapping of detailed calculated keyboard is as shown in table 2.Part Dongba character encoding of graphs is following:
