Font selection
Most graphics in LilyPond are composed of characters of fonts. You can alter the characteristics of the font by setting certain grob properties. The mechanism that is used for this resembles LaTeX's New Font Selection Scheme. Within this scheme, a font is entirely characterized by its font name.
For each grob that uses fonts (in other words, each grob that supports
font-interface) a font-name must be selected before it can be
printed. The font name is selected by looking at a number of grob
properties:
font-family- A symbol indicating the general class of the typeface. Supported are
roman(Computer Modern),braces(for piano staff braces),music(the standard music font),dynamic(font for dynamic signs) andtypewriter font-shape- A symbol indicating the shape of the font, there are typically several
font shapes available for each font family. Choices are
italic,capsandupright font-series- A symbol indicating the series of the font. There are typically several
font series for each font family and shape. Choices are
mediumandbold. font-relative-size- A number indicating the size relative the standard size. For example,
with 20pt staff height, relative size -1 corresponds to 16pt staff
height, and relative size +1 corresponds to 23 pt staff height.
font-design-size- A number indicating the design size of the font.
This is a feature of the Computer Modern Font: each point size has a slightly different design. Smaller design sizes are relatively wider, which enhances readability. Scalable type faces such TrueType and Adobe Type1 usually come as "one design fits all sizes".
font-name- The name of the font, without the design size, e.g.
cmr,cmti, etc. Setting this overrides font-family, font-shape and font-series.
The font is selected by taking the first font that satisfies all
qualifiers specified. You can override any of these fields through
\override and \revert. The special value * matches
any value for that qualifier.
\property Lyrics.LyricText \override #'font-series = #'bold \property Lyrics.LyricText \override #'font-shape = #'*
There are also pre-cooked font selection qualifiers. These are selected
through the grob property font-style. For example, the style
finger selects family number and relative size -3.
Styles available include volta, finger, tuplet,
timesig, mmrest, script, large,
Large and dynamic.
The style sheets and tables for selecting fonts are located in
scm/font.scm. Refer to this file for more information.
BUGS
Relative size is not linked to any real size.
There is no mechanism to select magnification of particular fonts, meaning that you don't have access to continuously scaled fonts. You can scale the entire output, of course, see Output scaling.
There is no style sheet provided for other fonts besides the TeX family.
