can you give me hand on this? and is there a chance to have antialiasing support and make the BMP file only 4 bit per pixel or 8 bit or even have option to select and at the same time have Auto sizing and Constant size... if you could put some comment in your code then I would learn it and can modify it myself.
and will it automatically support unicode or have to be adjusted?
thanks in advance
