So I threw together a mildly cleaned up version and some test code:
it's pretty rough in some ways, but does wordwrap and stuff in a way not entirely differently than normal fonts in processing...
Code:/*
the basic idea is you have characters made up of
-----
|\|/|
-- --
|/|\|
-----
*
the patterns for each stored in a hashmap of arrays,
keyed on the letter, value is an array of which segments
to display, numbered thus:
----1----
|\ | / |
2 3 4 5 6
--7-- -8--
9 10 11 12 13
| / | \ |
----14----
0
*/
HashMap font = new HashMap();
void setup(){
size(250,250);
setupFont();
strokeWeight(2);
drawText("the quick brown fox 'jumps' over the lazy dog?!... - 0 1 2 3 4 5 6 7 8 9 ",10,10,200,8,16);
}
void drawText(String s,float x, float y, float maxwidth ,float w, float h){
float origx =x ;
s = s.toUpperCase();
String[] words = s.split(" ");
for(int wordptr = 0; wordptr < words.length; wordptr++){
String word = words[wordptr];
if(x + word.length()*w > origx+maxwidth){
x = origx;
y += h * 1.5;
}
for(int i = 0; i < word.length();i++){
drawChar(word.substring(i,i+1),x,y,w-3,h);
x += w;
}
x += w;
}
