This works well, but what I'd like to do is choose a fixed
size frame
for each PDF and have ConTeXt fill the frame in the same
way as these
CSS commands:
object-fit : cover;
object-position : top left;
overflow: hidden;
(http://www.w3.org/TR/css3-images/#the-object-fit)
Many thanks -- although I don't see the effect I'm trying to get.
In the code below the cow picture should fill the three frames at
three different scales with no white bars between the frame and
the externalfigure frame:
\setupexternalfigures[location={default}]
\starttext
\framed
[offset=overlay,width=10cm,height=2cm]
{\externalfigure[cow][frame=on,factor=max]}
\framed
[offset=overlay,width=4cm,height=8cm]
{\externalfigure[cow][frame=on,factor=max]}
\framed
[offset=overlay,width=6cm,height=6cm]
{\externalfigure[cow][frame=on,factor=max]}
\stoptext
Thanks,

[NTG-context] Trying to emulate CSS object-fit behaviour...
Hi,
I have a collection of PDF files of varying sizes and aspect ratios.
I'm currently using a combination and external figures to place these
into frames:
\setupexternalfigures[width=45.2mm, frame=off, factor=fit]
\setupcombinations[nx=5,ny=4,width=277mm,distance=10mm,after={\blank[10mm]}]
\setupframed[offset=1.0mm,background=color,rulethickness=0.25pt,backgroundcolor=white,framecolor=lightgray]
\starttext
\startsection
[title={title text}]
\placefigure[here][nonumber]
{\vspace more text}
{\startcombination
{\framed[]
{\externalfigure[1.pdf][location=middle]}{}}{}
%% and so on
This works well, but what I'd like to do is choose a fixed size frame
for each PDF and have ConTeXt fill the frame in the same way as these
CSS commands:
object-fit : cover;
object-position : top left;
overflow: hidden;
(http://www.w3.org/TR/css3-images/#the-object-fit)
That is, scale the PDF until all the frame is covered with some part
of the PDF, even if means overflowing the frame. The overflow:
hidden would then clip the overflow to the frame. Different PDF's
could have different scalings applied to make this work, which is fine
for this application.
I understand this may not be an idiomatic use of ConTeXt--any advice
or suggestions for alternate approaches much appreciated.
Stu

[NTG-context] [metapost] mptopdf from the command line in ConTeXt minimals?...
Hi, I'm a ConTeXt and Metapost newbie, so apologies in advance if this is a stupid question. I've successfully installed ConTeXt minimals on an OS/X 10.6.x system and it seems to be running okay. I'd like to run some metapost examples from the command line and mpost also seems to be running well. I've seen references to a mptopdf script and there is a Perl script of that name but it looks like it needs to be installed somewhere. Is there some post-setup procedure I need to follow to access mptopdf or another one I've seen references to fmtutil?
