Re: [ft] Fw: [ft-devel] fitting a text

Ok found part of the problem: I had not multiplied the pixel height
with 64 for the FT_Set_Char_Size call. Now the resulting values make
more sense:

mine:

char 95 w×h = 6.0x1.0 ascender -1.0 bearingx -1.0 kern 0
char 103 w×h = 6.0x7.0 ascender 5.0 bearingx 0.0 kern 0
char 113 w×h = 6.0x6.0 ascender 5.0 bearingx 0.0 kern 0
char 116 w×h = 3.0x6.0 ascender 6.0 bearingx 0.0 kern 0
char 101 w×h = 5.0x5.0 ascender 5.0 bearingx 0.0 kern 0
char 115 w×h = 5.0x5.0 ascender 5.0 bearingx 0.0 kern 0
char 116 w×h = 3.0x6.0 ascender 6.0 bearingx 0.0 kern 0
char 49 w×h = 6.0x7.0 ascender 7.0 bearingx 2.0 kern 0
char 50 w×h = 6.0x7.0 ascender 7.0 bearingx 1.0 kern 0
char 51 w×h = 6.0x7.0 ascender 7.0 bearingx 0.0 kern 0
bitmap dimensions w×h = 52.0×9.0

yours:

char 95 wxh = 6x1 ascender -1 bearingx -1 kern 0
char 103 wxh = 6x7 ascender 5 bearingx 0 kern 0
char 113 wxh = 6x6 ascender 5 bearingx 0 kern 0
char 116 wxh = 3x6 ascender 6 bearingx 0 kern 0
char 101 wxh = 5x5 ascender 5 bearingx 0 kern 0
char 115 wxh = 5x5 ascender 5 bearingx 0 kern 0
char 116 wxh = 3x6 ascender 6 bearingx 0 kern 0
char 49 wxh = 6x7 ascender 7 bearingx 2 kern 0
char 50 wxh = 6x7 ascender 7 bearingx 1 kern 0
char 51 wxh = 6x7 ascender 7 bearingx 0 kern 0
bitmap dimensions wxh = 52x9

That's great!

Now with rendering enabled:

char 95 w×h = 6.0x1.0 ascender -1.0 bearingx -1.0 kern 0 bitmap: 7x1 left/top: 
-1,-1
char 103 w×h = 6.0x7.0 ascender 5.0 bearingx 0.0 kern 0 bitmap: 5x7 left/top: 
0,5
char 113 w×h = 6.0x6.0 ascender 5.0 bearingx 0.0 kern 0 bitmap: 5x6 left/top: 
0,5
char 116 w×h = 3.0x6.0 ascender 6.0 bearingx 0.0 kern 0 bitmap: 3x6 left/top: 
0,6
char 101 w×h = 5.0x5.0 ascender 5.0 bearingx 0.0 kern 0 bitmap: 5x5 left/top: 
0,5
char 115 w×h = 5.0x5.0 ascender 5.0 bearingx 0.0 kern 0 bitmap: 5x5 left/top: 
0,5
char 116 w×h = 3.0x6.0 ascender 6.0 bearingx 0.0 kern 0 bitmap: 3x6 left/top: 
0,6
char 49 w×h = 6.0x7.0 ascender 7.0 bearingx 2.0 kern 0 bitmap: 2x7 left/top: 2,7
char 50 w×h = 6.0x7.0 ascender 7.0 bearingx 1.0 kern 0 bitmap: 5x7 left/top: 1,7
char 51 w×h = 6.0x7.0 ascender 7.0 bearingx 0.0 kern 0 bitmap: 5x7 left/top: 0,7

Those bitmap sizes make sense. Only those left/top: -1,-1? and 0,5 for a bitmap 
of 5x7?
