Progressiv darstellbare Umrißschrift und Verfahren zum Erzeugen, Übertragen und Darstellen derselben

摘要

This invention relates to an outline font, and more particularly to a progressive renderable outline font and methods for transforming and rendering the same. Each character is stored in the format shown, comprising successive blocks of control point coordinates at cummulatively higher resoutions. Its purpose lies in supplying a progressively renderable Font which can be varied according to the quantity of the data composing the font. The Progressively Renderable Font has the function of controlling the display speed and the quality of the font. For example, if the hardware speed is relatively slow and a high quality font is not needed, only a part of the font data will be transmitted and displayed eg 1ST block of data 380. On the contrary, if the hardware speed is relatively fast and high quality font is needed, gradually increased data will be transmitted and displayed, eg blocks 382-392 in succession. Therefore, a font can be transmitted and displayed using minimal data without sacrificing quality. On the other hand, in case of the environment, all the data can be transmitted and displayed so that the quality of the font can be fully realized.
