VFlib 3 . 5 . 0 — a general font library that supports multiple

VFlib is a font library written in C providing several functions to obtain bitmaps of characters (i.e., a rasterizer). VFlib hides the font format of font files and provides a unified API for all supported font formats. Thus, programmers of application software need not worry about font file formats and any software using VFlib can support various font file formats immediately. In addition to this, when a new font format is supported by VFlib, application software need not be modified to use such new fonts. VFlib has been developed for not only Latin fonts but also Asian scripts such as Chinese, Japanese, and Korean. Since it is designed as a general font module, it can be used in DVI drivers for TEX and LTEX. In this paper, we explain the API of VFlib, a font database file called vflibcap, and the internal structure of VFlib.
