Summary0010124: ImageIO methods ReadBufferAsASCII and WriteBufferAsASCII do not handle signed and unsigned chars correctly
DescriptionThese methods read or write the character as a single character and not as a number. That is if a pixel has the value 48 then "0" is written instead of "48".

This is different then what is needed for the VTK file format.
Steps To Reproduce
Additional InformationProposed solution:
template <class TComponent>
void WriteBuffer(std::ostream& os, const TComponent *buffer, ImageIOBase::SizeType num)
{
  const TComponent *ptr = buffer;
  typedef typename itk::NumericTraits<TComponent>::PrintType PrintType;
  for (ImageIOBase::SizeType i=0; i < num; i++)
    {
    if ( !(i%6) && i )
      os << "\n";
    os << PrintType(*ptr++) << " ";
    }
}
