Status of Asymptote
by Alexandre Christe 10 Jan '24

10 Jan '24

Dear all, I'd like to know what is the status of Asymptote in Context. To my knowledge, metapost/metafun only support 2D (except with the additional libraries from Roegel, which would have to be cleaned up a bit). Otherwise, what shall be used for 3D drawings in Context? TikZ? Something else? Thanks in advance. Alex

Re: [NTG-context] checkbox in fields show the word yes
by Andres Conrado Montoya 05 Oct '23

Firefox doesn't show the "yes", nor Acrobat X, but SumatraPDF does. I modified your definition as: \definefield[test][check][cbox][][] And now the "yes" doesn't appear. However, I don't know how this affects the functionality of the form. -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

Convertnumber with \ref[number] fails in MkIV, works in LMTX
by Rik Kabel 06 Dec '22

06 Dec '22

Hello list, The following fails with ConTeXt ver: 2021.10.24 21:45 MKIV but works with the companion LMTX. The error message is:tex error > tex error on line 6 in file G:/TestConTeXt/convert.tex: ! Incompatible glue units , pointing to the second \convertnumber line. \definelabel[XX]%[text=,before=,after=,alternative=inright] \startTEXpage[offset=2em] abc\XX[xx]\par \ref[number][xx] · \convertnumber{r}{1} · \convertnumber{R}{\ref[number][xx]} \stopTEXpage In this case I am trying to display with roman numerals the number generated in the label created through \definelabel. Suggestions welcomed. -- Rik

TeXGyre Heros on Firefox
by juh 19 Oct '22

19 Oct '22

Dear all, there were some discussions on pdf viewers on the list and I know that things are not always fine. I now have a problems with the Firefox pdf viewer and TeX Gyre Heros. The font looks uneven in FF, no problems elsewhere. When I scroll into the pdf to set the display to 150% or more the font shows up just fine. So it seems to be a display problems with firefox. I tried several pdf versions no change. My configuration: \definefontfamily[mainfont][serif][texgyreheros] \definefontfamily[mainfont][sans] [textgyreheros] \definefontfamily[mainfont][mono] [texgyrecursor][features=none] \definefontfamily[mainfont][math] [texgyrepagellamath] \definefallbackfamily [mainfont] [rm] [Latin Modern Math] [scale=0.925, range=0x22C0] \definefontfeature[smallcaps][script=latn, protrusion=quality, expansion=quality, smcp=yes, onum=yes, pnum=yes] \setupalign[hz,hanging] \setupitaliccorrection[global, always] Is there anything I can do? And the is another issue: To my big surprise ArialBold MT is included into the file. I am using the current lmtx. If you want to see the effect, download the pdf. https://www.hostsharing.net/publikationen/vereinshandbuch/ Just click on "Anonym herunterladen" no need to register.

colors and contours in luametafun
by Jacob Kauffmann 23 Jun '22

23 Jun '22

Dear list, I am a huge fan of the new metafun interface. Hans asked for luametafun requests, so here are a few. - color by value in lmt_surface We want to show a surface plot of a function where the color indicates the function value (instead, or in addition to a light source). The easiest would be to have variable cf for the brightness factor (as it is), and in addition variables such as zt, minz, maxz, akin to the color formatter for lmt_contour. This becomes handy when colors are to be aligned with function values (e.g. negative = blue, zero = white, positive = red, see MWE attached). - controlling line levels in lmt_contour It would be convenient if certain levels could be set by the user. E.g. to make sure the zero level contour line is included. The user interface could potentially take a list, levels = { -1, -.5, 0, .5, 1 }, of contour level lines. See MWE attached. From my understanding marching squares can do that. A possible reference implementation could be QuadContourGenerator [1] in matplotlib, a bit of description can be found in [2]. - colormaps Contour plots often use rather complex colormaps, such as jet, rainbow or veridis. They are optimized for perceptual resolution, color blindness, screen/print or certain use cases. The functionality is already there, but from a user's perspective, it would be much easier if some of these were provided by the interface. The interface could be color = "colormap('jet')(l/n)". Indeed, these are useful in other use cases as well, such as bar charts, surface plots or shades. One rudimentary example is in the attached file. - number of levels in lmt_contour (potential bug) The number of levels is different from the user's input. Depending on the output range it can be lower or higher (see MWE attached). Cheers, Jacob Kauffmann [1] https://github.com/matplotlib/matplotlib/blob/96ff1146ad053c5c7481efd9de039… [2] https://github.com/matplotlib/matplotlib/blob/96ff1146ad053c5c7481efd9de039…

overfull gone?
by Steffen Wolfrum 07 Jun '22

07 Jun '22

Hi, in order to easily see overfull lines I used \overfullrule30\points : this gave a clear black box in the right margin. Is this command (\version[temporary]) gone?? Please have a look at the example below: no overfull indicator ... Steffen --- \setuppapersize[A6] \setupexternalfigures[location={default}] %\version[temporary] \overfullrule30\points% < BLACK BOX? \starttext \startcolumns[n=3] % Overfull lines will have slugs in colum margins. \input linden % Underfull hboxes get no warning x \stopcolumns \stoptext

How do I turn off indentation inside a \framed with align=?
by Gerben Wierda 03 Jun '22

03 Jun '22

I have these kinds of statements \framed[frame=off,align=flushleft,width=\textwidth]{\phrasetext{metamodelexplanation}} but the text inside the frame is typeset with indentation. I tried \setupindenting both before and after \starttext, (none,no,never) but that doesn’t work. How do I turn indenting off in all frameds with align=flushleft or otherwise *everywhere*?
