dvi paper-size

dvi paper-size

[Peter Münster]

Hello,

here comes a feature request:

Could ConTeXt add to the dvi-file information about paper-size, so that one
does not need the -t option of dvips?

This is done in LaTeX (+hyperref) by using something like
\special{papersize=...} but I didn't get it working in ConTeXt...

TIA for any help!
Cheers, Peter

Should be e.g. for "A4" \special{papersize=210mm,297mm} and for "A5" 
\special{papersize=148mm,210mm}.
If I add this, it actually seems to work here. I failed to create 
something which obtains the papersize automatically.

Yes, that's the problem. I tried
\special{papersize=\paperwidth,\paperheight}
and
\special{papersize=\PtToCm{\paperwidth},\PtToCm{\paperheight}}
Perhaps we need a \PtToMm{...} ?

Ok, the following works:
    \special{papersize=\the\paperwidth,\the\paperheight}

It puts (for \setuppapersize[letter][letter]) the following into the DVI 
file (dvips -d3 test2.dvi 2>&1 |grep special):
papersize=614.295pt,794.96999pt  which gv shows as letter.
Having the right unit (as defined in page-lay.tex, i.e. 148mm×210mm for 
A5, 8.5in×11in for letter etc.) would be probably better, but this works.

That expands to:
   papersize=\paperwidth ,\paperheight
which dvips cannot digest.

Whereas that expands to

papersize=\begingroup \scratchdimen \paperwidth \relax \scratchdimen 
0.0351459804\scratchdimen 0.0cm\endgroup ,\begingroup \scratchdimen 
\paperheight \relax \scratchdimen 0.0351459804\scratchdimen 0.0cm\endgroup
<cmr12.pfb>[1Processing special: papersize=\begingroup \scratchdimen 
\paperwidth \relax \scratchdimen 0.0351459804\scratchdimen 
0.0cm\endgroup ,\begingroup \scratchdimen \paperheight \relax 
\scratchdimen 0.0351459804\scratchdimen 0.0cm\endgroup

still something dvips cannot digest.

I have to admit, I actually fail to expand
   \special{papersize=\PtToCm{\the\paperwidth},\PtToCm{\the\paperheight}}
correctly. It always ends up as \begingroup ... in the DVI file (i.e. as 
above with \paperheight|weight replaced by its numerical value).

\PtToCm contains assignments, so it won't expand. Here is a macro
that does basically the same, but in a different order.

\def\writepapersize{%
    \begingroup
    \dimen0 0.0351459804\paperwidth % 2.54/72.27
    \dimen1 0.0351459804\paperheight
    \special
      {papersize={\withoutpt\the\dimen0 cm,\withoutpt\the\dimen1 cm}%
    \endgroup
}

how about adding something to spec-tr:

\definespecial\dosetuppaper#1#2#3%
   {\special{papersize=#2,#3}}

paper size is already supported in the other backends for ages -)

is this special official?

we can use etex to get a fully expandable one:

\def\metricdimension#1{\the\dimexpr0.0351459804\dimexpr#1\relax\relax cm}

\def\writepapersize
   {\special{papersize=\metricdimension\paperwidth,\metricdimension\paperheight}

Hello Tobias,
thank you! (I really don't know, why I forgot to test this alternative...)

Hello Hans,
I don't know, but here some lines from the dvips man-page:

-t papertype
       [...] You should not  use  any  -t  option
       when  the DVI file already contains a papersize special, as is done
       by some LaTeX packages, notably hyperref.sty.

Greetings, Peter

It's in the dvips manual as well:

   The format of the papersize special is

   \special{papersize=8.5in,11in}

   where the dimensions given above are for a standard letter sheet. The
   first dimension given is the horizontal size of the page, and the
   second is the vertical size. The dimensions supported are the same as
   for TeX; namely, in (inches), cm (centimeters), mm (millimeters), pt
   (points), sp (scaled points), bp (big points, the same as the default
   PostScript unit), pc (picas), dd (didot points), and cc (ciceros).

   For a landscape document, the papersize comment would be given as

   \special{papersize=11in,8.5in}

It appears to be dvips-only, judging from the hyperref .def files.

Ok. By the way, inserting in pt, cm or mm all works; i.e. this simple 
definition is ok, one does not need to convert to cm.

> is this special official?
Hmm, I don't know how official it is, but it is used by hyperref and 
documented, e.g. at
http://www.ifi.uni-klu.ac.at/Public/Documentation/dvips/dvips_3.html; 
this document is for dvips version 5.58f (January 1995). One can thus 
expect that is is actually supported by most installed TeXs ;)

ok, so i'll add it to spec-tr.tex

thanks for doing the research
