Re: [NTG-context] Numerical Calculations
How did you produce a video out of the PDF? I wrote a BASH script to automate this process, but essentially it involves converting each frame/page of the PDF to JPG and then combining the JPG sequence into a MP4 movie. The hypocycloid example has 191 frames, and so I did something like: let n=0; while [ $n -lt 191 ] do convert -density 720 hypocycloid.pdf[$n] -resize x720 -flatten -gravity center -extent 1280x720 -quality 100 hypocycloid-$n.jpg done ffmpeg -r 13 -i hypocycloid-%d.jpg -b 5000k -vcodec libx264 -y hypocycloid.mp4 ___ 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 ___

Hi there,
sorry for being such a pain in the neck.
Is there going to be a solution considering the spacing problems with the use
of units (native mkiv command) in near future (within 2-3 weeks)? If there is
none and I am not doing something wrong, I'll add a local work around every
time I use units. As this is much work, I'd appreciate if someone told me if
this is something that might be fixed soon. If not I'm good - I just need to
know.
Explanation of my problem: Maybe I am doing something wrong, but in the
resulting document the spacing is bigger in math mode then in the text mode in
case I use \units{...}. In particular, the distance for the decimal separator
is as if I would type $1,2$ instead of $1{,}2$ (example: $\units{1,2}$)..
can you try
\appendtoks
\disablemathpunctuation
\to \everyunits
Thanks.
Cheers,
Andreas

Hi,
I still do have problems with a wrong spacing between number and unit in math
mode (minimal example below). Clearly, I could do something like
$\alpha = $ \unit{1,2 meter}
but I think this is likely to result in problems with the look of the result in
case this is close to a line break.
Cheers,
Andreas
MINIMAL EXAMPLE
\starttext
\unit{1,2 meter} % what I would expect
$\unit{1,2 meter}$ % wrong spacing
$\unit{1{,}2 meter}$ % there is no output after 1

Hi there,
I encountered some problems with the built in units command in MKIV. I
provide a minimal example which should demonstrate my problems. Maybe I am
doing something wrong...
\setupbodyfont[pagella]
\starttext
\unit{11,1e-1 micro mol per second} \par
$\unit{11,1e-1 micro mol per second}$ \par
\unit{11,1e-1 per second} \par
\unit{11,1e-1 / second} \par
\stoptext
Don't know for the first two, but the last two should be replaced by:
\unit{11,1e-1 inverse second}
All the best.

Thanks for looking into this. The problem with the decimal separator is solved.
You made my day with just 4 commands!
Just that you know: I still observe a tiny difference in the blank space
between numbers and times symbol (\times) when comparing math mode to standard
text mode (minimal example below). AFAIK this does not make a difference. If I
find the time i might just put every unit stuff into math mode (for consistency
reasons). So my document is ready for being published (in this respect). It
just still lacks content :)
Happy holidays to all of you.
Andreas

Re: [NTG-context] Odd /externalfigure behavior
On 12/19/2012 9:38 PM, Guy Stalnaker wrote: I'm willing to give you an image, but it cannot be the images. I have edited the file and put systematically % before the /externalfigure lines then run context against the file. As I added the % the nil error shifted to the next /externalfigure. I stopped this after five times. I have confirmed, by the way, file/directory ownership with chown and privileges with chmod. They are set as they should be, so whatever is awry is not owner/privilege related. Another reason it cannot be the images is that I used context with the same document and the same images to successfully create a document. They were unchanged, to my knowledge, the next day when context started throwing the error. While it's conceivable that some agent might have modified the documents and/or my office Linux install overnight without my knowledge, that must be considered a very remote possibility. That said, I'm hard-pressed to figure out what can possibly have changed, overnight, such that context would suddenly begin throwing the errors. That is why I unlinked/relinked Dropbox. They could change something on their end. But that had no affect on the error. Nor did moving all the images that are in the document from multiple directories into one directory. There has been some cleanup of filename constructors but nor that drastic. Maybe some are (temporary) More sensitive so nil arguments but that is then an indication of some issue earlier in the chain. The comment and next one being a problem is weird.
