OpenType features

Hieronder staan alle mogelijke waardes voor het veld "OpenType features":

Keyword	Name	Description
_none	all features disabled	Deactivate all OpenType features.
afrc	alternative fractions	Replace figures separated by a slash with an alternative form.
c2pc	petite capitals from capitals	Turn capital characters into petite capitals.
c2sc	small capitals from capitals.	Turn capital characters into small capitals.
calt	contextual alternates	Replace default glyphs with alternate forms which provide better joining behavior. Used in script typefaces which are designed to have some or all of their glyphs join.
case	case-sensitive forms	Shift accent marks upwards so that they work better with all-capital sequences or lining figures; also changes oldstyle figures to lining figures.
ccmp	glyph composition/decomposition	To minimize the number of glyph alternates, it is sometimes desired to decompose a character into two glyphs, or to compose two characters into a single glyph for better glyph processing. This feature permits such composition/decomposition.
clig	contextual ligatures	Replace a sequence of glyphs with a single glyph which is preferred for typographic purposes. Unlike other ligature features, clig specifies the context in which the ligature is recommended. This capability is important in some script designs and for swash ligatures.
cswh	contextual swash	Replace the default glyph with a corresponding swash glyph in a specified context.
dlig	discretionary ligatures	Replace a sequence of glyphs with a single glyph which is preferred for typographic purposes. dlig covers ligatures which may be used for special effects, at the user’s preference.
dnom	denominators	Replace figures which follow a slash with denominator figures.
falt	final glyph on line alternates	Replace line final glyphs with alternate forms specifically designed for this purpose (they would have less or more advance width as need may be), to help justification of text.
fina	final forms	Replace glyphs at the ends of words with alternate forms designed for this use. This is common in Latin connecting scripts, and required in various non-Latin scripts like Arabic.
frac	fractions	Replace figures separated by a slash with 'common' (diagonal) fractions.
hist	historical forms	Replace the default (current) forms with the historical alternates. Some letter forms were in common use in the past, but appear anachronistic today.
hlig	historical ligatures	Replace the default (current) ligatures with the historical alternates.
init	initial forms	Replace glyphs at the beginnings of words with alternate forms designed for this use. This is common in Latin connecting scripts, and required in various non-Latin scripts like Arabic.
isol	isolated forms	Replace the nominal form of glyphs with their isolated forms.
liga	standard ligatures	Replace a sequence of glyphs with a single glyph which is preferred for typographic purposes. liga covers ligatures which the designer/manufacturer judges should be used in normal conditions.
lnum	lining figures	Change figures from oldstyle to the default lining form.
locl	localized forms	Enable localized forms of glyphs to be substituted for default forms. This feature requires the script and language options.
medi	medial forms	Replace glyphs in the middle of words with alternate forms designed for this use. This is different from the default form, which is designed for stand-alone use. This is common in Latin connecting scripts, and required in various non-Latin scripts like Arabic.
mgrk	mathematical Greek	Replace standard typographic forms of Greek glyphs with corresponding forms commonly used in mathematical notation.
numr	numerators	Replace figures which precede a slash with numerator figures and replace the typographic slash with the fraction slash.
onum	oldstyle figures	Change figures from the default lining style to oldstyle form.
ordn	ordinals	Replace default alphabetic glyphs with the corresponding ordinal forms for use after figures; commonly also creates the Numero (U+2116) character.
ornm	ornaments	Replace the bullet character and ASCII characters with ornaments.
pcap	petite capitals	Turn lowercase characters into petite capitals, i.e. capital letters which are shorter than regular small caps.
pnum	proportional figures	Replace monospaced (tabular) figures with figures which have proportional widths.
salt	stylistic alternates	Replace the default forms with stylistic alternates. These alternates don’t always fit into a clear category like swash or historical.
sinf	scientific inferiors	Replace lining or oldstyle figures with inferior figures (smaller glyphs), primarily for chemical or mathematical notation).
smcp	small capitals	Turn lowercase characters into small capitals.
ss01...ss20	stylistic set 1-20	In addition to, or instead of, stylistic alternatives of individual glyphs (see salt feature), some fonts may contain sets of stylistic variant glyphs corresponding to portions of the character set, e.g. multiple variants for lowercase letters in a Latin font.
subs	subscript	Replace a default glyph with a subscript glyph.
sups	superscript	Replace lining or oldstyle figures with superior figures (primarily for footnote indication), and replace lowercase letters with superior letters (primarily for abbreviated French titles).
swsh	swash	Replace default glyphs with corresponding swash glyphs.
titl	titling	Replace default glyphs with corresponding forms designed for titling.
tnum	tabular figures	Replace proportional figures with monospaced (tabular) figures.
unic	unicase	Map upper- and lowercase letters to a mixed set of lowercase and small capital forms, resulting in a single case alphabet.
zero	slashed zero	Replace the glyph for the figure zero with an alternative form which uses a diagonal slash through the counter.
