color conversion causes error with MPgraphic

color conversion causes error with MPgraphic

[Steffen Wolfrum]

Hi,

when I run this example ...


\setupcolors[state=stop,conversion=never]%needed for specific reason in project

\startuseMPgraphic{Test}
z1  = (-233,0) ;
z2  = (-220,22) ;
fill z1 for i=2 upto 2: .. z[i] endfor .. z1 & cycle ;
\stopuseMPgraphic

\defineoverlay[TTest] [\leftaligned {\scale[height=\overlayheight]{\useMPgraphic{Test}}}]

\starttext

\framedtext[frame=off,loffset=1em,roffset=1em,background=TTest]{\input knuth\par}

\setupTABLE[frame=off,offset=1ex]
\setupTABLE[row][each][align={middle,lohi}]
\bTABLE
 \bTR
   \bTD[nr=3,background=TTest] drei \eTD

... I get this error:

The problem is the usage of "conversion=never" ... but I need this for other reason in my project.

Any help?

Re: color conversion causes error with MPgraphic

[rvhassel]

Hello Steffen,


have you ever tried the context version of TeXLive 2011 and
than the updated version of it? There is made use of an updated
version of luatex. With that version I have fewer problems with for
instance TikZ. The stable version and the beta version of context
both use an old version of luatex ( beta-0.70.1-2011052008).
There is some luatex  version beta-0.70.1-201106.......??
Here at my work I cann't try your example, because I have
here the context version of Ubuntu and that processes with
the old version of luatex,


Kind Regards,


Rene'

Hans, does version beta-0.70.1-201106... fix the color conversion clash?
As I do not now the background I can't decide wether it is recommended to compile this version ...

Perhaps you are talking about that one that comes with TexLive2011:

This is LuaTeX, Version beta-0.70.1-2011061416 (rev 4277)

but the revision is the same of the standalone's one , so they should be
equal.

Re: Fwd: color conversion causes error with MPgraphic

[rvhassel]

Hello luigi,


indeed the ConTeXt version 2011.05.18 18:04, with the LuaTeX
version beta-0.70.1-201106141  is used in TeXLive2011. These versions
give me fewer problems with TikZ than the version beta-0.70.1-2011052008
of LuaTeX, with the same ConTeXt version.
For instance, frames are put over each other in the stable and the beta
version of ConTeXt. But with the TeXLive2011 version, these frames are nice
separated of each other and I have no problems with error messages
about "catcode". With the stable and the beta version of ConTeXt the
process stops with error messages about "catcode".
And till now I have no problems with the colors.
Is there somewhere a howto, which describes how to compile
something from svn? I have never done such a thing,


Kind Regards,


Rene'

ah yes, but it can be a problem with mkiv and or tikz, while luatex is
still the same.

The svn server is public
http://foundry.supelec.fr/gf/project/luatex/


On a linux box with svn installed, to compiled the latest trunk
$> /opt/luatex/svn
$>cd  /opt/luatex/svn
$> svn checkout http://foundry.supelec.fr/svn/luatex/trunk
$>cd /opt/luatex/svn/trunk; bash build.sh

The luatex exec. is into the build/texk/web2c folder
(i.e. /opt/luatex/svn/trunk/build/texk/web2c).

Once you've replaced the standard luatex with the last one, you must rebuild
the format and the databases
$>mtxrun --make; mtxrun --generate

There is a very nice howto written by Patrick.

@Patrick: do you remember the URL?

afaik it's unrelated to the binary ... mp by design has incompatible 
color spaces .. the latest beta should work (and on my machine I have a 
variant that uses a different trick which I want to test for a while 
first)

No, I don't even remember writing something like that (but I don't deny it either).

Hello Luigi, Stephen and Patrick,


thanks for your reactions.
At home I tried to process the example (08-01-2012) of Stephen with the
TeXLive2011 version of context, but I got the same errors as the stable and
the beta version of context. Thanks for the report of how to compile 
something
with svn.
Which person will ever buy  "Hans's"-keyboard, that of
http://www.artlebedev.com/everything/optimus/popularis
almost 10 euro for each key. I like it to give my lectures at a 
blackboard with
chalk. At the blackboard I  design my own keys, infinitely many,


Kind Regards,


Rene'

They also offer a full-size keyboard: Optimus Maximus
(http://www.amazon.de/getDigital-de-Optimus-Maximus/dp/B001M44ZB8/ref=sr_1_10?ie=UTF8&qid=1326183660&sr=8-10)

At amazon.de this is tagged	"EUR 1.804,00 (EUR 902,00 / kg)":

Now, what's more cost-efficient ... 10 euro for each key or 902 euro for each kilo?  ;o)

Congratulations! I thought I was the only one left to do that. PPCHTeX is great, but drawing biochemical formula live, with a piece of chalk, is (even) more challenging, more fun -- and better for the students.

