Detailed Description

Implementation of Font using FTGL.

This was first try of font. The implementation is without any kind of cache. Don't expect high performance, but it works.

Note:

Currently the implementation isn't complete and isn't woking.

Constructor & Destructor Documentation

FontFTGL::FontFTGL (  const char *  file, int  ptsize )

Construct font. Program is killed if contruction fails. Parameters: file  Path with file. locateFile isn't used inside. ptsize  Size of font. Definition at line 15 of file font_ftgl.cpp. References DIE(), LOGE, and mFont. Here is the call graph for this function:

FontFTGL::~FontFTGL (   )  [virtual]

Destroy allocated font. Definition at line 28 of file font_ftgl.cpp. References mFont.

Member Function Documentation

int FontFTGL::Ascent (   )  [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. Implements Font. Definition at line 52 of file font_ftgl.cpp. References assertL, and mFont.

virtual int FontFTGL::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. Implements Font.

virtual int FontFTGL::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. Implements Font.

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

Render utf-8 encoded text. This function must be called in 2D opengl mode. Parameters: utf8str  string to render x  x coordinate of text y  y cooridnate of text Implements Font. Definition at line 37 of file font_ftgl.cpp. References assertL, mFont, TIN, and utf8tows(). Here is the call graph for this function:
