[NTG-context] Wrong section space after placefigure with newcolumnsets

2018-04-05 Thread Charles Vejnar 

Hi,

I am placing figures in a columnset. The next header (section, 
subsection...) following the figure has always missing vertical space.


See the normal space after "One subsection" and "Four subsection" but 
reduced space after "Two subsection" and "Three subsection" in the 
example below.


Tested with ConTeXt  ver: 2018.04.04 and LuaTeX, Version 1.07.0.

This seems to be the opposite problem as the one described recently in 
the thread "Bug in wrapped placefigure".


Any solution or fix?

Thank you very much for your help.

Charles

I thought of using vardef but that is kind of verbose because I gave to repeat
"rotated angle" three times.

\startMPpage
  vardef orbital(expr angle) =
save p ;
path p ;
p := origin .. (2,1) .. (3,0) .. (2,-1) .. (-2,1) .. (-3,0) .. (-2,-1) .. 
cycle ;
image (
  draw p scaled 6 rotated angle;
  label("\strut$+$",(+10,0) rotated angle);
  label("\strut$-$",(-10,0) rotated angle);
)
  enddef ;

  picture px, py ;
  px := orbital ( 0) ;
  py := orbital (90) ;

  draw px ;
  draw py ;

In the MWE below I would like py to be px rotated by 90 degrees but the labels
should not be rotated.  Is it possible?

Use with following code scheme in ConTeXt:

It will produce a standalone image in a pdf.

Thanks Hans for the advice.

I use a mac-mini and it seems that mupdf, of which mutools is part off, 
does not have a macOS version, or I would have to build from source. 
However it looks like I can use Inkscape with a wee bit thought to do

[NTG-context] Saving Metafun Graphic for use outside ConTeXt

2018-04-05 Thread Keith McKay 

Dear Readers,

I have been playing about with METAFUN over the last few days trying to 
get a feel for it. I was wondering if it is possible to save the 
graphics produced in a context document for use outside. On looking at 
the Metapost manual I see you can using the following commands save a 
graphic as an svg file.


/outputformat := "svg"; /

/outputtemplate := "test.svg";/

//

I have tried adding this to some MPcode in a ConteXt document but these 
lines seem to be ignored since no svg file is produced apart from the 
usual ConTeXt files. Is this expected behaviour? I have been able to get 
svg files using mpost on the command line.


Here is a minimum working example (which I'm sure could be coded more 
elegantly):


/\starttext/

//

/\startMPcode/

//

/outputformat := "svg";/

//

/outputtemplate := "test.svg";/

//

/beginfig(1)/

//

/randomseed:= uniformdeviate infinity;/

//

/path pat;/

//

/x:=uniformdeviate(5);/

//

/y:=uniformdeviate(5);/

//

/pat:=(x,y);/

//

/for i = 1 upto 5:/

//

/a:=uniformdeviate(5);/

//

/b:=uniformdeviate(5);/

//

/pat := pat...(a,b);/

//

/endfor;/

//

/pat:=pat..(0,5);/

//

/draw pat scaled 10pt;/

//

/picture pic;/

//

/pic:=currentpicture;/

//

/endfig;/

//

/\stopMPcode/

//

/\stoptext/

Best Wishes

Keith
