Member Function Documentation

float FontGl::getHeight (  float  zoom  )  [virtual]
 

Returns the height of the font at zoom factor zoom.

Implements Font.

Definition at line 142 of file FontGl.cpp.

float FontGl::getWidth (  const string &  data,
float  zoom
)  [virtual]
 

Returns the width of a string data at zoom factor zoom.

Implements Font.

Definition at line 130 of file FontGl.cpp.

void FontGl::loadFontGfx (  const string &  fileName,
const string &  fontDefinition = "!\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~"
) 
 

Loads a SFont file.

fileName is the name (may include path) of the SFont.

fontDefinition is a string containing the letters in the SFont.

Definition at line 48 of file FontGl.cpp.

void FontGl::prepareDrawing (   )  [virtual]
 

Prepares the display for drawing of letters, you may have to prepare the display for drawing other things after this cal.

Implements Font.

Definition at line 23 of file FontGl.cpp.

void FontGl::printChar (  const char  data,
float  x,
float  y,
float  zoom
)  [virtual]
 

Writes a character data at x,y with the given zoom factor. prepareDrawing must have been called first.

Implements Font.

Definition at line 85 of file FontGl.cpp.

void FontGl::printString (  const string &  value,
float  x,
float  y,
float  zoom
)  [virtual]
 

Writes a string value at x,y with the given zoom factor. prepareDrawing must have been called first.

Implements Font.

Definition at line 114 of file FontGl.cpp.

void FontGl::setScreenSize (  float  virtualWidth,
float  virtualHeight,
int  displayWidth,
int  displayHeight
) 
 

Sets display size hints for the font.

the virtualWidth and virtualHeight defines the range of coordinates regardless of actual display size, coordinates and font size will be scaled to fit the actual display size.

displayWidth and displayHeight are the actual display size.

Definition at line 76 of file FontGl.cpp.

void FontGl::unloadFontGfx (   ) 
 

Frees the OpenGL texture memory used by the font, call this before reloading the font.

Definition at line 147 of file FontGl.cpp.
