You can also pass a variable as argument in the second argument,
e.g. in the following example I set the background image with
the start of each new slide.
\setupexternalfigures[location=default]
\defineoverlay
[SlideBackground]
[\doifsomething
{\structureuservariable{background}}
{\externalfigure[\structureuservariable{background}][factor=max]}]
\setuppapersize[S6]
\setupbackgrounds[page][background=SlideBackground]
%\setuppapersize[S6][S6,oversized]
%\setupbackgrounds[paper][background=SlideBackground]
%\setuplayout[location=middle]
\definehead[Slide][chapter]
\starttext
\startSlide[title=Cow][background=cow]
\dorecurse{3}{\dontleavehmode\page}
\stopSlide
\startSlide[title=Hacker][background=hacker]
\dorecurse{3}{\dontleavehmode\page}
\stopSlide

> Can I set the offset in this way, too?
It depends on your requirements, to get equal bleed on all
four sides you can just increase the width/height of the image
with the offset value.

Hi,
Hi,
I have corrected for the dimensions of the ellipse but I cannot achieve the
same effect for the red color.

On linux instead of writing the full path I'm using the command "alias" in my ".bashrc" file. So, Adityas proposal on mtxrun (Date: Wed, 12 Feb 2020 00:24:21 -0500 (EST)) becomes: alias context='~/context-lmtx/tex/texmf-linux-64/bin/mtxrun --autogenerate --script context' with 'context-lmtx' being the directory, where I installed context. With this you invoke your context file with "context your-file.tex" I cancelled all context stuff in my PATH variable. Don't forget to 'source ~/.bashrc' afterwards. > 2) avoid putting [lmtx path]/bin in PATH, Yes, this could be a solution too, in my opinion. > 3) putting [lmtx path]/bin _after_ [lmtx path]/tex/texmf-linux-64/bin in > the PATH > > I'm asking here because option 1 is correct but not very handy, while 2) > and 3) are different from what the installer says and they seemed to give > other problems when I tried them.

As Hans said (and also what I wrote in my message) is that you have to run the one in ~/context-lmtx/tex/texmf-linux-64/bin/ This shows that the wrong binary is being used. You are using the binary in /home/sam/context-lmtx/bin when you should use /home/sam/context-lmtx/tex/texmf-linux-64/bin. I ran into a similar problem in the past because the installation script install.sh says the following, among other things: "If you want to run ConTeXt everywhere, you need to adapt the path, like: [lmtx path]/bin:[lmtx path]/tex/texmf-linux-64/bin:[the rest of my path]" Doing as suggested, when mtxrun is launched the first binary is used because [lmtx path]/bin comes first in the PATH.

I always follow 2. I don't think that [lmtx path]/bin should ever be in the PATH except when updating the installation.

Is this defining and setting in one command? Can I set the offset in

i Henri,
Thank you for your answer. The idea is to make the graph as an attachment. I
converted to Metapost but the road is still long!
The code is from percusse on StackExchange. As you can see, there is a
