[Rd] Unpredictable EPS->PDF rotation (PR#4460)
Dear r-bugs,
When I create EPS files, they sometimes appear rotated in my LaTeX PDF
document and sometimes they don't. Two examples:
## x1.eps is not rotated in LaTeX
x <- seq(-1, 1, length=100)
postscript("c:/x1.eps", height=3, width=4,
horizontal=FALSE, onefile=FALSE, paper="special")
plot(x, dnorm(x), type="l")
dev.off()
## x2.eps is not rotated in LaTeX
x <- seq(-2, 2, length=100)
postscript("c:/x2.eps", height=3, width=4,
horizontal=FALSE, onefile=FALSE, paper="special")
plot(x, dnorm(x), type="l")
dev.off()
By LaTeX PDF, I am referring to the dvips->ghostscript pathway, but x2.eps
also rotates when distilled into PDF outside LaTeX. I have tried
ghostscript and acrobat, placed on a page or cropped, so the problem does
not seem to be confounded with particular PDF distillation software.
I'm aware of the pdf() device in R, but EPS files are a widely used format
to share scientific graphics, often winding up embedded in a PDF document
at a later point in the hands of an editor.
If at all possible, a more predictable postscript generator would be
appreciated, where EPS figures would not rotate when embedded in PDF
documents.
Regards,
Arni

The headers and bounding boxes of the two .eps files are identical and to the best of my eyesight they are also using the same coordinate system. -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.

The "bug" is in newer versions of gs (ghostscript) which does rotate plots under some circumstances by default. Of course, the authors of gs consider this a feature (called "AutoRotatePages"), but IMO it's been a very bad design-decision. Here, we have implemented a workaround by patching the "epstopdf" (shell script) (we use the version from teTeX), by the following: --- epstopdf.~1~ 2002-04-20 00:00:00.000000000 +0200 +++ epstopdf 2003-03-13 16:43:53.000000000 +0100 @@ -182,6 +182,8 @@ ### open output file if ($::opt_gs) { my $pipe = "$GS -q -sDEVICE=pdfwrite $GSOPTS " . + "-dAutoRotatePages=/None " . ## MMä: <<<< This is the fix I found via google +## http://lists.debian.org/debian-tetex-maint/2002/debian-tetex-maint-200202/msg00013.html "-sOutputFile=$OutputFilename - -c quit"; debug "Ghostscript pipe:", $pipe; open(OUT,"|$pipe") or error "Cannot open Ghostscript for piped input"; ------------------- I'm interested to hear about more current workarounds / "official" ways to deal with this ``cool gs feature'' ..

I found that x1.eps is not rotated by Distiller, but x2.eps is. That's not a bug but intentional: Distiller (on its default settings) does auto-rotate individual pages of eps files. My guess is that gs is doing something similar on your setup -- it rotates for me under gs8.00 unless I set AutoRotate to /None (I used Convert in GSView to do so).> explain it.

Using Red Hat 9, I imported the two files x1.eps and x2.eps as output by R-1.7.1 into a groff document, both on one page and one above the other, outputting the result as a PS file, temp.ps. Using ghostview, the result displayed fine: right way up. Then distilled this to PDF, using (a) ps2pdf from ghostscript 7.05, then (b) epstopdf from TeX (though this too calls ghostscript). In both cases, the entire page displayed in Acrobat Reader rotated right through 90 degrees, i.e. the wrong way round. Then I transferred the temp.ps file to two other machines. [A] On one, SuSE Linux 5.2, I have an elderly copy of PStill (See Frank Siegert's site http://www.pstill.com ) which actually is a better distiller than ghostscript provides. The resulting PDF displayed right way up using acroread 3.0. I then converted to PDF using ps2pdf (ghostscript 5.10) and again it was the right way up. [B] On the other, SuSE Linux 7.2, I converted using ps2pdf (ghostscript 5.50) and again it was the right way up when viewed with acroread 4.0. Then I transferred both PDF files, from [A] and from [B], back to the original Red Hat 9 machine and viewed each using aroread 5.0, and they were still the right way up. It would seem from this that the problem arises with the distillation using ghostscript 7.05 (I don't have access to Acrobat Distiller). BY THE WAY: I had a look at the PostScript code in the EPS files from R, and noticed that the begin-page and end-page definitions use double invocations of gsave and grestore: /bp { gs gs } def % begin .ps.prolog /gs { gsave } def /gr { grestore } def /ep { showpage gr gr } def This doesn't strike me as necessary, so (in case it might have something to do with it) I removed one of them in each case: /bp { gs } def % begin .ps.prolog /gs { gsave } def /gr { grestore } def /ep { showpage gr } def to see if it made any difference (it didn't). I hope this helps to advance the investigation! Best wishes, Ted.
