Letter fonts used in this tutorial:

* GDF fonts

* To be used in this exercise.

* Don't forget to save the fonts in folders visible to the proposed exercises.
Like example, this tutorial uses gdf and ttf, respectively.

* If you have other fonts, you can use them as long as they are usable.

* Solve, therefore, the exercises proposed.

$font can be 1, 2, 3, 4, 5 for built-in fonts in latin2 encoding.

The higher numbers corresponding to larger fonts or any of your own font identifiers registered with imageloadfont.
