Detailed Description

Font class.

Loads font data and draws it. Is used by CText and CLabel, because, these are the only classes drawing text. At the moment there is only one font for all controls, but you can change between normal and italic styles, individually for any control.

Member Function Documentation

void sjgui::CFont::FontDraw ( int iX,

int iY,

const char * msg,

unsigned int uiLen,

float * fC4fv

)

Draw given text at given location with a given size and color.
This function could be called multiple times between DrawMsgBegin() and DrawMsgEnd()

float sjgui::CFont::GetFontScale ( ) [inline]

Scale of the font.
Required by CText only.

bool sjgui::CFont::LoadFont ( unsigned char * font_texture = NULL,

int font_width = 256,

int font_height = 256

) [static]

Load font from array of unsigned char values.
If font_texture is NULL, then default font is loaded. font_width and font_size denotes the size of the array. Array contains transparency map of the font. It should be square (at the moment) and contain 256 symbols. This is an example of the image:

There is a special program in the tools folder, which helps to create c array from a bmp image. There is also a good program to generate such font images, out there in the internet. Do not remember the name right now.
