Hi.
I send to you a copy of a discussion about the TeX system. This is
meant to reach xdvik mantainer but following AUTHORS directive I send
it at this address. Cc: to Rokicki and to a co-sytem manager here.
TIA...
******** I said:
Hi,
I have a problem with dvips 5.58f. It seem that if the TeX file
contains a global \magnification then dvips applies this magnification
to the inserted postscripts too (that's IMHO a Bad Thing). You can try
with the following file:
\magnification=\magstep4
\input psfig
\null
\psfig{figure=angel.eps}
\bye
where angel.eps is a bitmap (in my case the university logo). If you
see it with xdvi with ps capability the logo have his natural size,
and the same things happen if you covert it to ps with dvips 5.511,
but if you use dvips 5.58f the angel will show up 4 time bigger...
Can you help me please?
Thanks in Advance,
Romano.
****** Tomas G. Rokicki <rokicki@CS.Stanford.EDU> Answered:
Global magnification *must* affect included PS files; this is something
I've been arguing for years. Otherwise the -x option doesn't work, and
dvidvi (and other pagination/scaling software) doesn't work. If he
wants his angel to appear at a particular size independent of
magnification, all he has to do is specify what that size is (in epsfxsize)
as a truept parameter and all will be fine.
******* So I replied, with an horrible itaenglish:
Well,
I can be IMO in accord with the filosofic thing that
\magnification in TeX document will work with included postscript
too. I will correct the angel situation :-) simply addind a truept
specificacion in the call but... now we have a problem of
coordination: xdvi shows a page layout that generally is different
to the printed page. I know, I know, i can use gv but it is so slow
on old machines :-).
Well, if you have any hints... what about a flag in config.ps
BROKEN_INCLUSION_COMPATIBILITY? Only as a suggestion... I will forward
this e-mails to the xdvi mantainer if you like.
By the way, great work, TeX and company installation now is
really a breeze.
Bye,
Romano.
******* "Tomas G. Rokicki" <rokicki@CS.Stanford.EDU> finally replied:
Oh, I wasn't aware that xdvi did it differently. Please do forward the
message to the xdvi maintainer and tell him/her that I would be delighted
to help in any way . . . it's important that dvips and xdvi work well
together . . .
Most of the credit goes to Karl Berry for the TeX stuff, for sure, but
thanks for the nice words!

********************
So now I ask to you for a possible solution. The real big problem is
not if you have to specify or not the size with truesomething in your
source, but that my little file above with or without magnification
show up identical in xdvi (well, the pagenumber is different of
course), and then the printed page from dvips look really different.
Hope this helps to TeX community (and to me :-)),
Have a nice week end,
Romano.
