bug in mplib?

bug in mplib?

[Thomas A. Schmitz]

Hi all,

I just noticed that with the new incarnation of metapost, arrows  
behave somewhat erratically. Take this minmal example:

\starttext

\startuseMPgraphic{arrowtest}
z1=(0,0) ;
z2=(3cm,0) ;
ahlength := 15pt ;
pickup pencircle scaled 5pt ;
drawarrow z1--z2 ;
\stopuseMPgraphic

\useMPgraphic{arrowtest}

\stoptext

compile it with mkii and mkiv and observe the difference.

All best

Thomas

same here. another broken example

\starttext

\startuseMPgraphic{squaretest}
   draw unitsquare xyscaled(5cm,2.5cm)
   withpen pensquare scaled 4;
\stopuseMPgraphic

\useMPgraphic{squaretest}

\stoptext


and sorry, i promised to test. but currently i'm stuck with the adaption 
of my mp specials... still trying to understand the code. without those 
specials, my examples won't work (so no testing from my side).

best wishes, peter

could be related with thomas's bug, more news later

(fyi: the conversion is now using more low level mp output, and we have 
to figure out what happens there)

For linux, I get metapost 1.005 and luatex 0.28.0-2008070423 and my test 
file as well as the actual file compile correctly.

At the moment both Metapost 1.008 and LuaTeX with sockets (only for
ppc) compilations are broken on Mac, so it might be difficult to
update :(

[well, Aditya is on linux, but still]

Hi,

I get different results when I compile the following file using mkii and 
mkiv. See the attached pdf output. I am using (I know, I need to update)

mpost -v = MetaPost 1.005 (Web2C 7.5.5)
context --version = 2008.06.22 17:38


\setupcolors [state=start]
\starttext

\startMPpage

   z.1 = (-1cm, 0) ;
   z.2 = ( 1cm, 0) ;
   z.3 = (0, -1cm) ;
   z.4 = (0,  1cm) ;

   path p[] ;

   p.1 := z.1 -- z.2 ;
   p.2 := z.3 -- z.4 ;

   draw p.1 ;

   draw p.2 withpen pencircle scaled 3bp withcolor white ;
   draw p.2 ;

\stopMPpage

\stoptext
