Re: [Freetype] Windows code displaying garbage - any help?

[Greg Inman]

To check the Freetype bitmap it might help to print it to standard output.
Then you can check it pixel by pixel.  For a pixel that is background use
'O' and for a pixel that is set use 'X'.  At the end of the scan line start
a new line.

You may be able then to see how your interpretation of the Freetype bmp is
flawed.
