If consumer electronic products are to be marketed all over the world today, the bottom line requirement is to have information displayed in a local language. However, in addition to the requirement of displaying internal fonts on screen, the layout of various languages has to be dealt with. To handle complex language layout, for example, Arabic or Hindi, a professional linguistic is needed. The Arphic Layout Engine is a multi-language text layout specialized program, providing multi-language text layout functionalities for embedded systems, using the most effective methods to solve the difficult problems of multi-language display for consumer electronic products.
Why the Arphic Layout Engine?
Hindi, Bengali, Tamil and Sinhala and other languages arranged left-to-right are formed using an extremely complex method involving putting consonants and vowels together. Ordinary font systems cannot handle them. Arabic, Farsi and Hebrew and other right-to-left languages require font substitutions and sometimes they need bi-directional layout with English and other right-to-left languages. Based on our professional font design capabilities, rich multi-language font design experiences and state-of-the-art software development technologies, we have overcome complex text combination rules and developed the Arphic Layout Engine to support the bi-directional text layout of the aforementioned complex languages in addition to English, Chinese, Japanese, etc.
The Arphic Layout Engine is a small, fast, and powerful program, it can be applied as the interface text and information display of various handheld devices, for example: cell phones, MP3 players and media players. In addition, with regards to different digital home appliances, for example STB, DTV, and LCDs on industrial machines, etc; it can be applied as interface text and information display as well.
