Re: [NTG-context] fontsize drawing in metapost
The reason behind starting this thread was the fact that I want my
\useMPgraphic's arbitrarily (and perfectly) scaled. In Metapost/Metafun that is
easily done through a \MPvar{scale} variable, applied to the main dimensions on
which all measures in my figures depend. But for the fontsizes this turned out
to be not so easy. Understandable, because text is typeset at the TeX-end not
inside the Metapost.
Perhaps a better and possibly more elegant way seems the following route. When
I turn Metapost figures into external pdf-files, these can be placed with
\useexternalfigure and the scaled as a whole, drawing and text alike. My
question is: can this be done without resorting to an external pdf? That is,
can I pick up the result of \useMPgraphic somewhere, then put this in
\useexternalfigure and apply everything possible there to the figure.
Does someone know how to?

Thanks. This is exactly what is needed. I feel myself somewhat silly, because I

course. Now I know to do it right!

Re: [NTG-context] fontsize drawing in metapost

Re: [NTG-context] fontsize drawing in metapost
I did some further experimentation, hoping using dimexp calculations would
help. But either I am doing somthing wrong or I do not understand the innards
of bodyfont switching well enough.
The example program seems to have accessed a 30 pt font (see the log file) but
did not typeset in it, the dimexpr does evaluates to 30 pt.
Where am I at fault?

Re: [NTG-context] MetaPost Function Grapher
Hello Troy. Thank you very much for the link. It looks very nice and I'm sure that I will throw into teaching (I teach mathematics at the high school). I'm doing these things through Tikz and Pgfplots. Metapost unfortunately I don't control. Is it possible allowing export to Tikz or Pgfplots? If I would had the opportunity to also download the source Tikz or Pgfplots, it would be absolutely amazing. My point is that I can post the graphs still adapt, modify, describe, and create animations from those exported sources. Anyway, it's very hilarious application and I provide the link my students for their study purposes. Kind regards. Jaroslav Hajtmar Dne 22.2.2013 19:44, Troy Henderson napsal(a): The MetaPost output from my Function Grapher http://www.tlhiv.org/mpgraph/ is now available in ConTeXt format. This can be illustrated by choosing a graph type and selecting an example from one of the Example buttons.

Thank you for the explanation, and your sample works nicely.
I enclosed \processMPbuffer using \startframe and \stopframe as following.
Then I got a 'undefined control sequence' error.
If I use '\framed[]' instead of '\startframe … \stopframe', then it gave all 7
circles of different radius in two pages without error.
If I add \startanimation … \stopanimation, the only change is the appearance
of menu at the bottom of the last circle.(no animation)
What is wrong in the code?

Dear Wolfgang,
Thank you for the explanation, and your sample works nicely.
I enclosed \processMPbuffer using \startframe and \stopframe as following.
Then I got a 'undefined control sequence' error.
If I use '\framed[]' instead of '\startframe … \stopframe', then it gave all
7 circles of different radius in two pages without error.
If I add \startanimation … \stopanimation, the only change is the
appearance of menu at the bottom of the last circle.(no animation)
What is wrong in the code?
1. The \frame and \startframe commands are only available *in* the animation
environment where they are locally defined.
2. Although \framed sound similar to \frame there is no relation between both
commands.
3. You have to expand the loop value *before* it is passed to metapost, see
below.
\usemodule[animation]
\setupinteraction[state=start]
\startuseMPgraphic{circles}{counter}
path p;
numeric n, u;
u := 1cm;
n:=\MPvar{counter}*u;
p := fullcircle scaled n;
draw p;
\stopuseMPgraphic
\starttext
\startanimation[menu=yes]
\dorecurse{7}{%
\startframe
\useMPgraphic{circles}{counter=#1}%
\stopframe}
\stopanimation
\stoptext
4. You can also include the metapost code in the frame but you have to expand
the \recurselevel value with the \expanded command (I have to upload a new
version of the module first because \startframe isn’t expandable yet).
\usemodule[animation]
\setupinteraction[state=start]
\starttext
\startanimation[menu=yes]
\dorecurse{7}{\expanded
{\startframe
\startMPcode
path p;
numeric n, u;
u := 1cm;
n:=\recurselevel*u;
p := fullcircle scaled n;
draw p;
\stopMPcode
\stopframe}}
\stopanimation
\stoptext
5. Use a PDF viewer with javascript support (e.g. Adobe Reader) to view the
animation.
Kind regards and a happy new year,
Wolfgang

