getCoolTypeGlyphForChar

public int getCoolTypeGlyphForChar(int unicodeScalarValue)
                            throws InvalidFontException,
UnsupportedFontException

Description copied from class: FontData

Return the glyph used by CoolType for a character. This is slightly different from getGlyphForChar, and intend to be closer to the behavior of CoolType. The main use of this version is for other functions that emulate CoolType, such as the methods that compute metrics based on the charateristics of some glyphs. In most font types, this is the same as getGlyphForChar, so we provide a default implementation here.

Overrides:

getCoolTypeGlyphForChar in class FontData

Throws:

InvalidFontException
