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

Thanks for this code Hraban. I tried this last night and it worked
really well. I did have one stumbling block when I noticed that those
image files with a space in their names were not found, however
renaming without a space solved

\setupexternalfigures[

resolution=\Resolution,

With the script I get strange results. I am not sure whether the
resolution is correctly calculated.
And I am wondering what the script is doing with png files.

Whatever I insert as resolution, I get no change.

The setupexternalfigures seems to be broken. In the example below, the first
\placefigure doesnt work, but the second with the entire path does.
I'm running the latest minimals via the GUI installer on winxp.

Example:
% mptest.tex:

Hello,
the sample file hacker.jpg is only found by \externalfigure[hacker]
when using \setupexternalfigures[location=global] but not with
\setupexternalfigures[location={global,local}] nor with
\setupexternalfigures[location={local,global}]
Do I misunderstand perhaps the location-option
32 matches
