[Severin Obertuefer]

Hi

I made a context-file that contains a lot of *.jpg pictures. The file is
very big now, because the pictures are in good quality.
I'll use the document for the web and I think there you can see no more then
72dpi (I'm not shure with that)
Is there a command to set down the resolution of the whole document
(including the pictures) ?? or do I have to reduce the resolution of each jpg graphic
with a graphic-program.

if you have a recent context, you can run

   pstopdf --method=4 somefile.pdf

and get a lowres file. This program is written in ruby and assumes that you 
have ruby as well as GS installed.

i get an error when I try this: "pstopdf" can not be found ...
I use MS Windows and Miktex. GS is installed and I downloaded ruby for
Windows as well...

do I have to install "pstopdf" seperatly?

Just a wild guess: since you need ruby installed and a recent
ConTeXt, pstopdf is a ruby script shipped with ConTeXt. But Hans
forgot to pack the ruby scripts in the last beta (iirc).

So GS is not in the path. Add to your path

<path-where-you-installed-GS>\bin;
<path-where-you-installed-GS>\lib

It is important to put both ..\bin and ..\lib in the path: the
first one contains the executable, the second one contains
(among other things) the pstopdf batch file.

And remember to reboot for maximum assurance that the changes
stick :)

I recently had the same question with my MikTeX / gs /WinXP installation.

It seems that pstopdf is nowhere on my machine.

There is epstopdf, a different thing, but it doesn't do what pstopdf does.

pstopdf is just a simple batch file pointing to gs, with certain options
specified.  I'm about to get around to simply rewriting the Unix version of
pstopdf for DOS.  Unless someone has already done it ....  anyone??

yes that's right, but I think that ps2pdf and pstopdf is not the same...
ps2pdf is a batchfile in the gs library
and pstopdf is a ruby "script" which is packed in the "cont-exa.zip". this
need ruby and gs.

on my system both programs are installed and i have set a path to all these
directories. but when I run
"exampler.rb --continue" it seems that I don't have some files:

C:\Programme\texmf\context\examplap\scripts>exampler.rb --continue
exampler  +  program exampler
exampler  +  version 1.0
exampler  +  author PRAGMA POD
exampler  +  commandline "--continue"
exampler  +  using environment setuppath C:/Programme/texmf/context/ruby
exampler  +  loading ./example.exa
exampler  -  sub environment file machine.exa not found
exampler  -  sub environment file presets.exa not found
exampler  +  !! checking if texroot is set to a valid path !!
exampler  +  !! setting variables based on kpsewhich !!
exampler  -  sub environment file paths.exa not found
exampler  -  sub environment file local.exa not found
exampler  +  gone to jobpath C:/Programme/texmf/localtexmf/examplap/jobs
exampler  +  jobpath C:/Programme/texmf/localtexmf/examplap/jobs
exampler  +  resultpath C:/Programme/texmf/localtexmf/examplap/results
exampler  +  server started on 127.0.0.1:8061
exampler  +  listening at 127.0.0.1:8061 in loop mode

and when i type "pstopdf --method=4 r.pdf" the the conversation never ends
and "gswin32" takes almost all my RAM!!

what can I do?

I know nothing about Ruby, and its not on any of my systems.
AFAIK, ps2pdf on Windows is identical to pstopdf on Linux (and OSX).
It (they?) are distributed with gs, not ConTeXt, and call gs, no Ruby
involved.
I have no idea why it has two names.  Maybe I've missed something.

If you are trying to accomplish something that the Ruby version offers ... I
can't help you there.
If you are simply converting [e]ps to pdf, try ps2pdf and see if you get
what you want.

what a coincidence that texshow-web and exampler are listening on the
same port!

> what can I do?

perhaps try to run gswin32 with the options that are used in pstopdf
(ruby). I think that the relevant section is:

 def downsample (program, inpfile, outfile)

    process = program + ' ' +  
              "-dPDFSETTINGS=/screen -dEmbedAllFonts=true " + 
              "-dSAFER " + 
              "-q -sDEVICE=pdfwrite -dNOPAUSE -dNOCACHE -dBATCH " +
              "-sOutputFile=#{outfile} #{inpfile} -c quit "

    @exa.execute(process,false)

  end


so try gswin32 -dPDFSETTINGS=/screen -dEmbedAllFonts=true -dSAFER \ 
              -q -sDEVICE=pdfwrite -dNOPAUSE -dNOCACHE -dBATCH \
              -sOutputFile=out.pdf in.pdf -c quit 


(just a guess).

pstopdf.rb is a more extensive version of the eps to pdf converter in 
texutil.pl and uses GS for the conversion; however, pstopdf has a couple of 
extra features, like cropping, aggresive clean up of code, taking care of 
platform differences.

pstopdf.rb is also used by pstopdf.pdf i.e. a graphical user interface to 
ps to pdf conversion

pstopdf.rb can also watch folders and do automatic conversions

BTW, the manual can be downloaded from out site.

downsampling can take a while ... but it works here on 400 Meg files so ...

Ha .. wait till you see its bigger cousin (client runs on 8061/8063 and 
server on 8060/8062/8064) so you'd better not use 8060-8069

(fyi: 8061 is our postal code)

I don't know the meanig of this ip and this port! what is texshow-web?
I tried to get something about this from the internet, but i could not find
a lot of things.
once, my goal was to use the command "pstopdf --method=4 somefile.pdf"
