Re: [Veusz-discuss] Qt drops PostScript output

[Christian Ambros]

Hi,
that mysterious reason is, that they have old parsing pipelines which where 
upgraded enough to reshape the text and give a printable layout to it for 
proceedings. If one uses Tex, one doesn't have any of these troubles because 
any tex editor will have e/ps output option and papers in physics and astronomy 
are commonly written with tex.For those who think they can't give some priority 
to learning tex, there is lyx which is a what-you-see-is-what-you-get tex 
editor without the necessity of learning tex language.At my days at MPE, 16 
years ago, Pdf was at it's start to get common, but most papers where published 
as PS. I'm glad those days are over.
For images, png is the most convenient format because it has high quality with 
moderate size and has no disadvantages whether it's used on the web, on screen 
or printed. So no need to go on file formats which have to be specially treated 
like svg's alpha chanal.
Droping e/ps support for veusz will be a good thing.
Cheers,Christian

 Hi all,

Going further into the discussion, it is true that many journals
nowadays accept pdf, but for some mysterious reason, they prefer EPS in
their publications. Anyhow, I just now save a graph that I have in PDF
and did not observe many differences from the EPS output. So I assume
that it should be fine the switch to Qt5 nad to PDF as new standard. On
the other hand, at least in my Ubuntu Linux, the PDF to EPS conversion
is quite automatic. You just need to read the PDF file with the standard
reader, and then save it as EPS.

Cheers,
Gonzalo

Not sure it's just ancient academic pipelines. Libreoffice impress 
accepts eps images but not pdf...

Pdf has some advantages over ps/eps like they are easy to parse when 
ocr is used. Images can be taken from them and their data can be made 
available again. ps/eps have to be first translated to pdf to use all 
this on them. Python3 has good pdf-parsers for processing in PI and

Re: [Veusz-discuss] Qt drops PostScript output

[Fred Labrosse]

All,

I mostly use pdf, but sometimes I end up with very big pdf files (produced
by pdflatex, when including many pictures).  I then use ghostscript to read
the pdf and save another pdf that ends up much smaller.  Where this is
related is that I believe gs uses ps as the in between format.  So I guess
using gs to convert from pdf to ps (or eps) if needed is a possibility.
veusz in fact could use gs to do that conversion.

Just my 2p.

Fred

Unfortunately, yes.

There are tools to covert PDF to EPS, but I don't know if they are good 
enough.

[Veusz-discuss] Qt drops PostScript output

[Jeremy Sanders]

Hi -

Emmanuel has noticed that Qt 5 has dropped Postscript support - see 
https://github.com/jeremysanders/veusz/issues/152


If we're going to move to Qt 5 soon (Qt 4 is no longer supported), we'll 
need to use drop PostScript, use some sort of external library or 
implement our own output.


How many people are using PostScript?

Thanks

Jeremy
