Public Member Functions

 FontFaceFreeType (Font *font)
 ~FontFaceFreeType () override
bool Load (const unsigned char *fontData, unsigned fontDataSize, float pointSize) override
 Load font face.
const FontGlyphGetGlyph (unsigned c) override
 Return pointer to the glyph structure corresponding to a character. Return null if glyph not found.
bool HasMutableGlyphs () const override
 Return if font face uses mutable glyphs.
- Public Member Functions inherited from Urho3D::FontFace
 FontFace (Font *font)
 ~FontFace () override
float GetKerning (unsigned c, unsigned d) const
 Return the kerning for a character and the next character.
bool IsDataLost () const
 Return true when one of the texture has a data loss.
float GetPointSize () const
 Return point size.
float GetRowHeight () const
 Return row height.
const Vector< SharedPtr< Texture2D > > & GetTextures () const
 Return textures.
- Public Member Functions inherited from Urho3D::RefCounted
 RefCounted ()
 Construct. Allocate the reference count structure and set an initial self weak reference.
virtual ~RefCounted ()
 Destruct. Mark as expired and also delete the reference count structure if no outside weak references exist.
 RefCounted (const RefCounted &rhs)=delete
 Prevent copy construction.
RefCountedoperator= (const RefCounted &rhs)=delete
 Prevent assignment.
void AddRef ()
 Increment reference count. Can also be called outside of a SharedPtr for traditional reference counting.
void ReleaseRef ()
 Decrement reference count and delete self if no more references. Can also be called outside of a SharedPtr for traditional reference counting.
int Refs () const
int WeakRefs () const
RefCountRefCountPtr ()
 Return pointer to the reference count structure.

Private Member Functions

bool SetupNextTexture (int textureWidth, int textureHeight)
 Setup next texture.
bool LoadCharGlyph (unsigned charCode, Image *image=nullptr)
 Load char glyph.
void BoxFilter (unsigned char *dest, size_t destSize, const unsigned char *src, size_t srcSize)
 Smooth one row of a horizontally oversampled glyph image.

Private Attributes

SharedPtr< FreeTypeLibrary > freeType_
 FreeType library.
