Hello,
I have some problems with the way to put clipped images in ConTeXt
documents; for what I can see the correct way to do it is via
something like:
\clip
[width=6.3cm,height=10.5cm,hoffset=0.5cm,voffset=1cm]
{\externalfigure[ciccione_03.pdf]}
Now suppose that I wanted to put the above thing zoomed 200%;
and here I have two problems:
(a) I can't seem to find the proper number to pass on to scale= or
factor= in the \externalfigure options
(b) AFAICS I need to scale all the clipping parameters as well.
Point (b) is particularly annoying; is there a way to "pre-clip"
an image, without touching the original file? It should be
possible to specify clipping area at inclusion time (LaTeX's
graphicx package can do that ...), and therefore in a
scale-independent way (this is especially important when the scale
factor is something like "max" or "fit" or "broad").

So you want to clip first and scale the result to 200%? Or do you
wish to clip the enlarged figure?
\scale[sx=2,sy=2]{%
\clip [width=3cm,
height=5cm,
hoffset=0cm,
voffset=0cm]{\externalfigure[cow]}}

this can't be done with the above.

in addition to other answers: you can always surround it with \scale[..] ...
