Constructor & Destructor Documentation

◆ FTTextureFont() [1/2]

FTTextureFont::FTTextureFont ( const char *  fontFilePath)

Open and read a font file.

Sets Error flag.

Parameters
fontFilePathfont 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
pBufferBytesthe in-memory buffer
bufferSizeInBytesthe 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
slotA FreeType glyph slot.
Returns
An FT****Glyph or null on failure.

Implements FTFont.
