PDF Studio (that I try to establish as a cheap alternative to Acrobat Pro) sometimes shows an error after asking if I’d like to activate JavaScript and won’t open my form document at all.

Now it seems to use options of the PDF form fields that look different in viewers and disappear if I delete the field… Custom symbols of radiobuttons and checkboxes are displayed constantly (that used to work only in MkII 10 years before or so, probably due to changes in Acrobat), and it’s not possible to use different symbols for checkend and unchecked Hraban Am 2019-08-05 um 10:03 schrieb Henning Hraban Ramm : Hi, coming back to an old form project I find that something changed WRT to form fields.

Regardless of my other mails, I’d appreciate to have this bug fixed.
Last time I checked this (widget crap) there was an issue with acrobat
and apearances ... I think that this model of parents and kids never
really worked well and when one switches a page existing renderings get
messed up. Irr some of these widgets (check boxes?) can't even have a
custom visualization any more that is kept when one goes through pages.
I also have no clue to what extend all this is part of the 'standard'.
Anyway, if you can make a working example (uncompressed pdf) in official
acrobat (not some other tool) that works in acrobat reader we can maybe
figure out what todays demands are. Implementing stuff like this is
trivial but the trial and error is painful.

Hi,
this looks very promising!!
Since you ask for feature requests:
1) 3d support. This is of course a very big request, but it would also be
useful for many people.
2) About graphing, it would be nice to be able to do contour polots and
density plots. I know I asked for contour plots some time ago, and there
were some examples, but I don't think there was ever some built in support
for it. Maybe that can be done "easy" with help of lua? I guess there exist
good algorithms.
3) (small) The possibility to have arrows in coordinate axes. I have not
had the possibility to test the new features today, and maybe this is
already built in (drawarrow?), but I mention it since I did not see it in
the pdf.
Again, it is very nice that you work on extending MetaPost/MetaFun further!!

it doesn't, it just connects the dots, so, just use a smaller step, like
xstep = .01
(The upcoming luagraph module will provide some interpolators so at some
point we can hook these in.)

Printed copies will reside below my desk until the meeting. The Table of Contents is online at: https://articles.contextgarden.net/journal/2018.html The PDFs are not yet publicly available but current CG Members can send me an email for an advance copy of any of the article PDFs.

If you would like to visit the castle with us, you should register now :) = ConTeXt Meeting blurb = If you have not registered yet, please consider joining us at ’t Sjetootje, Bassenge-Boirs, Belgium on September 16–21, 2019. The ConTeXt meeting is an excellent way to get help with any problems you may have in ConTeXt, to learn about future directions of ConTeXt and LuaTeX, or just to talk and have a drink with other ConTeXt users. You do not have to be a ConTeXt Group member to attend the meeting, but members do get a meeting fees discount worth more than the CG membership fees for a year. In fact, if you attend for the very first time, there is an extra discount for that as well. For registration and other information, see the website at https://meeting.contextgarden.net/2019 The 13th ConTeXt Meeting is sponsored by Dante e.V (www.dante.de) and NTG (www.ntg.nl), as well as by Pragma ADE (Hans & Ton) and Bittext (Taco). We are very grateful to all our sponsors! = Chaos Communication Camp = CG Board member Henning Hraban Ramm is representing the ConTeXt community at the Chaos Communication Camp 2019 in the 'LaTeX Village’ (set up in conjunction with Dante e.V.) https://events.ccc.de/camp/2019/wiki/Village:LaTeX If any of you are in the neighbourhood of Ziegeleipark Mildenberg, Zehdenick, Germany between August 21 and 25, I am sure he would love to see some visitors (Zehdenick is about 60km north of Berlin). = Board elections = The ConTeXt meeting is also the location of the annual CG membership meeting. This year, no less than four board members are forced to resign according to the bylaws. We are looking for CG members to help fill those spots in the board. If you are interested in joining the CG board, please send a message to any of the current board members and we will get in touch with you. We can really use the help! Our previous newsletter already provided one tentative new board member, but ideally we would like at least one more candidate. = Becoming a CG member = Our official stated purpose: * to promote the ConTeXt typographic system; * provide its users with infrastructure and information; * support its development; * provide a platform for discussion of quality automated typography; * serve as a meeting place for people who want the best possible typography for the languages and writings of the world; * organise congresses and trainings for users and ConTeXt developers to meet; * provide financial support to those involved in documentation and ConTeXt development, including through their participation in conferences; * produce and sell printed materials on ConTeXt; * sell advertising items for ConTeXt. The more members we have, the more we can do. If you are not a member already, please consider registering at https://group.contextgarden.net/register.shtml Membership fees are €40 per year for normal members, €20 for students, and €200 for institutions and corporations. = That’s all for now = Keep happy ConTeXting!

Re: [NTG-context] metafun 2
Dear Hans,
I just wanted to ask, will LMTX and MetaFun remain valid implementations
of TeX and MetaPost or do we have to expect incompatibilities?
Cheers, Henri

[NTG-context] metafun 2
Hi,
In the process of providing an additional (more abstract) interface to
some of the old and also new MetaFun code we wonder what kind of
features users would like to see.
http://www.pragma-ade.com/general/magazines/mag-1104-mkiv.pdf
As a teaser I uploaded a MyWay document that shows some of what is
coming. All is experimental but it shows the direction. We're talking
ConTeXt LMTX here. For instance,
draw lmt_outline [
content = "hello",
kind = "reverse",
fillcolor = "darkred",
drawcolor = "darkblue",
rulethickness = 1/2,
] ysized h shifted (3.75h,-1.25h) ;
Wraps all the outline drawing in one macro with a set of options (there
will be xml interface definitions for that). Or take:
draw lmt_followtext [
content = "How well does it work {\bf 1}! ",
path= (fullcircle scaled 4cm),
trace = true,
spread = true,
] ysized 5cm ;
which is an easier interface to text along a curve. Arrows can be drawn
with
draw lmt_arrow [
kind= "draw",
location= "middle",
alternative = "curved",
path= fullcircle
scaled 3cm
shifted (3.5cm,0cm),
] withcolor "darkblue" ;
but of course the low level interface with its many variables for
tweaking stays around. Other examples are shown in the mentioned document.
So the question is: What do you miss in metapost support? Of course it
should fit within the concept, so 'artistic freehand drawings' is not
something that is likely to get interfaced. We are particularly
interested in educational applications, if only because ConTeXt started
out that way.
