Subject: Re: different image orientation with pdf and pdflatex

 I've noted that in AMS unnumbered report and in 
 KomaScript book documents (maybe also in some others
 or all the others document styles, dont know) the
 graphics images are placed in pdflatex exports 90
 degrees relative to pdf exports
 
  Why is this happening?

This happens in all document classes. Pdf-images in landscape format are 
always displayed in portrait format within LyX. But in the pdf-output 
should be OK.
LyX uses the program ImageMagick to display images. Possibly ImageMagick 
can't keep the format information.
I looked in the description of ImageMagick and can't find anything about 
this.

It seems to me that this problem is more gs related than ImageMagick related,
because it happens with vector-like eps files where IM is not used.

My understanding of the problem is that epstopdf 
(which uses gs pdfwrite output option) includes some automatic rotation
algorithm when the eps file does not clearly indicate what to do.
Everything is OK with eps creation software which ignores orientation
like xfig, but I get failures e.g. with matlab eps export when the landcape
orientation has been selected, or with eps from unknowm origin.

Seems that the problem comes from the fact that latex/dvips ignores these
orientation instructions (which seems a logical behaviour for EPS), 
but that gs tries to interpret them, so there
is a conflict between the dvips output and the pdf output.

This has been discussed already in the list, what is the status to deal
with this (boring) problem ?
 - upgrade gs ? (AFPL Ghostscript 7.04 here)
 - use an overlooked gs option preventing this (I thought that
 asking for compatibility with pdf 1.1 could do it, but no)
 - ask for an upper pdf level (her ps2pdf13)
 - rotate the faulty epses in the LyX/Latex doc ?
 - filter the said faulty epses ?
 
Any robust workaround ?

This happens both with ps2pdf and with sperate use of epstopdf on each file
(as tex2pdf does).

If you can isolate the 'faulty' snippet of postscript, it is trivial
to filter the eps file through sed.

We could certainly modify our eps - bitmap filters (for display on
the LyX screen) and our eps - pdf filter (for export to pdflatex).

how to keep local config files between lyx updates

[Pete Phillips]

Hi all.

Up until recently I used to have lyx centrally installed on our NFS
server, which meant that I could just copy our letter and memo layouts
and templates to the new installation when I upgraded and everyone
automatically had access to them.

However, for various reasons it is no longer practical to do this. Thus
I am looking for a method of keeping local templates/layouts in a
separate directory tree on each workstation. Is it possible to configure
lyx to look in an additional directory for these types of files ?

(Clearly, I also have the same requirement with tetex - if you know of a
pointer on how to deal with this in tetex, I'd appreciate a push in that
direction also.)

Cheers,
Pete

Gerhard,

  Look for headers and footers. Also, the fancyhdr package will do
exactly what you want. It lets you specify the text for both headers and
footers. You can make them the same or dependent on the page number being
even or odd.

Re: SOT: meaning of mathematical binary operators

Hello Rich,

I think, as with any other symbol, the meaning depends on the context. As
of right now, I am doing my homework on differential topology, and the
circled product represents the tensor product. I remember some other cases
where circled operators were used to denote vector/matrix operations, as
opposed to their scalar counterparts.

Pablo,

  Thanks to you and the others who directly replied. I now understand that
these symbols derive from Lewis Carroll's, Through the Looking Glass,
where things are what you're told they mean. Nothing less and nothing more.
My problem, as one respondent pointed out should I chose to use them, is
defining just what _I_ mean by their use. What prompted my question is that
in the contexts in which I find them, the author does _not_ explain their
use. At least, not so a mere ecologist like me can intuit what he means.

  Here's an example from Hans Zimmerman's Fuzzy Sets, Decision Making and
Expert Systems, in the section on fuzzy game theory:

  We will start with considering two-person games and specify what is meant
by a classical two-person-nonzero-sum game. Let s_ik \in k=1,2 be the ith
pure strategy of player k. For any pair {s_i1,s_j2} from S_1 \oplus S_2
there exists a unique real number g_k(s_i1,S_j2) \in G_k which is called the
gain of player k.

  I've seen these in may other writings of fuzzy sets, logic and system
models. Over the years I've learned a lot of mathematics on my own, but it
helps to have a dictionary of symbolic usage to which I can refer.

Many thanks, all of you!

\oplus is frequently read as direct sum, but in the context quoted

 not using the more common \times I have no idea.)

Christian,

  I've encountered the Wolfram site before. Yes, one should be more of a
mathematician than I am to easily read and understand what they provide.

  Related to this is a tendency for academicians to assume that everyone
reading what they write (or listening to them speak) is as knowledgeable as
they are in the subject being discussed. When one leaves the Ivory Tower for
the real world it quickly becomes apparent that decisions are made by
non-technical folks. Those who cannot clearly communicate complex technical
issues to this audience fall by the side of the road and never complete the
journey. Or, they become geeks and SysAdmins. :-)

Rich

Which is a valid assumption since the people reading what most academics write 
are other academics. 

The corollary of this (did I use the correct word? I can never remember), 
academics write their research papers for other academics, not the general 
public.

To me a circle with a plus sign is XOR :) or a hot cross bun. I believe the 
later interpertation should sit well with most LyX users. You should get one 
now!

It seems to me that this problem is more gs related than ImageMagick related,
because it happens with vector-like eps files where IM is not used.

