Dear list,

I wish to do several zoom from a picture made in MetaFun, from a pdf file which name is given on the commande line, like:

context zoom.tex —File=EntryFile —Page=9 —result=OutFile.pdf

Minimal example:

\starttext

numeric ThePage ;

string FileName ; 

FileName := \getdocumentargument{File} ;

ThePage := \getdocumentargument{Page} ;

draw textext("\externalfigure["  & FileName &"][page="  & ThePage &"]") xysized (48in,48in) ;

  \stopMPpage

\stoptext

I can get in the MPpage the page number in entry (9 in my example), but not the file name. 

Thanks for any help.

Fabrice.
