Hello,
I'm trying to handle a special problem. I guess ConTeXt would be useful for this purpose, although its primary function is to typeset. But -
I have many drawings - they are black-and-white one-sided PDFs of A1 or A2 size (typical technical drawings).
The bottom right area of size 210 x 330 mm should be "deleted" - or over-painted by a white rectangle (or picture or MP code).
And next a new PDF of A4 size should be placed on the right bottom area, just on the white ("deleting") area.
I wouldn't have problem with batch processing the number of files.
But I would need an example how to take the original A2 PDF, place a whitening area on it and then to place a new PDF over it; I'm not experienced enough in "layering" with ConTeXt and I guess this may be the way.
Would it be possible to provide a small example of such processing an arbitrary file? I always use this as starting point http://wiki.contextgarden.net/Layers -- luigi
