Metapost and mkiv

Metapost and mkiv

[Otared Kavian]

Hi all,

The following minimal example used to work with mkiv (until last May,  
I would guess…) but now it doesn't work with the latest
ConTeXt version 2009.09.21 17:39

Can any one tell me please what am I doing wrong?

Best regards: OK
%% begin

\setupcolors[state=start]
\starttext

\startbuffer[axes-1]
numeric u ; u := .5cm ;
path xox ; xox := (-u,0)--(8u,0) ;
path yoy ; yoy := (0,-u)--(0,7u) ;
draw xox withcolor blue ;
draw yoy withcolor blue ;
\stopbuffer

This MetaPost graphic is  \doifmodeelse{mkiv}{not shown with mkiv} 
{shown with mkii}:

\placefigure[middle][-]{}{\processMPbuffer[axes-1]} {}

\stoptext


%% end

It also works for me with 2009.09.18. Do normal MP figures work (those 
inside \startMPcode...\stopMPcode)

Metapost+mpgraph and mkiv

[Alan BRASLAU]

mpgraph does not appear to work properly under mkiv.

%% minimal example %%
\starttext

\startuseMPgraphic{test}
input graph
draw begingraph(16cm,12cm);
	setrange(whatever,whatever,whatever,whatever);
	gdraw (0,0) -- (1,1) ;
	endgraph;
\stopuseMPgraphic

\startTEXpage
\useMPgraphic{test}
\stopTEXpage

\stoptext
%%%%%%%%%%%%%%%%%%%%%


Works correctly under mkii (texexec) but not under mkiv (context).

So, for the mailing list, here is a working solution (mkii & mkiv):

%% minimal example %%
\starttext

\startMPinclusions
input graph
\stopMPinclusions

\startuseMPgraphic{test}
draw begingraph(16cm,12cm);
        setrange(whatever,whatever,whatever,whatever);
        gdraw (0,0) -- (1,1) ;
        endgraph;
\stopuseMPgraphic

\startTEXpage
\useMPgraphic{test}
\stopTEXpage

\stoptext

Thanks! This works in mkiv (but appears to be broken in mkii).

Metapost+mpgraph withcolor

[Alan BRASLAU]

glabel <option list> withcolor is broken (mkiv and mkii).
The label at the first point is black (the 2nd comes out red).

%% minimal example %%
\setupcolors[state=start] 
\usemodule[graph]

\startuseMPgraphic{test}
draw begingraph(16cm,12cm);
        gdraw (0,0) -- (1,1) withcolor red ;
	glabel.urt(btex beginning etex, 0) withcolor red ; 
	glabel.llft(btex \red end etex, infinity) ; 
        endgraph;
\stopuseMPgraphic

\starttext

\startTEXpage
\useMPgraphic{test}
\stopTEXpage

\stoptext
