mdbFontSize(5) The m17n Library mdbFontSize(5)NAME
mdbFontSize - Font Size
DESCRIPTION
In some case, a font contains incorrect information about its size (typically in the case of a hacked TrueType font), which results in a
bad text layout when such a font is used in combination with the other fonts. To overcome this problem, the m17n library loads information
about font-size adjustment from the m17n database by the tags <font, resize>. The data is loaded as a plist of this format.
FONT-SIZE-ADJUSTMENT ::= PER-FONT *
PER-FONT ::= '(' FONT-SPEC ADJUST-RATIO ')'
FONT-SPEC ::=
'(' [ FOUNDRY FAMILY
[ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
REGISTRY ')'
ADJUST-RATIO ::= INTEGER
FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
See m17nFont for the meaning of each property.
ADJUST-RATIO is an integer number specifying by percentage how much the font-size must be adjusted. For instance, this PER-FONT:
((devanagari-cdac) 150)
instructs the font handler of the m17n library to open a font of 1.5 times bigger than a requested size on opening a font whose registry is
'devanagari-cdac'.

mfontset_modify_entry(3m17n) The m17n Library mfontset_modify_entry(3m17n)NAME
mfontset_modify_entry - Modify the contents of a fontset.
SYNOPSIS
int mfontset_modify_entry (MFontset * fontset, MSymbol script, MSymbol language, MSymbol charset, MFont * spec, MSymbol layouter_name, int
how)
DESCRIPTION
Modify the contents of a fontset. The mfontset_modify_entry() function associates, in fontset fontset, a copy of font with the script /
language pair or with charset.
Each font in a fontset is associated with a particular script/language pair, with a particular charset, or with the symbol Mnil. The fonts
that are associated with the same item make a group.
If script is not Mnil, it must be a symbol identifying a script. In this case, language is either a symbol identifying a language or Mnil,
and font is associated with the script / language pair.
If charset is not Mnil, it must be a symbol representing a charset object. In this case, font is associated with that charset.
If both script and charset are not Mnil, two copies of font are created. Then one is associated with the script / language pair and the
other with that charset.
If both script and charset are Mnil, font is associated with Mnil. This kind of fonts are called fallback fonts.
The argument how specifies the priority of font. If how is positive, font has the highest priority in the group of fonts that are
associated with the same item. If how is negative, font has the lowest priority. If how is zero, font becomes the only available font for
the associated item; all the other fonts are removed from the group.
If layouter_name is not Mnil, it must be a symbol representing a mdbFLT (font layout table). In that case, if font is selected for drawing
an M-text, that font layout table is used to generate a glyph code sequence from a character sequence.
RETURN VALUE
If the operation was successful, mfontset_modify_entry() returns 0. Otherwise it returns -1 and assigns an error code to the external
variable merror_code.
