How to draw formula (math + chemistry), using canvas in javaME

[huuanh1987]

Hi everyone!
I'm doing an application, to help students, can study Math, Physics, Chemistry, an easily mobile.

However, now I'm having difficulties when drawing symbols.

For example:

H2SO4 + NaOH --> (Na)2SO4 + H2O

--->Help me !!!!

Do you need to draw them, or could you just use bitmap symbols via a "custom font" approach?

If the latter is enough, then take a look at these articles:

What do you mean by that?

You need to add all the required symbols inside the image and then you need to read the same and draw it. Explain your question in much more details.
