[NTG-context] OT: Pdf info
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). The final goal is to use Ctx as a .pdf joining engine - to provide this, I need to know whether the .pdf to be inserted is portrait or landscape oriented, what is its size (so if to be scaled or not) etc. So Lua inside Ctx may be used to get the required .pdf info, if necessary. If an external program was used, it should be non-interactive (command-line oriented), free and working under Windows. Does anyone have any experience with such a task? Kind regards, Lukas -- Ing.

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 }}

[NTG-context] highlighting aligned formulas
Hello, Is it possible (using ConTeXt MKII) to put a frame (and/or other highlighters) around an aligned multiline formula, and also around a single line of this equation array? (The equation number should align correctly outside the frame.) \mframed within an alignment seems to refuse the job. Digging the mailinglist brought up a 2006 hint of Hans referring to a \definealigned command which I also could not bring into action.
