You can't use these 2 functions together.  If you use FTC_ImageCache_LookupScaler, then the Freetype cache API will handle setting the size on the font.  It does this with the scaler parameter you pass to FTC_ImageCache_LookupScaler.  So there is no need to call FT_Set_Char_Size - instead you should just change the scaler parameter to FTC_ImageCache_LookupScaler.
Kind regards,

Subject: [ft-devel] freetype2 question

This is an explanation of my problem
the text that I parse is :
"[tagTITLE] Printing [endtagTITLE]
how to make printing."
- It consisting of 2 lines: the first is a Title means double sized
the second line is a simple text
- The algorthime is
while (getNextToken)
 if (tken==tagTITLE)
      FT_Set_Char_Size(ft_face, 64*
     24, 64 *24 ,600,600)
 if (tken==endtagTITLE)
      FT_Set_Char_Size(ft_face, 64*
     12, 64 *12 ,600,600)
- in the function draw_character , I call the function
FTC_ImageCache_LookupScaler(image_cache, &scaler, ft_load_flags, glyph_index, &CacheGlyph, NULL )
-The scaler is always the following:
scaler.width =12*64;
 scaler.height = 12*64;
 scaler.pixel = 0;
 scaler.x_res = 600;
 scaler.y_res = 600;
 scaler.face_id = face_id;
- The result is
how to make printing"
- The second 't' and "printing" are so big beaucause they are cached with the size 24.
I don't comprehend why some character in the second lin are with a 24 size (t,P,r,i,n,t,i,n,g)
Please If you can help me.
