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'.
