A method and system for realizing multi-language of POS machine

Abstract

The present invention relates to a POS machine multi-language implementation method and system thereof, the method includes initially setting language and related font resources; inputting character string codes; judging whether bidirectional sorting is required; if not, judging ASCII character segments and non-ASCII characters Whether the font attributes of the segment are consistent; if they are consistent, convert and deform the string encoding to obtain the bitmap of the string encoding; set the gray scale according to different devices; obtain the bitmap of all ASCII character segments and non-ASCII character segments, Output cache according to different devices; if inconsistent, convert the string encoding to UINICODE code; sort the strings that require bidirectional sorting, and distinguish between the strings that do not need bidirectional sorting and the sorted strings. The invention solves the problem that Arabic, Khmer and other complex and language dot matrix fonts cannot be realized, and 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 languages ​​such as Khmer, 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
