Description

Method and system for generating Arabic character string resources and embedded equipment

Technical Field

The invention relates to an automobile electronic technology, in particular to a method and a system for generating an Arabic character string resource and an embedded device.

Background

At present, most electronic equipment is not friendly enough to support Arabic, and traditionally, the Arabic is displayed by using a language script scheme and a picture scheme. The language script scheme performs secondary operation during font rendering, and is mostly used in scenes with rich hardware resources, such as Personal Computers (PCs), smart phones and the like. For an embedded system with relatively limited hardware resources, the language script scheme has the defects of high requirements on the hardware resources, script development cost, difficulty in meeting the requirements of personalized display of a client and the like. The imaging scheme can fix all text strings into images, and can reduce the requirement on hardware resources to a certain extent, but on one hand, the direct conversion of character strings into images can cause the waste of storage space, especially when the number of Arabic texts is large; on the other hand, when the size of the text and the font is changed, the corresponding picture needs to be regenerated, which finally causes the maintenance cost of the software to be greatly increased.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention to those of ordinary skill in the art. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. Furthermore, it should be understood that the invention is not limited to the specific embodiments described. Rather, it is contemplated that the invention may be practiced with any combination of the following features and elements, whether or not they relate to different embodiments. Thus, the following aspects, features, embodiments and advantages are merely illustrative and should not be considered elements or limitations of the claims except where explicitly recited in a claim(s).

Fig. 1 illustrates a schematic block diagram of a generation system of an arabic string resource in accordance with one or more embodiments of the present invention. Referring to fig. 1, a generation system 100 of an arabic string resource includes one or more processors 110 and a computer-readable storage medium 120. The computer-readable storage medium 120 has stored thereon a plurality of instructions that can be executed by the processor 110 to implement the method 300 for generating an arabic string resource that downloads display resource encoding strings and arabic fonts to the embedded device 200 as will be described below. In one or more embodiments, computer-readable storage medium 120 may be a non-volatile computer-readable storage medium. The generation system 100 of the arabic string resource may include, for example, one or more of a personal computer, a notebook computer, a tablet computer, a server, and the like.

Fig. 2 illustrates a flow diagram of a method for generating an arabic string resource in accordance with one or more embodiments of the present invention. The generation method 300 of an arabic string resource may be executed on the generation system 100 of an arabic string resource, for example. Referring to fig. 2, the generation method 300 of the arabic character string resource includes the following steps:

step 310: acquiring a standard character encoding string of the Arabic character string;

step 320: converting the standard character code string into an expression character code string according to a preset conversion rule;

step 330: converting the expression character coding string into a display resource coding string according to a preset typesetting rule; and

step 340: and downloading the display resource coding string and the Arabic fonts to the embedded device.

In step 310, the generation system 100 of the arabic character string resource obtains the standard character encoding string of the arabic character string. The standard encoded string of characters may be, for example, a standard encoded string of characters that was entered by a developer via a keyboard or that has been stored in the computer readable storage medium 120.

In step 320, the Arabic character string resource generating system 100 converts the standard character encoding string into the representation character encoding string according to a predetermined conversion rule. Wherein the predetermined transformation rule comprises a position deformation rule and/or a connection deformation rule.

In one or more embodiments, the positional warping rule includes determining a representation character encoding for a character in the word based on a character preceding and/or a character succeeding the character. Specifically, according to the situation that the characters in the words belong to a word which is connected in front, connected behind, in the middle or independent, the standard character codes of the characters are replaced by the corresponding expression character codes. If the character before the character is in the front hyphen set, the character is determined to be a front hyphen, and the standard character code of the character is replaced by the corresponding front hyphen expression character code. If the character next to the character is in the postcursor character set, the character is determined to be postcursor, and the standard character code of the character is replaced by the corresponding postcursor expression character code. If the character is in the preceding hyphen set and the next character is in the succeeding hyphen set, the character is determined to be in the middle, and the standard character code of the character is replaced by the corresponding middle expression character code. And after the character is a single word, the standard character code of the character is the same as the expression character code. Fig. 3 illustrates an example of positional distortion of arabic in accordance with one or more embodiments of the present disclosure. Referring to fig. 3, if a character b following the character a is in the hyphen set, that is, if the character a is a hyphen, the character a is replaced with a character a'; the character b is replaced with a character b' if the preceding character a of the character b is in the hyphen set, i.e. the character b is a preceding hyphen.

In one or more embodiments, concatenating the distortion rules includes replacing the standard character encoding of two adjacent characters with a corresponding representation character encoding if the two characters conform to the hyphen rules of arabic. FIG. 4 illustrates an example of a connection variant of Arabic in accordance with one or more embodiments of the present invention. Referring to fig. 4, adjacent characters c and d conform to the hyphenation rule of arabic, and it is necessary to replace the two characters with one character e, and replace the standard character codes of the characters c and d with the expression character codes corresponding to the character e.

In step 330, the generating system 100 of the arabic character string resource predetermines the typesetting rules including reverse-ordering the representation character encoding strings. Since the arabic language is laid out from right to left, the encoded strings of the representation characters obtained in step 320 need to be inverted. That is, the first character encoding in the presentation character encoding string needs to be permuted to the last, the second character encoding to the second to last, and so on. If the expression character code string includes a non-arabic character, the encoding of the non-arabic character does not require a reverse operation.

In step 340, the generation system 100 of the arabic string resource downloads the display resource encoding string and the arabic font to the embedded device 200. The embedded device 200 may call an arabic font directly from the display resource encoding string to display the arabic character string.

In one or more embodiments, the generation system 100 of the arabic string resource may download only the arabic fonts corresponding to the rendering characters in the encoded string of rendering characters to the embedded device 200. In this way, the hardware resources required to store the arabic fonts can be reduced.

In one or more embodiments, the arabic fonts can include vector fonts and/or dot matrix fonts. Vector fonts describe the graphic information of each character by a curve equation (e.g., bezier N times), which can ensure arbitrary scaling without distortion. The dot matrix font is the graphic information describing each character through the dot matrix, the display speed is high, but the font needs to be regenerated aiming at the fonts with different sizes.

FIG. 5 illustrates a schematic block diagram of an embedded device in accordance with one or more embodiments of the invention. Referring to FIG. 5, the in-vehicle embedded device 200 includes one or more processors 210 and a computer-readable storage medium 220. The computer-readable storage medium 220 has stored thereon a plurality of instructions, the display resource encoding string generated by the generation method 300 of arabic string resources described above, and an arabic font, which the processor 210 can execute to invoke directly from the display resource encoding string the arabic font for displaying the arabic string. In one or more embodiments, the computer-readable storage medium 220 may be a non-volatile computer-readable storage medium. In one or more embodiments, the in-vehicle embedded device 200 may be an in-vehicle meter.

As described above, the generation system 100 and the generation method 300 of the arabic character string resource of the present invention convert the standard character encoding string of the arabic character string to be displayed into the expression character encoding string, and convert the expression character encoding string into the display resource encoding string according to the typesetting rule; the in-vehicle embedded device 200 may only need to store the display resource encoding string and the corresponding arabic font, and may directly call the arabic font according to the display resource encoding string to display the arabic character string. Therefore, the invention has the advantages of low software maintenance cost, low requirement on hardware resources of the vehicle-mounted embedded equipment 200 and the like.

Although the present invention has been described in connection with the preferred embodiments, it is not limited thereto. Various changes and modifications within the spirit and scope of the present invention will become apparent to those skilled in the art from this disclosure, and it is intended that the scope of the present invention be defined by the appended claims.
