Member Function Documentation

uint8 * NL3D::CFontGenerator::getBitmap (  ucchar    c,
uint32    size,
uint32 &    width,
uint32 &    height,
uint32 &    pitch,
sint32 &    left,
sint32 &    top,
sint32 &    advx,
uint32 &    glyphIndex
) 
 

generate and return a bitmap.

Parameters:
c  the unicode char
size  size of the generated font in ??? format
width  width of the generated bitmap, this value is set by this function
height  height of the generated bitmap, this value is set by this function
pitch  pitch of the generated bitmap (+ or - the number of bytes per row), this value is set by this function

void NL3D::CFontGenerator::getKerning (  ucchar    left,
ucchar    right,
sint32 &    kernx

void NL3D::CFontGenerator::getSizes (  ucchar    c,
uint32    size,
uint32 &    width,
uint32 &    height
) 
 

returns the width and height of a character using a specific size and.

Warning:
this function is not very fast (but faster than getBitmap()) because it has to load the char before.
