When I define rgb colors AND use not-print-modus I get the right rgb colors in the pdf. When I define cmyk colors AND use print modus I get colors that might be correct (tested next week) But obviously it is not possible to define both color spaces in \definecolor because I don't get the same colors in the pdf as with the cmyk-only defined file. Maybe I misunderstood this, I've got a hint here, that I could define rgb and cmyk in the same \definecolor and choose the right color space in \setupcolors. The correct method of defining rgb AND cmyk in the same file would be to put the definecolor command inside a startstopmode-environment. Can someone confirm this? > > (2) > > I think so.

Re: [NTG-context] Issues with RGB to CMYK conversion with color profiles (was: Colormanagement)
Hi Jan, I donno if things have changed (ConTeXt is a fast moving target), so take my answers with a grain of salt. (1) AFAIK there is no ACTIVE color management in ConTeXt in the sense that there is an automatic color conversion from one profiled(!) colorspace into another profiled color space. This means that all given colors (objects) have to be in the correct (profiled) color space already! Objects with embedded color profiles (e.g. a PDF bitmap graphic with icc profile) will use those. Objects without a profile will use the corresponding "default" color space profiles. These default color space profiles can be defined via "profile" in \setupbackend. This way every color in the PDF is defined properly. (2) I think so. Can't test, because my Windows 10 is beyond repair after three "upgrades" and Acrobat is not working properly anymore. (3) Judging from the size of the final PDF, the icc profile is not embedded. The profiles have to be installed in "the right place" (this includes ConTeXt but also the PDF viewer software). See "ICC profiles" section at https://wiki.contextgarden.net/PDFX (5) see (1) and (3) Hope this helps, Peter Am 2018-11-14 um 11:39 schrieb Jan U.

The most I can do is edit or duplicate things (like snippets for example) to my liking. But for instance, I would like to change the command so that it behaves like the LaTeX bundle (compiling, calling Skim, autorefreshing when compiled again) and also copying the "watch document" from that bundle, but that's out of my reach.

ConTeXt, but I don't think there's an _updated_ structured introduction. For instance regarding fonts I read here https://tex.stackexchange.com/questions/448812/the-definitive-guide-to-context-mkiv-documentation/448813#448813 that the latest documentation is http://www.pragma-ade.nl/general/manuals/fonts-mkiv.pdf But going there it goes to much depth and I don't know if I need simplefonts, definefontfamily, setupbodyfont, starttypescript, etc. and even seeing that may be those can coexist, I don't know what's the use case for each one. I remember when I started with LaTeX there was a huge number of beginner-intermediate documents (many of which I now wouldn't recommend even to my worst enemies, but at least there were many to read), but here there are much less, and those that seem complete you see they are from early 2000s (and with how much it changes in ConTeXt you don't know what to believe). I know TeX core enough to know how it works, LaTeX enough to know how it's expected to work (and if I don't know something, I know where to look), but ConTeXt I don't know where to find introductory updated material, and also some text about the whole way context organises everything (how files are organised, project structure, how setups work, etc., kind of a whole idea to know where to look when there's doubt about certain area). Also there's this list, but one does not feel like spamming this list sharing newbie questions with those of people that actually work with this system.

Re: [NTG-context] Issues with RGB to CMYK conversion with color profiles (was: Colormanagement)
Hi all, attached you find my colormanagement tests and I need your help to understand and debug the situation. I am testing together with a friend of mine, a professional colormanager, who does not know ConTeXt. There are several files in the archive: The differences in the files are the color definition and the color profile used. - rgb-xxx.tex – colors are defined with RGB values only. - rgb-cmyk-xxx.tex – colors are defined with RGB and CMYK values. The cmyk colors are derived from the rgb values using gimp and the color profiles sRGB/ISOCoated - cmyk-xxx.tex – colors are defined with CMYK values only. The xxx stand for two color profiles: iso-coated and swop. What I see is this: Colors in pdfs are the same no matter what color profile I choose. With rgb values and rgb/cmyk values I get the same colors in pdf (the wrong ones). With cmyk values only I get other colors in pdf. Next week my friend will test if these are the right ones. I have many questions: 1. Is colormanagement working in ConTeXt at all? 2. Is my code correct? 3. Why do pdfs with different color profiles show the same colors? 4. Why does ConTeXt not take the cmyk colors from \definecolor when there are rgb values as well? 5. Where can I define a coresponding rgb profile? In Scribus you have to define two profiles (eg. sRGB and ISOCoated) to make colormanagement work.

[NTG-context] TextMate ConTeXt bundle
Hi all, After some years with LaTeX and let's say three or four times trying to start with ConTeXt, I decided to try again. Difficult, there are many manuals and a lot of contradicting ideas (at least for those of us that do not know) in them, but still, I want to try to see if once and for all I can manage to dominate it. I have installed MacTeX 2018. I use TextMate, and the ConTeXt bundle is not working in Mac OS High Sierra. After installing it, when I tried to compile it said something along the lines "your PATH is ... you should have 'context' in your path", so I searched in my computer and changed TextMate PATH to: $PATH:/opt/local/bin:/usr/local/bin:/usr/texbin:/usr/local/texlive/2018/texmf-dist/scripts/context/stubs/unix And this last part is where I think the context binary seems to be /usr/local/texlive/2018/texmf-dist/scripts/context/stubs/unix But now when I run it it says env: texlua: No such file or directory What could be happening? What do I do? Also, the bundle was last updated in 2010, may be there are new things? Where could we learn what things to add? https://github.com/pgundlach/context.tmbundle Any updated documentation that takes you from beginner to intermediate would be apreciated too.

[NTG-context] Server upgrade planned for Nov 26.
Hi all, We plan to update the software installation on the zapf.ntg.nl server on Monday Nov 26. As a consequence, various tex-related sites including www.ntg.nl, wiki.contextgarden.net and www.luatex.org, as well as the mailman lists @ntg.nl, will be down for some as-of-yet undetermined amount of time. We’ll try to be fast, but one never knows with these things...

Both the list and the citation are sorted on "authoryear". But the orders in
the pdf are different. Is this a bug in ConTeXT?

Yes indeed. I do not need a general solution (as that would be way too
complicated). But is there a nice way to fine-tune the rendering on the
spot? (In this case, I only need to have the first character capitalised, in
a few occasions.)
Thank you for your reply,
All the best,
