Re: [NTG-context] Color rendering & transparency with metapost
Thank Luigi for your response, the problem is that the background color rendering isn't the same if you comment out or not the following line : draw fullcircle scaled 10cm shifted (0cm,0.25*\overlayheight) withcolor transparent(1,0.5,white) withpen pencircle scaled 2cm; After some experiments, the problem is solved ( hence not understood ???) using rgb=no in setupcolors... It's maybe a viewer-centric problem : I use acroread 8.1.2 under linux.

[NTG-context] Color rendering & transparency with metapost
Hi,
I have some trouble using a gradient background (solid) with a
transparent element :
\startMPinclusions
def test_shade (expr a, b) =
pickup pencircle scaled 1mm ;
color ca ; ca := \MPcolor{a} ;
color cb ; cb := \MPcolor{b} ;
color cc ; cc := \MPcolor{c} ;
sh := define_linear_shade(origin
shifted(0cm,.5*\overlayheight),origin,ca,cb) ;
fill fullsquare xscaled \overlaywidth yscaled \overlayheight
withshade sh;
draw origin withcolor cc;
draw origin shifted(0cm,-.25*\overlayheight) withcolor cc;
enddef ;
\stopMPinclusions
\setupcolors[state=start]
\definecolor[a][r=.57254902,g=.784313725,b=.917647059]
\definecolor[b][white]
\definecolor[c][darkred]
\starttext
\defineoverlay[bgoverlay][\uniqueMPgraphic{bg_top_shade}]
\setupbackgrounds[page][background=bgoverlay]
\startuniqueMPgraphic{bg_top_shade}
test_shade(origin, origin shifted(0cm,1cm));
draw fullcircle scaled 10cm shifted (0cm,0.25*\overlayheight)
withcolor transparent(1,0.5,white) withpen pencircle scaled 2cm;
If you comment out the previous line the color rendering is
definitelly different...
\stopuniqueMPgraphic
\input knuth
\stoptext
I have searched the ML without success, any idea ?

Renaud

Re: [NTG-context] ctx files
After giving it some further thought, I tried the following (which seems
more logical) but that doesn't work either...
*** ctx-test.tex ***
\starttext
\doifmode{mode1a}
{mode1a}
\doifmode{mode2a}
{\blank mode2a}
\stoptext
*** ctx-main.ctx ***
*** ctx-flags.ctx ***
texengine=luatex
interface=en
result=ctx-modes
*** ctx-modes1.ctx ***
mode1a
*** ctx-modes2.ctx ***
mode2a
*** end of code ***
A Google search for the XML include element didn't bring much wisdom either.
What's missing/wrong please ?

1. Why don't you use the itemize environment?
2. End the paragraph before the end of the group.
\item 2 test 2 \par

[NTG-context] \item doesn't work with ConTeXt (works with LuaTeX/TeX)
Hi,
I have a strange error with ConTeXt. This error isn't produced using
LuaTeX. The error seems to be in one of the CoTeXt files but I can't
understand it. I hope some of you will be able to help me there.
The code is as simple as that:
= test.tex =
1 \begingroup
2 \item{1} test 1
3 \item{2} test 2
4 \endgroup
5
6 \end
7
Now, if I run 'context test', I get at some point the following error:
! Missing } inserted.
}
\endgroup
\stopitemgroup ...mdepth }\egroup \else \endgroup
\global \advance \itemdept...
l.5
?
Attached, the complete log.
I hope you'll be able to understand that strange error.
Thanks.
Mildred