My understanding of the problem is that epstopdf 
(which uses gs pdfwrite output option) includes some automatic rotation
algorithm when the eps file does not clearly indicate what to do.
Everything is OK with eps creation software which ignores orientation
like xfig, but I get failures e.g. with matlab eps export when the landcape
orientation has been selected, or with eps from unknowm origin.

Seems that the problem comes from the fact that latex/dvips ignores these
orientation instructions (which seems a logical behaviour for EPS), 
but that gs tries to interpret them, so there
is a conflict between the dvips output and the pdf output.

This has been discussed already in the list, what is the status to deal
with this (boring) problem ?
 - upgrade gs ? (AFPL Ghostscript 7.04 here)
 - use an overlooked gs option preventing this (I thought that
 asking for compatibility with pdf 1.1 could do it, but no)
 - ask for an upper pdf level (her ps2pdf13)
 - rotate the faulty epses in the LyX/Latex doc ?
 - filter the said faulty epses ?
 
Any robust workaround ?

This happens both with ps2pdf and with sperate use of epstopdf on each file
(as tex2pdf does).

Could you ask on a gs mailing list?

If you can isolate the 'faulty' snippet of postscript, it is trivial
to filter the eps file through sed.

We could certainly modify our eps -> bitmap filters (for display on
the LyX screen) and our eps -> pdf filter (for export to pdflatex).

Sure, but I need a "good" example to support my requirement.
I did not had a great success when I asked the forum about
undocumented options in the past :-(
When I get some time to spare, I'll look at it.

By the way, the currect workaround I use to solve this for video presention
is to export each page as an eps and to build a new document
including these graphics.

how to keep local config files between lyx updates

[Pete Phillips]

Hi all.

Up until recently I used to have lyx centrally installed on our NFS
server, which meant that I could just copy our letter and memo layouts
and templates to the new installation when I upgraded and everyone
automatically had access to them.

However, for various reasons it is no longer practical to do this. Thus
I am looking for a method of keeping local templates/layouts in a
separate directory tree on each workstation. Is it possible to configure
lyx to look in an additional directory for these types of files ?

(Clearly, I also have the same requirement with tetex - if you know of a
pointer on how to deal with this in tetex, I'd appreciate a push in that
direction also.)

Cheers,
Pete

Headline and footline

[Gerhard Lindel]

Dear list,
I have to use headlines and footlines (not footnotes) in my document.
Both lines have to have the same text on every page. I hope it is easy 
to realise,
but I cannot find the right way.  In the manual I only find footnotes 
and no headlines and footlines.
I'll be thankfull for help.

Gerhard,

  Look for "headers" and "footers". Also, the fancyhdr package will do
exactly what you want. It lets you specify the text for both headers and
footers. You can make them the same or dependent on the page number being
even or odd.

HTH,

Re: SOT: meaning of mathematical binary operators

[Pablo Diaz-Gutierrez]

Hello Rich,

I think, as with any other symbol, the meaning depends on the context. As
of right now, I am doing my homework on differential topology, and the
circled product represents the tensor product. I remember some other cases
where circled operators were used to denote vector/matrix operations, as
opposed to their scalar counterparts.

Cheers,

Pablo,

  Thanks to you and the others who directly replied. I now understand that
these symbols derive from Lewis Carroll's, "Through the Looking Glass",
where things are what you're told they mean. Nothing less and nothing more.
My problem, as one respondent pointed out should I chose to use them, is
defining just what _I_ mean by their use. What prompted my question is that
in the contexts in which I find them, the author does _not_ explain their
use. At least, not so a mere ecologist like me can intuit what he means.

  Here's an example from Hans Zimmerman's "Fuzzy Sets, Decision Making and
Expert Systems", in the section on fuzzy game theory:

  "We will start with considering two-person games and specify what is meant
by a classical two-person-nonzero-sum game. Let s_ik \in k=1,2 be the ith
pure strategy of player k. For any pair {s_i1,s_j2} from S_1 \oplus S_2
there exists a unique real number g_k(s_i1,S_j2) \in G_k which is called the
gain of player k."

  I've seen these in may other writings of fuzzy sets, logic and system
models. Over the years I've learned a lot of mathematics on my own, but it
helps to have a dictionary of symbolic usage to which I can refer.

Many thanks, all of you!

\oplus is frequently read as "direct sum", but in the context quoted 
above I think Zimmerman is using it to mean cartesian product. (Why he's 
 not using the more common \times I have no idea.)

It looks like S_1 \oplus S_2 means the direct product/sum of the sets S_1 
and S_2, i.e. elements in S_1 \oplus S_2 are members of the set

{ (x,y) : x \in S_1, y \in S_2 }

I've seen \oplus used in this way (although I'd say a \times has been more 
common, but I'm used to working with vector spaces where the direct sum 
and direct product are the same).

Here's a page that "explains"(*) the direct product:

http://mathworld.wolfram.com/DirectProduct.html

the site also has other "explanations" (*). Have fun ;-)

Christian,

  I've encountered the Wolfram site before. Yes, one should be more of a
mathematician than I am to easily read and understand what they provide.

  Related to this is a tendency for academicians to assume that everyone
reading what they write (or listening to them speak) is as knowledgeable as
they are in the subject being discussed. When one leaves the Ivory Tower for
the real world it quickly becomes apparent that decisions are made by
non-technical folks. Those who cannot clearly communicate complex technical
issues to this audience fall by the side of the road and never complete the
journey. Or, they become geeks and SysAdmins. :-)
