Functions

Font(std::string fontPath, int iFlags = 0);

void LoadFontSize(int fontSize, int preloadAmount = 0, Dimension maxFontDims = {512, 512});

const GlyphData* GetGlyph(int fontSize, int ch);

std::map::iterator AddGlyph(int fontSize, int ch);

Font(std::string fontPath, int iFlags = 0);

Default constructor

Font(const Font& copy) = delete;

No copy constructor for now.

~Font();

Descturctor. Release all allocated memory & destroys SubFont objects.

void LoadFontSize(int fontSize, int preloadAmount = 0, Dimension<size_t> maxFontDims = {512, 512});

Loads a specific font size into memory. Allows to automatically load some glyphs.

bool IsSizeLoaded(int fontSize);

Checks whether the font size is already loaded.

void ReleaseFontSize(int fontSize);

Removes a font with a specific size from memory.

const int GetFontDpi() const;

Returns the DPI of the screen.

const GlyphData* GetGlyph(int fontSize, int ch);

Returns glyph data for a specific font size.

Texture* GetAtlasTexture(int fontSize);

Returns atlas texture for a specific font size.

const int GetLineHeight(int fontSize);

Returns new line height for a specific font size.

std::map<int, GlyphData>::iterator AddGlyph(int fontSize, int ch);

Adds a glyph (from the character) to a font of a specific size.

int m_iFlags;

Stores flags. Reserved.

std::string m_sFontPath;

Stores the path of the loaded file.

std::map<int, SubFont*> m_SubFonts;

It stores a data of specific sizes of a given font.

FT_Face m_Face;

FreeType variable that stores font Face.

FT_Bool m_HasKernings;

FreeType variable that describes whether the font supports kernings.

static FT_Library s_FTLibrary;

A handle to a FreeType library instance.

static bool s_FT2Initialized;
