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).
An important question: overpainted for your personal needs or in order to remove some information from PDF that others are not supposed to see? Mojca
