Beginnner's question: fumbling with font finding failures.

Beginnner's question: fumbling with font finding failures.

[Paul R Martin]

Dear ConTeXters,

I'm a newcomer to ConTeXt and to this congenial and obviously active  
list:  please bear with me and read my story. I'll be much more  
succinct in future.

Last week, I installed TeTex and ConTeXt [Mac OS X 10.3 "Panther"]. I'm  
working my way through the "Excursion" and "This Way/ My Way"  
documents. They are great documents, ConTeXt is a great  package, and  
I've had some timely tips from Hans Hagen (Hail thee, Hans!). I've made  
some good progress. I have learned the difference between a  _Hasselter  
juffer_ and a _Hasselter bitter_, but I'm still not sure what one does  
with a _foekepot_. I suspect that it's a percussion instrument, but  
that's beside the point.

I have a history of user-level LaTeX formatting in my distant past.  
I've mostly been stuck in the dark, ragged, dreary, world of MS Office  
for the past decade, so you can understand my joy to see beautiful,  
colourful .pdf pages rolling up my screen, as a result of typing  
straightforward, comprehensible formatting commands in a plain text  
ascii file. As my fellow Australians would say: ** You little ripper!  
**

Now, I've managed to side-step some menacing signs of absent fonts as I  
progressed. My goals are straightforward (technical documentation and  
scientific writing), so I've been happy to accept the font  
fallback/replacement routines. Further, my glimpses into the pages and  
pages of information about font handling make me think that it's a kind  
of bad neighbourhood for a person like me to enter, just as it was when  
TeX and I were young.

But now I've struck the following blockade in my quest to produce a 'My  
Way' document, which I did by simply

	1) cutting and pasting the source code from the page 3 of My Way #0  
[mag-0000.pdf]
	2) changing the author name, and
	3) saving the resultant text as [mwy-000-Test.tex],  then
	4) running the perl "texexec" script on it.

OK, don't snicker, it may not be such a silly thing to try. I'm sure  
there are other people who might try this kind of approach. Here is the  
gist of the result -- ellipses mark my deletions.

------------------------------START---------------------------

---------------------------------------------FINISH-------------------

[etc etc, I think that 'nonstopmode' might have been why this loop  
continued for the next 120 seconds. BTW I typed 'Q' in response to the  
input file name request  above].

Now, it's obvious from the ContextGarden that I've probably missed some  
step in font configuration. But when I start to look in the numerous  
sources of advice, I strike the usual frustration. There are lots of  
statements (lots and lots of 'em!) about checking and un-commenting and  
configuring, but I can find no list of *prioritised* things for  
beginners to try, in the order which they should be tried, in order to  
solve what looks to be a simple and typical problem. Without such a set  
of instructions, I'm loath to change anything in my configuration, for  
fear that the cure might be worse than the disease.

I'd love to try to understand the source of the error, and how to  
handle fonts professionally, and lots of other things as well. But I'm  
a busy scientist with many other commitments. As long as ConText is  
working I'm happy, but  I can't devote much time to delving into  
errors. So I may not be a typical participant in this list. But if you  
help me,  you will help to make ConTeXt more accessible to others like  
me, and this will be good for the cause, _nes pas?_  I'd be happy to  
write a my way document or contribute a Wiki page on this topic to  
encapsulate any good advice for myself and other neophytes.

[Thomas A.Schmitz]

Glad you're enjoying your ConTeXt experience. Believe me: it's a great  
macro package, and it will grow on you.

To answer your question:  What you did is basically correct, however,  
there is a tiny mistake in the code in s-mag01.tex. The font  
declaration doesn't work out of the box with a current TeX distribution  
(I have lost track of all the changes in TDS etc. during the last  
months). I used the module a few days ago and meant to write a note to  
Hans, but then forgot. The easiest fix is:
1. Open s-mag-01.tex (which on your box, if you use Gerben Wierda's  
installer, should be in  
/usr/local/teTeX/share/texmf.local/tex/context/base/s-mag-01.tex

2. Locate the lines

\usetypescript
   [palatino][\defaultencoding]

\setupbodyfont
   [palatino,10pt]

3. Just before them, insert this line:
\usetypescript[adobekb][\defaultencoding]

4. Save the file and rerun, and you should be in business.

Good luck!

