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)

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);

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

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

Problem with font mapping

[Mika Ritola]

[-- Attachment #1.1: Type: text/plain, Size: 1723 bytes --]

Hello again,

I seem to be running into all sorts of font problems. Now my document has
suddenly turned bold. For example, running the following code results in
"Test." being rendered in bold characters.

\usemodule[simplefonts]
\setmainfont[Adobe Garamond Pro]

\starttext
Test.
\stoptext

Running "mtxrun --script font --list --pattern="*Garamond*" --all" reveals
that there's something fishy about the font mapping:

adobegaramondpro => agaramondprosemibold => AGaramondPro-Semibold.otf
adobegaramondprobold => agaramondprosemibold => AGaramondPro-Semibold.otf
adobegaramondprobolditalic => agaramondprosemibolditalic =>
AGaramondPro-SemiboldItalic.otf
adobegaramondproitalic => agaramondprobolditalic =>
AGaramondPro-BoldItalic.otf
adobegaramondpronormal => agaramondproregular => AGaramondPro-Regular.otf
adobegaramondproregular => agaramondprobold => AGaramondPro-Bold.otf
adobegaramondprosemibold => agaramondprosemibold =>
AGaramondPro-Semibold.otf
agaramondprobold => agaramondprobold => AGaramondPro-Bold.otf
agaramondprobolditalic => agaramondprobolditalic =>
AGaramondPro-BoldItalic.otf
agaramondproitalic => agaramondproitalic => AGaramondPro-Italic.otf
agaramondproregular => agaramondproregular => AGaramondPro-Regular.otf
agaramondprosemibold => agaramondprosemibold => AGaramondPro-Semibold.otf
agaramondprosemibolditalic => agaramondprosemibolditalic =>
AGaramondPro-SemiboldItalic.otf

As you can see, agaramond... are mapped properly while adobegaramond... are
mapped wrong.

Changing \setmainfont[Adobe Garamond Pro] to \setmainfont[agaramondpro]
fixes the issue but, still, I'd prefer to use the former (as I've done until
now) since it's clearer.

I'm running ConTeXt version 2009.11.24 10:13.

if the mappings are different, and this is the result:

adobegaramondpro => Adobe Garamond Pro Bold => AGaramondPro-Bold.otf
adobegaramondprobold => Adobe Garamond Pro Bold => AGaramondPro-Bold.otf
adobegaramondprobolditalic => Adobe Garamond Pro Bold Italic =>
AGaramondPro-BoldItalic.otf
adobegaramondproitalic => Adobe Garamond Pro Italic =>
AGaramondPro-Italic.otf
adobegaramondproregular => Adobe Garamond Pro Regular =>
AGaramondPro-Regular.otf
adobegaramondprosemibold => Adobe Garamond Pro Semibold =>
AGaramondPro-Semibold.otf
adobegaramondprosemibolditalic => Adobe Garamond Pro Semibold Italic =>
AGaramondPro-SemiboldItalic.otf
agaramondprobold => AGaramondPro-Bold => AGaramondPro-Bold.otf
agaramondprobolditalic => AGaramondPro-BoldItalic =>
AGaramondPro-BoldItalic.otf
agaramondproitalic => AGaramondPro-Italic => AGaramondPro-Italic.otf
agaramondproregular => AGaramondPro-Regular => AGaramondPro-Regular.otf
agaramondprosemibold => AGaramondPro-Semibold => AGaramondPro-Semibold.otf
agaramondprosemibolditalic => AGaramondPro-SemiboldItalic =>
AGaramondPro-SemiboldItalic.otf

In other words, the mappings seem to be fine here (though I'm not sure about
the first one). Thus, it seems that some change in ConTeXt has "broken" the
font.

the analyser has been rewritten and now let's the familyname + weight 
play a more important role and if there's something weird in there ...
in that case the (undefined) order of hashing kicks in

anyhow, i cannot check it here without fonts so someone has to buy me 
the adobe font collection first -)

Hi Alan,

I run in this myself. A possible solution is:

\startuniqueMPgraphic{test}
	for i = 0 upto 10 :
		draw thelabel(textext("\color[red]" & decimal i &""), (i, -1)  
scaled 1cm);
	endfor ;
\stopuniqueMPgraphic

\setupcolors[state=start]

\starttext
	\uniqueMPgraphic{test}
\stoptext

Yes, Thanks.
I thought of this as a work-around, but the first is clearly a bug.
What actually works is:

\setupcolors [state=start]

\starttext

\startuniqueMPgraphic{test}
	for i = 0 upto 10 :
		%draw thelabel(decimal i, (i, 0) scaled 1cm) withcolor red ;
                draw thelabel(textext("\red"& decimal i &""),
			(i, 0) scaled 1cm) ;
	endfor ;
\stopuniqueMPgraphic

\uniqueMPgraphic{test}

\stoptext


Now it is up to the experts to fix the bug in mkiv.

Alan
