Hans,
would it be possible to add an key to \setupinteractionscreen that
implements the /PrintPageRange key in the /ViewerPreferences dictionary
(https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#page=373)?
For example, "\setupinteractionscreen[range={2, 4-7, 10}]" should add
the "/PrintPageRange [1 1 3 6 9 9]" in /ViewerPreferences. (BTW, the key
name is the first one that came to my mind.)
This is extremely useful to help the user to print only the required
pages and not the whole document (which may be required only for viewing
purposes).
well, 'extremely' is a bit of a exaggeration i guess as most of these
fancy acrobat only features are hardly used or requested (i still have
to meet a publisher who wants anything fancy pdf anyway) so we're
talking of yet another feature creep that probably only one person
will use
anyway, that said, as we use abstraction and as we don't know pages in
advance the only way i'm willing to support it is by using the
(probably unknown) marked pages feature
\setupinteractionscreen
[print={foo,oof}]
\starttext
% \markpage[foo][1,4,5]
% \markpage[foo][+2]
\markpage[foo] foo \page
\markpage[foo] foo \page
\markpage[oof] oof \page
\markpage[bar] bar \page
\markpage[foo] foo \page
\markpage[foo] foo \page
\markpage[bar] bar \page
\markpage[foo] foo \page
\markpage[oof] oof \page
\markpage[bar] bar \page
\stoptext
Hans,
A question on the code in page-ini.lua.
Should there be a test for a '-' with subtraction from realpage if
present, as there is for '+' and addition to realpage, around line
number 28-30, or is it the case that it does not make sense to mark a
prior page? (If it does not make sense, why parse the '-'?)
i can't figure a reasonable meaning for minus (after all, we're past
that page then and this mechanism is for testing pages)
just to make sure that we have a number (but we ignore a -)
btw, a few decases ago we had a similar feature which we used to inject
pages from a different bin in the printer
Hans