Thomas

Hi,

In my experience, I had to say:

\usetypescript [adobekb][\defaultencoding]
\setupbodyfont[pos]
\usetypescript[palatino][\defaultencoding]
\setupbodyfont[palatino,10pt]

in order to have any success in typesetting that file (under Mac OS X 
10.3.8 and Gerben Wierda's TeX).

Stopping and contiuning movies

[Albrecht Kauffmann]

Hi all,

is it possible to stop (and continue) a movie (at arbitrary time points)
that has been included how
described in the ConTeXt manual ch. 13.7 p. 302 ff.? To start the movie
using StartMovie works fine, but using StopMovie causes to abort the movie
instead of stopping.

With many thanks for any hint
Albrecht

Metapost animation

[Albrecht Kauffmann]

Hi Hans, hi all,

in an former mail you had answered to the question of Michal Kvasnicka:
"Is it possible to `animate'
> the fieldstack? In other words, to make it change one figure to
> another automatically, without clicking anywhere, changing one frame
> to another each 1/n second to simulate a smoth motion like in a
cinema?":

"sure, you can let a javascript toggle the states, ...".

Has someone already experience with such animated field stacks and can
give me some clue how to realize this?

With many thanks in advance
Albrecht

that should go in your local cont-sys.tex file; alternatively say

\usetypescript[berry][\defaultencoding]

Do you mean something like this?

\starttext
\startMPpage
a := 4;
label(decimal a, origin);
\stopMPpage
\startMPpage
a := a+1;
label(decimal a, origin);
\stopMPpage
\stoptext

Re: MetaPost Animation

[Troy Henderson]

>> \def\MyGraphics#1{%

Thanks for the replies folks.  The example that I posted is a simple
example.  The example that I'm working on (displaying successive terms
in a Taylor series) requires a bit of computations, and I don't want
to have to go back and do each computation for each value of #1.  That
is, I want to build a table of numerical values (numeric Y[][]) and be
able to address those values from my \startMPcode section.

If I have two different \startMPcode ... \stopMPcode sections, is
there a way (perhaps it does this by default) to have the variables
stored in the first block available in the second block?  In pure
MetaPost, I can do

numeric a:=4;
beginfig(1);
    label(decimal(a),origin);
endfig;
beginfig(2);
    label(decimal(a),origin);
endfig;
end

and both figures have the value of 'a' available to them because 'a'
was defined before each figure.  What is the ConTeXt way of doing
this?

Thanks,

Troy

local template = [[

Hi Troy

Here is a simple solution:

\def\MyGraphics#1{%
\startMPcode
path p,q;
p:=fullcircle scaled 72;
L:=length p;
N:=20;
q:=subpath (0,#1/N*L) of p;
draw q withcolor red;
fill fullcircle scaled 3 shifted point length q of q withcolor blue;
setbounds currentpicture to unitsquare shifted (-0.5,-0.5) scaled 75;
\stopMPcode}

\starttext
\dostepwiserecurse{0}{20}{1}{%
\startTEXpage
\MyGraphics{\recurselevel}
\stopTEXpage}
\stoptext

MetaPost Animation

[Troy Henderson]

I am trying to create an animation in ConTeXt + MetaPost.  In
particular, I would like to have ConTeXt + MetaPost generate each
individual frame of the animation, and then I would like to place each
of these graphics on the page in succession.  I am looking for a
"ConTeXt way" without placing the MetaPost code in a separate source
file, running MetaPost, and using \externalfigure.  The following
MetaPost sample code generate 21 graphics images  (numbered .0 to
.20), but I have no idea how to have ConTeXt generate these graphics
without a manual external MetaPost run and have them included in a way
that is consistent with \startuseMPgraphic or similar.

