ConTeXt logo

ConTeXt logo

[Thomas A. Schmitz]

All (and especially Hans...),

where is \CONTEXT (the logo) defined? Looking at the output I get, I  
wonder if it doesn't need a bit of kerning between Con and the  
following T; there's quite a gap between these two letters (at least  
in the font I'm using).

Thanks and all best

Thomas

Have a look at \ConTeXt in cont-log.tex. The needed spacing  will vary
per font family, of course.

Usually (as for the NTG's journal), we do not even try to get it right.
Our defs are along these lines:

   \def\ConTeXt{Con{\TeX}t}
   \def\LaTeX{La\TeX}
   \def\MF{Metafont}
   \def\MP{Metapost}

etc. (basically, only use the \TeX macro and ignore all else)


Cheers, Taco

Wonderful, thanks Taco! I see that somebody had played around with  
kerning the \TeX-part, there was a commented line. I tried a somewhat  
higher value than the default 0.667em, and it seems to be looking  
better now!

Best

ConTeXt T-shirts?

[Xan]

Hi,

Do you have any cafepress/spreadshirt acount for selling t-shirts, tea 
cups, etc.?
I think it could be useful for "fans" of ConTeXt.

Thanks in advance,
Xan

No, but I have a pile of please-send-me-asap "I LOVE ConTeXt" T-shirts
from the last conference (sorry, I keep sending them for at least a
decade already) and there are still some spare ones. If you want one,
let me know.

1)Yes, I'm interested, but give me more details.
What sizes are avaliable? Prices? Colors? Men/Woman? ....

I googled it but I just found the design 
[http://www.ntg.nl/pipermail/ntg-context/2008/035005.html].



2) Another related question is what is the license of the ConTeXt 
official logo and what is it. Is it the logo that appears in the wiki 
[http://wiki.contextgarden.net/skins/common/images/logo-alt4.png] or is 
it simply the graphics of typing "Con\TeX{t}" ? Depending what are the 
license of this logo, I or any other person could open 
Spreadshirt/cafepress for other people could receive T-shirts with 
"only" ConTeXt logo (without "I love" ;-)).

I suppose that "ConTeXt" graphics is public domain, as anyone could have 
it typing only Con\TeXt and we have freedom speach. But the cicle 
ConTeXt image is another thing.  Following 
[http://www.pragma-ade.com/general/manuals/mreadme.pdf], the 
documentation and code have specific licenses but nothing is know about 
logos and trademarks.

Can you answer?

2.5) Note: this is not my intention to register an official shop without 
your permision, obviously.

3) For the other hand, I'm interested in you having shop in 
spreadshirt/cafepress and if you are insterested in the idea, I could 
help you. I think this good for the both parts: ConTeXt users and Pragma 
ADE. For one hand, user could have (not only) t-shirts with ConTeXt logo 
and Pragma ADE could join money. And last, we promote the knowledge 
about not all in the world is LaTeX ;-)

If you are insterested, I could register in spreadshirt or cafepress and 
being person in charge of that. Well, better co-"person in charge", 
because I believe best to have one "elder" context person with me ;-) 
But for the other hand I think I'm not the most appropiate for doing 
that because at least Spreadshirt ask for enterprise number, bank 
account for join money, ... data that I think it's Pragma ADE private data.

Spreadshirt is best for europe and cafepress for US.


With my best intentions,
Xan.

Hi Xan,

Most of these questions should be answered by Mojca, I guess, but:

There is not really an official logo, but I think there are three
things most people will likely recognize:

  * The word ConTeXt typeset in antykwa torunska, as in Mojca's T-shirts
  * The ConTeXt logo in the koeielogo font:
      \usesymbols[cow] \symbol[CowConTeXt] % IIRC
  * The blue traffic sign from the wiki.
    I have an mp file for that, which is attached.


Best wishes,
Taco

It does not works for me. I hadn't koeielogo font. Even when I install 
context-nonfree (in ubuntu hardy) it does not works for me.

For the other hand, because it's simply pdf file resulting processing 
text file, I suppose it has public domain license. Is there any 
legal-aid lawyer?
For the other hand, is there any trademark of ConTeXt? TeX is a 
registred trademark (as we could read in en.wikipedia). Perhaps Hans 
could answer that?.

It does not work for me too. When I run texexec or mpost (following the 
first page of metafun manual) I get the following error:
This is MetaPost, Version 0.993 (Web2C 7.5.6)

                               withcolor textcolor;

What's happen?

