Overall, I dont see why this needs precomputation.
If you give the flags sequential suffixes, eg.
u3_0
u3_1
u3_2
then you can do
get_flag(Real stemlength) {
flagname = .. // "u3"
int suffix = 0
int best = -1;
Real best_dist = INFINITY;
while (true) {
Box b =fm->get_char (flagname + string(suffix))
if b.empty() {
break;
}
Real dy = b[Y].length() - stemlength
if abs(dy) < best_dits {
best_dist = abs(dy)
best = suffix
}
suffix ++;
}
Mike promised he would have a look at an alternative implementation of
the C++ by the end of this week.
