Definition at line 46 of file FTGLPolygonFont.h.

## Constructor & Destructor Documentation

## ◆ FTPolygonFont() [1/2]

FTPolygonFont::FTPolygonFont | ( | const char * | fontFilePath | ) |

Open and read a font file.

Sets Error flag.

Parameters

  fontFilePath | font file path.

## ◆ FTPolygonFont() [2/2]

FTPolygonFont::FTPolygonFont | ( | 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

## ◆ ~FTPolygonFont()

FTPolygonFont::~FTPolygonFont | ( |  | ) |

Destructor.

## Member Function Documentation

## ◆ MakeGlyph()

virtual FTGlyph * FTPolygonFont::MakeGlyph | ( | FT_GlyphSlot | slot | ) |
| protected virtual

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.
