RE: [ft-devel] freetype2 question

Hi,

 

> FT_Set_Char_Size(ft_face

> FTC_ImageCache_LookupScaler(

 

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,

 

Jon

Subject: [ft-devel] freetype2 question

Hello,

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)

 if(token==character)

  draw_character(x,y,character);

}
 

- 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

"Printing

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.
