A solution to my own problem. This is from a category I created for
PDFDocument. Seems to work. The + and - 1's are strictly trial and error. Seems
to work, even with some pretty complex PDFS (created by comicLife, for
instance). Probably not the pithiest way to do this (ans is completely
superfluous) but for the record:
-(PDFSelection *) selectFrom: (int) b to: (int) e
{
int bspot, espot;
int i, n;
int flag, totlen, plen;
PDFPage *bpage, *epage, *tpage;
PDFSelection *ans;
totlen=flag = 0;
if(!(b < e)) return nil;
n = [self pageCount];
for(i = 0; i< n; i++)
{
tpage = [self pageAtIndex: i];
plen = [[tpage string] length];
if(b < totlen + plen)
{
flag++;
bpage = tpage;
bspot = b - totlen;
}
if(b < totlen + plen)
{
flag++;
bpage = tpage;
bspot = b - totlen;
}
if(e <= totlen + plen)
{
flag++;
epage = tpage;
espot = e - totlen - 1;
}
if(flag >= 2) break;
totlen += (plen + 1);
}
if(flag < 2) return nil;
ans = [self selectionFromPage: bpage atCharacterIndex: bspot toPage:
epage atCharacterIndex: espot];
return ans;
}
