[Bug-ocrad] A bug discovered

[Georgi Demirchev]

Dear Mr. Diaz,

Your application is great.
In function:

int Bitmap::analyse_layout( std::vector< Rectangle > & rv,
                            const int layout_level ) const throw()
  {
  rv.clear();

  if( layout_level >= 1 && layout_level <= 2 &&
      left() == 0 && top() == 0 && width() > 200 && height() > 200 )
    {
    Bitmap reduced( *this, 10, 9 );
    find_columns( reduced.data, reduced, reduced, rv, layout_level >= 2 );

---to be removed
    if( rv.size() > 1 )
to be removed---

      for( unsigned int i = 0; i < rv.size(); ++i )
        rv[i].enlarge( 10 );
    }
  if( rv.size() == 0 ) rv.push_back( *this );
  return rv.size();
  
The above if( rv.size() > 1 ) check causes the algoritm to behave
improperly when there is only 1 block in the page.

Regards,
Georgi