Thanks in advance,

Troy Henderson

path p,q;
p:=fullcircle scaled 72;
L:=length p;
N:=20;
for n=0 upto N:
	beginfig(n);
		q:=subpath (0,n/N*L) of p;
		draw q withcolor red;
		fill fullcircle scaled 3 shifted point length q of q withcolor blue;
		setbounds currentpicture to unitsquare shifted (-0.5,-0.5) scaled 75;
	endfig;
endfor;
end

Can someone please post any example of JavaScript code to "toggle the 
states" like in either http://www.math.muni.cz/~plch/nkpm/nradanm6.pdf 
or https://www.pragma-pod.com/present/talks/fifteen.pdf?

I produced the graphics as explained in the section 13.6 of the metafun 
manual, but I would like to press the button only once at the beginning 
of the animation instead of twenty times.

Thank you very much,

Good evening.

Many thanks for your answer. If it doesn't work for `small steps (<1s)', 
it's probably useless, since for a smooth motion at least 15 frames per 
seconds are needed. But anyway, what is `svg'? Where can I see `dante XV 
presentation'?

And one more question: Is sounds as system-dependent as movies? If not, 
how can I integrate it in a PDF document?

Many thanks and greetings.
Yours

sure, you can let a javascript toggle the states; however, small steps (<1 sec) are not to be trusted in precission, since they also depend on the machine; they also kind of block other actions since there is no concept of animation in pdf (apart from svg, which is poorly implemented/integrated).   

Another method is demonstrated in the 'dante XV' presentation (runs slightly faster on a mac than on windows);

Hm. Do you quote the Metafun manual, section 13.6? I know this 
technique. But my question was different: Is it possible to `animate' 
the fieldstack? In other words, to make it change one figure to another 
automatically, without clicking anywhere, changing one frame to another 
each 1/n second to simulate a smoth motion like in a cinema?

Many thanks to you and all who answered me.
Yours

it's in the metafun manual 

that kind of trickery has been present in context for a long time, but unfortunately it's not always available on each platform 

(apart from the fact that each version of acrobat has its own side effects)

That is Acrobat Reader. :-( Accept it as a fact that you need to do
your JS for a specific version of Adobe Reader.

It is up at

None at all.

You need automatic steps? If not, take a look at 
http://dl.contextgarden.net/examples/euro-anim/euro-anim.pdf

(this is explained in the metafun handbook; I could upload the source,
too).

Hans himself showed some examples some years ago at DANTE, a ticking 
clock, a spinning windmill etc.
(The clock is somewhere around AFAIK but works only with Acrobat 4)

Metapost animation

[Michal Kvasnicka]

Good evening.

First of all I want to thank to Mr. Hagen for his last answer. I will 
check your last code of balanced columnsets at home (with the newest 
ConTeXt). As for your correcting code for ordinary collumns, I have 
tried it with three different types of my documents, and it worked well. 
Maybe this is the final solution of the problem. I will try it with more 
documents and let you know, anyway.

Now to my next question. I have seen a great thing: Metapost pictures 
were animated (probably with the JavaScript code). You can found some 
examples here:
    http://www.math.muni.cz/~plch/nkpm/nradanm6.pdf
    http://www.math.muni.cz/~plch/nkpm/nradanm8.pdf
(Just click on the `Spustit animaci' button.)

Is it possible to do it simply in the ConTeXt? Of course I may break 
down the mechanism of widgets and write my own JavaScript (I don't know 
how to do timing), but isn't there some special macro for animating 
series of figures? It would be great.

If so, is Acrobat Reader fast enough to simulate this way the nice 
feature of MS PowerPoint---curves and shapes that are drawn by pieces, 
or that appear somewhere and then go to its final location? (This is 
quite instructive in economics, because you can easily notice which 
curve is drawn first, what second, and so on.) How can I do it?

With many greetings and thanks
Michal Kvasnicka
