Thank you! I will wikify the examples with an explanation on the

without explanation on their exact syntax and use cases.

[NTG-context] Solution to a "superscript" problem?
Hello,
I've been trying to come up with a few methods to add definitions to
text with the help of the metafun and context manuals. The first method
adds the definition as sort of a "superscript" on top of the word, and
the second one marks multiple words with a curly bracket and adds the
definition on top of the tip of the bracket.
Here is the (ugly and hackish) code:
\startuniqueMPgraphic{defline}
path p; p:=(0,0)..controls (0,1) and (1,1)..(1,1)--(6,1)..controls(7,1)
and (7,1)..(7,2)--(7,2)..controls(7,1) and
(7,1)..(8,1)--(13,1)..controls(13,1) and (14,1)..(14,0);
draw (0,0)--(0,12pt) withcolor white;
draw p xscaled (\overlaywidth/15) yscaled 5 shifted (0,9mm) withpen
pencircle scaled 0.25mm withcolor red;
\stopuniqueMPgraphic
\defineoverlay[curlybracket][\includeMPgraphic{defline}]
\def\sentencedef[#1][#2]{\setbox\scratchbox=\hbox{#2}\hbox to
\the\wd\scratchbox{\cbox{\hbox{\tfxx\color[red]
#1}\\\hbox{\framed[background=curlybracket,frame=off]{#2}
\def\worddef[#1][#2]{\setbox\scratchbox=\hbox{#2}\hbox to
\the\wd\scratchbox{\cbox{\hbox{\rotate[rotation=25]{\tfxx\color[red]
#1}}\\\hbox{#2
\starttext
\hbox{\worddef[def1][Lorem] ipsum \worddef[def2][dolor] sit
\worddef[def3][amet] consectetur \worddef[def4][adipiscing] elit.}
\hbox{\sentencedef[def5][Lorem ipsum] dolor sit \sentencedef[def6][amet
consectetur] adipiscing elit.}
\stoptext
I haven't figured a way to add the curly bracket graphic neatly nor
position the definition correctly on top of it.
I would be very interested in any advice regarding these two functions
and how to rewrite both of them in a more elegant way.
Best regards,

[NTG-context] Visual debugging
Hi, I'm in a need for more visual debugging aids. I tried the supp-vis module, but it did not give enough cues. I guess the ruledhbox is bound by ascender and descender height vertically, but I'd like to see also the cap height and x-height lines. Is it possible?

[NTG-context] Clip and framed not precise in MKIV
Hi,
I've used ConTeXt to chop up a big map svg on separate A4 papers like
this:
\setuplayout[width=190mm,backspace=10mm,height=297mm,topspace=10mm,
header=0mm]
\setupclipping[nx=3,ny=3]
\starttext

\dorecurse{3}{\framed{\clip[x=\recurselevel,y=3]{\externalfigure[map.svg][width=570mm]}}}
\stoptext
I'm using framed to indicate where the pieces should be cut. The
problem is that \framed does not
frame the area produced by \clip precisely. There is a small gap
between the frame border and
the clipped image area and the gap is of different size on the left and
right sizes than
for example on the bottom.
Am I overlooking some default setting? Shouldn't \framed frame the
object inside it without
leaving a padding between them?

[NTG-context] IPA symbols in MKIV
Hello, I'm having a trouble getting IPA symbols to show up with MKIV. I've read through the old threads about using IPA, and it seems there is no module like tipa for ConTeXt for easy input. I've tried also using SIL Gentium as the main font and entering the IPA symbols directly as UTF-8, but only a part of them will render (even though they all exist in the actual font in the right plane and are viewable in other programs). Almost none of the diacritics render. \definetypeface [MyFace][rm][serif][gentium][default][encoding=uc] \setupbodyfont[MyFace, 11pt] \starttext n̥ d̥ ̊ɭ˔ ʎ̥˔ \stoptext only n, d and ̊ will render in the PDF. In other apps using Gentium all the glyphs are visible. Is there a way to output IPA symbols correctly (when they are entered as UTF-8), or would it be possible to introduce a macro/module with an environment like \startipa \stopipa and commands for entering the symbols inside the environment? Entering some of the symbols correctly (such as velarized or pharyngealized diacritics which should appear on top of the letter) is hard when done directly with Unicode, so at least TeX-like shorthands for all the symbols and diacritics would really be appreciated.

