FTGlyphCache::GetAdvanceX
Syntax
float FTGlyphCache::GetAdvanceX(FTFont *fontFace, GlyphCacheEntry *chLeft, utf32 chRight, int pointSize) const;Returns the horizontal advance in X direction that the 'pen' should be advanced after having rendered chLeft, and moving on to render chRight.
This function takes into account the kerning between characters, if present.
