To create a new font, edit a font definition file with text editor.
Then run make. This will run fontgen to create a corresponding .h
file that can be included in a program.
Here's an example format for a font definition file. The first line
is a comment, the second line defines the width of each font
character, and the third light defines the height of each font
character. The following lines describe the font characters. The
. characters indicate an off pixel and other characters (such as @ or
#) indicate an on pixel. The first character is the corresponding
ASCII symbol.
The font does not need to be contiguous. Empty entries will be
displayed as blanks. However, they will take up memory.
# This is a demo font with only 3 characters.
width=5
height=7

The font entries with indices below 32 can be specified using \nnn
where nnn is the octal representation for the desired index. For
example, here are three faces assigned to indices 1, 2, 3. Note,
index 0 cannot be used since this marks the end of a string.
# Here's a demo font of three faces.

The tricky bit is representing these codes in C. You have to do
something like tinygl_text ("\001\002\003"); An alternative, is to
assign these to printable characters. For example,
# Here's a demo font of three faces.

height=7

Then you can display them with tinygl_text ("ABC"); Unfortunately, the
font cannot display ABC as well. One solution is to load multiple
fonts and switch between them.
#include "faces5x7.h"
#include "font5x7_1.h"
tinygl_font_set (&faces5x7);
tinygl_text ("ABC");
tinygl_font_set (&font5x7_1);
tinygl_text ("ABC");
However, only one font can be active at a time.