Re: [NTG-context] MKIV strange results in Adobe Reader
Hi,
I have now investigated the color errors in Adobe Reader further.
I produced a test PDF without simpleslides with MKIV (mtx-context |
current version: 2011.09.10 12:55).
Here is the source:
\language[fi]
\setupcolors[rgb]
\usemodule[metafun]
\setupbackgrounds[page][background=color,backgroundcolor=black]
\startreusableMPgraphic{variympyrat}
vardef ColorCircle (expr method, factor, ca, cb, cc) =
save u, p ; path p ; p := fullcircle shifted (1/4,0);
image (fill p rotated 90 withcolor transparent(method,factor,ca); fill
p rotated 210 withcolor transparent(method,factor,cb); fill p rotated
330 withcolor transparent(method,factor,cc))
enddef;
draw ColorCircle ("normal", 1, cyan, magenta, yellow) xsized 6cm;
draw ColorCircle ("darken", .85, cyan, magenta, yellow) xsized 6cm;
currentpicture := currentpicture shifted (0,-6cm);
draw ColorCircle ("exclusion", 1, red, green, blue) xsized 6cm;
\stopreusableMPgraphic
\starttext

\title{metafun}
\includeMPgraphic{variympyrat}
\title{svg}
\externalfigure[variympyrat.svg]
\title{png}
\externalfigure[variympyrat.png]
\stoptext
and here is the output:
https://pi-xi.net/share/context_reader_test.png
https://pi-xi.net/share/context_reader_test.pdf
You can also see the original files used in the test here:
https://pi-xi.net/share/variympyrat.png
https://pi-xi.net/share/variympyrat.svg
The gray background effect happens randomly even with only using svg
images straight from inkscape.
When using png images, I noticed it happens more often when there are
multiple layers in the png.
With metafun graphics, the image colors are messed up in addition to
the gray background.
I would like to know:
a) How to avoid it with metafun, png AND svg graphics?
b) What is the cause (Adobe reader bugs? Errors in my source? Erroneous
image files? ConTeXt bug?)
Best regards,
Otso Helenius

[NTG-context] MKIV strange results in Adobe Reader
Hello, I recently made a SimpleSlides presentation with MKIV (2011.08.27 13:24). It looks ok on numerous PDF readers including Okular, Google Docs, Sumatra PDF. Whenever I open it on Adobe Reader, the results are rather puzzling: 1) The fifth page background is not black but grey, also some later pages have grey background 2) The RGB and CMYK swatch colours are all messed up The picture on page four has been intentionally corrupted with a hex editor and then opened and saved again in Gimp to remove the errors in the file. You can view the source here: https://pi-xi.net/share/colorlecture.tex and the finished PDF here: https://pi-xi.net/share/colorlecture.pdf The only modifications I've made to the simpleslides-s-BottomSquares.tex is replacing the background color, contrast color and variant color with different values ([s=.0], [r=.8,g=.2,b=.2], [s=.15]). I would appreciate if someone could explain if there are bugs in my tex sources, in MKIV or in the Adobe Reader – and in any case how can I fix the erroneous output on Adobe Reader to match it on Sumatra, Google Docs, etc. Best regards, Otso Helenius ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

[NTG-context] Hyphenating compound words in MKIV & microtypography
Hi, MKIV seems to have a problem in hyphenating long finnish compound words in MKIV (2011.05.18 22:26). Here is a minimalist example (columns added to exaggerate the problem): \mainlanguage[fi] \language[fi] \starttext \startcolumns[n=3] kolmivaihekilowattituntimittari ympäristöliiketoiminta epäjärjestelmällisyydellistyttymättömyydellänsäkään järjestelmällisentelentelemättömyydellänsäkään \stopcolumns \stoptext Similarly with en-hyphenation and \input knuth, some of the lines stretch out in an ugly fashion. What am I doing wrong? I don't have these problems in LaTeX. P.S. The punctuation characters should be partially hung out in a justified paragraph (similar to what microtype package does on LaTeX). Wikipedia says ConTeXt has "interfaces for handling microtypography" but they don't seem as apparent and as easy as using microtype on LaTeX. The wiki article Protrusion#MkIV presents \definefontfeature but I find it counterintuitive that one has to use \definefontfeature[default][default][protrusion=quality,expansion=quality] \setupalign[hz,hanging] to enable the features. It is unclear if these lines switch the features on globally for all loaded fonts (for example ttf/otf ones defined with \starttypescript). IMHO these features should be enabled by default because they produce better typographic quality by default (which should be the preference), and could be switched off anyway if wanted. The less setup lines one has to add before \starttext to get high quality results the better.