Re: [NTG-context] MetaPost Animations
Dear Troy,
The animations are impressive and thank you for sharing the code.
In the creation of many pdf for animation, it changes the recurselevel only.
I wonder if there is a way to make such kind of animation in ConTeXt using
Wolfgang's animation module.
Then we can include the animation in PDF output directly.
Here is my trial.
I modified it as following and got an animation. But it is only good for a few

You can use a loop to create the frames, the only thing you have to be aware is
how to access the counter loop iteration. In most cases you can get the current
iteration of the loop with \recurselevel but this doesn’t work for animation
because
each frame is saved in a symbol with \definesymbol[frame][code] without
expanding the content.
To fix this you can expand the content with \expanded{\frame{… \recurselevel …}}
or simpler by using “#1” instead of \recurselevel to access the counter.
The braces around each frame as in your example are only one method to set
the content for each frame (it emulates the \startoverlay and \startcombination
input), when you use a loop you have to use \frame{…} or \startframe …
\stopframe
to set the content for each frame.
Example:
\usemodule[animation]
\setupinteraction[state=start]
\starttext
\startanimation[menu=yes,framerate=10]
\dorecurse{99}
{\startframe
\definedfont[Mono sa 4]\twodigits{#1}%
\stopframe}
\stopanimation
\stoptext

Neat. MP - Flash seems to work well. One thing, which you may know, gear teeth do not normally have rectangular profiles. Nowadays, they are usually involutes of a circle and formerly were usually cycloids (so the gears don't slip against each other when they turn). I don't have a reference, but google turned up http://www.cadquest.com/books/pdf/gears.pdf, which shows how to draw involute gears. Are you using the animations, or some frames perhaps, in a ConTeXt document? I usually use Mathematica for such animations, but it and its ilk are expensive, although there are other alternatives. As I'm still learning MP/Lua/ConTeXt, I'm just interested in the ways others use the system. Thanks for sharing.

The webpage will soon allow for downloading the source for each ConTeXt document. This generates a multi-page PDF where each page of the PDF is a frame of the animation. SWFtools (specifically, pdf2swf) can then be used to convert the PDF to SWF.

Since I don't use MetaPost, I don't think I'm the best person to

you could add this info to the proper page(s)? E.g. at
http://wiki.contextgarden.net/Command/startuseMPgraphic
There is an overview of the new stubs at
http://wiki.contextgarden.net/Template:MetaPost_see_also
Also: a question about
\startuseMPgraphic and
\startuniqueMPgraphic.
Both are supposed to be recompiled at every usage, so how are they
different? Actually trying it out suggests that useMPgraphic is the
only one of the two that re-evaluates its code every time; compare the
examples at
* http://wiki.contextgarden.net/Command/startuseMPgraphic and
* http://wiki.contextgarden.net/Command/startuniqueMPgraphic
But then \startuniqueMPgraphic would be the same as
\startreuseMPgraphic, so I think I'm still missing something.

mentioned somewhere in the MetaFun manual. But I agree, all these

It does make a difference when you have documents with thousands of
graphics (mkiv is much faster btw) and the pdf file is also smaller when
reuse is applied

however, during some cleanup stage something got lost ... so you need to
fix this:
\unprotect
\def\meta_use_graphic#1#2%
{\meta_begin_graphic_group{#1}%
\doifsomething{#2}{\setupMPvariables[\currentMPgraphicname][#2]}%
\getvalue{\??mpgraphic#1}%
\meta_end_graphic_group}
\protect
there are few more places where
\getvalue{\??mpgraphic ...
needs a #1 (I'll fix it).
So indeed you can have multiple independent instances. For instance we
could have one for the chemical stuff which then cannot be messed up by
other instances.

