Thank You Werner.
I tried as you said CBox to get the actual dimensions of the Glyph.
FT_Glyph_Get_CBox(glyph, *FT_GLYPH_BBOX_PIXELS*, &bbox);
fprintf( stderr, "bbox = [%ld %ld %ld %ld]\n",
bbox.xMin, bbox.yMin, bbox.xMax, bbox.yMax );
I got the follwoing for Glyph g and Glyph a respectivelly.
bbox = [0 3 12 14]
.......****.
.....*******
....****..*.
...***...**.

bbox = [0 2 10 14]

Where in in Set_Char_size i gave character size as 12.I thought i will be
getting the height of 12 pixels irrespective of the character.
Also,dont know why am i getting just a empty row at the end of glyph "A" and
one column for glyph "G" at the beginning?
Does it too corresponds to the glyph's bit map buffer ?
Could you please explain me if my understanding is wrong?
Thanks a lot...
