Tha= nks, Rik.

<= /div>

Not using Pando= c. I was using Pandoc up until 2020:

I'v= e since authored KeenWr= ite, which uses flexm= ark-java to generate XHTML documents from Markdown. The only additions = I've made to the library is to add support for Pandoc's annotation = syntax (:::).

That said, = I'm also a firm believer in not duplicating information. The informatio= n (file name extension) is already available in the documents, so adding a = classification on top of the extension feels redundant.

Thanks for the suggestion!

Thank you fo= r the suggestion Hraban.

The source comes from Markdown, which is converted to XML, then typeset using ConTeXt. There's no Markdown-specific mechanism to relate images to a particular external figure definition, unfortunately. All images use the same syntax and are treated the same way. The only part that differs is the file name extension (and header within the file).

One possibility would be something like:
\setupexternalfigure[
    width=3D1em,
    height=3D1em,
    order=3D{svg,pdf,png,jpg},
    location=3D{local,default,global},
]

\defineexternalfigure[png][
    width=3D\textwidth,
    height=3D\textheight,
]

\unprotect

\let\old_externalfigure=3D\ext=
ernalfigure

\tolerant\def\externalfigure[#=
1]#,[#2]#,[#3]{<=
span>%
    \doifelseinstring{.png}{#1}{%
        \old_externalfigure[#1][png]=
[#2]%
    }{%
        \doifelsefileexists{#1.png}{%
            \old_externalfigure[#1.p=
ng][png][#2]%
        }{%
            \old_externalfigure[#1][=
#2][#3]%
        }%
    }%
}
\protect

I was wondering if there was a simpler or a solution that's more th= e ConTeXt-way?

Thanks again!

Assuming that Pandoc markdown is being used, you should be able to set class attributes on each image. You can then associate external figure definitions with specific classes, and process each individually. (Pandoc user guide, link_attributes)
