[ft] Need help: newbee question

[varun shrivastava]

Hi,
    i am new to freetype, tried some test case but i am facing some problem in understanding.

After initializing library and face, i tried creating a bitmap for character 'C' and than setting size as
                     error = FT_Set_Char_Size(face, 0, 12*64, 300, 300);
which gave me an image like [1].

Than i changed the size to 16 as
                    error = FT_Set_Char_Size(face, 0, 16*64, 300, 300);
which gave me an image like [2].

Than i changed the dpi in the above call to 200.
                   error = FT_Set_Char_Size(face, 0, 16*64, 200, 200);
which gave me an image like [3].

If you look at [2] the drawing is slanted. I am drawing the bitmap on to a cairo surface and than dumping it into png file.
Which gets fixed if i change the 300dpi to 200dpi.

One more thing i did was to print the bitmap on screen (for all cases), which was properly printed (no slanting of character).

Can some one help me out to understand this.


Thanks
Varun
