[NTG-context] Mail troubles
Hi, I just want to let everybody know that I am experiencing problems with email delivery since monday morning around 8 a.m. Hopefully, everything should return to normal during the day. I'm writing this because chances are that I've missed some mail addressed to me, esp. private off-list email. If you expect me to answer to something you sent, it is probably wisest to re-send it. Greetings, Taco ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context
Re: [NTG-context] Clipping a path to a boundary --- Being more specific
Hans et al, I think I've found something that works. I know ahead of time that there will only be two crossings of the clipping path boundary (I make sure of the by the parameters I choose): beginfig(0); % initialize a, h, and h for f(x)=ax^2+bx+c=a(x-h)^2+k numeric a, h, k; a=-1; h=-3; k=2; % initialize scale numeric u; 10u=3in; % draw grid for k=-5u step 1u until 5u: draw (-5u,k)--(5u,k) withcolor 0.85white; draw (k,-5u)--(k,5u) withcolor 0.85white; endfor; % draw axes drawarrow (-5u,0)--(5u,0); drawarrow (0,-5u)--(0,5u); % label axes label.rt(btex $x$ etex, (5.2u,0)); label.top(btex $y$ etex, (0,5.2.u)); label.bot(btex $5$ etex, (5u,0)); label.lft(btex $5$ etex, (0,5u)); % define function f(x)=a|x-b|+c vardef f(expr x)= a*(x-h)*(x-h)+k enddef; % draw line with given point and slope path F; F:=(-6,f(-6)); for x=-6 step .1 until 6: F:=F--(x,f(x)); endfor; % the line F:=F scaled 1u; % clipping path path cpath; cpath:=(-5,-5)--(5,-5)--(5,5)--(-5,5)--cycle; cpath:=cpath scaled 1u; % clip the path F pair A, B; F:=F cutbefore cpath; F:=reverse F; F:=F cutbefore cpath; drawdblarrow F; endfig; end. ___ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context

Both were present in the example. I've created a collector item
for this. (which means that I believe it really is a bug :-))

You get pretty different results depending on what you write to
\setupcolors[conversion=yes/no/always,reduction=yes/no,rgb=yes/no,cmyk=yes/no,mpcmyk=yes/no]
but I don't know what exactly they mean. The example in the manual
with \MPcolor{cmyyellow} doesn't seem to be proper cmyk kind of
yellow (c=0.08,m=0,y=0.89,k=0), so Hans probably used a set of setups
which handles the .5\MPcolor{cmyyellow} the same way as if it was an
rgb yellow.
Does \setupcolors[cmyk=no] suit your needs? However, you have to be
aware that your cmyyellow won't be y=1 any more, but the yellow
mentioned above.
Your example results in a color that is (c=.68,m=.71,y=.64,k=.86), so
it is still a kind of OK mixing, but the computer doesn't know in
which way you would like the colors to be mixed.
An alternative (for brighter colors in this case) is to write
.5[\MPcolor{cmyyellow},\MPcolor{cmywhite}]
if you define cmykwhite to be something like
\definecolor[cmywhite][y=0.1]
What I don't understand is why
\definecolor[cmywhite][c=0,y=0,m=0,k=0]
is converted to black (even a warning is issued).

[NTG-context] A wee bit more about OpenType (Myriad Pro)
Greetings all Adam, Having successfully installed Jenson Minion Pro I've been trying to get Myriad Pro to install as a companion Sans (motivated in part by the fact that Adam has a nice typescript file for Warnock Pro with Myriad). I'm having some difficulties, which seem similar to difficulties I had earlier on…but apparently we finished our conversation off the list, so I can't locate what the solution was ;) (I believe it was try updating to the latest version of LCDF from *EXPERIMENTAL*). Before I display some error messages, I want to ask, Adam, why the Myriad Pro fontsynonyms in your typescript do not have any of the OpenType features—liga? kern? Is this due to Myriad Pro's particulars? [I've just checked, and it isn't only Myriad Pro that won't install.] I'm using Gerben's i-Installer, 2004 stable, ConTeXt updater, LCDF 2.26 (no longer in the experimental directory). I've also tried with the 2005 development set. The result is the same.

indeed, i use slightly different red/yellow in the metafun manual -)
but i'm not sure if that is the problem here

Both were present in the example. I've created a collector item
for this. (which means that I believe it really is a bug :-))
I tried
\definecolor[cmyyellow][y=1]
\definecolor[cmycyan][c=1]
and then .5[\MPcolor{cmycyan},\MPcolor{cmyyellow}]
Without the cmyk=no option, color mixing really works wrong (I get
yellow instead of green, perhaps c=.5,y=.5 would be something to
expect), but with it, my Acrobat states that the colors are not proper
cyan and yellow any more (but the exact numbers probably depend on
settings for cmky-rgb-cmyk conversion).
Well, the best conversion ever seen was the one by MS Word (when I
tried to include a cmyk pdf image into a document): blue became green,
red resulted in blue and yellow in pink ;)
About the problem of white cmyk color
(\definecolor[colorname][c=0,m=0,y=0,k=0]): I guess that the problem
could lie in the \doifelse loop(s) of \dododefinecolor in
colo-ini.tex. The loop simply checks if any color component is
different from zero and chooses the first suitable color space. CMYK
white is probably the only exception to this rule.
What about deciding about the color system on the basis of settings
used (r=0 = rgb or c=0 = cmy(k) or ...), before executing this
(modified) loop? Or perhaps having some predefined zero colors
(cmykwhite for example)? An usual rgb white can be used, but I'm not
sure if it can be properly mixed with cmyk colors then.

look in mp-spec how cmyk is defined and you'll see why it gets messed up ... cmyk expands to a special directive and .5 scales that one, if needed i can make a scale macro

scaling of cmykcolors does not work when cmykcolors i sset to true; this is
because i used colors as signals for the postprocessor and in this case the
postprocessor code gets scaled and is no longer recognizable as such and
therefore it's treates as a normal color
tricky stuff
a solution is to define the 50% color beforehand

[NTG-context] \Shaped macro in MetaFun manual
The third line in the page 145 in the MetaFun manual (metafun-p.pdf)
says
The \Shaped macro was defined as:
some \inframed[background=Shape]{text} with a frame ...
some \Shaped{text} with a frame ...
It seems to be a typo. Let me know the exact definition of \Shaped
macro.
Thanks in advance.
Best, ChoF.
