Two recent notes from Xerox about Interpress subsets remind me that it
was in March 1985 that Xerox first announced Interpress; here it is
March 1987, and there is still no implementation of the full language on
the market. And the subsets that ARE on the market appear to be so
confusing that even Xerox can't keep straight what the various subsets
do. Quoting from two recent "explanatory" messages:
The 9700, 8700, and 4050 all support the Commercial Set of Interpress.
If you wish to use features of the Publication or Professional Graphics
Sets, you can attach a Front End Printing Service (FEPS), which converts
full Interpress to the Commercial Set by converting SOME of the document
to bitmap. But most documents can be generated by Commercial
Interpress. You need the FEPS to handle arbitrary rotations (90 degree
rotations can be handled by Commercial Interpress), non-horizontal and
non-vertical lines, curves, and colors.

--------------------------------
Comments on FEPS: This software was developped to have STAR documents be
printed on a commercial set printer. STAR documents fit in the
Publication set with some differences. For example, the curves are
implemented as straight segments. STAR does not implement "CURVETO,
CONICTO, ARCTO".
Arbitrary rotations are part of the Professionnal Graphic set but not of
the Publication set ( '5.2.2). FEPS would not understand them.
