As the creator of a metafont one can invent an encoding, say 'ASCII CAPS AND DIGITS' which is completly unknown by the rest of the world. And I can use T1 or OT1 or what ever. To create different encodings for a font the designer has to designate a parameter or parameterfile to select that.

Metafun error
by John Culleton 22 May '03

22 May '03

Just got back into Metafun. I used the example program from page 5 of the manual: ------------------------------------------ \setupcolors[state=start] \starttext \startuseMPgraphic{dummy} fill fullcircle scaled 5cm withcolor red; \stopuseMPgraphic \useMPgraphic{dummy} \stoptext ------------------------------------------ When I run texexec test.tex I get: ----------------------------- This is MetaPost, Version 0.641 (Web2C 7.3.7x) (test-mpgraph.mp >> spotcolors >> true ! Equation cannot be performed (numeric=boolean). <to be read again> ; l.23 spotcolors := true ; --------------------------- on the second pass. If I eliminate the red color it still doesn't work. The file test-mpgraph.mp contains these lines which look ok: cmykcolors := true ; spotcolors := true ; color OverlayColor, OverlayLineColor ; If I just generate the graphic with texexec --mptex test.tex that works OK. Any ideas? -- John Culleton

A Metapost question
by Michal Kvasnicka 22 May '03

22 May '03

Good noon. I'm sorry that I bother you with an off-topic question, but I know here are many Metapost gurus. I'd like to join two point (E1 and E2) having the same ypart (ypart(E1)=ypart(E2)) with the TeX underbrace sign. To do it I have to tell TeX (via btex ... etex?) the horizontal distance of the two points. Do you know how can I do it? Many thanks, M.K.

What are the defaults? I see, that Duerer is designed only in one size. This is not always the case with metafonts. For example, I should can say things like: Use font with designsize 10pt for all the fontsizes lower and equal to 10pt and scale acoordingly. Use font with designsize 11pt for the fontsize 11pt. Use font with designsize 14.4pt for fontsizes from 12pt to infinity and scale them. What about encoding? For example, an OT1 font doesn't contains german umlauts, a T1 font does. By the way, there is also a typescript-section [special]. What can I do with this? I will report about my attempts about my font 'bunt' in a second mail. Gru�, Wolfgang

(not testet yet!) Problems: 1. The bodyfont is 12pt per default, so pdftex uses bu1200.tfm to calculate the text. The chaptertitle is then in 20.74pt, but pdftex doesn't use the existing font bu2074.tfm, but scales the bodyfont by a factor of 1.728. As a result, mktexpk calculates the pk files bu1200.600pk and bu1200.1037pk, and not bu1200.600pk and bu2074.600pk. I tried to include the commentet two lines in the typescript, because I always found written sizes in context with one digit behind the point, but the result is negativ too. 2. The log-file contains the following: > ) (./type-bunt.tex) > fonts : [calligraphy] [bunt] [name,default,ec,special] My typescript neighter contains a section [ec] nor a section [special].

Frames kill indenting of paragraphs

Hello. I am trying to put frames around some of my enumerations (which I use to typeset theorems, lemmas, etc.), but when I put a frame around the enumeration, the indenting of the paragraphs disappears. Here is some sample code: \setupoutput[pdftex] \enableregime[il1] \setuppapersize[A4][A4] \setupbodyfont[cmr,11pt] \setupspacing[packed] \setupinterlinespace[medium] \setupspacing[packed] \setupindenting[medium] \indenting[yes,next] \defineenumeration[MyEnum] [location=serried, indenting={yes,next}] \defineframedtext[MyFrame] [indenting={yes,next}] \defineframedcontent[mine] [indenting={yes,next}] \starttext \startMyEnum Does it work?\par Yes, it does!\par \stopMyEnum \startframedcontent[mine] Does it work?\par No, it does not!\par \stopframedcontent \startframedcontent[mine] \startMyEnum Does it work?\par No, it does not!\par \stopMyEnum \stopframedcontent \startMyFrame \startMyEnum Does it work?\par No, it does not!\par \stopMyEnum \stopMyFrame -- Emil Hedevang Lohse <http://home.imf.au.dk/emil/> Alle spørgsmål er lige dumme.