The attached file is a snapshot of the Preview window showing the pdf file generated by the following code.\starttext\startMPpagedraw unitsquare scaled 4cm dashed dashpattern (on 1cm off 1cm) ;draw unitsquare scaled 4cm shifted (5cm,0) dashed dashpattern (on 1cm) ;draw unitsquare scaled 4cm shifted (10cm,0) dashed dashpattern (off 1cm) ;setbounds currentpicture to boundingbox currentpicture enlarged 0.1cm ;\stopMPpage\stoptextYou can see, from the attached file, that the unitsquare which was supposed to appear in the middle does not show up in the Preview window. However the same file is displayed correctly in Acrobat Reader.I am not sure whether it is a context problem, or it is just a bug in Mountain Lion. I found out this issue when I saw that all the pdf files I previously generated with gnuplot context term are showing up incorrectly under the Preview after upgrading to Mountain Lion. I had to change the dash pattern in file "metapost/context/third/gnuplot/mp-gnuplot.mp", so the pdf generated by gnuplot context term can be viewed correctly with Preview under Mountain Lion.Best,Xiaoyong___ 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 ___
[NTG-context] Sequence of MetaPost Pages
When I create animations using MetaPost, I typically do something like for n=1 upto N: beginfig(n); some code endfig; endfor; and a sequence of figures are created. How can I do this in ConTeXt using \startMPpage ... \stopMPpage?

Re: [NTG-context] Sequence of MetaPost Pages
That works great. Now I have defined a global numeric
N:=8;
in \startMPinclusions ... \stopMPinclusions at the be beginning of my
document. All of my \startMPpage ... \stopMPpage environments understand
this N, but how do I reference this value as the start value for
\dostepwiserecurse? That is, I would like to do something like
\dostepwiserecurse{N}{0}{-1}{ ... some code ... }

For that, you'll need to work on the TeX end.
\edef\STEPS{8}
\dorecurse\STEPS{}
You can either use \STEPS instead of N everywhere in your code (and be
careful on how TeX code is parsed, i.e., `a := \STEPS 0` will evaluate to
`a := 80`), or use `N := \STEPS;` somewhere in the beginning of each
`\MPpage` (the `N :\ \STEPS` can be hidden behind a macro like
`\initializeAnimation`).

[NTG-context] Standalone MetaPost Graphics from ConTeXt
Is there a way to output several MetaPost PDF graphics from a single ConTeXt source file. For example, \startMPpage draw fullcircle scaled 72; \stopMPpage \startMPpage draw unitsquare scaled 72; \stopMPpage and have a separate output PDF generated for each MPpage? It seems that this ConTeXt code generates a single PDF which contains only the first graphic. I would like to have either 1) two separate PDF's with each containing their own graphic 2) a single two page PDF where each page corresponds to the appropriate graphic. Of course, the holy grail would be to be able to compile a MetaPost source file with ConTeXt.

It has to do with the fact that a page gets a topskip (by default) and it happens that this text is topskip so it gets moved down in the page builder.

It works here.
Fails here, source and log are attached.
ok, can you add this to cont-new.mkiv (after \unprotect):
\def\m_meta_colo_initializations{%
vardef OverlayLineColor=\MPcolor{\overlaylinecolor} enddef;
vardef OverlayColor=\MPcolor{\overlaycolor} enddef;
}
I have that in my local experimental code. It has to do with the fact
that mp's color spaces are not compatible with each other. As I've used
that patch for quite a while now I could probably move it to the core.
Maybe more users can test this.

Since you use it for a while it seems to work ⇒ into the core
