{FreeType\_\acro{MF}\_Module: A module for using \MF\ directly inside FreeType's rasterizer} {Jaeyoung Choi} {\MF{} is a font description language which generates bitmap fonts for use by the \TeX\ system, printer drivers, and related programs. One advantage of \MF{} over outline fonts is its capability to produce various font styles by changing parameter values defined in its font specification file. Another major advantage of using \MF{} is that it produces various font styles like bold, italic, and bold-italic from one source file, unlike outline fonts, which require development of a separate font file for each style in one font family. These advantages can be applied to design \CJK{} (Chinese-Japanese-Korean) fonts, which require significant time and cost because of the large number of characters used in these scripts. However, in order to use \MF{} in current font systems, users need to convert its bitmaps into a corresponding outline font. Furthermore, font rendering engines like FreeType do not support \MF{}. In this paper, an MF Helping Module for FreeType rasterizer is proposed. This `FreeType\_MF\_Module' enables direct usage of \MF{} just like any other outline and bitmap font support in FreeType rasterizer. Users of \MF{} don't need to pre-convert \MF{} into its corresponding outline font as the module automatically does this. Furthermore, the module allows users to easily and directly generate various font styles from \MF{} by changing parameter values. }
