Constructor & Destructor Documentation

FTTextureFont() [1/2]

FTTextureFont::FTTextureFont

(

const char *

fontFilePath

)

Open and read a font file.

Sets Error flag.

Parameters

fontFilePath

font file path.

FTTextureFont() [2/2]

FTTextureFont::FTTextureFont	(	const unsigned char *	pBufferBytes,
		size_t	bufferSizeInBytes
	)

Open and read a font from a buffer in memory.

Sets Error flag. The buffer is owned by the client and is NOT copied by FTGL. The pointer must be valid while using FTGL.

Parameters

pBufferBytes	the in-memory buffer
bufferSizeInBytes	the length of the buffer in bytes

~FTTextureFont()

virtual FTTextureFont::~FTTextureFont ( )

virtual

Destructor.

Member Function Documentation

MakeGlyph()

virtual FTGlyph * FTTextureFont::MakeGlyph ( FT_GlyphSlot  slot )

protectedvirtual

Construct a glyph of the correct type.

Clients must override the function and return their specialised FTGlyph.

Parameters

slot	A FreeType glyph slot.

Returns

An FT****Glyph or null on failure.

Implements FTFont.
