X logical font description (XLFD) is a font standard used by the X Window System. It is intended to support: * unique, descriptive font names that support simple pattern matching * multiple font vendors, arbitrary character sets, and encodings * naming and instancing of scalable and polymorphic fonts * transformations and subsetting of fonts * independence of and operating or file system implementations * arbitrarily complex font matching or substitution * extensibility One prominent XLFD convention is to refer to individual fonts including any variations using their unique ''FontName''. It comprises a sequence of fourteen hyphen-prefixed, X-registered fields: #FOUNDRY: Type foundry - vendor or supplier of this font #FAMILY_NAME: Typeface family #WEIGHT_NAME: Weight of type #SLANT: Slant (upright, ''italic'', oblique, reverse italic, reverse oblique, or "other") #SETWIDTH_NAME: Proportionate width (e.g. normal, condensed, narrow, expanded/double-wide) #ADD_STYLE_NAME: Additional style (e.g. (Sans) Serif, Informal, Decorated) #PIXEL_SIZE: Size of characters, in pixels; 0 (Zero) means a scalable font #POINT_SIZE: Size of characters, in tenths of points #RESOLUTION_X: Horizontal resolution in dots per inch (DPI), for which the font was designed #RESOLUTION_Y: Vertical resolution, in DPI #SPACING: monospaced, proportional, or "character cell" #AVERAGE_WIDTH: Average width of characters of this font; 0 means scalable font #CHARSET_REGISTRY: Registry defining this #CHARSET_ENCODING: Registry's character encoding scheme for this set The following sample is for a 75-dpi, 12-point, Charter font: -bitstream-charter-medium-r-normal--12-120-75-75-p-68-iso8859-1(70 80_90 ) (which also tells the font source that the client is interested only in characters 65, 70, and 80-90.) == References == * * 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「X logical font description」の詳細全文を読む スポンサード リンク