It works very well and can fetch content directly from web pages (also recognizes PubMed, ScienceDirect, Google Books etc. automatically). The best feature is automatic sync of content to either the Zotero server or your own. The Firefox plugin is nice, and now there is also an alpha standalone app in in development.

[NTG-context] Using text as a clip path for Metafun & free shape paragraphs
Thanks to Wolfgang for the instructions on changing fonts, \switchtobodyfont works as expected. I still have to dig up the exact definitions of both \switchtobodyfont and \switchtotypeface, as the latter command seems to work in Hans' examples (for example showfont.pdf) but not with my installation. Now, I've been trying to use metapost for achieving magazine type layout with ConTeXt, and have a question about the following features: 1) Is it possible to use TeX typeset text as a clipping path for MP graphics? What I would like to achieve is a similar cut mask as seen in this picture: https://modernpost.files.wordpress.com/2009/10/rockstar11091.jpg i.e. the text outline cuts a hole in the brown filled rectangle revealing the bitmap below. I can cut pictures easily with paths in MP like so: \startMPcode fill unitsquare xysized (100mm,100mm) withcolor green; picture cur; cur := currentpicture; currentpicture := nullpicture; fill unitsquare xysized (100mm,100mm) withcolor blue; path mask; mask := unitsquare xysized (100mm,100mm) -- reverse unitsquare xysized (100mm,10mm) shifted (0mm,45mm) -- cycle; clip cur to mask; draw cur; \stopMPcode But I can't cut pictures with pictures (only with masks), nor have I found a way in any of the manuals (mmakempy.pdf, metafun-p.pdf, metapostmanual.pdf) to output text outline as paths which could be used for cutting a hole in the mask picture. Is this possible? 2) MP gives an easy way to format free flowing paragraph shapes similar to this image: http://www.davidlcade.com/images/gropius/g2.png . I have followed the instructions on pages 435-444. The problem with this approach is that the text which will be placed in a freely shaped paragraph will be a separate block which won't flow freely with other text in the document body if the contents on earlier pages change. I guess this drops in the category of big feature requests, but it would be nice to be able to define the shapes and positions of ConTeXt columns/paragraphs with MP graphics. In InDesign columns of any shape anywhere on the page can be connected without having to separate one block of text from the rest. With this feature one could define for example a 2-page spread for a magazine (with free shape graphics and columns) in between two ordinarily defined pages and would not have to manually disrupt the body text flow through the document.

Re: [NTG-context] Font selection problem in MKIV
Sorry, I was in error while referring to the font sizes. The actual "limit" below which typescripted fonts stop working is 12pt and it is not tied to the \setupbodyfont setting. Any font output with 12pt or less will be formatted as Latin Modern. i.e. \switchtotypeface[Pompadour][ss,12pt] 01234567890 shows as Latin Modern whereas \switchtotypeface[Pompadour][ss,12.1pt] 01234567890 shows as Pompadour. 12pt is the default document font size so I can only guess there is some kind of a conflict.

Actually, the biggest problem is that many font related pages on the Wiki are for MKII and many lack information on whether the syntax is for MKII or MKIV. The font docs on Pragma homepages are for MKII only. Syntax for the \switchtotypeface would be nice. showfont.pdf from Pragma homepage shows \switchtotypeface[name][size,type] as one possible calling syntax but a clear explanation of all the parameters is missing. I would like to add this to the Wiki along other tutorials for MKIV font usage, so as much information on the subject as possible is appreciated.
