t-downsample.lua

Hi, Please find attached a new version of the module, with some ideas from Marco. Later, I'll upload it to modules.contextgarden.net. Here a usage example: \usemodule[downsample] \setupexternalfigures[ location=default, % find hacker.jpg and mill.png cache=/tmp, % where to put the low resolution images resolution=50, % resolution in DPI conversion=downsample.pdf] % use this module \starttext \externalfigure[hacker][width=0.4\textwidth] \setupexternalfigures[resolution=20] \externalfigure[mill][width=4in, height=3in] \setupexternalfigures[resolution=200] \externalfigure[mill][width=4in, height=3in] \stoptext Hans, it would be nice, to apply this patch, to trigger new conversion, when figure dimensions change: --- grph-inc.lua~ 2019-02-14 17:04:12.000000000 +0100 +++ grph-inc.lua 2019-02-17 08:45:38.129971581 +0100 @@ -864,6 +864,14 @@ newbase = prefix .. newbase end local hash = "" + local width = figures.current().request.width + local height = figures.current().request.height + if width then + hash = hash ..

Status of Asymptote
by Alexandre Christe 11 Jan '24

11 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.

new uplaod
by Hans Hagen 17 Apr '23

17 Apr '23

Hi, I uploaded a new lmtx. Again some updated math of which details will be revealed later. Apart from some details we added suport for fourier notations. There are no high level definitions yet as we have to invent names but this is how it works (private unicode slots might change): \setupbodyfont[pagella] \starttext \setupmathdelimited [topoffset=.2\exheight] \definemathdelimited [fourier] [rule=no, left=\zerocount, right="FE944] \definemathdelimited [courier] [rule=no, left=\zerocount, right="FE946] \definemathdelimited [xourier] [rule=no, left=\zerocount, right="FE948] $ \fourier{(z+1)} $ $ \fourier{(z+1)} + \sqrt[2]{1}$ $ \fourier{(z+1)} + \courier{(z+1)} + \xourier{(z+1)} $ $ \fourier{\left(z+\frac12\right)} + \courier{\left(z+\frac12\right)} + \xourier{\left(z+\frac12\right)} $ $ \autofences \fourier{(z+\frac12)} + \courier{(z+\frac12)} + \xourier{(z+\frac12)} $ $ \widehat{x^2 + 2x + 2} $ \stoptext This example also shows a new \autofences feature and widehats (widetilde and widecheck also work that way) that overcome limitations in fonts, so \def\CrappyHack#1{\im{#1{a} + #1{a+b} + #1{a+b+c} + #1{a+b+c+d} + #1{a+b+c+d+e} + #1{a+b+c+d+e+f}}\par} \CrappyHack\widehat \CrappyHack\widetilde \CrappyHack\wideacute \CrappyHack\widecheck will work. For thise in finance we now have $ \annuity{x + 1} + \lannuity{x + 1} + \rannuity{x + 1} + \lrannuity{x + 1} $ these are basically radicals (like sqrt) with two sided symbols.

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.
