Getting number of figure pages in MkIV

Getting number of figure pages in MkIV

[Aditya Mahajan]

Hi,

What is the correct way of getting the number of figure pages in MkIV. The 
following, which works in MkII, always gives 0 is MkIV.

\getfiguredimensions[filename]
\noffigurepages

Thanks,
Aditya

in grph-inc.mkiv we need to add a check pass for this

    \ifconditional\testexternalfigureonly
       \ifcase\figurestatus \else
         \ctxlua{figures.check()}%
       \fi
       \signalexternalfigure
    \else

or maybe even

    \ifconditional\testexternalfigureonly
       \ifcase\figurestatus \else
         \ctxlua{figures.check()}%
         \ctxlua{figures.scale()}%
       \fi
       \signalexternalfigure
    \else

This works perfectly.
