The Glyph Bitmap Distribution Format (BDF) by Adobe is a file format for storing bitmap fonts. The content takes the form of a text file intended to be human- and computer-readable. BDF is typically used in Unix X Window environments. It has largely been replaced by the PCF font format which is somewhat more efficient, and by scalable fonts such as OpenType and TrueType fonts. ==Overview== the current version of BDF is 2.2. No future revisions are anticipated. Earlier versions were referred to as the Character Bitmap Distribution Format. The X Window Consortium adopted BDF 2.1 as a standard for X Window screen fonts, but has largely moved to other standards such as PCF, Opentype, and Truetype. Version 2.2 added support for non-Western writing. For example, glyphs in a BDF 2.2 font definition can specify rendering from top-to-bottom rather than simply left-to-right. A BDF font file contains three sections: #a global section that applies to all glyphs in a font; #a section with a separate entry for each glyph; and #the ENDFONT statement. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Glyph Bitmap Distribution Format」の詳細全文を読む スポンサード リンク
