I think you're going off on a tangent here. Matroska can handle the 
VOSSUB subtitles from your DVD. Reconfigure your DVD subtitle ripper to 
rip the subtitles to VOBSUB.
Your utility is extracting to PNG files in anticipation that you want to 
OCR the subtitle into a text-based subtitle format like ASS or SRT. This 
is what many of us do as the result is much smaller subtitle 
files/streams and ultimately smaller multimedia files.The subtitles are 
editable as text format subtitles. Also, displaying these subtitles 
takes less CPU power than displaying VOBSUB subtitles.
