Based on this I can now cut out the smaller one from a fullcircle, but it still fails with two paths having controls (or maybe because of something else).

metapost fill between outlines
by Reviczky, Adam 20 Feb '11

20 Feb '11

Hi Is it possible to fill out a space between two outlines? As for an example, I'd like to draw two circles (same center, one bigger than the other) and fill out the difference. Something like the letter "O". Here's a concrete example: %%% draw (6.949220,13.046900)..controls (9.539060,13.046900) and (10.023400,10.781200)..(10.023400,8.679690) ..controls (10.023400,5.335940) and (6.949220,0.000000)..(3.234380,0.000000) ..controls (0.890625,0.000000) and (0.000000,1.886720)..(0.000000,3.828120) ..controls (0.000000,8.492190) and (3.316410,13.046900)..(6.949220,13.046900) --cycle; draw (7.488280,12.293000)..controls (4.933590,12.293000) and (1.265620,6.226560)..(1.265620,2.531250) ..controls (1.265620,1.562500) and (1.695310,0.835938)..(2.722660,0.835938) ..controls (5.230470,0.835938) and (8.972660,7.035160)..(8.972660,10.296900) ..controls (8.972660,11.269500) and (8.703120,12.293000)..(7.488280,12.293000) --cycle; %%% I want to fill out the space between these two draw lines. Is this actually possible? The only reference to this I found was on wikipedia: "Most notably, paths can have only one segment (so that regions are simply connected), (...)" (http://en.wikipedia.org/wiki/MetaPost) I thought I ask here before I put this aside. As a workaround I fill out the bigger one with color black and the smaller one with color white, but I need to put this on different background colors, so the use of this is very limited. How does it work with fonts (Metafont)? Who's filling that out, because thats also just based on outlines, right? Thanks Adam

Latest beta: Can't compile a document with lists (with no math fonts)
by Marco Pessotto 19 Feb '11

19 Feb '11

I think the same happened some time ago when the not-loading (horrible word, my english is rotting) of Latin Modern was still an experimental feature. Anyway, minimal example: %%%% start %%%% \usetypescript[libertine] \setupbodyfont[libertine,10pt] \starttext \startitemize[1] \item fail \stopitemize \stoptext %%% stop %%% It compiles just fine commenting the first 2 lines or with ConTeXt version 2011.01.26 09:01 While with the latest 2011.02.18 ! Math error: parameter \Umathquad\displaystyle is not set. system > tex > error on line 8 in file fail.tex: Math error: parameter \Umathquad\displaystyle is not set ... 1 \usetypescript[libertine] 2 \setupbodyfont[libertine,10pt] 3 4 \starttext 5 6 \startitemize[1] 7 8 >> \item fail 9 10 \stopitemize 11 12 \stoptext \mathematics ...rmalstartimath #1\normalstopimath \fi \dodosymbol ...bol \csname \??ss :#1:#2\endcsname \relax }\relax \donormalsymbol ...bol \redosymbol \currentsymbol \fi \fi \dodosymbol ...bol \csname \??ss :#1:#2\endcsname \relax }\relax \donormalsymbol ...bol \redosymbol \currentsymbol \fi \fi <to be read again> } ... l.8 \item f ail ? Sorry, but I can't typeset math unless various parameters have been set. This is normally done by loading special math fonts into the math family slots. Your font set is lacking at least the parameter mentioned earlier. Best wishes -- Marco

Re: [NTG-context] EPUB workflow from ConTeXt source?
by Mica Semrick 19 Feb '11

19 Feb '11

Have you considered authoring in something besides context? Say TEI XML or Docbook, or even markdown (if possible)? If markdown is suitable, then you can end up with both epub and context at the end. Or if using TEI or docbook, you can write a map file (something I have been trying to do) and typeset the xml file directly with context. I'm always happier knowing that I can get as many different output types from a single source as possible.
