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
