[NTG-context] Translating PDF-files
Properly not really a ConTeXt question, but maybe nows the answer. Someone asked me how to convert a PDF to XML and back. The reasons is that he has a PDF in English, but he likes to have it also in Russian. His idea is to convert the PDF file to XML, translate the XML file with GoogleTranslate and convert the translated XML file to PDF. He asked me how to do this. Of-course it does not have to be a XML file, if GoogleTranslate can work with a TEX file, there is no reason not to do it. Does anyone know how to do this, or has pointers about how to do this? -- Cecil Westerhof ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

Re: [NTG-context] Translating PDF-files
If your acquaintance actually needs an accurate translation into Russian, I wonder why he would choose Google Translate for that. Remember that Russian has 7 cases, and a complex verbal system with many different forms, all of which need to be deduced by Google from the much poorer English prepositions and the verbal foms in the text. Even though the result will no doubt show cyrillic words, which looks interesting, the factual result will be rubbish, and most likely unintelligible to any Russian.

So, I started reading the chapter about 'Typesetting in METAPOST' and

Re: [NTG-context] Translating PDF-files
Off topic: Well, I speak Russian and some other languages. Yes you are right, the 5th case is the locative (after o), the 6th case is the instrumental. One does not count the cases everyday :-) It is not a language in general that is difficult, but the pair a language is in: the pair English-Russian is, in some aspects, more difficult than the other way around because of the choice for the perfective aspect or imperfective aspect of the tenses. An English text does not offer any clues as to which aspect to choose, but anyone who wants to speaks Russian has to decide instantly. A program is unlikely do that. These problems might not exist for the pair Ukrainian-Russian, or perhaps (?) Polish-Russian, or - who knows - Basque-Russian. The options for determine the appropriate aspect, if programmers succeed in building them at all, are, for example, not needed in the pair English-Dutch. The reversed pair Russian-English poses different problems, such as when and where to put an article. The program has to derive from the context whether a given Russian noun in the text should be interpreted as determined or undetermined, and then whether it is appropriate to put the article, etcetera.

Hi Gerard,
how about an alternative way to deal with this?
1. draw the text with Inkscape (put text on a path);
I think there is even a tutorial for this.
2. select the graphic and save it as *.eps
3. use pstoedit to convert it into *.mp
pstoedit -v -ssp -f mpost: foo.eps foo.mp
4. edit/scale the metapost graphic as you like

pic[n] := textext(\bfd\setstrut\strut#1) ;
pic[n] := pic[n] shifted - llcorner pic[n] ;
\stopMPdrawing}
\handletokens MetaPost is Fun!\with\whatever
But is won't run. The following message is generated:
The actual error message said
! Undefined control sequence.
\@@toks -\MPtoks
So add
\newtoks\MPtoks
After which you get
! Undefined control sequence.
\whatever ...endtoks #1\to \MPtoks \setbox \MPbox
so add
\newbox\MPbox
After that the file compiles but you get an empty image. There are two
things missing in the code. First you don't tell actually draw the
metapost drawing. for that, add
\MPdrawingdonetrue \getMPdrawing \resetMPdrawing
Still an empty page. Again the pic[n] is calculated but never drawn. So
add
draw p[n] shifted (n*1cm,0) ;
(or perhaps along a more sophisticated path),
and now you have a working example:
\newtoks\MPtoks
\newbox\MPbox
\resetMPdrawing
\startMPdrawing
picture p[] ;
numeric wid[], len[], pos[], n ;
wid[0] := len[0] := pos[0] := n := 0 ;
\stopMPdrawing
\def\whatever#1%
{\appendtoks#1\to\MPtoks
\setbox\MPbox=\hbox{\bfd\the\MPtoks}%
\startMPdrawing
n := n + 1 ; len[n] := \the\wd\MPbox ;
p[n] := textext(\bfd\setstrut\strut#1) ;
p[n] := p[n] shifted - llcorner p[n] ;
draw p[n] shifted (n*1cm,0) ;
\stopMPdrawing}
\starttext
\handletokens MetaPost is Fun!\with\whatever
\MPdrawingdonetrue \getMPdrawing \resetMPdrawing
\stoptext
You could also have just used the macros from meta-txt:
\useMPlibrary[txt]
\startMPdefinitions
newpath RotPath ;
RotPath = fullcircle scaled 3cm ;
\stopMPdefinitions
\starttext
\followtokens{Metapost is fun \quad}
\stoptext
@Hans: Perhaps we can have a more ConTeXtist interface to this macro:
\definetextonepath
[whatever]
[color=...,
style=...,
mp=..., % path specification
]
\whatever{Metapost is fun}

[NTG-context] \hangaround in xml mkiv
Dear All,
I am processing a docbook xml file, which works great (thanks to Wolfgang's
introduction to TEI).
I have some images and I want the text before and after them to wrap around.
This can be achieved through the command \starthangaround .. \stoparound.
Since the text that is to wrap around must be put between commands, I cannot
attach the image to the figure/graphic tags that are within that text. The
figure tag does not allow the para tag to be inserted, nor do other approprate
media tags.
Instead I attached them to the attribute 'role' of the para tag:
para role=dolce1abcdef abcef/para
In the environment file I specified this:
\xmlsetsetup{#1}{//para[@role]}{xml:chapter:para:role}
The hangaround environment is put in the accompanying startxmlsetups:
\startxmlsetups xml:chapter:para:role
\starthangaround{\externalfigure[\xmlatt{#1}{role}]}
\xmlflush{#1}
\stophangaround
\stopxmlsetups
I also added an \xmlflush, assuming that the text itself is processed there.
In a rough sense this works. There is a white angle in the text for the image.
However, the image itself slides away.
I am not sure what is going wrong. Has anybody got a clue?
Thanks!
Regards,
Robert

Each language pair and translation direction has its peculiar problems. Whether or not you are able to say it is pure speculation depends on how familiar you are with computer linguistics, and its progress in determining semantic content from texts (step 1) and rephrasing it in a given target language (step 2). I'm glad that you accept that it is about the pair and the direction of the translation. Robert It is not a language in general that is difficult, but the pair a language is in: the pair English-Russian is, in some aspects, more difficult than the other way around because of the choice for the perfective aspect or imperfective aspect of the tenses. An English text does not offer any clues as to which aspect to choose, but anyone who wants to speaks Russian has to decide instantly. A program is unlikely do that. I'm sorry, but that's pure speculation. It would be interesting to see research about machine translation for some particular language pairs, though.

[NTG-context] \getscaledglyph
Hi,
I did a rather huge update step from my working context 2010.09.29 to the
actual beta. I noted that \getscaledglyph doesn’t work anymore.
I use it a lot for symbol insertions like this:
\definefontsynonym [ArialU] [name:ArialUnicodeMS]
\definesymbol [Diameter] [\getscaledglyph{1.5}{ArialU}{\char2300}]
\def\Diam{\symbol[Diameter]}
\starttext
hello \Diam\ goodbye
\stoptext
( \getglyph seems to work as usual: \definesymbol [Diameter]
[\tfb\getglyph{ArialU}{\char2300}] )
Should I better change my definitions or is it just a bug?
Thank you
Greetings
Thomas
