Detailed Description

Font manager The font manager manages CMaterial pointers through a list of CSmartPtr.

When the user asks for the texture font representing a character(font/size), it generates and stores this pointer in the list. If this character has already been generated, and lies in the list, it increments its reference count. If the memory used by generated textures exceeds the max memory, then the useless character/pointer is erased from the list. Max memory is set to 0 by default, so this value should be set to non-zero before generating textures to prevent immediate memory deletion.

void NL3D::CFontManager::computeString (  const ucstring &    s,
CFontGenerator *    fontGen,
const NLMISC::CRGBA &    color,
uint32    fontSize,
IDriver *    driver,
CComputedString &    output,
bool    keep800x600Ratio = true
) 
 

Same as computeString but works with a unicode string (ucstring).

void NL3D::CFontManager::computeString (  const std::string &    s,
CFontGenerator *    fontGen,
const NLMISC::CRGBA &    color,
uint32    fontSize,
IDriver *    driver,
CComputedString &    output,
bool    keep800x600Ratio = true
) 
 

Compute primitive blocks and materials of each character of the string.

Parameters:
s  string to compute
fontGen  font generator
color  primitive blocks color
fontSize  font size
desc  display descriptor (screen size, font ratio)
output  computed string
keep800x600Ratio  true if you want that CFontManager look at Driver window size, and resize fontSize so it keeps same size...
