Well, simply follow the documentation, i.e., set `pitch' to

  ((((w + 7) / 8) + 1) / 2) * 2

(but with some better C code :-) and use this value for creating the
bitmap.

 

Ok, I did change the value of pitch (6) and tried to draw `a', it is giving a wrong
glyph, then I changed the value to previous value(5), it drew a correct one[...]

* (gdb) p *bitmap
    $1 = {
      rows = 39,
      width = 39,
      pitch = 5,
      buffer = 0x5555557b3bf0 "",
      num_grays = 0,
      pixel_mode = 1 '\001',
      palette_mode = 0 '\000',
      palette = 0x0
    }
* I am attaching the glyph output of gfdriver, it completely satisfies these metrics.

Thank you