Cheers, Jörg

ah, that kind of crap .. they introduced that in all dutch schools .. 
real interesting to see how this 1024x768 resolution works out in the 
back of the room, esp when publishers of stuff use some 30% of the 
available space for useless borders and such .. and of course such 
boards need to be compensated with special (paper based) programs to aid 
those with reading problems

(I've heard of cases where very young kids had to start wearing glasses).

I wonder how this would work out: 
http://www.3noobs.com/microsoft-surface-2-0-as-samsung-sur40-specs-price/

(Ok, off topic, but to some extent it can influence user interfaces, 
editing and proofing in the future.)

It might pay back when editing multiple scripts (now I always have to 
mess with numbers). And I would buy one if I had the money, of course 
because of those scripts, but also because this kind of adaptive stuff 
is the future. I guess it needs a company like logitech or so to make it 
cheap and large scale.

Re: Fwd: color conversion causes error with MPgraphic

[rvhassel]

Hello schoolboard and keyboard members,


such a thing like the microsoft table
http://www.3noobs.com/microsoft-surface-2-0-as-samsung-sur40-specs-price/
I had always in mind, but than a little bit smaller. I did not know
that they exist. It looks me nice that you can stay or sit before a public,
with your face to the public, and that you can write with your fingers, 
while
that is projected at a great screen behind you.
I have done such a thing with a tablet of wacom. But the students became
sea-sick of the scrolling. In certain sense you need 2-3 screens, such that
old results are visible, such that there is no need to scroll.
I don't like powerpoint! I have always the idea that people are reading
their powerpoint sheets to us, because of the fact that we can not read or
something like that. And an electronic schoolboard is a little bit to 
small, or
you need two or three of these schoolboards and that becomes too expensive.
But the problem is also that students do not write anything on paper.
Notes are not made any more.
They sit and listen ( that is what you hope they do!) and think 
everything will be
set at the internet, the lecture (video-college) and everything what is 
written will
be downloaded.

With ConTeXt I would prepare pages, where notes can be written down.
So that you can annotate pdf-files or something like that.
So staying before some screen, you call a certain page, which
is may be prepared with a heading or something like that and then
you write your notes and save it. Nowadays I use xournal to write
Lecture-Journals at the internet, that because of the fact that formulas
are easier written by hand than that you have to code them at a
certain way. But I will never call such a formula at the screen and
than tell to the people what they have to read. I want to keep
writing, just as is said by somebody else, just for the fun and
to keep the attention of the students.

And it is easy to run animations, such tables.

That is also the reason that I like it to prepare interactive pdf-files.
It is time, I have to give some lectures,


Kind Regards,


Rene'

idea for a ConTeXt keyboard

[rvhassel]

Hello Hans,


just back from the lecture I have given and I got an idea:
Take not that keyboard of you, but take the
Maximus (1430 euro!) or the Tactus, see
http://www.artlebedev.com/everything/optimus/aux/

Prepare with ConTeXt a number of keys, for instance parts
of mathematical formulas and functions, or
parts of molecules out of the chemistry.
Put them in the keys of one the keyboards, mentioned
above and there can be given a lecture with readable
formulas. By touching those keys you get a nice written
text. Or some key, that you get a nice table ( prepared
by ConTeXt) at the screen. And such that it can be filled
by handwritten information, using some tablet or
otherwise.
May be it is already possible for a virtual keyboard
on a touchscreen or something like that. A ConTeXt
package for the preparation of the keys of a virtual
keyboard?

It is just an idea, really I have no idea how to realize it,


Kind Regards,


Rene'

At least for formulae, it would probably be cheaper and more flexible
to use a graphics tablet or tablet computer, and something like the
Freehand Formula Entry System: http://research.cs.queensu.ca/drl/ffes/
. There is also http://jequation.sourceforge.net/ and JMathNotes (
http://page.mi.fu-berlin.de/tapia/projects.php , near bottom of page),
though I haven't tried any of them.

Thank you Philipp and Luigi,


never seen these applications. They are very nice.
Such applications would be nice by giving lectures,
"Web Equation"
http://webdemo.visionobjects.com/equation.html
  is much better than my idea,
