Hi,

I'm in the middle of writting a PICT parser on a UNIX system and I need to
know something which does not seem to be documented:

   Q1:
   Is it possible to have a BitMap in a version 2 PICT ?
   The documentation seems to imply that PixMaps replace BitMaps in
   version 2 PICT files, but I wanted to make sure...

   Q2:
   IM V page 104 seems to say that the high bit of rowBytes tells you this,
   but in the same paragraph they say that "In general, the difference
   between version 1 and version 2 formats is that the pixMap replaces
   the bitMap..."  So, can I just check the PICT version instead of
   the high bit of rowBytes ?

Thanks,
