Info

notes below. The notation for a is the full font name, which must be quoted since it may contain any character, including spaces and punctuation, and also must be enclosed in "local(" and ")". Example(s): src: url("http://foo/bar") a full URI and no information about the font format(s) available there src: local("BT Century 751 No. 2 Semi Bold Italic") references a particular face of a locally installed font src: url("../fonts/bar") format("truedoc-pfr") a partial URI which has a font available in TrueDoc format src: url("http://cgi-bin/bar?stuff") format("opentype", "intellifont") a full URI, in this case to a script, which can generate two different formats - OpenType and Intellifont src: local("T-26 Typeka Mix"), url("http://site/magda-extra") format("type-1") two alternatives are given, firstly a locally installed font and secondly a downloadable font available in Type 1 format. Access to locally installed fonts is via the . The font face name is not truly unique, nor is it truly platform or font format independent, but at the moment it is the best way to identify locally installed font data. The use of the font face name can be made more accurate by providing an indication of the glyph complement required. This may be done by indicating the range of ISO 10646 character positions for which the font provides some glyphs (see ’unicode-range’). 15.3.6 Descriptors for Matching: ’panose-1’, ’stemv’, ’stemh’, ’slope’, ’cap-height’, ’x-height’, ’ascent’, and ’descent’ These descriptors are optional for a <strong>CSS2</strong> definition, but may be used if intelligent font matching or font size adjustment is desired by the author. ’panose-1’ (Descriptor) Value: []{10} Initial: 0 0 0 0 0 0 0 0 0 0 Media: visual This is the descriptor for the Panose-1 number [p. 230] and consists of ten decimal integers, separated by whitespace [p. 37] . A comma-separated list is not permitted for this descriptor, because the Panose-1 system can indicate that a range of values are matched. The initial value is zero, which means "any", for each PANOSE digit; all fonts will match the Panose number if this value is used. Use of the Panose-1 descriptor is strongly recommended for latin fonts. For further details, see Appendix C [p. 299] . 220
’stemv’ (Descriptor) Value: Initial: undefined Media: visual This is the descriptor for the vertical stem width [p. 231] of the font. If the value is undefined, the descriptor is not used for matching. If this descriptor is used, the ’units-per-em’ [p. 218] descriptor must also be used. ’stemh’ (Descriptor) Value: Initial: undefined Media: visual This is the descriptor for the horizontal stem width [p. 228] of the font. If the value is undefined, the descriptor is not used for matching. If this descriptor is used, the ’units-per-em’ [p. 218] descriptor must also be used. ’slope’ (Descriptor) Value: Initial: 0 Media: visual This is the descriptor for the vertical stroke angle [p. 231] of the font. ’cap-height’ (Descriptor) Value: Initial: undefined Media: visual This is the descriptor for the number of the height of uppercase glyphs [p. 228] of the font. If the value is undefined, the descriptor is not used for matching. If this descriptor is used, the ’units-per-em’ [p. 218] descriptor must also be used. ’x-height’ (Descriptor) Value: Initial: undefined Media: visual This is the descriptor for the height of lowercase glyphs [p. 228] of the font. If the value is undefined, the descriptor is not used for matching. If this descriptor is used, the ’units-per-em’ [p. 218] descriptor must also be used. This descriptor can be very useful when using the ’font-size-adjust’ property, because computation of the z value of candidate fonts requires both the font size and the x-height; it is therefore recommended to include this descriptor. 221
