Multi-language achieving method and system of POS machine

Abstract

The invention relates to a multi-language achieving method and system of a POS machine. The method comprises the steps that languages and related word stock resources are preliminarily set; characterstring codes are input; whether bidirectional sorting is needed or not is judged; if not, whether the font properties of ASCII character fields and non-ASCII character fields are consistent or not isjudged; if yes, conversion and deformation processing is conducted on the character string codes to obtain bitmap of the character string codes; gray scale setting is performed according to differentdevices; the bitmap of both the ASCII character fields and non-ASCII character fields is obtained, and output caching is performed according to the different devices; if not, the character string codes are converted into UINICODE codes; character strings needing bidirectional sorting are sorted, and character distinguishing is conducted on character strings which do not need bidirectional sortingand the sorted character strings. The problem is solved that Arabic, Khmer and other complex languages and a language dot matrix word stock cannot be achieved, and the method supports multiple languages.

Description

technical field [0001] The present invention relates to a POS machine, and more specifically refers to a multi-language implementation method and system for a POS machine. Background technique [0002] At present, financial POS often uses dot matrix fonts to achieve multilingual implementation. For example, each Chinese character is divided into 16×16 or 24×24 dots, and then the outline of the character is represented by the virtual and real of each dot. Due to the rules of concatenation of words and the rules of deformation of letters, Persian and Arabic cannot be processed with one letter as a unit, and need to be deformed according to the situation of back and front concatenation, which also leads to the use of dot matrix fonts in Arabic and Persian. would be very complex and display poorly. The writing direction of Arabic text is different from that of Chinese. It is written horizontally from right to left. Arabic books and notebooks are written on the right. When ASCII...

Problems solved by technology

However, for Khmer and other languages, the continuous writing deformation is complicated, such as figure 2 As shown, the combination is diverse, the position is strict, and the front and back characters are related. It is impossible to use the dot matrix font to realize the Khmer language

[0003] Moreover, the method of multilingual dot matrix fonts has the disadvantage of not being able to enlarge. Once enlarged, you will find jagged edges of the text, resulting in unsightly display; Arabic and other languages ​​with complex deformations are very complicated and inefficient. , its two-way sorting algorithm is complex and difficult to maintain; even Khmer and other languages ​​cannot be realized by using the dot matrix method because of the complexity of deformation and continuous writing; various shortcomings make the dot matrix font method not well support the realization of multi-languages, which affects the internationalization of the product. change

[0004] Therefore, it is necessary to design a multi-language implementation method for POS machines to solve complex and language dot matrix font library problems such as Arabic and Khmer, and to support multi-language
