GlyphSample Class Reference

class GlyphSample

Provides methods to map a TLanguage type to some pre-defined glyph samples. Samples are defined per writing script, e.g. specifying ELangFrench or ELangGerman will return the same set of samples. These samples are typically the tallest and 'deep'est characters w.r.t various scripts, useful for font rasterizers when calculating metrics.

const TInt KTLanguage2TScript

const TInt

KTLanguage2TScript

[private, static]

Maps TLanguage to TScript.

EScriptOther represents languages not yet supported in KTScript2GlyphSample. This array does not handle ELangNone and ELangMaximum to save storage space.

const TText *const KTScript2GlyphSample

const TText *const

KTScript2GlyphSample

[private, static]

Maps TScript to glyph samples.

The order of samples definition has to follow the script order in TScript.