What is the license of this file, Taco?

I hope Mojca, or someone else, could answer the other questions.

Thanks a lot,
Xan.

You can use \startMPenvironment[global]

then you do not need to repeat this.

With [global] the environment is applied to both the MP file and the TeX 
file.

Without "\bf" at the end, I get letters more bold.
Is it not the contrary of natural behaviour? 8-|

What do you mean, the background is already transparent.

Wolfgang, when I run texexec prova.tex I obtain prova.pdf and 
prova-mpgraph.1 Both files have background white and not transparent 
background. I don't know how explain it.

Perhaps this 
[http://www.mediacollege.com/adobe/photoshop/transparent/background.html] 
could help you (?).

How do you mean that it's already transparent?

Eh? Green? I think in transparent. I transform your logo.pdf with GIMP 
and applying transparency in green color. The result I save as png file 
(gimp says me that eps does not support transparency!? is it true?).

Please, see the png file and see that background is transparent.

Dunno about eps but AFAIK postscript 3(?) supports transparent colors.

Eh? Can you explain with more details this fact?. I see green the

How do you pass from pdf to postscript?.
When I run texexec prova.tex I get prova-mpgraph.1 that file says me 
that it's eps. How can I pass from this file to transparent postscript? 
or from pdf to postscript?

In theory if postscript support transparent background, eps should do (?)

Let me explain this on a example.

\setupcolors[state=start]
\starttext
\externalfigure[contextlogo.png][frame=on]
\page
\setupbackgrounds[page][background=color,backgroundcolor=red]
\externalfigure[contextlogo.png][frame=on]
\stoptext

You can on the first page the background of the picture is white,
to show the site of the picture I enabled the frame. On the second
page I set a background color for the entire page and as you can
see the background of the picture around the circle has the same
color as the page background, this could only happen because the
background of the picture is transparent. If you go now back on
the first page you can now see, the white background is not from
the picture but from the page background.

Dou you need the eps generated or can you also use the pdf generated
from ConTeXt with the included metapost graphic.

Yes, Wolfgang. Now I understand it.
The actually process is:
texexec prova.tex --> prova.pdf and prova-mpgraph.1 (eps file) generated.

Try your code for prova.pdf:
\setupcolors[state=start]
\starttext
\externalfigure[prova.pdf][frame=on]
\page
\setupbackgrounds[page][background=color,backgroundcolor=red]
\externalfigure[prova.pdf][frame=on]
\stoptext

and I see what you said.
So it has transparent background, but why gimp says that eps does not 
support transparency? Strange. Really strange.

Size? The size of the font: the same. But more bold.If you see wiki logo 
have letters more bold than our pdf logo (see attachments)

AFAIU, trasparency is implemented using specials in mp code, so the eps 
(the .1 file) does not contain transparency, but the pdf does. Did you 
open the pdf or the eps file in gimp?

Aditya, when I open pdf or eps file in gimp, gimp pop-up a windows of 
convert the file. When the conversion is completed, it puts white 
background in the image. So I can't see if pdf has _really_ transparent 
background.

At least in older versions of (E)PS you cannot use "transparent blue"
or "transparent red" to fill shapes for example. But the background is
always transparent even in PostScript in the sense that unless you
explicitely paint the background with white, you can include your
image in another document and you won't see any white white
rectangular border around it.

GIMP doesn't really support EPS. I don't know what you need GIMP for,
but when I need to convert some EPS or PDF image into transparent PNG,
I do:

gs -dSAFER -dBATCH -dNOPAUSE \
  -sDEVICE=pngalpha \
  -dTextAlphaBits=4 \
  -dGraphicsAlphaBits=4 \
  -sOutputFile=converted_file.png \
  -r100.0 \ (put here whatever number you want)
  original_file.pdf

You can try that with the logo and you'll notice the transparent
background with GIMP.

Thanks Mojca for this script. I did the same with gimp with more more 
effort (open eps file, gimp says that it should convert, then a file 
with white background appears and then I substitute white background 
with transparent background, and save as png file. Uf!!).

Mojca, how is this script for converting pdf file to (newest) eps? For 
seeing if newest eps supports transparency.

This has nothing to do with 'newest eps'. It is to do with the appalling
support for the eps format in the gimp. Eps has had transparant
backgrounds since day one (a whole quarter-century ago).
