(

const char *

fontFilePath

)

Attach auxilliary file to font e.g font metrics.

void makVrv::DtFont::setFreeTypeLoadFlags

(

unsigned int

flags

)

Set the FreeType load flags.

bool makVrv::DtFont::setCharacterMap

(

unsigned int

encoding

)

Set the FreeType characte encoding map.

(

)

const

Get the number of charater maps.

const DtFreeTypeFace& makVrv::DtFont::freeTypeFace

(

)

const

bool makVrv::DtFont::setFaceSize

(

const unsigned int

size

)

unsigned int makVrv::DtFont::faceSize

const

virtual float makVrv::DtFont::lineHeight ( ) const

virtual

Implements makVrv::DtFontInterface.

virtual DtBoundingBox makVrv::DtFont::calculateBoundingBox ( const DtPen &  pen, const DtUnicode &  string, unsigned int  pos = 0, int  len = -1  )

virtual

Calculate the bounding box for a string.

Implements makVrv::DtFontInterface.

virtual Dt2dPoint makVrv::DtFont::calculateGlyphSize ( const DtPen &  pen, const DtUnicode &  string, unsigned int  pos = 0, int  len = -1  )

virtual

Calculate the bounding box for a string.

Implements makVrv::DtFontInterface.

float makVrv::DtFont::calculateAdvance	(	const DtPen &	pen,
		const DtUnicode &	string,
		unsigned int	pos = 0,
		int	len = -1
	)

void makVrv::DtFont::releaseResources

(

)

bool makVrv::DtFont::isValid ( ) const

virtual

Returns true if this font is valid (has a character map)

Implements makVrv::DtFontInterface.

bool makVrv::DtFont::checkError

(

)

const

Asks the private implementation to see if there is an error with the font.

DtGlyph* makVrv::DtFont::findOrLoadGlyphForRendering	(	DtGlyphRenderer &	renderer,
		const unsigned int	characterCode,
		bool	characterCodeIsIndex = false
	)

Returns the glyph to render given the character code. If characterCodeIsIndex is true then the character code given is an index into the font, not the character code itself.

DtGlyph* makVrv::DtFont::findOrLoadGlyph

(

const unsigned int

chr

)

Load the glyph, or return null if the glyph is not loaded.

unsigned int makVrv::DtFont::indexInFont

(

const unsigned int

characterCode

)

const

Returns the absolute index of the font in the font set given the font character. Internally used to map character font to its index.

Dt2dPoint makVrv::DtFont::calculateKerning	(	unsigned int	index1,
		unsigned int	index2
