Detailed Description

Base class for all Fonts.

The class itself doesn't do anything usefull. It is more like interface. Anyone who need to access font returned from FontManager will have access to this interface. Fonts aren't thread safe and shloud be used only from one thread.

Member Function Documentation

virtual int Font::Ascent (   )  [pure virtual]

Get line height. The value is usefull if you want to render multiline text and need to know height of line. Returns: Height if line in font. Implemented in FontFTGL, and FontTTF.

void Font::cleanCache (   )  [virtual]

Clean the cache. Check the whole cache and delete members that weren't used for a long time. The exact behaviour is implementation dependent and cache even doesn't have to be implemented. Reimplemented in FontTTF. Definition at line 15 of file font.cpp.

virtual int Font::getTextWidth (  const std::string &  utf8str  )  [pure virtual]

Render some text in 3D.Get With of text in pixels. Get width of utf-8 encoded text. Returns: Width of text. Implemented in FontFTGL, and FontTTF.

virtual int Font::getWwidth (   )  [pure virtual]

Get width of W. W is usuallu the most width char in font so you may use this as aproximation. Returns: Width of W. Implemented in FontFTGL, and FontTTF.

virtual void Font::RenderUTF8 (  const std::string &  utf8str, float  x, float  y )  [pure virtual]

Render UTF-8 encoded string. Render text to specified position. First call may be slower if implementation use some cache for rendered fonts. Note: [0,0] is left bottom corner of screen. Parameters: utf8str  string that to be rendered x  x coodrinate if text y  y coodrinate if text Implemented in FontFTGL, and FontTTF.
