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"). -- Giuseppe "Oblomov" Bilotta

\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:
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]}}
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").
this can't be done with the above. Pat

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