empty line before typebuffer
by Henning Hraban Ramm 31 Jul '23

31 Jul '23

Yet another issue: \typebuffer always starts with a blank line. Is this a bug, or how can I disable it? Hraban MWE: """ \starttext \startbuffer \samplefile{tufte} \stopbuffer \framedtext{\typebuffer[option=tex]} \stoptext """

caption for moved sidefloat in the margin
by Henning Hraban Ramm 30 Jul '23

30 Jul '23

Hi again, I’m reading through the details manual and set up some figures as sidefloats that are offset to the margin. This works well. Now I’d like to have their captions in the margin, below the figure. If I set location=innermargin, then the caption is beside the image, i.e. somewhere at the edge. If I don’t, I can’t get it to move to the left edge of the image. How can I do that? Hraban """ \useMPlibrary[dum] \setuplayout[ backspace=5cm, width=12cm, ] \definefloat[marginfigure] \setupfloat[marginfigure][ leftmargindistance=-\leftmargintotal, rightmargindistance=-\rightmargintotal, default={inner,none,low,high}, ] \setupcaption[marginfigure][ style={\ss\tfx}, align={flushleft}, width=\leftmarginwidth, %location={innermargin,low}, ] \starttext \showframe \startplacemarginfigure[ location={inner,3*hang}, title={My caption should be flushleft and aligned with the image.}, ] \externalfigure[dummy][width=.66\textwidth] \stopplacemarginfigure \samplefile{lorem} \stoptext """

Hi, I’d like to use a custom buffer ("MyBuffer") to use a custom typing style ("MyCode"). How does that work?

issue with current latest (2023.07.28 20:04)
by Pablo Rodriguez 29 Jul '23

29 Jul '23

Dear list, trying to generate the format for current latest (2023.07.28 20:04), I get this error message: tex error > tex error on line 280 in file lang-lab.mkxl: Control sequence expected instead of undefined \lang_labels_define_class_indeed {head}{ <macro> \definelabelclass ...ded {\lang_labels_define_class_indeed {#1}{\ifchknumber #2\or \lastchknumber \else \zerocount \fi }\expandafter \noexpand \csn ... <line 3.280> \definelabelclass [head] [0] % titles <empty file> You injected something that confused the parser, maybe by using some Lua call. LuaMetaTeX is from 20230727 (just in case it might be relevant). Could anyone confirm the issue? Many thanks for your help, Pablo

Re: setupexternalfigures and resoĺution
by Benjamin Buchmuller 28 Jul '23

28 Jul '23

This thread about downsampling external images on the fly is a really helpful feature! Thanks, Hraban for sharing the code! I was wondering if it was possible to downscale also raster images embedded in pdf/svg files loaded via \externalfigure? I found a ghostscript solution online (https://stackoverflow.com/questions/9497120/how-to-downsample-images-within…) gs \ -o downsampled.pdf \ -sDEVICE=pdfwrite \ -dDownsampleColorImages=true \ -dDownsampleGrayImages=true \ -dDownsampleMonoImages=true \ -dColorImageResolution=72 \ -dGrayImageResolution=72 \ -dMonoImageResolution=72 \ -dColorImageDownsampleThreshold=1.0 \ -dGrayImageDownsampleThreshold=1.0 \ -dMonoImageDownsampleThreshold=1.0 \ input.pdf Now, I'm wondering how to adapt grph-downsample.lua to do this? I've tried: \setupexternalfigure[ resolution=\Resolution, conversion=lowres.pdf ] And added to grph-downsample.lua local function sample_down_pdf(oldname, newname, resolution) print("DOWNSAMPLE sample_down " .. oldname .. " to " .. newname) -- MkIV: -- local image = img.scan{filename = oldname} -- LMTX: local image = figures.getinfo(oldname,1) image = image.status.private local s = format("gs \ -o \"%s\" \ -sDEVICE=pdfwrite \ -dDownsampleColorImages=true \ -dDownsampleGrayImages=true \ -dDownsampleMonoImages=true \ -dColorImageResolution=%s \ -dGrayImageResolution=%s \ -dMonoImageResolution=%s \ -dColorImageDownsampleThreshold=1.0 \ -dGrayImageDownsampleThreshold=1.0 \ -dMonoImageDownsampleThreshold=1.0 \ \"%s\"", oldname, resolution, resolution, resolution, newname) print("DOWNSAMPLE Conversion: " .. s) os.execute(s) end figures.converters["pdf"]["lowres." .. "pdf"] = sample_down_pdf But I must be missing something as the code doesn't seem to be called. Any suggestions? Thanks! Ben

Link from a PDF to a reference of an embedded PDF
by Gerion Entrup 27 Jul '23

27 Jul '23

Hi, I found the "interaction" parameter in the documentation for setupexternalfigure/externalfigure [1]. I, however do not quite understand it. When embedding another PDF with this command, it seems to be possible to include the references of the underlying PDF. It is possible to link to them within the main context document? In [2], I found something maybe related but it requires a tuc file. Example: inner.tex: ``` \starttext \startsection[title=References, reference=sec:ref] Some text \placeformula[eq:foo] \startformula 1 + 2 = 3 \stopformula or: \startitemize[n] \item[item:bla] bla \item[item:blub] blub \stopitemize Find all references \in[sec:ref], \in[eq:foo], \in[item:bla], \in[item:blub]. \stoptext ``` outer.tex: ``` \starttext \externalfigure[inner.pdf][width=10cm, interactive=reference] Find all references \in[sec:ref], \in[eq:foo], \in[item:bla], \in[item:blub]. \stoptext ``` Can I somehow access the references of inner.tex from outer.tex? For me, it is not that relevant, that the correct number is set, but the interaction within the outer PDF should work, so clicking on the reference should scroll to the correct content. Background of my question: I normally do graphics in a separate PDFs. Some graphics consists of source code together with a graphical representation and I want to be able to link to single source code lines.
