Hello,
this question in not straightly related to Context, but Context users may have solved it and Ctx may be used to solve it.
I would need to get the following information from .pdf file(s):
- number of pages, - common width and height of pages (provided that they are the same; otherwise the dimension can be e.g. zero).
There is the macro \getfiguredimensions which, amongst other things, sets up \noffigurepages, \figurewidth, and \figureheight. Here is an excerpt from a macro I have been using since 'forever': \newcount\imgcount % to store the number of pages \unexpanded\def\addimage#1{% \getfiguredimensions[#1.pdf]% \imgcount=\noffigurepages\relax \dorecurse {\the\imgcount} {\getfiguredimensions[#1.pdf][page=\recurselevel]% \ifdim\figurewidth>\figureheight ... \fi }} Best wishes, Taco
