RE: Example Code

[Gaiser, Jason]

Well, what did you change!?!?
 
Also, I definitely agree that the current Freetype2 demo code is a bit
complicated.  I think it would be nice to have some basic code that doesn't
even involve graphics (perhaps just rendering the bitmaps to memory, or, as
I did once to test things, just construct strings and printf the bitmap to
the screen :) ).  Trying to understand both the freetype library AND the
demo code was a pain.
 
Just My Two Cents,
Jason
 
P.S. - Thanks for the great library guys!

Has anyone got any example code on how to use the Freetype 2 library. I know
that their are demos but this is too complicated for what I want to do.
 
All I want to do is to initialise the library, load a font and then create a
bitmap for a particular character.
 
Take a look at the following...
 

{
 FT_Library Library;

 if (FT_Init_FreeType(&Library) == 0)
 {
  FT_Face Face;
 
  if (FT_New_Face(Library,"arial.ttf",0,&Face) == 0)
  {
   if (FT_Set_Char_Size(Face,0,50*64,72,72) == 0)
   {
    FT_GlyphSlot Slot = Face->glyph;
    FT_UInt  GlyphIndex;
    int  nX = 100;
    int  nY = 100;
    unsigned char String[] = "TEST";
    int  nIndex = 0;
    
    while (String[nIndex])
    {
     if (FT_Load_Char(Face,String[nIndex],FT_LOAD_RENDER) == 0)
     {
      Display( Slot->bitmap,
        nX + Slot->bitmap_left ,
        nY + Slot->bitmap_top );
 
      nX += Slot->advance.x;
      nY += Slot->advance.y;
     }
     nIndex++;
    }
   }
  }
 }
 
This should generate a bitmap of a character but the bitmap size is zero
wide and has zero rows.
 
Could anyone tell me what I am doing wrong? Do I need to allocate the memory
for the bitmap myself or is this done by the freetype library.
 
Thanks in advance
