    IFXers,
     
    Due to some error that were found in the specification of the 'Tiling' operator,
    I am proposing to revise the specification of this operator as shown in the PDF
    at this link:
     
    <ftp://ftp.pwg.org/pub/pwg/QUALDOCS/other/Tiling-Operator.pdf>
     
    In addition to fixing some general problems, I have also specified the order in
    which the tiles must appear in the stream. The tile ordering can no longer be
    ordered at the whim of the Producer. This ordering: left to right, top to
    bottom, follows the image pixel data ordering that is called for in the spec.
    It should also be noted that the orientation of the page relative to this
    ordering can be arbitrary. The page could be either landscape or portrait as it
    is defined in the Page object's 'Media Box' field.
     
    I'm submitting this change independent of a new release to solicit comments on
    this change before the next release of the PDF/is spec is made.
     
    Thanks.
    -Rick
