Summary: bug in paper metrics?
Initial Comment:
Hello there, Texies.
Is there a bug in the paper metrics of pdftex or in
an involved package?
Or just only in the acrobat reader?
I produce a pdf doc with pdftex. In particular I use
\documentclass[twoside,a5paper]{book}
.
.
.
\setlength{\topmargin}{-2.04mm}
\setlength{\textheight}{140.15mm}
\setlength{\textwidth}{99.1mm}
\setlength{\oddsidemargin}{-8.88mm}
\setlength{\evensidemargin}{7.63mm}
.
.
.
The Check produces:
1) a dump of \the\paperwidth in the logfile
gives 421.10078pt, which is 147.999999999mm.
2) the document properties in the acrobat reader
displays
148 x 210 mm
3) invoking printing on my canon i450 opens a window
in which
the field preview tells
Paper: 209.97 x 296.7 mm (I have DINA4 mounted, so
far, so good)
Document: 147.8 x 209.9 mm
4) DINA5 has exactly 210.22 x 148.65 mm
5) DINA4 has exactly 297.30 x 210.22 mm
What width my document really has?
148mm or 147,8mm or 148,65mm ??
There is physically only one!
And what I assumed and need is a width of 148,65mm.
How to apply?
Moreover, gluing 2 pages of my doc together with the
pdfpages package
works fine. 2 DINA5 onto 1 DINA4. In particular I use
\documentclass[twoside,a4paper]{book} However,
because a DINA5-page
misses approx. 0.65mm, some additional adaption is
necessary.
However, pdfpages applies a parameter for that
action. good luck.
The Check produces:

2) the document properties in the acrobat reader

297 x 210mm
3) invoking printing on my canon i450 opens a window
in which
the field preview tells
Paper 209.9 x 296.7mm
Document 296.7 x 209.9mm
General question: IS THE PAPER-metric FOR DINA5 AND
DINA4 CORRECT
IN THE APPROPRIATE PACKAGE?

1a) A logged metric of pdfpages compilation which
keeps the DINA5 is:
421.10124pt x 597.50829pt
which is 148.00015991mm x 210.0001462mm.
1b) A logged metric of pdfpages compilation which
keeps the DINA4 is:
597.50787pt x 845.04684pt
which is 209.9999986mm x 296.9999963mm
2) Some conversions:
72,27 point (amerikanische) sind 1 inch -- exakt!
1 inch sind 25,4 mm -- exakt!
72,27 point/ 25,4 mm = 2,845 point/mm oder 0,3513
mm/point.
dots sind nicht points und schon gar nicht pixel.

http://www.cl.cam.ac.uk/~mgk25/iso-paper.html:
DIN A4: 148mm x 210mm
= 421.10078740157pt x 597.50787401575pt
= 419.52755905512bp x 595.27559055118bp
article.cls:
\DeclareOption{a5paper}
{\setlength\paperheight {210mm}%
\setlength\paperwidth {148mm}}
log file:
paperwidth: 421.10078pt
paperheight: 597.50787pt
pdfpagewidth: 421.10078pt
pdfpageheight: 597.50787pt
PDF /MediaBox:
/MediaBox [0 0 419.528 595.276]
pdfinfo:
Page size: 419.528 x 595.276 pts
AR5/Linux:
148 x 210 mm
419.5 x 595.3 pt (points in AR are bp in TeX!)
Conclusion:
* All values are correct (modulo rounding errors).
* No bug.
