Hello!
I spent last afternoon building a simple web-based solution to create bitmap fonts for GE. I did it because I tested other solutions, but I faced different problems. Some are paid, other are limited, other work good only if you use fixed width TTF fonts.
Mine solution has some limitations yet (antialiasing problem; you need to print screen the result; it does not generate the one line sequence automatically etc.), but, in other hand, it works with fixed width/height and you can use Google Fonts (just put the Google Font name in the related field).
It is working very good on recent versions of Firefox and Chrome. Can't test on Safari. I put some presets below the parameter box. I will try to implement gradient colors using CSS3.
For now, what is important to me is to get feedback from you. Is it a good solution? Bad solution? The wrost trash you saw?

That's it.
